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。
Hypersonic vehicle has important strategic value, but it is difficult to carry out the whole flight test and the flight envelope of the real flight test, simulation-based virtual flight test is its overall performance analysis and verification of the necessary means. Aiming at the multi-disciplinary and multiphysics strong coupling characteristics of hypersonic vehicle in the process of flight, such as overall, control, aerodynamic, structural, dynamic, load, heat and thermal environment, aircraft kinematics and dynamics, Multi-physics coupled virtual flight test platform architecture, a multiphysics coupled virtual simulation test model for the hypersonic vehicle is established, and a multi-disciplinary integrated virtual flight test system based on a high-performance heterogeneous computing system is developed. In order to realize the overall hypersonic vehicle Design provides a reliable and practical way to verify.
