      I'd like to ask you to look into the Prandtl Flying Wing. In that case I do believe birds are the solution and I also think it can solve one of the major issues that blended wing aircraft face which is the heavy reliance on fly by wire for stability without an elevator/stabaliser. It would also appear that the YB-49 instabilities would also have been resolved with this knowledge.

      Correction: at 1:43, you said that an ornithopter is a flying machine that runs on only human power. That's not true, the word "ornithopter" means a flying machine that gets its thrust by flapping its wings. There have been human-powered planes that used propellers run by pedal power, and there have been planes that flapped their wings (ornithopters) that were powered by a regular engine.

      Well Peter..++ for save Energy.. birds flap their wings going up.. then glide down resting.. then go up again..++. So the obvious question is.. To save fuel.. a airplane should not climb up and then glide down slowly some Km with his engines in idle... then climb back up slowly at half power.... and then down again??.... a computer should do that to find the best descent and ascent angles based on passengers comfort..and the maximum fuel economy ++++..you know so the fuel can be wasted by servers and endless lines of other devices for stream over and over the same song or watch meme's..+++...

      Aircraft can also save several percent of their fuel by flying a little slower, whilst being mindful of stall speeds, etc. Another approach is to pick routes and altitudes with the best wind directions and velocities.

      The military has drones in development to be controlled by a single aircraft, so why not for commercial air. It'll require additional sensors and processors for aircraft, but then the lead aircraft acts the brain and communicates via RF, like blutooth, to those riding its wake. Assuming they're all going to the same airport, arrival separation could be started during initial descent when they're 20-30 minutes out from landing.

    I'm a glider pilot and fly regularly with birds in thermals. That other day I entered a thermal, a bird joined me. I orbited the bird as usual, and as the thermal got weaker, I left the thermal. The bird left the thermal right behind me and started "geese-ing" just behind my right wingtip. I noticed him following me, so I flew some slight turns and he followed the slight turns. He was apparently using my wake turbulence to save energy, for a couple of minutes. Or maybe he was just curious. Anyway, it was interesting to watch, I've never seen a bird following me before.

      the concept of optifly is pretty cool. The separation would need to be managed such that following aircraft would require separation from their normal flight position rather than their optifly position so that they could resume normal separation. They would effectively have to "Crowhurst" their normal slot when in opti. If they are all connected, the ability to have closer proximity as the system isn't trying to detect something, it's actually in contact. If they can get the LIDAR to pickup uplift, I think it could be more stable being the wings are fixed. I think it's really exciting opportunity and super interesting reaearch

    If we master wake-energy retrieval, I wonder if it could be used in emergency situations as well. For example, if a 4-engine airplane has a problem and is down to 1 or 2 engines, could another aircraft be diverted to take the lead position and make flying easier for the injured aircraft, providing more lift and/or distance to get to safety.

      I was thinking that myself, and even if a twin loses one engine, if its paired , then in theory it wouldn't need to descend as far to stabilize, which is less fuel burn, but the other plane would have to descend as well...... just a thought. You lose the gain you get normally.

    My aircraft design professor, classmates, and I are working on a "gust load alleviation system" for aircraft that uses the same idea how a birds feathers actuate and change the camber of their wings when they hit a gust or are controlling their direction while gliding. We are hoping to eventually even have small scale models that implement this and work our way towards a full flight control system using these adaptive wings. The system we are using to do this is something called Pressure Adaptive Honeycomb. This system is basically a series of cells that run spanwise along the trailing edge of the wings that pressurize and depressurize to flex the wing up or down as needed to alleviate gusts or to control the aircraft. We will actually be presenting a paper on this in January at an AIAA conference! It's so exciting to see that the industry is working on many ways to copy mother nature's wings!

    I can see a form of autopilot with plane to plane communication being required to get the best out of GEESE - network the planes together when they enter a formation and they follow a kind of 'buddy' system. That way they can adjust for eachother's course corrections, communicate weather and LIDAR data between them, and also notify each other to increase separation if one plane detects a fault, excessive turbulence or an autopilot disconnect.
    Without the automation, is there an argument this increases pilot workload and fatigue on those long haul flights where there'd usually be many uneventful hours?
    I reckon the most complicated part once implemented will be the airlines deciding how they account for one plane getting a free boost to economy while another foots the whole bill... maybe have to calculate the % benefit per flight and establish a payback programme between each other or agree a rotation.

    17:30 partially relevant experience I have in regards of "feeling" the air. I ride a fairly low power motorcycle (18kW and fairly draggy)
    The lower power nature of my bike means that at highway speeds any change in drag becomes immediately noticeable.
    So when I either want to maximize efficiency and or ride at higher speeds I put myself in the wake of a truck, van, SUV or car. Depending on wind conditions I may have to ride a fair bit to the side of the lane or get closer and to the side to be in the wake.

    Birds do not have a rudder. All aircraft including fighter aircraft have rudders. Just to state the obvious, rudders add drag and show up on radar which is concerning particularly when making low-altitude military attacks. Yes, the rudder corrects yaw during banking turns, but birds correct for yaw by minor increases in wingtip drag on the wing on the inside of the turn. I just have to watch birds in my garden to see this. This is my registered design for an aircraft of the future.

