This HyperTransport plane can carry more than a 747, fly further than any other cargo aircraft, and is far more fuel-efficient - this is the futuristic cargo competitor to the AN-225 built by both Boeing and Airbus.
In today's video, lets' explore the future of cargo planes, what would a future heavy-lift aircraft look like, and why it may never be built.
Let us jump in and if by the end of the video you feel like I've entertained you with this What If, then a like is appreciated.
The Antonov An-225 is the world's largest most powerful cargo plane. It can carry heavy and bulky items, like a generator or a mining drill, across the world. It was even essentially in transporting the engines for the Boeing 777X to the airframe across North America.
But for all its usefulness, it has some flaws.
First, the fact is there is only one An-225 in existence, with a 2nd airframe hidden half-built in a warehouse. This plane was originally built for the soviet space shuttle, and it was never really intended to be the defacto heavy lifter the world needs today. It is relatively slow, doesn't have a great range fully loaded, and burns a ton of fuel to get where it needs to go.
Simply put, it is old technology, its operators charge a huge premium to the market and don't have any of the versatility we have seen from more modern platforms like the 747-8 series - which is both a freighter and a fantastic passenger aircraft.
That leads us to the topic of today's video, what would it look like if Boeing and Airbus built their own version of the An-225?
This plane would be modern heavy-lift aircraft utilizing the very best new technologies, with the learnings from other passenger and cargo airframes like the A380 and 747, and with the combined efforts of both aerospace firms - a truly world class giga-flying machine.
This plane would be called the Proteus, after the greek god of the same name who served Poseidon and was capable of changing his shape at will to serve the task at hand. A fitting description don't you think.
This beast would have six high-bypass engines, such as the GE9X found on the Boeing 777X, or a future derivative, and would have a range greater than that of the AN-225 and at least equal to the 747-8F. With better engines and using learnings in fuel efficiency, we would expect this aircraft to have a load distance greater than 4,120 nmi (7,630 km).
Its unique design would afford plenty of advantages, with a double tail at the end to allow more space onboard, something that we have already seen utilized by the world's largest plane the Stratolaunch. Its engines and wings would use fuel-saving technology derived by the 787 series, such as saw-teeth" or "chevrons" on the back of the engine casing, to help reduce noise generated from the operation of the engine. The wings would use racked wingtip technology like on the Boeing 777X, to reduce fuel burn while cruising.
When it comes to cargo-carrying capacity, this is where it gets interesting. This aircraft would be able to load in full containers, like those found on trains, trucks and boats, and fill in the missing link found in intermodal delivery channels, directly into the cargo cabin using its own onboard lift technology.. This would mean that while it wouldn't be as long as the 747 and not suitable to tall items - like aircraft wings, but it would be more flexible for boxy items like giant turbines or engines.
We would require this aircraft to carry at least 200 tonnes, or around 450,600 lb, much like the AN-225. Likely we won't be able to carry much more, but the range will be extended with a full load on board. For comparison, the An-225 carrying 200 tonnes can only fly 4,000 km or 2,159 nautical miles.
There is even a possibility to turn it into a combi version with passengers onboard.
This leads us to the next point - the potential military applications. Such a heavy lift aircraft might actually be highly sought after by military forces around the world, able to carry tanks and other heavy military equipment's where needed.
The big issue with cargo carriers is two-fold. For one, cargo companies don't really care so much about fuel-saving and lowing the cost per kilo, because they are more than happy to simply increase the rate that they charge companies for transport. And they don't really care about being competitive, because where else are you going to go?
The second issue is the availability of other platforms. There are very few jobs that the An-225 can perform that other aircraft cant, and there is a lot of other aircraft.
For example, we have yet to see the next generation of cargo carriers, such as A350, 787s, 777xs, and more converted for cargo operations.
We also need to consider its market potential - or lack thereof.
But when the An-225 finally retires, the world is going to need a new heavy aircraft, and a concept plane like this Proteus HyperTransport will be waiting.
To clarify why Airbus and Boeing would work together on this. They were about to with the 747X and A380, and any future mega project like this would likewise follow a similar pattern.
Hey can i have the invite to found and explained discord
Nah son, this ain’t it.
