elicottero "umano" a pale controrotanti - human powered helicopter

[patrizio1romano]

Non sarebbe meglio un sistema a pedali?

mandi! ma di dula seso?

dintorni di povoletto... tu chi sei? :) ciao

furlans, e tu cui setu?

good back and ass excersize. no but really nice work.

[DickWeinerUSA]

Your design is ingenius as well as elegant. One major drawback appears to be the use of iron/steel tubing and fittings. Aluminum in the right places will lighten up the mechanism. Also, you seem to be using actual helicopter blades. If composite materials are available, try making some larger, wing-like blades. Ciao!

bell'esempio di ingegneria.. ma a cosa serve?? :D

[GreenAce92]

hahahaha it's a vertical rowing machine

don't know if this has progressed much in the last year... but if you add a shoulder strap or bar to hold you body down you can use all of your muscle power without depending on gravity or have the handles pull in the opposite direction of the feet, though this may be very hard on the body

[pedfall]

This is very cool.... but since you are in essence pulling yourself up with each pump, the only lift provided would be from gravity pulling yourself down... You must have noticed there was a point where you could have worked harder physically, but you were limited by the time waiting to "fall back down" to the starting position. So with this design, you would never generate enough force, since gravity would not overcome itself. Still, very cool! Almost there.

Very ,very clever approach the most minimal design I've seen yet, looks to me if the blades were maybe longer with a bit more surface area and a little more pitch ,and if there were a way to achieve a higher prop rotation ratio to the physiomechanical energy input ratio. you might get lift,and make it a bit less strenuous to maintain for a period of time.I think you're in the three ring,keep at it. your engineering appears to be sound. you just might pull it off..

[timatlightbox]

This is a great idea, can I suggest to find a way to push with your hands rather than pulling the same time you are using your feet, this way you will get a lot more force into the system as you are pushing against it with your hands and pushing also with your legs.. with your current mechanism the maximum thrust you'll ever get will only be your own body weight and we can each push probably twice as much if we did a little training.. get my drift?

[gabrielbenitosobrino]

tienes que ponerlo encima de una bascula y probarlo, para ver cuanta fuerza hace y ver cuanta fuerza le falta

[batu69]

Fantastico! :-)

[Pluvio]

bellissimo..... senti in sottofondo la quaglia che chiama

[leviterande]

this is so mega interesting

[humnpwr]

love your video and machine

[h4ppydriver]

if that is really a restored prototype from the 50's, the materials are probably too heavy.

carbon fiber should be a good component to try (but expensive :( )

the way i see the main invention, the posible sustentation granted by the upper helix makes the second almost useless. Due to the air flow pulled down the second helix might rotate at higer speed than the first, or just be removed (reducing weight)

the pump system looks cool :)

keep on the good work

[pazzoperparapendio]

per fare ginnastica è ottimo!!!! ma che cazzata!!!!comunque bravi almeno vi tenete in movimento ehehehh

[TheTomLangley]

I agree the drive system is ingenious. I'm certainly no expert in aeronautics but I think the rotor blades need to be much bigger in order to create enough lift. Perhaps you could gear it like a racing bicycle so that it would have more revolutions for each hand & foot pull.

[Jonrobrt]

I am serious...there is so real genius in your design. Please use the success and genius of your drive system to continue evolving your craft!!

[dariobad75]

Ma daiiiiiiiiii :-)))))))))

[Jonrobrt]

This is magnificent!! Thanks for sending this too me. You have conquered many of the obstacles to success and your drive system is absolutely ingenious!!

Bravo!! Thank you!!

[friuli20032003]

thank yo you...  sorry for the language!! :) ciao
