The fast-optimization for configuration of hypersonic vehicle

Strong ability to fly, good stability, controllability and the thermal environment are the main goal of optimization for configuration of hypersonic vehicle. For the requirement of engineering development efficiency, it needs to determine the main dimensions of the vehicle quickly. During the fast optimization for configuration, Aerodynamic characteristics evaluation uses a more efficient engineering calculation method about Dahlem-Buck, the evaluation of thermal environment is analyzed by an engineering rapid assessment model, the models of flight ability and thermal environment parameters is built fleetly, based on the character of quasi equilibrium gliding. There is the analysis for the relation between configuration parameter and drag-to-lift ratio, lift load coefficient and other aerodynamic character parameters, which Determines the direction of optimization for configuration. The method makes the closed-loop optimization which has preferable application for project.