I think if you could instead drop it to four engines it would be more appealing, then there is the economics of whether it would be profitable to be a giant air-ship... oh umm sky ship?! personally loved the video
So in other words they are no longer competitors but actually the same monopolistic company with different names?
The actual truck containers would need to be modified for aircraft use only made out of some lightweight alloy skeleton framework with carbon fibre sheeting to cut down as much weight as possible so that more cargo weight can be taken with a double stacking limit on the standard 20 foot containers. Cargo could be easily removed from the lightweight to be slid into a standard steel container for road transport so that new cargo for the plane can be slid into the empty lightweight containers specially made for the plane.

Well due to the tragic destruction of the An-225, this might actually happen now.
It might not. The whole concept shown in this video is flawed from the ground up. I have no idea why someone would make a video about something he put such little thought into.
Ukraine is planning on re-building the 225
I believe that Ukraine has billed Russia $5 billion for the destruction of the Antonov 225, and are planning on building a second.

I love these types of videos where we explore concepts made by nick himself
they are cool but they need to makrt it as his concepts and not real or ever will
yeah why would they make this plane
Yeah. I got really confused for a sec because I thought Nick was saying this was a real concept explored by Airbus and Boeing.
There really only needs to be one An-225 because it specializes in carrying weird corner-case cargo, so I kinda suspect it will be replaced by the lone Stratolaunch with a cargo capsule. Making a big weird cargo plane that carries shipping containers misses the point of why the Mriya is still around.
Yes for now but eventually airport space will become a concern. In the future I do believe larger cargo plane will become a reality to meet limited space so instead 3 aircraft land in an airport you will have one
It is still planned to complete the second airframe.. it is maintained very well where it is at now... Which costs a fair amount
@@marinusdedreu3833 Yeah all they need is to complete the second airframe with modern systems and they'll have the perfect replacement to last another 4+ decades. Imagine the AN225 with something like the GE engines on the 777X or the new RR competitor under development. Huge high-powered efficient engines combined with a spacious cargo bay like that would make for a serious improvement in payload and range, with the new limiting factor probably being structural rather than thrust lol.
@@MrMattumbo those 777 engines are _massive_ and may not work under the wing of an aircraft meant for loading with its kneeling system. I’d like to see Pratt & Whitney develop some larger geared turbofans that could power vessels of this size with increased efficiency and performance so they don’t die out quickly.
ITs booked nearly 10 years into the future and folks are practically begging for it to pick up their stuff. We could do with another one or two as it carries stuff you can't get on or off a ship easily.
“When the an 225 finally retires”
Well…That didn’t age well
it retired alright
@@amentco8445It retired very forcefully and ultimately
It's an amazing concept but keep in mind one thing: the flexibility. With this width there is almost no airport that can handle it
I agree. A bit limited where it could go. If they want huge cargo aircraft, use all the A380's nobody seems to want anymore.
The An225 was amazing in this regard, it can land on soft terrain!
Its so big it could carry its own runway
True, but if the problem is that there’s no way to bring large cargo in, it seems easier to widen an existing runway or just shutdown an active runway while this lands, unloads, turns around, and takes off.
Yep...& maintenance etc.
2:05 that's a funny looking 747-8 🤔
One of those newer ones named 747-8-787-Dreamliner, rare sight so lucky to record it on camera!
🤣
What’s even more awesome is seeing a DreamLifter taking off from Charleston knowing it has 787 “babies” inside it 😂
Got to say... that is a good looking heavy-lift cargo jet.
No. Thats weird. ^-^
So this is the REAL *THICCONOV*
Edit: so Airbus And Boieng collabed to make this but then it was never built
The AN-225 comes ot town regularly to haul large aerospace assemblies on to the next higher Boeing assembly plant.
That's a big, big boy. Always attracts gaggles of plane enthusiasts, cameras in hand. The crews love it too, since it stays several days, and they can go shopping!
