摘要/Abstract

摘要： 虚拟飞行试验是临近空间飞行器总体性能验证补充手段。多物理场耦合建模仿真的复杂性对虚拟试验精度和效率都形成挑战,已成为系统仿真领域的一个经典问题。基于此,建立了多物理场耦合仿真模型,提出多物理场耦合的高效并行仿真架构和多专业异构CAE模型协同运行方法,研究了任务级、算法级混合大规模并行仿真技术,构建了基于高性能计算机（High performance computer,HPC）的虚拟飞行试验系统（Flight system testbed,FST）,显著提高了虚拟飞行试验效率,对飞行器总体设计水平的提升具有重要意义。

Abstract: Multidisciplinary simulation based on virtual flight system testbed (FST) will become an alternative way for the overall performance validation of near space hypersonic vehicles (HSV). The complexity of multi-physical field coupled modeling and simulation challenges the accuracy and efficiency of virtual experiment. Therefore, a multi-physical-field coupling simulation model is established. The architecture of HPC-FST is explicitly expounded for large-scale parallel multidisciplinary virtual flight tests and multi-physics coupling simulation of whole vehicle. Moreover, an integration algorithm is developed for heterogeneous CAE models in collaborative simulation. A HPC based parallel virtual flight test method with a task-level and algorithm-level hybrid large-scale parallel simulation technology is developed for whole flight envelope simulation, and a large-scale parallel simulation algorithm is proposed for efficient simulation of aerodynamic flow field. Based on the supercomputer, HPC-FST is a high efficient platform for overall performance validation of HSV, which will reduce development cost as well as improve integrated design capability.

Key words: virtual flight system testbed, near space vehicle, multi-physical coupling, high performance computing, overall performance
