The Application Of Snel Stall Model In The Field Of Helicopter Rotor

In this paper, the Snel stall model was first applied in the helicopter field to solve the problem of determining the lift coefficient for helicopter rotor. What's more, a simulation experiment for the OA212 airfoils was conducted with the Snel stall model, by comparing the flap angle, the power of rotor and tail, the relationship of thrust and collective, and the relationship of longitudinal flapping and longitudinal cyclic, the effectiveness of the Snel stall model in field of the helicopter was verified. The result shows that the model contains no parameters compared with other stall model, which is more convenient for practical application, and it also shows good accuracy and strong practicability.
