If it doesn't look like it should fly, and it flies, I auromatically like it
Thanks Joel!
Hello Joel!
Is bee
auromatic?
@@beaconblaster33 It means they like the smell of it.
Helicopter? Right! More like rocket powered rotating knife
I love it !
Throw some tomatoes at it
Maybe I should try making one from an actual sword next 😉
@@Project-Air maybe a rocket powered boomerang too!
lol awesome
David Windestal did the rocket knife some years back. It was (quite literally) a knife attached vertically to a rocket powered sled on a rail, with something at the other end to take the impact.
That was really cool, if I just saw a picture of that I never would have thought it could fly. I want some of those motors now too!
Hey Kevin reply to this video im a big fan of you science stuff
Please reply i beg you:)
Yeah those motors are super cool man! Burn times of something like 10-18 seconds depending on the size. 😊😊
@@Project-Air but anyways that is so creative thumbs up to your work and i also liked the video
How about I reply instead to tell you how embarrassing your comment is?
Please don't reply to me, I am begging you
totally dude. 100% true dude
When I was a kid (about 65 years go) I bought a Jetex-powered helicopter.
Jetex was a small solid fuel rocket motor, about 1 inch long.
The helicopter had two rocket engines at the ends of the rotor, like your first design.
I too encountered the problem of sometimes only one engine firing, which shook the copter violently.
When it worked properly it flew quite well.
Ah the 60s. A great decade where children could get their hands on solid rocket motors
"No control whatsoever"... sounds like a plan.
You and @Integza are definitely spending too much time together🤣
lol dude pro comment
2:52 There is something really satisfying about seeing it start to rotate with nothing but the fuse burning.
50 years ago Standard Fireworks used to make those out of a small strip of cardboard and a small rocket motor.
Designed to be used in the standard (no pun intended) terraced house back garden. They amused a generation of fathers and terrified a generation of small children as the watching family would have no idea which way the highly dangerous toy would fly off. It would elevate to cry’s of ooh’s and aah’s and the occasional “look out” as it would hit buildings on its way up.
If only we had UA-cam when we were young….. and CAD printers may have been handy too!
Suggestion: A rocket powered car. But not in the way you'd expect. A gear gets spun by rockets (like the mono-copter) and that connects to the actual wheels moving the car forward. It's an idea of the wacky type
Like the turbo axle
I was thinking the exact same thing. It might be hard to do with just one motor though
pretty sure thats just a turbine engine
There's now a downloadable project kit for this rocket helicopter! Check it out ---- store.projectair.co.uk/products/rocket-helicopter
Where did you get the rockets from?
Because I don’t see it in the description
@@polarcraft9095 I've added it now :)
Next time build a proper fpv plane with head tracking and a realistic cockpit
are you done with the submarine project?
So I have some potential for improvement here.... possibly. It sounds like, purely from the sound, the helicopters are rather quickly reaching their maximum rotational speed and then staying there for a while. From my knowledge of rockets, the thrust they produce is basically a function of the exhaust gas speed vs the forward speed of the rocket, especially when you're in an atmosphere. So my thought here is that possibly the rockets, with the arm length and rotational speed, are reaching a linear speed that's basically equivalent to their max thrust minus however much for drag forces. So hypothetically you could get it to rotate even faster by putting the rocket closer to the center of mass of the unicopter. You could probably pull that off by having the arm extend past the rocket's position and act as a counterweight to the main wing, and possibly even improve the lift by making that counterweight a much smaller wing.
The other alternative is that the linear speed issue is negligible compared to the sheer drag of the whole system, at which point I wonder if you could get better performance with a larger, slower, more efficient wing design. Or even a 2-stage system. 2-stage rocket unicopter would be amazing.
Rocket powered submarine.
Yes, you heard me.
Just wanted to say thanks for all these awesome videos and to keep up the rocket propelled projects
couldn't agree more. totally accurate
This rocket-copter is sick! Could you do a rocket powered dragster in a future vid?
Nice idea!
I'd watch that lol
There have been so many of those done. It would be nice to see someone take it seriously and science it out. Good idea
agreed. totally right
Did this when I was 12 lol
Love ur vids. They are really good and all of your creations are awesome. Keep up the excellent work.
Thanks!
Yeahh!! That's my video 0:30
Very interesting project! I see the resemble of maple seeds falling. I love to watch them float, parachute, tumble, spin and glide to the ground as you explore the aerodynamics of seeds. Awesome project!
Thanks so much again for allowing me to use it, Arleth! Shame I couldn't find any seeds like this in my garden, but you saved the day! Glad you enjoyed my video. :)
My pleasure 🍁🚁@@Project-Air
I like the helicopter projects not many are done but they are fun to watch.
Yeah they’re quite different!
I love these little projects! Nice design!
Thanks! Yes me too. They’re fun
@@Project-Air Maybe a little rocket powered boat next?