I expect Boeing and Airbus would not work together as the development cost is not that bad. 4 GE-9X engines and perhaps 4 RR UltraFan engines can support a Mach 0.7 (207 m/s, 745 kmh, 402 kts) at 11,000 metres freighter of 840 tonnes MTOW. This would be comprised of 320 T OEW, max 320 T Fuel, and max 320 T PL. The 540 T combined max PL and Fuel allows them to range between 200 T and 320 T. It would look like a larger version of the AN 225. Using the main gear wheels of the Airbus A350-900 (35 T of MTOW each), it would have 24 main gear wheels on 6 axles each side. The nose gear would have 4 of the largest nose wheels available. The wing area would be about 1200 sq.m, and the wing span 100 metres with no folding wing tips. The length would be about 100 metres with the cargo cabin 60 metres long, 7 metres high with the floor 8 metres wide. There would probably be a lighter weight version with a cabin 10 metres high than could swallow a SpaceX Starship (50 m long) or booster without engines (both 9 metres diameter, with booster 70 metres long). It would not cater for external cargo and thus have just one tail. The width 2 metres above floor level would be 11 metres. Thus the cabin will have an 8 sided cross-section. An aim being to carry 4 F35 fighters ready for fuel and weapons, the hull of a 777, Starship, a SpaceX booster, or really heavy industrial parts. The cargo floor will need portable extra legs to load heavy items in through the nose or tail and place them between the main gear which are directly below the wings. The aim is a military and civilian transporter. If the applications are kept basis, the cost is kept down. The AN-225 was not that expensive. So, no inflight refuelling, or weapons. 50 to 100 is probably the demand.
We need a gigantic cruise ship of the skies. On board cabins and recreational facilities. Rock climbing, video arcades, mini golf, theaters, etc. Bring back the joy of flight.

Love your content so far , very informative & beautiful graphics
One thing I have learned in my fifty-four years of life is that anything is very possible!
If they invite Antonov this projects would be more interesting to see 😆

I’ve been waiting your you to upload finally
Even if this video was recorded before the destruction of the An-225 Mriya, it is really odd that Nick didn't add a footnote about it. This video was published nearly 2 months after the Mriya was destroyed.
I really appreciate you for writing the video transcript in the description. Not that i don't like to watch your videos but sometimes i don't have much time for YT videos
Been here since 1k subs and your videos are getting better and better.
I don’t need to enjoy the video to like it, the content is all I need. ❤️
Very epic channel!
Very well made and interesting clip, I would love to see this one getting build.
After the tragic loss of the An-225, this video gives us an idea of something to take its place. Hopefully, something rises to it.
Any 6 engine dual stabilizer will suffice !
Nice video Found And Explained i'm a big fan of you
Fantastic video 📹 👏
Thrawn: quality
Palpitine: more thiccness
Really cool love to see if it ever comes to be
With its massive size there aren't many airport that could accomodate it. Indeed, it might never be built. I think in the future supercargos will be handled by airships.
It surely won't airships as in plimbs are stupid
I don't know why you think airships will be used for carrying cargo, they barely have any lifting power
@claverse5478 Dude, the Hindenburg could carry 500,000 pounds, not light, and that's not considering that the hindenburg could've been even larger, airships also can use less fuel.
Great video, and it casually explains how companies stifle innovation and progress. Well done sir.
This plane would be great!
Not only as a cargo plane,but eventually as a passenger plane!
It could have an even more blended wing design and that would be even more fuel efficient!
I was lucky enough to see the AN-225 in Florida, though at the time I didn’t realize it was the only one.
It was blown up today
i love ur vids f&e
keep it up
Superb
This thing looks sick!
Aside from the time sensitive stuff, I think airships are a better option for cargo containers. If it's a time-sensitive container just put it in a 747F. It was designed to be big enough to carry cargo containers anyway.
If you need something bigger then a regular 747, have Boeing build you a Dreamlifter with an old 747.
Widen the front fuselage with nose loading and will be able to Carry longer and bulky cargo.
Very interesting
That plane is incredible huge. I live by a US airport. And when the Antonov comes in its so loud and huge.its huge. And awsome!!!!!
Thank you sir wonderful
I've been looking for a cool looking plane concept to steal for a game. And I'm making it a VTOL. Oh god
What game?
@@maxtube444 Stormworks, but I don't play anymore
Such a lovely mega plane!
From 3:05 - 3:10 I spotted a UFO!!!!
