摘要

开展高超声速机动飞行器的气动布局概念设计研究,提出一种新的升力体机动飞行器气动布局方案,进行了机体的优化设计,并进行了控制舵的匹配设计,研究了飞行器的气动特性和操纵效率问题.研究表明,该方案可以获得较高的配平升阻比及配平攻角,有较高的机动控制效率,是高超声速飞行器实现高机动的潜在可行方案.%The aerodynamic configuration conceptional design of a hypersonic maneuvering vehicle is invesitigated.A new aerodynamic configuration scheme of lift body is presented, the main body optimized, the control flaps matched, and the aerodynamic characteristics and the control efficiency are studied.The design and analysis methods adopted includes geometry parametric method basied on Lofting method and conic cross secetion description, engineering aerodynamic prediction method based on Newtonian flow, and multi-objective optimization method.The detail research indicated that the proposed lift body configuration has a wide trimming range of AOA from 0° to bigger than 40°, the maximum hypersonic trimming lift to drag ratio is higher than 2.0, and the stability and trimming capibility are within a reasonable range.The present work focus on the conceptional design method and the proposed lift body is one of the potential hypersonic manervers.