We have fireworks in America like this but they also explode. When I was a kid we called them buzz-bombs.
Monocopters! There have been some pretty insane large ones in the high power rocketry world over the years.
When I was a kid my father gave us puddle jumpers. They were a airplane propeller glued to a stick in the middle of the hole. One swipe of your hands to spin it and up it went!!! Tons of fun for hours.
Maybe you could somehow incorporate a stick of some sorts for stability. ❤️the channel
This is awesome . Thanks for MORE ROCKETS
Die cast rocket car, fastest die cast car possible
This is basically what the bee firework is right? Altough that is better because it has less rotational inertia. Still pretty cool though.
Yes I guess so!
Did this when I was a kid in the 1970s. No 3D printer, all built by hand. I got the helicopter ideas from spinning fire works. Made all kinds of things using wood and sheet metal and rocket motors. History repeats itself.
I'll tell you something mate first of all well done on all your projects because I absolutely love them..your amazing my friend keep doing what your doing..after all at least your motivated to the core...take care pal 👍
The weight of the engine changes as the fuel burns. I think a multi-stage rocket plane with these motors would be fun to watch.
i believe they make fireworks like this with a side exit exhaust. Basically a modified ground bloom that takes off into the sky.
I thought of these, too! I never quite understood how they work, though. They don't have any obvious lifting surfaces. 🤔
@@unvergebeneid As far as I can tell, they are quite common in Germany. Afaik you can even get them year round.
You did what I used to wonder about doing. Especially rocket motors along the sides of a plastic propeller.
I wanna see a rocket-powered craft that launches into the air like a rocket, but then safely lands using pop-out propellers to spin. Awesome video!
I had a model rocket as a kid that did exactly this. It was very cool until i broke the fold out rotors
If you can lock it in place temporarily(fraction of a second) until you can light both motors, seems like a symmetrical 2 motor rotorcraft design could fly in a more balanced way, and go a long distance
That's freakin cool! If these were scaled up, had a dome in the middle where a pilot would sit, it'll be very steampunk 😁
Is steampunk a slang term for retarded?
Just looks like a butter knife flying through the air, really amazing concept.
I really appreciate the videos you make. Wonderful to share interest of aviation and rocketry. 👍
Barely pitch the engine-mount angle, as opposed to now relying entirely on the engine solely to rotate and the blade's ability to lift: separately, the prop-blade, perhaps a single triangular wide-tip fan-vane would better balance the thrust into lift.
As the propellant burns the center of gravity/rotation will change substantially. I wonder how much the RPM changes. Perhaps making it stretch out as the RPM increases can compensate for this?
Two opposite rockets would solve that problem far easier. Just get these darn things burning BOTH. Reliable ignition, maybe?
@@voornaam3191 that defeats the purpose and benefits of a one engine one blade device
Just discovered your channel tonight. I must say there are some very imaginative projects on here. Too bad that you're on the other side of the pond because I would love to watch in person some day. Best of luck, keep up the good work and above all have a happy and HEALTHY New Year.
The seed works so well because of the heavy weight ball that becomes the centre of rotation it helps stop the side to side pull of the mono blade so if you can replicate that a bit better on yours it might go straight up just an idea
i would love to see a rocket powered and steered plane
I'll deffo be doing more rocket planes in 2022!
i thought the thumbnail was clickbait lmao
Haha glad it delivered
Great work, those look fun
Brilliant video .... thank you for making me smile and inspiring me to fun stuff with rockets... My wife just shakes her head and calls me names .... So I put that down to success...
How about one of them folding rocket gliders that snap open at the highest point of their trajectory?
You can't launch those with low thrust long burn motors like this. Those are for shorter burn higher thrust rocket motors. Otherwise it is more efficient to use the wings for lift in the climb. Plus, these have no secondary function like delay or ejection charges to activate things.
I would like to see a retro rocket parachute. This was attempted during WW2 with little success, but more recently it was used on the Mars mission very successfully.
This will be a challenge!
Can you please describe what a "retro rocket parachute" IS? Please please please give more information, for it does not ring a Bell helicopter, here.
@@voornaam3191 this device provides a braking effect on a free-falling object using rockets to provide thrust. Imagine you dropped a pallet of goods from a transport plane at low(ish) altitude (stabilised by a small drogue chute) as it approaches the ground at high speed, altitude sensors detect this and trigger rockets which quickly slow the vertical motion allowing a soft landing. Experiments were done during WW2 by the British, but the available sensors in 1943 made it unreliable and the project was abandoned. With modern sensors and computer control, it should be a possible, but challenging project.
Well done enjoyed this immensely
The civilatory project is alive. Men like you are important. Thx!
Possible idea: Use the expanding gasses of the rocket engine to drive a steam engine. The idea is quite interesting and the modern vs old fashioned tech contrast is also nice.
How bout a massive rocket powered water wheel? Have the thrust hit the wheel buckets instead of water. I could see that spinning fast enough to open a portal to the upside down.
