Compound Helicopter Optimum Design Based on Genetic Algorithm

Abstract:

Article Preview

Install thrust propeller and wings to coaxial helicopter, constitute a compound helicopter. Compound helicopter has greater speed, farther voyage, while retaining advantages of the helicopter which can take off and land vertically without runway.Preliminary design is an important stage in compound helicopter design work. It covers aerodynamic analysis, flight mechanics analysis, dynamic analysis, flight performance calculation and weight characteristics calculation. These aspects intertwined, which deepened the complexity of the preliminary design. Use genetic algorithms to optimize the design of the general parameters. Under constraint conditions of meeting flight performance requirements, calculate the general parameters which make the objective function optimal. Objective functions usually include weight efficiency and Miri’s criterion. This method without repeated design can shorten development cycle, improve economy and ensure design quality.
