| Abstract: | By analyzing interference between main rotors and the interference between rotors and the fuselage a intelligent algorithm is developed.General parameter optimization of the tandem helicopter with twin rotors based on the genetic algorithm is presented.To develop a mathematical model for the optimization design, firstly aerodynamic interaction effects of tandem rotors are analyzed.The model is built by considering the transportation efficiency as an objective,flight performances and the weight efficiency as constraints.An improved genetic algorithm is used to optimize general parameters.General parameters of CH-47D tandem helicopter are optimized by a design example.Results indicate that the method is feasible and efficient. |