Those darn Arcturans sure like to keep tabs on our aerospace developments.
Kind of like a T-38 "pacer" plane flying alongside experimental aircraft during test flights.
The power plants I work at have had equipment delivered with the AN 225. The normal rates are crazy and the emergent rate is about double. Plus they make you pay a retainer fee in certain cases.
One thing to consider is the apron and manoeuvring area surfaces being able to take the load. I remember pushing back 777s in the rain and seeing ground water gushing out between the concrete paving slabs, as the undercarriage passed over them. Quite a lot of pressure loading there.
wow so wonderful this aircraft
AMAZINGNES!!!
I like this especially the fact that it can carry full containers full shipping containers this eliminates major snags and expenses related to loading unloading traditional containers into those used by the Air freight business considerably cutting the cost of transportation and logistics
Epic!
I want that as a wallpaper for my computer!
This design looks so cool.
Nice cargo plane too, congratulations.
That's one beautiful machine! Even if it is only a concept.
It reminds me of the "Zepher-1" from "Marvels Agents of SHIELD".
I seen a massive craft rectangular in shape but no wings or engines showing but looked like several evergreen freight carriers welded together it was at a hight but still looked like the size of a house to a fly
As someone who formerly worked in the aviation industry, I can tell you that while this is not a bad idea at all, it is incredibly infeasible. The reason being is that passengers and cargo (pacs in the industry) are assessed a "per mile" figure that calculates how much an aircraft must carry to make the operator a profit. Aircraft like that have been proven time and time again to not be economically sound due to complex maintenance, complex technology, special airport requirements for weight on the tarmac, and size.
This was also attempted by Lockheed Martin in their C-5A (now C-5M) Galaxy cargo aircraft. They had a study of making the Galaxy strictly a passenger airplane. The numbers were amazing, clocking in at 800 passengers well over 5000 plus miles. But the idea had no takers in the airline side as they were happy with the 747. Every attempt at making a "super airplane" has fallen apart when the numbers are crunched. The Boeing C-17A was offered as a civilian version to UPS and FedEx. They didn't want it, and a passenger model was displayed as well carrying around 250 passengers in basically a STOL (short take off and landing) with short, unimproved runway capability, very high performance, and suited for the short routes the Bombardier Challenger and ATR-72 regional planes enjoy. But always the same thing, nobody want to have to comply with strict size, noise regulation, and runway composition to get these projects off the ground.
Got a video on the channel all about the L-500, the lockheed passenger plane
I honestly never seen a giant concept aircraft like this one before. I really like this one a lot. And would you like to do a video about Boeing's mid wing double decker twin aircraft concept designs in the future as well as possibly do a video of Emirates triple decker APR001 just for laughs? Because I bet those would be a lot of fun to watch, I'll tell you that much. ;)
Proteus is ginormous but very elegant! I like it!
Thank you!
Looks like a hybrid between a BWB and a conventional fuselage - apart from the wide double tail boom. Maybe airports aren't ready for the bwb yet, so such hybrids could be the way, for increasing payloads - not quite a tubular fuselage or a BWB, but a widened blend of the two.
Useful to bring extra freedom to remote oil areas with the crane built in.
Hello, quick question. Would you like to start doing videos showcasing fan-made aircraft from the NationStates website at some point in the future just to change things up a bit? Because I really like that you've started creating your own designs of aircraft as well as recreating real-life unbuilt concept designs. It's just an idea I threw out, but an interesting and fun one at that though. ;)
Very attractive. I like it a lot.
love to have a desktop model like what was shown here .
Blended wing designs still have a long way to go let alone for such a huge aircraft
What a mega plane!

December 21, 1988 - February 24th 2022
Reminded me a little bit of the mega cargo plane (except the twin tails), which made a Kai Tak 31 like approach at the original "Ghost in the Shell" anime.
Found And Eplained: "Boeing 747-8
also FAE: 787 dreamliner
one issue, cargo and passenger flights use basically polar opposite flight schedules.
None of the freighters today were designed as freight haulers. For obvious reasons. A large freight hauler would not look like what any of us imagine. It would also not need 6 engines - 4 X 777 engines is plenty. Today an optimized plane might be competitive for certain types of cargo. It's a big project.
