I keep coming back to this video. It might be one of the lowest wing load vehicles and power-to-weight ratio vehicles of its size I have ever seen. Perfect for Mars flight (which is why I keep coming back to this configuration). Frank Ragallo (NASA Langley Research Center) pioneered this delta-shaped kite back in the 1960s for precision re-entry vehicle landings on Apollo. I think the powered Ragallo wing is worth another look for Mars application. -David North NASA LaRC UAS Team
Thanks for putting up your video,much appreciated seeing it. I really liked the slow relaxing flight. I'm working on a Bird kite at the moment, smaller scale with a premier style differential thrust. I hope it flys as well as your example. Are you still flying motorized kites? Keep up.the good work!
There is a way to improve the endplates, by putting cuts in them and bending them to create blades and angling them so the air comes over the drum and then gets exhausted outwards therefore increasing flow/speed😅 good work! I would like to see it incorporated into a horizontal fusilage with the drum at the leading edge of a wing so the useless air on the underside of the drum is drawn off and over a cambered rear section of wing/acceleration ramp/flap, have seen it demonstrated in a wind tunnel to great effect, and that's what I want to build for myself, something that looks like a jet but has a 'super circulating' wing and driven forward s with a EDF
I have a 6 foot wide kite printed and shaped to look like an eagle........ I also have a collection of old drones and cheap differential-thrust twin-engined planes. We now know what has to be done next !
You wouldn't have happened to been flying this over Portland Oregon yesterday afternoon at 7:00 would you? I saw on it almost identical ship like this. No noise except it was doing 150 miles an hour plus. I took video of it also. This is the only aircraft I've seen that looked like it
