Hello everyone,
I am a young research who is doing some numerical simulation of helicopter rotor blades.
Nowadays, I am computing the two blades AH-1G. It is a teetering rotor.
I need for my simulations to know the flapping mode of the helicopter for given flow conditions:
betha=betha0+A*cos(azi)+B*sin(azi)
I have the values of the A and B from the experiments of the helicopter but there is no data of betha0 (cone angle).
I may be wrong, but since it is a teetering rotor, is this betha0 (cone angle) the same as pre-cone angle?
Hope somebody can help me. Thanks in advance
