Abstract:it deduces the helicopter rotor blade motion and give the aeroelastic stabile condition. The variables is the offset of hinge pretwist angle, coning angle and element mass of blade. The constrains are the stable parameter and frequencies. The objective function is to minimize the blade mass. Using the Sequential Quadratic Programming(NLPQL)algorithm and reliable optimization. It is the result that the blade mass is increased under the constraints being satisfied and all the design parameter’s reliability is 95%. | |||
