Well, with the video being sponsored by Warthunder, there is a non-zero chance, someone will leak classified documents proving the real top speed of the USS Nimitz is above 37.18 mph.
@@frozenstar7048 Questionable, considering hull speed and propulsion. The official fastest ship is waterjet propelled, is a wave-piercing cat and goes about 67.
We already have dudes in the comments section here saying they served aboard and they're actively hinting at the real number. It actually reminds me of how in WWII the Brits found that it was better to hire women for top secret work because they didn't blab idly like the men did.
That awkward moment when the most recent classified data leak at my work was some moron sending a reply all with some subsafe propaganda that included the speed of a sub. (relax it was a classified document being sent to people with clearence. It was their computers that received the data didn't have clearence to store or transmit classified files. )
I have been told that if you were to floor a Nimitz from zero, it would almost pop a wheelie. Im sure the guy was slightly exaggerating, but he did make it very clear they were a lot faster than we are told publicly.
I was stationed on the USS South Carolina CGN 37 in 1975 during post commissioning yard work sea trials. We were one of the escorts for the Nimitz. I can tell you during the sea trials we were going well over our official max speed of 36 knots, and the Nimitz passed us and walked away at a substantially higher speed.
I have also witnessed this phenomenon from the deck of the USS Butte AE27, you just can't imagine that much mass accelerating so quickly and moving away that fast. One of those rare moments where your brain cannot compute what the heck your eyes are seeing....
I was on the Worden CG-18 and we were a twin screw double boiler. 33mph may not seem fast but when you displace 4000 tons, it's pretty damn quick. The California did a high speed run along side of us and it passed us and it's much much bigger.
I was thinking the same thing, the top speed of military vessels is classified and a more conservative number is publically recorded, from my time in the RAN, USN carriers were said to do close to 50 knots.
The number for Aircraft Carrier speeds is the OFFICIAL maximum speed. I served on CV-60 (USS Saratoga) in the early 1980's, during one of our sea trials we topped 40 knots (46mph/74kph) for over an hour.
Naah. The speedo was adjusted for propaganda purposes. You fell right into the trap, my friend. 🤭 It's kinda like fitting weird-sized wheels to cars to give (apparently) phenomenal top speeds. (I'm kidding. Everybody knows that cars make lousy aircraft carriers.)
Wind, and sea conditions. In perfectly optimal conditions I believe it, but the official number probably couldn’t be tested and certified in those conditions as they are rare, or it was put into a computer program that gave the speed number, and it uses an average of sea conditions for its calculations.
@@EleanorPeterson Actually the radar system I worked on needed extremely accurate speed, yaw, roll and pitch data since it could do a hands-off landing. The only data we used from ship systems was speed, everything else was internally measured to less than 0.1 degree of accuracy.
@@Nordic_Mechanic that video was for domesticated ducks, for wild ducks there isn't a much better way than they picked it up in the video without it getting away. picking up ducks is still a bad idea, they will bite you.
The limiters for speed on a nuclear air crafter carrier are cavitation of the propellers and the strength of the tip of the boat which is flattened for stability. The force needed to go faster through fluid and with a larger vessel increase exponentially, not linearly.
The problem with cavitation is countered by having variable pitch propellers, and hull strength is not an issue considering that an aircraft carriers hull is 4in thick. Hull speed increases when the length of the water plane of a vessel increases, it doesn't decrease. Also there isn't too much of a worry about the energy required to spin the propellers when you have two nuclear powerplants onboard
I was actually ON the Nimitz for almost three years. I am gonna say the speed rating listed was max TURNING speeds. Sea trials was a blast layin that ole girl over. I can attest that yes the Nimitz could go anywhere it wanted as long as there was enough water to float her. We were in port when Hurricane Diana came up the east coast. WORST place to be in a ship so we put out to sea. While out there someone got the bright idea to collect weather data so we aimed her into the hurricane... launched air craft out side go into the eye, launch more air craft... go back out recover the ones outside then go back into the eye for the rest. Waves were braking over the bow and that big ole beast barely moved.
@@shirothehero0609 Yes it was. . That and many many more surprising things that happened when I was onboard.

We could figure out how fast they actually go tho right? Like when a war breaks out the aircraft carrier will be sent to that area of the world seems like you could work the math out early.
