It bet it is similar power to weight ratio, but athletes will exceed average horses. One horse power is 750W and this guy can produce a peak bursts of 500W, not sure about continues power. Average human can produce 100W.
the one problem I can see with a recumbent design is that there's less bike between you and the ground to absorb an impact if you have a hard landing. At least with a normal bike the wheels can collapse and absorb some of the impact.
imagine greta thunberd flying over the ocean to europe in this Edit: 1: God damn Im famous 2: But I just had a thought, if Greta Thunberg actually did this, and obviously ended up falling in the ocean, do you think she would eat the fish to survive?
An ebike being used for this seems like a much more viable option as you could have a longer gear ratio to the propellers without it being difficult for the rider
@@josephfreeman5289 Google it. "The Gossamer Albatross is a human-powered aircraft built by American aeronautical engineer Dr Paul B MacCready's company AeroVironment. On June 12, 1979, it completed a successful crossing of the English Channel to win the second Kremer prize worth £100,000. Wikipedia"
@@josephfreeman5289 There have been many human-powered aircraft over the decades, many records broken and prizes won. In 1979, the Gossamer Albatross flew from England to France - over 22 miles in under 3 hours - claiming the Kremer Prize of £100,000. There are various prizes currently available for human-powered flights but I'm not aware of any million-dollar prize. For what, crossing the Atlantic? 😊
@@josephfreeman5289 The first human-powered flight was over a century ago. There's a £100,000 Kremer Prize currently available from the Royal Aeronautical Society. What is this million-dollar prize for, exactly?
Look up what a glide ratio means, not to mention for a aircraft with such a high aspect ratio and low weight would probably be airborne for while. They probably also didn’t let their pilot go up that high in the first place.
This is really cool and reminiscent of the wright brothers as they designed their aero planes out of bicycle parts, as they were bicycle repair men. Looks like a fun ride, and one heck of a workout!
Human-Powered aircraft have traveled across The English Channel, and some have gone even further than that. With good engineering and a good athlete, the Grand canyon would be no problem.
The longest distance ever covered by a human-powered aircraft is actually 115 km, between Crete in Santorini. The channel between France and Britain has also been crossed on a human-powered aircraft.
I want to be clear, I am not saying that what the people in this video did is insignificant - what they are doing is fantastic, and I hope their next flight is even more successful! Just because people at MIT and aerospace companies built incredible bicycle-powered aircraft doesn't mean that trying to build your own isn't worth it. Even just trying to do it sets these folks on the path to being great engineers, and they are actually getting it off the ground. Could you or I easily do that? It takes research and dedication, and they can make their inventions way better. I started learning science by tinkering in my garage, and it led me to publishing papers at major institutions. I wish them the best of luck.
Imma send this to everyone who says they miss the olden times when inventors came up with batshit crazy ideas and just went on to test them by themselves
Thin, lightweight solar panel on wings. Small, light electric motor. As a bonus, spinning prop creates electricity, charging battery for when clouds come in. Just a layman's thoughts.
Yes I agree but remember that this is just a test , im sure that if they get it to work that chain mechanism would be failed proof or a backup would be in place. Its just my thoughts. Thanks for the comment, happy holidays
Thanhkyou for flying Ryanair. Last year, over 90% of our flights arrived on time. We hope you enjoyed yours, and look forward to seeing you again soon!
That was because the rear stabilizer was just flapping in the wind. Im guessing someone pulled down on it to generate the climb then once it flapped up he went right back down. The people who designed this dont seem to understand the basic principles of flight.
The wings are too flexy but with an e bike and tougher wings I see this working And a functional stabiliser, rudder, and ailerons would make this solid
Did they think about a gearing system? That would make things so much easier. Just step up the gearing ratio between the pedals and the propeller and you'll be able to stay airborne for as long as you want.
Bravo for this team. That is one tiny HPA. Something as small as a 200 Watt electric motor and a 1 pound battery could get this thing up in the air for a few minutes and let the pilot learn t fly the thing. Simple pitch stabilization would save the pilot lots of energy.
There was a version entered in a contest to fly a defined course around pylons. The school contestants used a bicyclist racer who could put a sustained energy into the flight. Every gram had to be accounted for hence no complete bicycle would have been included. I'm going by memory but I think a sustained output of 250 watts was required. Another effort was mounted to cross the English Channel. See: en.m.wikipedia.org/wiki/Human-powered_aircraft
На малых скоростях необходимо другое крыло. Слишком большая должна быть хорда крыла. Но по-моему тут никто не заморачивается. Технологически ничего не мешает запустить в этой штуке электробайк. В среднем эквивалент электродвигателя 250Вт. (Человек пиково выдает двести ватт мощности), ну и смотрите, чтоб взлетело...
If you could power the generator by pedaling or if there was some way to amplify motion with some kind of spring or gyro then dynamic power generators would be viable
Когда-нибудь, я уверен, создадут такой сильный и достаточно легкий редуктор, с помощью которого велосипедисты будут летать так же свободно, как пилоты планеров. Я даже название для таких аппаратов придумал: ВЕЛОПЛАНЕР.
You are loosing a lot of lift to wing flex, I believe the easiest way to reduce this would be to run Kevlar cables from the wings to the lower parts of the bike as trusses. The other thing I noticed is that you can probably cut 5kg of that bike. Last I would significantly reduce the amount of elevator movement, it looked like the big movements of the whole horizontal stabilizer made the plane hard to control as well as causing spikes of drag.
Could always hook up some sort of system that releases energy into a propeller or multiple. Also if they did that same technique with the torque bike they’d probably achieve enough energy to maintain propulsion and lift? Idk I’m not a scientist just a cool idea.
