Multiobjective Optimization of Gerneral Parameters of High-Speed Compound Helicopter Based on Design for 6 σ
摘要
Abstract
A novel multiobjective optimization algorithm for the parameters decision problem is proposed to find the best design project of high-speed compound helicopter.The new algorithm can improve relia-bility and robust of the result using improved genetic algorithm based on design for 6σ.T he aerodynamic performances of high-speed compound helicopter are computed through numerical integral method based on blade element theory and dynamic inflow theory,so the constraint functions and the preliminary ob-jective functions are built.Design for 6σis combined into improved genetic algorithm and final objective functions are established.The multiobjective optimization design for high-speed compound helicopter general parameters is carried out with given payload.Pareto solution set is gained through the optimiza-tion method,and result indicates that the method is feasible and efficient.关键词
