Skybike Evolution - Foot launched Aerobatic Human Proshetic Wings

This video takes you through a journey of the evolution of my Skybike, from the earliest days 14 years ago right up until my latest test I did in 2014 hope you enjoy it

[@CuervoRC]

Some time ago I did the calculations and a paraglider needs about 7 HP to fly. This ornithopter is heavier, less aerodynamic, and with very little wing area. A human at most produces 0.8hp , and for a few seconds, It is impossible for it to fly.

[@GregoryWingmaster]

I beg to differ, a number of your assumptions in your flight performance calculations are clearly very different to mine. Like Coeff. of drag for skybike vs paraglider. (strings create a LOT of drag)

[@CuervoRC]

@@GregoryWingmaster I have not really taken into account the drag to make the calculation of energy consumption, only the meters of height lost every second to maintain the proper speed for flight. With the height you lose every second and the weight of the aircraft, you can calculate the energy you need every second and then get the power. An ultra-efficient glider that loses the same altitude every second but moves forward more, is more efficient, but if it weighs the same it would need the same power to fly.

[@CuervoRC]

@@GregoryWingmaster You can calculate the power your aircraft needs to fly. Look for a slope and make glides, see how long it takes to descend and with the weight you can calculate the power, calculate the potential energy you have spent, for example 5 meters of difference in altitude and 100kg. and based on the time it took to lose those 5 meters you can calculate the power. when you start flapping the efficiency will probably drop. But at least you have a reference.

[@GregoryWingmaster]

you do make good points and there are indeed still some things to be discovered. Bear in mind that human powered flight has been around since the sixties Gossamer Albertross by Paul McCready. So we know that a human is powerful enough. We also know that flapping is a more efficient propulsion method than a propeller.

[@CuervoRC]

@@GregoryWingmaster Small scale flapping is more efficient, but you know that aerodynamics don't scale well. All the large scale ornithopters I have seen did not perform well compared to propellers. in fact a human powered ornithopter was made and it only managed to maintain altitude for a few meters but did not maintain flight. Another experiment I think that you can do, is to mount the aircraft on a bike and see if on flat terrain you are able to maintain the 30 kmh needed to fly with those wings. The bike chain is more efficient than any propeller or flapping. And so you would have a rough reference of how much force you would need to counteract the drag of the aircraft. Best of luck, I subscribe to follow your progress.

Flying as alao been my dream, ive never conformed with aeroplanes, I Want to use my own arms. But because i wasn't born with the building talent i can't do anything but dream about it, or in this case, trust in people like you to make it posible. Please never give up. I find every video soooo fascinating, I Love the design of the wings and looking at them every second of the video, so satisfying and aerodinamic looking. Keep on

[@friedrichtint488]

Ooh yeah, really looking forward to your next video :) i hope you will make it electric, like an exosceleton, super strong flaps at your own control, it was once a fake video when Playstation move came out, make it real

[@GregoryWingmaster]

thanks man....i have found new inspiration.......new prototype coming soon

[@Robalator]

This amazing I have sketches and blue prints for an articulated wing glider this is like my dream come too life ❤ bravo! Keep going!

[@GregoryWingmaster]

Thanks LordBatey..........why dont you share your sketches and together we make it more likely to manifest sooner

[@Yace]

I believe in you

[@GregoryWingmaster]

that is crippelingi........thank you.....i wont fail

[@moomoolaka]

I support your idea i think its cool. Just think of maybe a redundancy for the wings so that if you hit a big gust of wind the wings don't pull back past ehat your rotator cuffs in your shoulders can take plus it may add stability so that you have more surface area for lift and dont drop out of the air like a rock if your flying

[@GregoryWingmaster]

Thanks for the encouragement....you make some good points....next video coming soon

[@9DRK]

​@@GregoryWingmasterHello! Please try modeling a suit off something big and heavy like a quetzalcoatlus! They are huge prehistoric reptiles the size of a giraffe that were able to fly! They were likely very poor at take off, much like albatross, but would leap up off the ground with their strong legs to fly.

me to

[@Jacksonderamos]

put a jet engine and it will leave the ground

[@abundantYOUniverse]

First! LOL Nope!