That's 35 knots, not mph, so a carrier is a little faster than you think....actually they are a lot faster than people think. I've seen one go speeding off so fast that it left us on the escorting destroyers in the dust, even as we kicked it up to our own classified top speed. Good build you did, here.
Yeah, the "official speeds" are always an understatement in the military world. I've been driving on a highway next to a military base where they do tank training, and had an abram's pass me while I was driving well over it's official top speed. I've heard the carriers are the fastest ship in their battle groups, on purpose, because they wanted them able to GTFO if necessary. Makes sense really, they're, well, awfully expensive lol
@@jttech44it’s just physics… maximum hull speed in knots is equal to 1.34x square root of the length of the hull at the waterline in feet. So for a standard displacement hull (non-planing) a longer ship will always be faster as long as sufficient power is available.
According to @stevenmarlowe9767 calculations a modern aircraft carrier can go 43.2 knots(provided it has enough power) a modern destroyer can go 30.2 knots(same stipulation as above) all of this is based off of his given formula and googled data on the ships. All of this is also taken with a grain of salt as the military could have top secret ways of making ships faster.
Mph != knots. Unofficial reports from other navies have Nimitz class ships going ~42kn (48,3mph, 77,8kmh). At that speed your model carrier would probably become airborne itself.
Another note on this, that's *fast* for a modern warship. I know frigates and destroyers that only go 35 knots. They're some of the fastest warships around and they're huge
I love these videos! I also enjoy hull modeling and making crazy-wave RC boat videos, and learned that scale speed actually scales by the square root of length scale, rather than length scale itself. So for 1/200 scale, multiply the speed by about 14. Still really fast: 37 model mph scales to over 500 full scale mph - jumbo jet speed! Time also scales this way - if you want a "real" looking video, slow it to 1/14 speed. This is based on Froude number - it can be used to scale other hull parameters too.
I heard a navy guy telling a story about an actual speed test they did with the 4 power plant a/c carrier we have; built as a testbed. It typically uses only 1, and 2 if it's in a bit of a hurry. They used 4 during a proving test and it hydroplaned.
Some advice , the nose design on these aircraft carriers is meant to dive under waves and cruise smooth and stable in giant waves , not a surfer , a smoother , longer pointed nose with a horizontal flat belly will surprisingly make it lift higher and more mass on both ends ( torsional inertia ) will stop the pitch bouncing up and down .
DO NOT POST THE NIMITZ CLASS OWNER'S MANUAL PDF HERE - POST IT TO THE WARTHUNDER FORUMS LIKE EVERYONE ELSE DOES (hey FBI, this is called a joke. No one sane wants idiots leaking our stuff.)
Needless to say you might already know this. That hull, really wants to be submerged and not half-exposed like speed boats. Which goes to show how in engineering, everything is a compromise. Large hulls are optimized to allow water to flow around them with out many losses. They are efficient at low speeds and awful at high speeds. Speed hulls are optimized to have the least contact with water, they want to be above water. They are efficient at high speeds but awful at low speeds.
Daniel, I served on the Nimitz. The claimed ~35 knots is not the max speed, that is the average speed of that carrier. The Navy will not officially release the actual speed as national security. Just saying, we left San Diego around noon ,were told to heavy tie-down alll birds on deck, and we crossed made Japan port in under 24hrs. I had a bird on deck with an avionics issue that required us to run the GPS and nav. The carrier was creating a wake over 60ft tall, and our GPS was reporting almost double the top speed you claimed. We crossed the Pacific Ocean in a day....
I have heard one or more sailors report 60 knots, (70 mph). That's 1680 miles per day. Hawaii in one day seems nearly doable, but Japan in one day seems outlandish.
I think this is only possible if they are also massively under-reporting the shaft power of their propulsion. Referencing data like top speeds reported by cruise liners (e.g. 30kts at 80MW for the Queen Mary 2), and using a conservative Cube law P = v^3, it would take a massive 650MW shaft power to reach a speed of 60kts. It's still within the possibility of the nuclear powerplants (2 reactors, 550MW each according to wiki), but to dissipate that much heat on a ship is insane (taking a few tons of sea water per second?).

