Human Powered Helicopter
As the title suggests ‘Human Powered Helicopter’ is truly an interesting project. Man wanted to fly since the beginning of his history. People like da Vinci created designs of flying machines and dreamed of flying one day.
Human powered helicopter is not a new concept, this was created and flown successfully multiple times. As the name suggests the helicopter flies entirely by human power ie, mostly pedalling. (sorry to disappoint those who thought of Matrix movie like human cell power generation!)
If you are thinking this is  simple to create you may wrong. It takes a lot of engineering to get the right power to weight ratio to make this human powered helicopter flying.
Challenges:
- Get the right power-weight ratio
- Get the best rotor efficiency
The maximum height ever reached by a human powered helicopter is 3.3 meters and the maximum time it flew  (better say hovered) is 64 seconds, think of this jumping right into the project and take the hurdles seriously.
Checkout their video below:
If you check the video you will find that its structure is entirely made of light materials and has a minimal design. They also use large light weight rotors which rotates at a very slow speed compared to the pedalling speed. This is done to make sure that the four rotors will rotate with the power given by a single man. The use of a reduction mechanism reduces the effort on the legs on the man and helps to power all the rotors simultaneously.

Everyone has approached this the same way. Super light weight material and huge rotors at low RPM. I see a different approach. Since the inner 75% of a rotor only produces 25% of the lift and the outer 25% produces 75% of the lift, it makes sense to eliminate the inefficient part of the rotor. In fact if you replace the entire rotor with a disc, you could build up much higher RPM and then once the desired RPM has been reached, use an aileron system to actuate multiple rotor sections near the outer edge of the disc to produce lift.
Thanks for the input. Would you share any source of this info, so I can add those too this article?
Im like this project because of any other energy can’t to be used to drive the helicopter… I hope can I will implemented in this project under.
plzz add some new interesting topics
can we have some more interesting videos for the project.
