摘要/Abstract

摘要： C-HGB （Common Hypersonic Glide Body）作为美国现今试验成功率最高的高超声速滑翔飞行器已被美国防部列入重点发展项目，并预计发展为三军通用武器。本文针对此类"球+双锥+弹翼"的气动外形和隐身性能进行了研究。采用考虑交互作用的正交设计进行了多约束下参数敏感性分析，并采用改进的基于DE差分变异算子的具有自适应学习机制的优化算法进行气动优化，对优化后的外形采用简单高效的锐边化设计，在提高升阻比的同时可降低雷达散射截面积，极大提高突防能力。锐边设计改变了弹体部分表面温度分布，降低制造成本的同时对热防护系统的设计和红外隐身具有一定积极意义。结果表明：锐边化设计可以得到较好的气动隐身性能，是未来高超声速滑翔飞行器的潜在设计方案。

Abstract: As the hypersonic glider with the highest test success rate in the United States, C-HGB (Common Hypersonic Glide Body) has been listed as a key development project by the U.S. Department of Defense, and is expected to develop into a common weapon of the three services. In this paper, the aerodynamic shape and stealth performance of this kind of "ball + biconical + wing" are studied. The orthogonal design considering interaction is used to analyze the parameter sensitivity under multiple constraints, and the improved optimization algorithm with adaptive learning mechanism based on de difference mutation operator is used for aerodynamic optimization. The optimized shape adopts the simple and efficient sharp edge design, which can not only improve the lift drag ratio, but also reduce the radar scattering cross-sectional area and greatly improve the penetration ability. The sharp edge design changes the surface temperature distribution of the projectile, reduces the manufacturing cost, and has positive significance for the design of thermal protection system and infrared stealth. The results show that the sharp edge design can obtain better aerodynamic stealth performance, and is a potential design scheme of hypersonic glider in the future.

Key words: C-HGB, sharp edged, aerodynamic stealth, orthogonal optimization, optimization design