Turns out water doesn't scale linearly. Take a look at something called Dynamic Similitude Speed. You need to use the square root of the scale to determine the scale speed. You also use the square root of the scale to to slow down time when looking at the film of it. You actually reached a scale equivalent of 525.8 mph. Also, there is a scale combat club in the Seattle area that builds functional RC battleships, which sounds right up your alley. It's an engineering challenge to build functional cannons and the damage control to make it survive the fury of battle. Much more fun than basic, boring scale modeling.
I am a retired US submarine sonar tech and we would hunt these for sport 😂honestly really cool model. Lots of speculation about speeds in the comments, remember that it's always measured in knots not mph and I know all the real answers but I can't tell you 😅
So I heard the actual top speed of USA nuclear aircraft is a “secret” but after 9/11 there was an aircraft carrier at port somewhere on the other side of the Atlantic Ocean. It traveled across the ocean and came to port somewhere on the east coast USA. Someone calculated that it had to be doing an average speed of 70mph.. it wasn’t doing 70 the entire time so it can probably actually go even faster. Am I the only person who has heard this?
You can work out the maximum theoretical speed of a displacement hull from it's waterline length. The full size aircraft carrier cannot go any faster because the back end will 'squat' & the front end try to climb it's bow wave.
@sprolyborn2554 with an aircraft carrier weighing in at over a thousand tons I suspect that the excess heat generated by a power source capable of making it plane would melt through the bottom of the Hull!
@@pcka12 again, eventually it could ride over its own bow wave. Of course the power needed isn't anything we have but it is still possible. I've seen sailboat hulls plane with a big enough diesel crammed in the bilge.
This carrier is fantastic! Whole lotta fun watching it go! I was on the Forrestal CV-59 in the North Sea. We were at flight ops with 74Kts of wind over the bow and once in a while a wave would break onto the flight deck from port and Starboard aft. Our aircraft were getting salt water on them and we had to work long hours with water displacement compound etc for corrosion control.
Are you sure about that? Some research seems to suggest that the fastest dont go any faster then about 33.6 knots or 38.66mph or 62.24kmph. Some sources suggest 38 knots... but those are not official numbers. Anyhow... that is super fast for a ship.
@@wiredforstereo Yeah sure, but "a hell of a lot faster" is kinda defying the laws of physics if you ask me. The amount of energy required goes up exponentially the faster you go.
Love your tenacity. Good effort. I was in the Royal Navy and whilst on a British frigate I supported a US Presidential class carrier. Seeing it do over 35 knots was awe inspiring, about a quarter square mile of sea erupted outta the stern when it accelerated to flying stations.
if you scale realistically, you're not counting the wind resistance, the support of the metals, and everything else which may be different weight and forces, it's not as easy as that to "scale" things higher or lower, a lot of plane prototypes are successful but not at the full scale edit: but otherwise, good piece of work
It's such a joy to see your inner kid come out while you're playing with your carrier! Yep! Your carrier is faster than the published speed of a nuclear carrier. I've been told (unofficially over beers) the actual speed is up around 45 to 50 knots.
A Navy chopper pilot, once told me, in the 60s, he was lowering a pilot on to the deck, he looked to see what the chopper speed was and said it was 65 knots. That is the relative speed needed to keep up with the carrier to place the pilot onboard safely.
I went on a tiger cruise when my buddy was in the navy on the USS Carl Vinson. We did a drag race with the rest of the fleet. It accelerated the slowest but had a higher top speed than the rest of the fleet. It eventually overtook the other ships. Definitely very very powerful. It was a hell of an experience that trip
About 10 years ago, I took a cheap RC boat from Walmart and added the controls and motor from my wrecked Losi RC car. It had so much power. It would spin the boat clockwise when it accelerated. I wound up adding on a hull plane to the right hand rear corner to counteract the torque. Then I put three battery packs in the nose of the boat to keep it from jumping out of the water. Eventually, I wound up having to shave my prop down to 5/8 of the size it came. Eventually, when I got it all straightened out the thing would do an Olympic size swimming pool in 2 1/2 seconds. It blew out four different driveshafts to the point where it sits on its stand on the shelf because it was so much fun. There’s a few eventually in there because it took about two weeks of an hour a day messing with it to get the thing to work. You want more power? It’s gonna take a little tooling.
