Blended Wing Design: The Plane Type Of The Future?
Вставка
- Опубліковано 22 вер 2021
- Since the earliest days of aviation, aircraft have, more or less, looked very similar. While a lot has changed in terms of technology, the basic fixed-wing design remains the same. While a blended wing concept has been experimented with for decades, it’s only had limited success in the commercial sphere. But as manufacturers and airlines focus on efficiency improvements, could we see a very differently shaped plane in the future?

One way the blended wing design could be a real game changer Is in the cargo market. The huge internal volume could move substantial amounts of freight over long distances. I could also see it as a combi aircraft with passengers along the edges and a large internal cargo volume. As a freighter, it wouldn’t even need to be particularly fast. 400 to 500 knot speed with lite fuel burn, good short field performance and large carrying capacity could be popular.
In addition, cargo typically uses ramp parking, as opposed to jetways etc, so minimal infrastructure changes would be needed. It can park where current cargo planes park for the most part
And cargo doesn’t need pressurization so no pressurization issues of blended wing aircraft.
Actually, I think it would need to be at least 650 mph to really make a difference
Flying wings could definitely be a game changer, assuming of course you solve some issues first. One is safety, since you would have a more difficult time leaving the plane in case of emergency, simply because the surface area is lower relative to the volume of passenger a flying wing can have.
In case of cargo planes on the other hand this issue does not present itself, after all who wouldn't want to see a B-2 esque cargo plane flying
FINALLY! A body-lifting design that's for commercial use!
It was about time, since WWII the wing attached to tube (t-design) isn't used for it's wastefulness reasons.
Commercial companies take too long.
I think the current design would stay for a while at least
Video starts at 2:33.
Imagine a high crosswind affect that aircraft.
No mention of McDonald Dougles/Boeing project? I mean you showed the model of it, but again no mention?
I was hoping for some insight on how they are working some of the limitations. Pressured cabins, round shapes spread the forces equally in all directions. Flatten it out and the lever fources will rip it appart. The inability to change the wing shape during flight. The shape of wings change drastically durring flight. This allows them to fly efficiently a high speed while developing enough lift at low speeds to take off and land. I would love some insight on how the new designs are looking into these issues.
Really, we can see such an Aircraft!
I think Otto Aircraft's laminar flow designs are likely to be more practical in the short-term and their prototype has been flying for some months.
I thought the higher cross sectional area makes them uncompetitive with flying pencils. As wing materials get better and better, the gap between them gets worse and worse. I think blended are just good for specific applications that require it to be a certain size and shape. As it is, the shape of a fuselage and cabin is pretty efficient. Even the exits work well on a long plane. Im not sure a blended would work so well when you have 4 or 5 aisles trying to exit the sides.... Military may be a completely different story.... For commercial, if blended was more efficient, they'd already be in the air.
I don't see the huge blended wing being used for commercial pax use because what gates would you park them at?
Was watching a UA-cam video on a different channel, Beau of the Fifth Column. That was the first reference to this topic.
That I had heard of .
Like fusion power, these are always the future... Just out of each. I do hope the latest proposed project JetZero does go ahead though since I do believe in the design despite its limitations...
SEE BOEING X 48C BLENDED WING PROTOTYPE
I just don't see how it will be economically feasible to *construct* such aircraft in large numbers. Current carbon-fiber components must be cured in large, pressurized ovens (autoclaves). As wings and fuselage components are much longer than they are wide or thick, this means that the cross-section area of the required autoclave remains the same for longer components. Blended wing aircraft would require much, much bigger ovens to produce the necessary body component. Making a longer autoclave is much easier than making one that is extended in all three dimensions.
One other *major* consideration is that a single aircraft model family (737, A32X, etc.) can produce different versions largely by adjusting the length of the fuselage. Any blended-wing design would require a complete redesign in order to accomplish this. This alone would either limit the potential market of a given blended wing.
And, finally, would anyone want to sit in a seat far from the roll axis? If a 747 banks to 45 degrees, window seats move vertically a maximum of a couple of meters. The resulting acceleration is relatively small. At the edge of a bended wing, your seat might move 20 meters in the same amount of time and you would definitely feel it, turning a normal flight into a roller-coaster ride. Furthermore, to minimize this, the roll rate of the aircraft would have to be limited. Finally, adding mass far from the roll center will both slow roll rate (limiting maneuverability) and stress the airframe and flight controls.
Hello brother this is one of the best aviation channel on UA-cam ✌️
It's to much of a radical concept for 1 aircraft manufacturer to go it alone
I don't understand the change to hydrogen fuel? Isn't hydrogen more explosive and the reason why blimps changed to helium?
How is this different than the Boeing X-48 from 2015?
Boeing and Airbus have versions of the Blended Wing so the only difference is the X-48 is Boeing's version.
B2 design is decades old. Just a passenger version
It seems like blended design brings more problems than it solves. So, even if you addressed them, it would take less time to address problems of inefficiency with the current model or find a better one all together. Seems like a waste of money.
Good morning Long Haul, I have seen many designs for future aircraft, which will eventually be developed by manufacturers of aircraft, but one project or two projects that we should pay close attention to is the KLM project and the BOOM project to which United has the provision to enter this market firmly causing a great marketing impact. But don't be surprised if the Chinese leap ahead of their competitors.
Less aero load but structurally inefficient. For a shape that has to endure large pressure changes, it is far from ideal. Can't have real windows which are growing in size.
Then it could be use for cargo.
👀
I don't get the fascination with hydrogen. Presently, the only way to produce hydrogen in large enough quantities involves a process using fossil fuels. This hardly seems sustainable.
Just think, airlines can make 30% more profit. They have to make sure the benefits are spread out among all the stake holders. As well as the environment.

Mother goose?
Sorry to say this but I think unpolished way I don't have a pleasure to know your name
Nice video!! Very engaging from beginning to end. Investing in crypto now should be in every wise individuals list, in some months time you'll be ecstatic with the decision you made today.
Crypto is the new gold.
I wanted to trade Crypto but got discouraged by the fluctuations in price,
@@benjaminjohn5784 That won't bother you if you trade with a professional like Mr Timothy Gregg
I heard that his strategies are really good
@@greghamstrong4407 Yeah, My first investment with Mr Timothy Gregg earned me profit of over $25,530 US dollars, and ever since then he has been delivering
Am I the only one who thinks the blended wing design is ugly?
I hate it , it looks too wide
Personally, i think they’re beautiful. Personally that is.
The blended wing looks so ugly...... I hope it never materializes.
Of course we should only have pretty things in this world, with pretty being defined by you and imposed on everyone else. ... Sorry mate if these things have lower CO2 emissions or they are just cheaper to operate, they will be operating out of airports near you and no one will care what you think.
@@Dave_Sisson Looks like I irked someone... these ugly planes will never take to sky. Be rest assured.
I strongly agree but obviously we should do what’s best for the environment.
@@EvanAviator But of course these initiatives have nothing to do with the environment and everything to do with marketing.
