摘　　要：航天领域的大规模科学与工程问题的数值模拟既依赖于高性能并行计算的支撑,同时也是高性能并行计算发展的动力。综述了航天领域高性能并行计算的研究进展,对高性能并行计算环境进行简单介绍,对相关研究领域包括气动力、气动热、化学非平衡、结构强度、热防护、蒙特卡罗方法和湍流研究等进行分类和详细阐述;总结了航天领域高性能并行计算存在科学计算高并行效率和工程计算低实用价值、并行应用的多样性和缺少科学的并行方法的矛盾,并指出了进一步研究方向。The numerical simulation of the large scale science and engineering problem in the aero- space area relies on the support of High-Performance Parallel Computing （HPPC） and is the engine of the development of HPPC. The paper gives a survey of recent progress of HPPC in the aerospace area and a brief introduction of the HPPC environment. The relative research areas of HPPC of aerospace, including aerodynamic, aerothermal, chemical non-equilibrium, structure, heat protection, Monte Carlo method and turbulence et al. , are classified and described in detail. The dilemma of high parallel efficiency in scientific computing and low use in engineering computing, and the diversity of parallel applications and the lack of scientific parallel methods are concluded. Finally, the prospects of the future HPPC development in aerospace area are presented.