The length of a displacement hull has a theoretical speed limit that can be calculated. The longer the better. This applies to full sized ships. The model became a planing hull.
There is no way that is 200 times smaller, if from bottom to top is around 1 foot, that would mean that the carriers are only 200 feet tall which is not true, they are much larger.
I Served 4 Years Aboard The USS Dwight D. Eisenhower (CVN-69), In Air Dept/V-1 Div, As An ABH3 From 1980 - 1984. When We Did High Speed Maneuvers, Although Top Speed Is Classified, We Could Tell By The Water Passing Under Us That We Were Going Faster Than 35 Mph! ⚓
Found a propeler that is called PVBD that has a secund propeler where the propeler vortex wold be created. Instead of a cone at the end, it has a built in propeler with channels from the propeler to lead the vortex water through a propeler case to brake up the vortex. Some submarines are using it to lower the sound and get more efficient pawer use at lower engen speed.
Careful now, the safety of the world's oceans is depending on you! The slo-mo shots right at the start were pretty realistic looking, but the shots of the smoke pouring out of the hull took the cake for realism!
Fun video. Do you know what Reynolds number is? Look it up. That is how you must scale speed in a fluid, not by the scale size of the boat. Still a fun thing to watch.
The other suggestion would be to narrow the motor boom mounts so that the props can grab more water. Make them more like an outboard motor where the prop mounts.
as a civillian i had the extremely fortunate opportunity to go on a cruise aboard the USS HUE CITY in july of 2013. it took us 3 days to cruise from virginia to jacksonville. so i absolutely believe these ships only go 35.
You might have added some fun facts about these incredible, floating cities that can transport 6000 people (and equipment) at 35 knots sustained for 90 days driven by two reactors that need refueling once every 25 years. These machines truly are the marvels and culmination of our civilization's advance. I understood that a Ford Class Aircraft carrier can travel 35 knots or 40.2 mph. Amazing tech skills here. You are taking "breaking some eggs" and "what-if" engineering to the next level. It would have been interesting to approximate the weight of the model as a representation of real-life scaled-down.
Just FYI when lipo cells drop below around 3 volts internal cell damage begins to occur. There's no way to test for this damage and no way to fix it. It can result in rapid catastrophic failure of the battery at any time after that damage occurs without warning.
The USS Kitty Hawk hit an average of 42 knots (48.33 mph) and the USS Enterprise "allegedly" hit 50 knots (57.53 mph). With improved power plants and technology, you can be assured that the 35 mph number is way off the real numbers.

DO NOT POST THE NIMITZ CLASS OWNER'S MANUAL PDF HERE - POST IT TO THE WARTHUNDER FORUMS LIKE EVERYONE ELSE DOES

people who comment without watching the whole video cant even get 4 seconds in these days lmao
@@LuckyLeprechaun100 wtf r u saying lol why would he wait til finishing to comment about something relevant at 4 seconds in

You need to have Ward Carroll as guest commentator. "Deep Intel on rapid deployment modules for the Ford class carriers"
21:16 "But that is classified information" Random warthunder player : "Not anymore!"
Needless to say you might already know this.
That hull, really wants to be submerged and not half-exposed like speed boats. Which goes to show how in engineering, everything is a compromise.
Large hulls are optimized to allow water to flow around them with out many losses. They are efficient at low speeds and awful at high speeds.
Speed hulls are optimized to have the least contact with water, they want to be above water. They are efficient at high speeds but awful at low speeds.
I read the first part of this as it needs to be turned into a submarine
0:53 “hey baby can we just watch big ships crashing through waves…. “
Daniel, I served on the Nimitz. The claimed ~35 knots is not the max speed, that is the average speed of that carrier. The Navy will not officially release the actual speed as national security. Just saying, we left San Diego around noon ,were told to heavy tie-down alll birds on deck, and we crossed made Japan port in under 24hrs. I had a bird on deck with an avionics issue that required us to run the GPS and nav. The carrier was creating a wake over 60ft tall, and our GPS was reporting almost double the top speed you claimed. We crossed the Pacific Ocean in a day....
The carrier is always the fastest ship, the true speed is classified on purpose.
I have heard one or more sailors report 60 knots, (70 mph). That's 1680 miles per day.