Reminds me of the Popular Science / Mechanics, pie-in-the-sky concept planes. Needs new aluminum containers though.
The hypercargo is one of my favorite
What an absolute unit of a chonker.
i love your videos move on like this
Hey do you have the 3d models of the aircraft you feature for 3d printing?
Is this an actual design or is it a pipe dream?
Pipe dream
Just remember, Antonov lead the way!!!
Hell yeah please build this !!! Looks like a Japanese Anime design ! Love it , about time someone built a large blended wing aircraft!
With the massive boom in air freight since March 2020, I'm amazed that the 2nd mothballed An-225 chassis hasn't been completed, with 21st-century engines and control systems. Six - or even four - modern engines would make this plane so much more efficient than the sole example currently in service, which is now over 30 years old.
Could Ukraine deliver it to be completed with Airbus' aid though?
Wich Programm Do you User for your Videos and Animations?
Im watching in 2023 and sadly the an-225 is no longer with us 😢 r.i.p
MONSTROSITY
I would think the future of large cargo aircraft would be focused around light weight composites and hybrid electric flight using superconductors. Some thoughts around this are:
1. When you look at the C5 Galaxy, it is a bit odd there are not more kneeling cargo planes. With carbon fiber composites, you could make a fairly flat floor that holds back pressure a lot lighter than the C5 Galaxy floor. I find it a bit odd that most cargo planes are so high off of the ground adding to expense in equipment to load and unload them and time to do the loading and unloading.
2. Do more rear ramp and lifting nose and ramp so you can more quickly roll on and roll off.
3. While I don't see standard heavy steal shipping containers used, maybe the carbon fiber / fiberglass composite equivalent. Semi trailers not hauling standard cargo containers have largely gone the route of being as light as possible in order to hold as much cargo weight as possible.
4. A superconducting hybrid electric system could be used with multiple ducted fans on each wing with ground clearance the main limiting factor on disk size with number being targeted around thrust needs (so probably more typically 2 per wing) and one straight through jet engine per wing to efficiently produce thrust and use batteries to provide extra power during takeoff. Go for fairly low sweep to no sweep on wings on the cargo planes as the speeds will be electronically gear reduced. The premise of the electronic gear reduction is a straight through jet engine is more efficient than having the big bell on the back to slow down the air over the turbine blades. Then turn a superconducting generator to feed power over superconducting power lines and in turn feed into superconducting ring motors attached to the blade tips of the ducted fans. Have superconducting wires crossing the wings so if the jet turbine goes out on one side, power can be distributed from the remaining turbine for good torque balance. Have multiple traction batteries in the wings and batteries in other parts of the plane for redundancy and resiliency. Not everything needs to be superconducting, but batteries near where power is needed tied into the propulsion system could be handy for severe faults like holes ripped into the plane and wires on other lines severed allowing local battery power keeping parts of the plane powered and maybe even falling back to radio controlled from the cockpit until an emergency landing can be made. For a cargo plane in particular this could be a payload is hazardous and damages the plane in a way that would bring most planes down through loss of controls, but this plane stays in the air as localized batteries and radio control keeps those flight systems and control surfaces working. Instant power from the batteries could allow for short takeoffs and landings while keeping the jet turbines reasonably small and efficient as they only need to provide level flight single engine out power at not too high of an altitude and the average level flight power at the max rated altitude with the batteries handling the shifting needs for shifting air currents.
5. The coolant for the superconductors could be LNG (liquefied natural gas). As this boils off, it can be fed into the jet turbines as a supplemental fuel. The attic space of the cargo plane could be used for this. A C5 Galaxy for example uses the top area for passengers, but most cargo operators are not interested in shipping people around.
6. Carbon fiber composites leading to strong and light wings, plus batteries already adding weight to the wings while making up for their added weight by allowing the plane to burn a lot less fuel, leads to the potential flexibility of either hauling a lot of weight with a small fuel load for a short hop or cutting back on cargo weight to carry a lot of fuel for a long hop. Also with the plane being a lot more efficient, the cargo capacity hit for longer hauls won't be nearly so great.
