摘　　要：高超声速飞行器具有重要战略价值,但难以进行全程和整个飞行包络的真实飞行试验,基于仿真技术进行虚拟飞行试验是其总体性能分析与验证的必要手段。针对高超声速飞行器在飞行过程中总体、控制、气动、结构、动力、载荷、防热与热环境、飞行器运动学与动力学等多学科、多物理场强耦合特性,提出了高超声速飞行器高性能多物理场耦合虚拟飞行试验平台体系结构,建立了高超声速飞行器多物理场耦合虚拟仿真试验模型,开发了基于高性能异构计算系统的多学科综合虚拟飞行试验系统,为实现高超声速飞行器的总体设计提供了可靠、实用的验证途径。Simulation based virtual flight test has became an alternative way for the overall performance va lidation of nearspace vehicles, which possesses strategic importance for national defence. But there is no success overall performance simulation for nearspace vehicles due to the compositive complexities from complex compu- tation, uncertainty and time variant characteristics, especially for the coupling dynamics among multidisciplinary systems, including integration design, control, aerodynamics, structure strength, material, vehicle kinematics and kinetics, hot defend, etc. Therefore, a virtual flight integration test approach is proposed together with a simulation model for multidisciplinary coupling dynamics and a high performance computer based simulation platform. Thus a way to overall performance validation and evaluation for hypersonic vehicle is presented.
