Thank you for another wonderful introduction into a fascinating topic. It's an exciting time for aeronautical engineering, especially with the development of memory materials, AI and so on, finding new ways to remove the limitations inherent in traditional design. Yet another master class on information presentation! Cheers from Sydney - Dave
If we can scale up Transwings it will change the whole industry you will no longer need runway And the military application is huge The logistical fleet will become unstoppable
This looks very interesting, folding wings could be the future. Foldable propellers also make a lot of sense. Telescopic rotors does look like it is service prone.
THey said the same thing like 40 years ago... Adding more points of failure just means you made a new weak spot where reality is going prove you wrong.
Another excellent video. The XP-4 is an intriguing design and I wonder why it has not been used before. Do you know if it is because of dynamic control challenges or purely mechanical ones, a combination, or something else? One thing this video has got me thinking about is how airframe/wing shape and shape transformation changes energy needs in different flight regimes.
For low induced drag there really is no substitute for high aspect ratio, like a glider wing, but the challenge is then wing weight fraction of airframe. With increasing battery life and safety the possibility of using structural batteries in at least the wing root begins to look favourable. The challenge is access the structural battery in the wing without introducing features that trip laminar to turbulent transition. The latest gas sampling sensors can also significantly reduce the risk of thermal runaway causing structural concerns. Hopefully certification regulations, like CAP 482, will soon give designers clear guidance on what is required for aircraft propulsion batteries. As battery energy density improves then higher altitudes will allow higher speeds for a given wing design. Glider design full span flaperons is definitely the way to minimise drag over the largest speed range for a given altitude. I'd like to see a move from propellers to rear ducted fans as this means landing gear length can be reduced, with a whole heap of weight & usability advantages. We're all waiting to see whether X57 Maxwell distributed propulsion still allows low drag laminar flow aerofoils.
In the 80s i remember reading an article in popular science about shape changing wings.i was an aviation nerd at the time.i dreamt of a neutral buoyant variable geometry aircraft with fanwing lifters. In my mind it was a thing of beauty.
Yup it's not a new technology but a new generation is hearing about it and thinking it is going to some how change the world... Too bad what looks like will work on paper or small scale doesn't work out at large scale specially when some of them just add more points off failure.
Yeah! A California thesis candidate has shown a variable swept canard foreplane could greatly improve an Space Shuttle at hypersonic speeds. A flat fuselage, closer to an Airfoil in global shape, will improve lift to drag ratio in any passenger or transport aircraft.
Reflecting on the experience with the V-22 Osprey, I am concerned about the safety, maintenance, and reliability of said aircraft with such complex designs.
Regarding transformium - Raja loha mentioned in vamanika shastra is a metal which have Ai there own mind and programmed to change the shape make a chair for passengers and also increased aircraft size and shape I feel very proud that this knowledge from vedas are re discovered and humanity benefits from it😊
@@WiltonSilveira I read this book in pdf it has vast knowledge how to operate aircraft make mine finding chemicals or machines with chemistry 🧪 book name - Vamanika shastra read it self you believe it
Chemical and Thermal based transforming should be more prominent in the future as electronic based manipulation has to many failure points and is subject to electro magnetic interference.
Putting engines and propellers in wingtips puts a higher structural load on wings under things as wind gusts, any failure will build a difficult to handle assimetry. I would not do this. Blessings +
When it comes to efficiency, a fixed wing concept beats a rotary wing design by far. Building a hybrid concept is even worse. It is a matter of physics. So why those hybrid or transforming concepts are under discussion that much? Because they suggest new business cases. Dream on. BTW. What the heck does a swarm of bots have to do with flexible wing design?
What are the reasons air limits free motion of planes? Direct force engagement (drag) and chaos. Drag is experienced when a vehicle has to travel at high speeds and it is minimized by reducing the contact area with air (aerodynamic design). The problem with this approach is that air molecules are swept into an uncontrolled movement (chaos) once they hit the vehicle in motion and it creates many different vortexes around the airplane, that prevent it from maneuvering at high speeds. what if we instead carved ridges into airplanes, that guide those air molecules all the way behind the airplane, where the chaotic movement is not a problem anymore? Imagine a modest Y shape ridged into top and the bottom of an airplane wing as well as the body. Instead of cycling around the front of the plane, the air would be guided by those ridges, which after first half split in two at a slight angle, that would force the molecules left or right based upon the airplane's movement. Imagine if we used a supercomputer to approximate optimal shape of ridges for the best air guidance at every possible angle and speed. Such plane could be made of lighter, less durable material as it would experience less mechanical stress and it would be way more maneuverable even at high speed, while saving the fuel at the same time, further reducing its weight.
It is also mentioned in Ancient vimanas and vamanika shastra about shakuna vimana how they got wings like birds showing movement while flights 😅 and now re invention of this technology is done😂