3D printers really are amazing. I have literally thousands of hours on my original ender three and I have yet to have a single mechanical failure that wasn't my fault.
Your enthusiastic face makes me totally believe that having "no control whatsoever" is the most desirable feature on earth
Wow u did very good job.it kinda like the monocopter and ...
I loved it!! Good job!!!😁
The first thing I was thinking was actually "Yes you can, they make cheap fireworks that are literally cardboard, rocket-powered helicopters" but still, cool footage and cool project!
How did I miss this vid. This is epically awesome
That is pretty cool! I have an idea for the next video, maybe you can make an RC plane that is powered from that helicopter
Long burn, multi stage rocket planes would be cool! Like, one high powered slow burn to take you up, then some longer burning, lower powered ones to keep you aloft when you need more speed/altitude!
Keep up the good work dude!
I agree! I’d love to build some like that ☺️☺️
The spectator cows at 6:28 are the absolute best! 😃
Awesome video!
I always wanted to make an RC boomerang. This is a good start.
Outstanding shipmate. Press on. USS Kitty Hawk CV-63. Jan 1980 to July 1983.
Awesome. Yes build more new designs. Please
First video I’ve watched from you. Subscribed within ten seconds. Gunna watch all day long lol
I loved that video James good job
Ah it's great to see quality Goblin trap making. Well done good sir many adventures will fall to these flying lobotomy devices.
Lockheed Martin did this about 15 years ago, there's was about the size of what you did. It was classified for a long time and then the project was scuttled. The engine was "grown' on a copper chip and I was a VERY small turbine engine. It had a camera on it that was able to compile a 3D scan of a battlefield, or even a building. They also figured out how to equip it with a small explosive charge that would have been lethal. It was able to be steered using control surfaces and the engine was able to vary it's output rapidly to change course, hover and fly.
Really cool tech, I know the guy that designed it and I did some of the machining on it myself.
And I like how you are always innovating keep it up
Nice. Nothing could possibly go wrong doing this! I wonder if the stability and overall performance would be enhanced by adding a fly bar.
described in one word epiccc !
Super idea for making this
That moral support from Cow spectators was very motivating
Cool designs man
Thanks for bumbing that into my head while I was peacefully coming back home with groceries
You just reinvented a $3 firework that’s been around for ages…but you did it with style.
That’s amazing
Great stuff
Genius bro as soon as I saw it fly in the first few seconds I immediately wanted to know how the heck you did it.
I love how in the beginning his reasoning is “ I know it’s dangerous and potentially lethal, but hey.. views!” Fair enough my friend, you earned a new sub 👍
Tip jets are amazing ❤️
A rocket powered boat seems like the next thing to build, James :)
Reminds me of the jumping jack spinner fireworks 😎🤙
Interesting to see that even a lit fuse provides some measure of thrust - never expected that although it makes sense now
Now that’s fun!!!
This video is really well made :D
If you revisit this, the optimum is with the rocket thrust vector angled somewhat downwards. Similar to how jets in cruise are a bit nose up, the best use of thrust and lift is mostly lift but with some thrust.
Great vid!!! you should make small missiles that you can launch from an RC aircraft of some sort!!
the dual motor version might have worked if you locked the prop until both motors fired up and then released the lock. a simple dowel or steel pin might do.
This is a great idea. The current through the igniters could probably be monitored by a microcontroller for an automatic release.
Please make even more monocopter videos! Love it
the single blade design is cool because when the motor burns and it autorotates back it resembles those seeds of a maple tree that are very similar and autorotate down like that.
Dude you totally HAVE to build a giant one!!! Like NOW!!!
That's pretty cool
That's cool!
For electronic ignition wire from a vape does the trick perfectly. 2s/3s battery will light off but you would want more of a timer as 2 seconds lights it but 6 seconds burns it. For rotational mass issue you should look further at the angle of attack
this could be a really cool firework
Interesting concept of a tip jet helicopter.
Rocket powered Maple seed pod...Whoo hoo!
This is how you make a helicopter in a game with no air physics, put thrusters on it and pretend it's a regular heli.
Now there’s a ballistic knife if ever I saw one ;-) GG!
this is a technical revolution !
Bro I buy this firework every year it has a nail in the middle to nail it to something it spins fast
"Check out this 1950's technology!" IIRC, Hiller developed a bunch of small, one man helicopters that used rocket or jet thrusters at the rotor tips.
I wonder if you could get two motors to more reliably ignite if you used a hold-down clamp that released like 1/4 second after ignition. That way the first motor to start doesn't rip the starting equipment off the second motor before it ignites.
You have made a flying knife, this is mad
i love planes so i found you. Now you are my favorite youtuber ;)
Cool, but wildly unpredictable! Maybe some center mass would help. Still super cool in a duck-and-cover kind of way!
i love playing with thos seeds
