I've sat down and worked out some numbers. A good wing set at about 30 feet wingspan roughly 3 feet from tip to end can displace 12.8 m cubed volume of air per wing on a day temperature 20 degree dry air. Flapping the wing at 25 degrees down. 12.8m cubed volume of air translates to about 15.5 kg of air displacement per wing. So theoreticaly a sixty foot wing span by 3 feet could produce enough lift for a 60 kg person person.This is provided the wings were flapped property and doesn't take in account the weight of the machine. And would need to be extremely fit and strong.
I was thinking the same, just without the numbers. I was watching thinking "great concept " but you don't have enough wing area to lift a dense human body. He should work on inventing a human hollow boned skeletal transplant first.
You're not factoring in air resistance which, while also slowing down the wing, increases the thrust. You are correct in your overall volume, but a smaller wing moving faster can generate just as much thrust. The problem with human powered flight has less to do with weight and more to do with muscular structure. The human chest is not designed to produce the inward pull necessary to overcome their own weight. When you consider flying, consider that your chest and shoulders are basically lifting the entirety of your weight off the ground. So, basically, you're doing a hanging pull up every single time you generate lift sufficient to pull your feet of the ground. Do that a thousands time and see how you feel.
you could combine it with a supportive exoskeleton to produce a higher frequency and a costumized AI to fly mimic the movement better while having direct input from the pilot. I see this could easily be possible in a few years time :)
the wing design is certainly ok as a cosplay prototype, but you need a lot more wing area (and decelopment) to even get close to the upper range of bird wing loading (which is 20kg/m² but usually less than half that - you're probably around 70kg/m²). nevermind the fact that the empennage is not going to do a thing in this design. you are onto something though with the variable wing geometry. I suggest making a scale model and trying to fly that.
Yes indeed, he will not be able to wave his arm like this lol, this is why birds have very strong chest. He need a sort of machine. Or he will just get a cramp and fall.
Correct you are and we should definitely support as much as we can I hope he doesn't do like some companies that run to defense organizations and "government" agencies...this has more potential in the world of sports than the silly world of other people's insecurities and wars of delusional fleeting power and imagined self importance
As noted by other commentors, the human power to weight ratio is no where near enough to produce sufficient lift even for a very light person of 60Kg. However, if the wing area was sufficient to allow for gliding, all that remains is a way to get up in the air. I think the concept has to be re-thought in terms of a kite. That is a large enough kite/ wing structure, that can lift the person off the ground in a fairly slow wind speed. Thus an extremely lightweight structure is required as in a kite with a very large surface area. Thus one could imagine a kite tethered to the ground, on a windy hillsite, a person held within the kite, who is lift up by the prevailing wind. Once at height , he could detatch himself and glide with the aid of some human propulsion to extend the glide path. Wing flapping I would not use, but some sort of propeller could be a useful propulson , to maintain height, once the wind has done the heavy lifting and lifted you up in the air. Just an idea!
Great job buddy! Be safe. Never Give Up! I was looking at a tree today it was 10-12 foot tall. The tree was on a rock the size of a Jeep. The tree never gave up.
Carlos! Sou super fã de tecnologia aerodinâmica... Show o vídeo.... Equipamento magnífico tem tudo pra dar certo... Na verdade já deu, só acertar alguns detalhes e daí UP... Tmj... Abração do AVENTUREIRO PAULEK!
sem condição a "aerodinâmica corporal humana"ou física NUNCA uma asinha daquele tamanho pra o peso do humano e ainda colocada na altura do ombro nunca vai nem tirar o pé do chão... a asa teria que ter pelo menos 6mt de envergadura e as "penas" maiores 1.5mt e a fixação no centro da costa nosso problema é o peso haja vista o peso de uma ave proporcional à envergadura.... é so calcular kkkkkkkk
@@gilmarrodrigues9032 se for multiplicar o peso da ave e o tamanho da asa pro peso do homem ficaria tão grande as asas q os braços quebraria só Deus na causa
Hey there, im working on a similar device and its always great to see interest about ornithopter from other people too. If you dont mind me asking, how much does your device weigh? And have you been able to test the thrust created when you flap?
