Optimization of configuration and trajectory for hypersonic vehicles
摘要
Abstract
Uptodate,multi-objective optimization is widely adopted in the field of hypersonic vehicle configuration design. Generally speaking,aerodynamic characteristics are determined by the vehicle configuration,and the capability of comple-ting the flight missions is determined by the design of flight trajectory.In this paper,the parametric geometrical configura-tions are proposed,and the aerodynamic characteristics are predicted by the rapid and effective engineering method.The configuration is optimized to satisfy the design goals of maximum lift-to-drag ratio and maximum volume utility ratio simulta-neously.And the optimization of flight trajectory design considering the integration of aerodynamics and aerothermodynamics is investigated based on a given configuration example.The detailed research indicates that the optimal configuration and flight trajectory obtained by the optimization can fulfill the requests of the designers,and the results can be used as the fea-sible schemes in the future work.This research has a very obvious background of engineering application and value of appli-cation extension.关键词