    A winglet is essentially a propeller blade, but instead of rotating in still air, the winglet stands still in rotating air, harvesting energy from the vortex and giving the wingtip a push forward. Also check out Albion Bowers work on the Prandl Wing.

    Active boundary layer control has been around a long time. Used on jet fighters of 60s vintage to lower landing speed. Given the computational power at hand, this might need a revisit for airliners.
    Peter Garrison wrote in the 80s (?) FLYING of a Japanese plane that manipulated the BL. The plane flew level by extracting its energy from the air. The wing cooled the air as it passed thru, the heat energy released propelled the plane. The pilot listened to the BL thru wing embedded microphones and guided the plane to stay in the sweet spot. Now readers, I’m reciting something read 40 years past, keep this in mind.
    Unlike airline pilots, birds have brains. That is, brains directly connected to its wings. Stronger quicker feedback and response. Moreover a bird can warp and contort its wings…we’re stuck with flaps. Cheers

  • @mitcho04
    @mitcho04 17 дней назад +3

    I'd suggest the wake turbulence is more due to the spanwise flow of air from under the wing to on top of the wing at the tip, less of the pressure differential in a two dimensional wing.

    Years ago, before Austin moved its main airport to Bergstrom, I was riding my bike down a road just west of I-35 in a quiet neighborhood that was right below the flight path of the old runstrip. I got startled out of my wits and almost crashed when a very loud noise echoed all around. After about half a minute, there was wind. I went back several times later, and there were several different features of this phenomenon. The most interesting to me was the collapsing of the wingtip vortices. That is my own term, but I don't actually completely know what's going on. Here's the sequence of events: 1) the aircraft passes overhead and lands. 2) some time after the plane passed over (about 30 seconds if I recall correctly, but I think it varied by aircraft type), a loud noise could be heard that generally followed the aircraft, but it wasn't linear. It followed the aircraft in a chaotic pattern, seeming to go back and forth. The sound also seemed to echo within the tubes formed by the wingtip vortices. 3) some time after the startling sound, the rush of air arrived as the downward rush of air from the plane reached ground level.
    I've tried a few times to experience the phenomenon after the airport moved, but I have a feeling I can't get to the right position (distance from the landing zone). Also, aircraft now generally have winglets now, and they didn't when I experienced this phenomenon.

    That's pretty funny, i was talking about an idea like the Fello'Fly/Geese idea after watching an episode of Mythbusters about winds and streams.
    A kind of fly-highway, after discussing it with some commenters, i think we decided that it would be cumbersome and probably inefficient in one way or another and that only army formations would benefit from it, even though you don't really want to become a group of targets.
    Using jetstreams is probably still more easy and takes less planning or rerouting flights.

  • @michallukac8271

    This seems to be actually really good idea. Taking into consideration aerodynamics is similar to hydrodynamics, riding in V formation is used in flatwater kayaking where followers catch the wave of lead kayaker and save a lot of energy, but same as flying geese, they need to adjust the direction and power output a lot (every stroke) to not lose the wave or crash others in formation. In group of 4 riding in “diamond” formation, the person in back can save the most energy.
    I believe using this technique in aviation should be possible. But in the age of autopilot and fly-by-wire, when pilot can’t “feel it” like geese, to constantly adjust the flight control surfaces and thrust to fly safely, I believe the only possible solution is communication between the planes for positional awereness and changes in direction, in combination with AI analysing data from sensors, but I believe in today’s world it is possible and if well implemented, fuel savings might be higher than now expected.

    Bird have a bunch of sensors attached to each individual feather. They are able to detect, actually feel the forces acting on them. Even torsion. Their nerve system adapted to calculating all the necessary muscle action literally on-the-fly. Aircraft will also need quite a lot of new sensors on the wings. Fuzzy logic in conjunction with properly thrained AI models will come handy.

      I think geese fly in formation because of slipstream.Basically the bird in front creates a pocket behind it with less air to hit the bird behind, thus less drag for the bird behind , less energy required , less food required.
      How about the bird in front ,which fully hits the oncoming airflow? Well fun fact , the birds actually swap turns

    Not natural but still untapped: solar panels on the wings (ultra-thin ultra-light ones). The engines don't need to generate the electricity anymore so the fuel that this would have used is now saved. It could also reduce usage of the APU and/or reduce ground idle/taxi fuel consumption by temporarily turning the generators into motors helping to keep the engines spinning with less fuel. Solar panels also get a lot more efficient at altitude. Maybe even use the generators as motors at altitude, this may even increase max operating altitude etc. All this could have a cascading effect that further reduces fuel burn by secondary/tertiary effects.

    • @miskatonic6210

      Good luck producing relevant amounts of energy with solar panels on wings. And they are dead weight during nighttime no matter how light they are. And they would need to be very, very flexible and durable, because wings need to resist a lot of force and bend a lot. And would need a lot of care when cleaning them. And so on...