Hawaii in one day seems nearly doable, but Japan in one day seems outlandish.
I think this is only possible if they are also massively under-reporting the shaft power of their propulsion. Referencing data like top speeds reported by cruise liners (e.g. 30kts at 80MW for the Queen Mary 2), and using a conservative Cube law P = v^3, it would take a massive 650MW shaft power to reach a speed of 60kts. It's still within the possibility of the nuclear powerplants (2 reactors, 550MW each according to wiki), but to dissipate that much heat on a ship is insane (taking a few tons of sea water per second?).
@@chakflying1Considering that this is the US navy we’re talking about I’m sure they’ve found a way to do it
@@chakflying1well the (public) generation capacity is like 1.5GW
"The 1930 Robertson Waterplane ground-effect vehicle powered by an outboard motor". There are pictures and videos, but I don't think I can post a pic in the comments. I saw this the other day and immediately thought this might be something you'd build or at least be interested in knowing existed, if you don't already. In other news... it's getting to be grass cutting season. I hope you are working on your next autonomous mower contraption. I'm a long time subscriber to the channel and grateful for your willingness to share your talents with the world. Keep up the great work! - Stanford
Turns out water doesn't scale linearly. Take a look at something called Dynamic Similitude Speed. You need to use the square root of the scale to determine the scale speed. You also use the square root of the scale to to slow down time when looking at the film of it. You actually reached a scale equivalent of 525.8 mph.
Also, there is a scale combat club in the Seattle area that builds functional RC battleships, which sounds right up your alley. It's an engineering challenge to build functional cannons and the damage control to make it survive the fury of battle. Much more fun than basic, boring scale modeling.
An interesting study of ESC's and battery power.
I am a retired US submarine sonar tech and we would hunt these for sport 😂honestly really cool model. Lots of speculation about speeds in the comments, remember that it's always measured in knots not mph and I know all the real answers but I can't tell you 😅
When I was in the Navy we were told an aircraft carrier could do 60+ MPH. The + ment anything above 60 was classified.
So I heard the actual top speed of USA nuclear aircraft is a “secret” but after 9/11 there was an aircraft carrier at port somewhere on the other side of the Atlantic Ocean. It traveled across the ocean and came to port somewhere on the east coast USA. Someone calculated that it had to be doing an average speed of 70mph.. it wasn’t doing 70 the entire time so it can probably actually go even faster. Am I the only person who has heard this?
I'm pretty sure this whole thing ends with a ground effect flying aircraft carrier
You can work out the maximum theoretical speed of a displacement hull from it's waterline length.
The full size aircraft carrier cannot go any faster because the back end will 'squat' & the front end try to climb it's bow wave.
this is true until you start reaching into the truly ludicrous when it comes to power. anything can plane with enough power.
@sprolyborn2554 with an aircraft carrier weighing in at over a thousand tons I suspect that the excess heat generated by a power source capable of making it plane would melt through the bottom of the Hull!
@@pcka12 well yeah. The point still stands. With enough power, anything can plane.
@@sprolyborn2554 the physics of the junction between two fluids one practically incompressible & the other not!
@@pcka12 again, eventually it could ride over its own bow wave. Of course the power needed isn't anything we have but it is still possible. I've seen sailboat hulls plane with a big enough diesel crammed in the bilge.
fun fact, if scaled, the real ship would be going around 518 mph.
or 833 km/h for anyone outside the usa
Dude you are killing it with these videos. We need more creators like you. Would have been cool to do trim tabs controlled by the pixhawk.
Hydrofoil Aircraft carrier when? :D Awesome video!
This carrier is fantastic! Whole lotta fun watching it go!
I was on the Forrestal CV-59 in the North Sea. We were at flight ops with 74Kts of wind over the bow and once in a while a wave would break onto the flight deck from port and Starboard aft. Our aircraft were getting salt water on them and we had to work long hours with water displacement compound etc for corrosion control.
next week: building a full scale RC US Navy
How about a fleet tied together using ardupilot? Single waypoint paths and they all stay in formation
Maybe a full scale chinese navy
@@spammerscammer do both and have em duke it out
I'm so here for this. Were you hinting from the out of water shots that an aircraft carrier ground-effect plane is next? Hahahahaha!