The Idea that People see Birds can fly with wings but neglect that birds have hollow bones, don't have a bladder and are basically the most weight optimized lifeform out there is just beyond me
Fantastic! Love the construction. Did you include springs to keep the feathers tensioned? I think you are onto a great concept, but have a ways to go before you are air worthy
You know with right type of funding he might just pull this off...yes his missing so many things for flight honestly his body would fail even if manages to get the wings but what I've learned from history and life is we have made impossible possible countless of times
@With Adan, here is what it actually is required to create a working ornithopter. Research the Snowbird, the first human powered ornithopter to fly. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WpobKBR6n9U.html
@With Adan, the host of this video will never have the funding nor expertise to create a human powered ornithopter. It would be easier to make a human powered airplane.
@@carlosornithopterlacuesta9786 carlos meu primo esta com um projeto e ficou muito interessado de falar com vc so que ele é do brasil ate instalou google tradutor co. Esperança de vc poder ler esse recado.
Wow this is AMAZING, your prototype is so detailed! The wings fit the motion of the arms like gloves! When able, how would one invest in your creation?
@@gamingwithowen1365It doesn't need a wingspan too big for human arms to control. What it needs is an electrical engine that draws air in from the front at high speed and pushes it down from the wings, aiding lift. It could also benefit from motors in the wings that take on some of the strain, reducing the effort needed from the arms, similar to how an electric bike works. To give the wearer the full freedom of a bird, it would have to be self-charging, to get rid of any dependence on external charging ports. This could be achieved by making the wings into solar panels. It's hypothetically possible to make artificial feathers that work as solar panels. It could also be achieved by converting the wearer's body heat into electricity, or by installing turbines to charge the battery during flight using the air resistance. Some combination of electricity sources may be necessary. So that's how to make it work, but to make it better, it could include fully feathered wings and a fully feathered tail that completely cover the arms, back and legs during flight, a wingsuit covered in the fluffier feathers that cover the rest of the bird's body (full body feather covering is good for insulation, aerodynamics and trapping layers of air, which also aid lift) and a helmet with a beak, so the wearer can pretend to be a giant bird. It'd be so much fun to fly with one of these things.
YOU IGNORED FLAP RATE AND AIR CURRENT WING-LIFT - with a decent design, "take off" by just standing into a breeze, or launch yourself with a catapult, or CLIFF-SIDE (hang gliders do it all day long) with a relatively small wing area for a given payload*. The Gossamer pedal powered aircraft used air current lift and not air displacement except for a very large propeller for forward / directional thrust. Solar powered gliders with very low mass stay up indefinitely. The angle of a bird's wing provides thrust and lift variably and very effectively - very high tech!!
Ye koi bata sakta hai kis desh ka chamar hai kyuki main batata hu india ke chamar ke bare me. Humare Gaon me ek jugti chamar tha ek din usne bhi is chamar ki trah udne ki sochi Or apni dharm patni se bola ke aaj main udunga vo boli kase usne kaha ke 2 chhaj ( chhaj kahte hai anaj saf karne ke liye lakdi ki tuliyo se bana hua ek choda sa bartan) mere dono hatho par bandh de Or main upar chobare ki chhat par jab chadh jau to Tu niche anaj ke dane bakher ke kahna ke aa mere mor ( peacock) Or fir main upar se ud kar niche aaunga. Us bechari ne asa hi kiya, boli aa mere mor or vo chamar upar se chhaj bandh kar udne ke liye kud pada niche aake gadh se pada tut gaye hath par. To ye bhi jugti chamar ki trah pankh bandhe ghum raha hai. Is se pucho bhai ye konse desh ka chamar hai? 😀😀😀
My good friend, it is impossible for man to fly without machine controlled wings. Human bone is heavy so the muscles cannot maintain long hours of flapping.

If only man could learn to fly...but alas... it is impossible. We are stuck on the ground, for eternity to look up and see the birds flying and wonder what it is like to take to the air.... oh, wait... this just in...humans have been flying for 118 years. What the heck is this guy thinking?
