Research on the overall parameter design based on the optimization of the aircraft model

With the rapid development of the economy and the continuous improvement of aerospace technology, Aircraft play an important role in various neighborhoods. This paper analyzes and optimizes the aerodynamics and drag of the aircraft, and then the minimum drag model corresponding to the aircraft is obtained through genetic algorithm. The results show that the minimum drag model of the aircraft is affected by the shape of the fuselage, wings, cabin, tail and other models, it is necessary to calculate the minimum drag of the aircraft through genetic algorithm is 5411884N. It is hoped that this research can promote the development of aircraft optimization in the aviation field.