I'm not sure where you got your full-scale carrier speed numbers from, but they can go a hell of a lot faster than 35 knots when needed.
Source: Trust me, bro.
Are you sure about that? Some research seems to suggest that the fastest dont go any faster then about 33.6 knots or 38.66mph or 62.24kmph. Some sources suggest 38 knots... but those are not official numbers.
Anyhow... that is super fast for a ship.
@notahotshot There are lot of people who have served on carriers who aren't allowed to tell you exactly how fast it goes.
@@wiredforstereo Yeah sure, but "a hell of a lot faster" is kinda defying the laws of physics if you ask me. The amount of energy required goes up exponentially the faster you go.
They use a LOT of fuel in the US military
An aircraft carrier getting up on plane, what a time to be alive.
love the cookies in the tuppaware container at 13:46
Love your tenacity. Good effort. I was in the Royal Navy and whilst on a British frigate I supported a US Presidential class carrier. Seeing it do over 35 knots was awe inspiring, about a quarter square mile of sea erupted outta the stern when it accelerated to flying stations.
if you scale realistically, you're not counting the wind resistance, the support of the metals, and everything else which may be different weight and forces, it's not as easy as that to "scale" things higher or lower, a lot of plane prototypes are successful but not at the full scale
edit: but otherwise, good piece of work
It's such a joy to see your inner kid come out while you're playing with your carrier!
Yep! Your carrier is faster than the published speed of a nuclear carrier. I've been told (unofficially over beers) the actual speed is up around 45 to 50 knots.
i was stationed on three aircraft carriers and can attest that our cruising speed is 35mph, but our full speed is well above that.
A Navy chopper pilot, once told me, in the 60s, he was lowering a pilot on to the deck, he looked to see what the chopper speed was and said it was 65 knots.
That is the relative speed needed to keep up with the carrier to place the pilot onboard safely.
You know a project is getting fun when you're thinking about the optimal CG of an aircraft carrier.
I went on a tiger cruise when my buddy was in the navy on the USS Carl Vinson. We did a drag race with the rest of the fleet. It accelerated the slowest but had a higher top speed than the rest of the fleet. It eventually overtook the other ships. Definitely very very powerful. It was a hell of an experience that trip
*Jets taking off* WOOOO HERE WE GO!
*Jets landing* Hey wait up!
Thank you, Daniel, for showing all of the building of the boat parts in the video. I really enjoyed it! I definitely noticed, and I appreciate it! 😊
About 10 years ago, I took a cheap RC boat from Walmart and added the controls and motor from my wrecked Losi RC car. It had so much power. It would spin the boat clockwise when it accelerated. I wound up adding on a hull plane to the right hand rear corner to counteract the torque. Then I put three battery packs in the nose of the boat to keep it from jumping out of the water. Eventually, I wound up having to shave my prop down to 5/8 of the size it came. Eventually, when I got it all straightened out the thing would do an Olympic size swimming pool in 2 1/2 seconds. It blew out four different driveshafts to the point where it sits on its stand on the shelf because it was so much fun. There’s a few eventually in there because it took about two weeks of an hour a day messing with it to get the thing to work. You want more power? It’s gonna take a little tooling.
Haha! Loved the video guys. Shoot me a PM love to talk with you guys. Fun seeing you do this to one of our scale models haha.
I checked, am impressed with the selection. Looks like I might be able to try out an idea.
The comments provide on great vids. Happy money making.
You should make the drive pontoons look like tug boats, re-supply ships, frigate or whatever is close to scale.
10 horsepowers would be 2000 to scale, right? That doesn’t sound too much.
lmao, it's pretty funny to imagine an aircraft carrier actually going that fast
The length of a displacement hull has a theoretical speed limit that can be calculated.
The longer the better. This applies to full sized ships. The model became a planing hull.
The footage with the music at the end - best part of the whole video !! But great video, looked a lot of fun to make!
Every time the hatch opens and smoke pours out, I laugh out loud! I'm a child at heart.
2: 56. Holy What?
4:52 I will never forgive RC test flight for butchering the Gripen =(
Next step? Powering from a scale nuclear reactor?
Cool project!
Sad to see that missing knowledge is loved and honored by many people.
