Abstract

For designing modern gyroplane with jump takeoff capability

the characteristics of thrust/lift system parameters are investigated

and a multiobjective optimization method is presented.To calculate thrust/lift

the mathematical model is established through numerical integral method based on blade element theory and dynamic inflow theory.The jump takeoff is modeled on the basis of autorotating rotor aerodynamic characteristics and energy equation.The impact of parameters on jump takeoff performance is analyzed

and a computation example shows that the model is feasible and efficient.The multiobjective optimization design of the parameters is carried out hierarchically by using improved genetic algorithm and design for six sigma(DFSS).The optimized result indicates that the method is accurate and the general performance of gyroplane with these parameters is advanced.
