Ornicopter(forced flapping heli design at Delft University)

Could a helicopter rotor be made even more complex?

Check out this design proposed that flaps it's blades for rotation and claims to be torqueless, so no need for tail rotor.

And I thought my ideas were out there on the edge.

I just repaired the link, should work now.

The link doesn't seem to work:confused:

Wow.
I wonder if the forced flapping would not be a bit hard on the rotor blades, especially on the blade roots.
And what do you do in a helicopter like that with your feet? Am I missing something, but I think they did not mention anything about the steering around the vertical axis.

Anyway, I do not think that this idea will ever make it to the market. Way to complicated. The additional weight of the blades and the rotorhead would offset the weight of the tailrotor you would not need. For the stability you would still need a tailboom. But a very nice subject to work on as a student.

Rather scarily reminds me of one of the "early rotary deadend" films we were shown at Ternhill (that dates me).

Seem to remember something similar ... which thrashed itself to death on startup.....probably due to absence of Homburg hat!!
