摘要
吸气式高超声速飞机面临严酷的高动压、大热流飞行环境,要求机载系统既要兼具高功率、高效能与高耐热能力,又要满足严苛的体积、重量(质量)与能量约束,给飞控作动系统设计带来了极大的技术挑战。本文通过对高超声速飞机任务和平台动力特点的分析,系统地论述了其飞控作动系统面临的挑战,包括能源、结构和热管理等问题。基于已有高速飞机的公开资料,对作动技术发展现状进行了梳理,结合热管理与机载能源的发展趋势,展望了高超声速飞机作动系统的重点发展方向,并给出了具有可行性的发展路线。
The high speed and high dynamic pressure of the air-breathing hypersonic aircraft put forward high requirements on the accuracy and power of the actuation system.The strict volume,weight,energy and heat constraints have brought great difficulties to the design of the actuation system.Based on the analysis on the hypersonic aircraft mission and platform,this paper systematically discusses the technical challenges of the flight control actuation system,especially on the issues of energy,structure and thermal management.Based on the released information,the state of the art of the high speed aircraft actuation technology development is summarized.The technical development emphases of hypersonic aircraft actuation system are prospected,and the feasible technical routes are given.