3:54 he thought we wouldn't notice
I'm now adding seeing a planing super-carrier to my bingo card for the next 5 years.
There is no way that is 200 times smaller, if from bottom to top is around 1 foot, that would mean that the carriers are only 200 feet tall which is not true, they are much larger.
this feels so out of character of you. I love it!
I Served 4 Years Aboard The USS Dwight D. Eisenhower (CVN-69), In Air Dept/V-1 Div, As An ABH3 From 1980 - 1984. When We Did High Speed Maneuvers, Although Top Speed Is Classified, We Could Tell By The Water Passing Under Us That We Were Going Faster Than 35 Mph! ⚓
You can add a tow line to the drone with magnets for the future meltdowns!
Found a propeler that is called PVBD that has a secund propeler where the propeler vortex wold be created. Instead of a cone at the end, it has a built in propeler with channels from the propeler to lead the vortex water through a propeler case to brake up the vortex. Some submarines are using it to lower the sound and get more efficient pawer use at lower engen speed.
just watched bridge over the river kwai the other night, and the sheer speed of this carrier is roughly proportional to nicholson’s insanity
The way that was riding, I am surprised you didn't go for turning it into a Hydrofoil! A hydrofoil Nimitz would be wild!
Videoing the ship in slow mo is how they assess the effects of the sea on scale models when developing real vessels in test tanks.
Damn Dude, thats staggeringly fast considering its SIZE.
Good JOB!!
oh yea
suiii
Careful now, the safety of the world's oceans is depending on you! The slo-mo shots right at the start were pretty realistic looking, but the shots of the smoke pouring out of the hull took the cake for realism!
0:30 The way you handle the microphone 😂🤣👍🏻🤝🏻🇳🇱
The duck cracked me up. Thanks :)
Fun video. Do you know what Reynolds number is? Look it up. That is how you must scale speed in a fluid, not by the scale size of the boat. Still a fun thing to watch.
In physical hydraulic modelling, the Froude number is used for scaling. I believe it is the same for ship building.
But they used neither; jusst scaled speed by length, which is totally wrong.
When they discover oil in your country and suddenly you qualify for same-day delivery of freedom and democracy
The other suggestion would be to narrow the motor boom mounts so that the props can grab more water. Make them more like an outboard motor where the prop mounts.
as a civillian i had the extremely fortunate opportunity to go on a cruise aboard the USS HUE CITY in july of 2013. it took us 3 days to cruise from virginia to jacksonville. so i absolutely believe these ships only go 35.
if they're doing this with civilians they probablly wouldn't go full speed/noticiblly higher than public knowlage
This guys videos are just the best.
You might have added some fun facts about these incredible, floating cities that can transport 6000 people (and equipment) at 35 knots sustained for 90 days driven by two reactors that need refueling once every 25 years.
These machines truly are the marvels and culmination of our civilization's advance.
I understood that a Ford Class Aircraft carrier can travel 35 knots or 40.2 mph. Amazing tech skills here.
You are taking "breaking some eggs" and "what-if" engineering to the next level.
It would have been interesting to approximate the weight of the model as a representation of real-life scaled-down.
that duck was so chill when you picked it up
Just FYI when lipo cells drop below around 3 volts internal cell damage begins to occur. There's no way to test for this damage and no way to fix it. It can result in rapid catastrophic failure of the battery at any time after that damage occurs without warning.
Uh hmmm...
Is it a power to weight ratio that allows a scale model to go faster?
I was on that carrier (it was the kittyhawk btw) when that clip of a carrier crashing through the waves was filmed. It was pretty insane.
I really like the front on camera style of narration
A city with an airport that can go 35mph or so for 25 years without stopping sounds pretty impressive.
Dude has turned Aircraft into a Rocket Ship. I think Pentagon will call you next week.
I was on the Kitty Hawk cv63. One time we pulled 37 knots. The captain was so proud he told us on the ships horn. Conventional too
The USS Kitty Hawk hit an average of 42 knots (48.33 mph) and the USS Enterprise "allegedly" hit 50 knots (57.53 mph). With improved power plants and technology, you can be assured that the 35 mph number is way off the real numbers.
Get back to me when you can launch RC Jets and fly them off that RC Aircraft Carrier.