So yeah, you put this all together and you have a very efficient and flexible plane that can make it to a wide range of airstrips due to its short takeoff and landing capabilities while slashing fuel consumption by flying significantly slower than normal jets, but not too much slower. So maybe for a cargo plane you target a cruise speed of 700 km/h where say a Boeing 747 cruises at 903 km/h. Then maybe with all of the air frame and propulsion system efficiency gains you end up with say a 45% improvement in fuel economy and corresponding range increase for a given amount of cargo if say you built a 747 replacement plane. With the money saved on fuel, higher loads for given shorter than maximum range runs, and more airports that could be used with the planes more fully loaded due to the ability to use shorter runways with high loads with a battery boosted hybrid drive system, and materials used allowing for a lighter quick load and unload plane design, plus a new lightweight shipping container standard, such a purpose built cargo plane should become a popular, successful plane and start getting back into larger sized planes being successful designs again.
Going the other direction to smaller cargo planes, maybe you have a VTOL design that flies more like a drone when taking off and landing and then transitions to level flight, say wings that quickly swivel as well as multiple variable pitched props. This would be made efficient by flying mainly on batteries when taking off and landing as this vertical flight needs a lot of power for a short period, and then have smaller turbines provide the power for level flight with most of the props feathering to reduce drag. The idea being your large, long haul advanced hybrid electric cargo airliners will fly into the regional airport. Then the smaller VTOL capable aircraft could cover the region flying to small landing pads at or near where the cargo is needed. Especially with containers, just unload a container from the big plane, load it onto the smaller plane, and then fly that smaller plane to the final destination. A place like Alaska would be a more obvious choice for this as you fly a big plane into Anchorage and then instead of flying really small planes into little towns, a much larger VTOL hybrid electric plane makes the trip and even handles bad weather and a messed up runway out in the middle of nowhere. But there is really all kinds of places where this comes in handy such as doing air mail / cargo to a number of towns and small cities too small to have a major airport over a wide geographic area.
I think maybe you’re underestimating the difficulty of keeping existing superconductors cold.
where did you get the 3D models for the hypertransport?
RIP AN225
Great plane, if ever built.
Okay, nice shape, but what if you turn this model into a An-225 variant?
A true-deck cargo deck might be possible, if wanted.
Basically, what if the nose section IS a AN-225 and the tail sections also are more like it?
What if it used AN-325 engine mountings?
Yes, scale some part up a bit, while keeping a close eye on the AN-225 hull design & layout.
The two tails, if more AN-225 like, could thus BOTH have the loading materials storage section, while a back-ramp to the (main) cargo-deck is added.
Might allow the addition of a few tractors with lifting & pulling abilities, in the tail sections, since there would be more room.
A passengier deck ABOVE the cargodeck, with suitcase storage in the back-end of it, where the plane is wider.
Also handels safety problems in terms of wide, by storing it there, in the mid-back-end section.
Add sleeping places besides & before it, to lower it even more.
Keep the ability to carry a shuttle on the back, see if the weight can be increased, since you never know.
The (main) cargo-deck might now be bigger as well, probably longer, but wide & height is the real question, here.
Better engines, that don't drain the tanks that fast, bigger tanks, more engines, heavier loads.
What can you do if this was turned into a AN-425 concept?
Lets dream, shall we?
This plane could finally carry my house now I don't have to pay for a hotel when I travel😂💵💵💵
you don't have to worry about paying for a hotel
but you'll have... well...
other things to worry about
How about something larger? Using all turboprops for efficiency, 3 engines on each wing, 2 in pusher configuration on the tail for a total of 8. Of course, the turboprops would mean that economy cruise speed can't be more than mach 0,65 but if you can carry 1.500 people in "economy plus" configuration, I'd say going 10% slower is reasonable. I'd rather arrive well rested after a 14 hour flight than being awake non stop for 12 hours.
Airplanes are slowing turning into Pokémon.
Video on Stratolaunch maybe?
Even if the plane were to be marketed to the military, would it even be as useful as a C5? The big concern I have is that the cargo it placed to the sides of the door. Seems like it'd be a hassle at best or a risk at worst if you need to use it for airdropping cargo.
