摘　　要：开展升力体运载器的气动布局概念设计研究,利用二次曲线横截面及模线设计方法,提出一种类X-38升力体运载器气动外形,进行机体的优化和控制舵的匹配设计,研究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,有较高的容积效率和机动控制效率,可以作为未来航天运载器的潜在可行方案。The aerodynamic configuration conceptual design of a lifting body transporter is investigated.A X-38 analog lifting body transporter configuration is proposed via biconic cross section design method and Spline Lofting design process.The main body is optimized,the stabilizers and control surfaces,such as V-shape vertical tails,rudders,body flaps and elevons are designed and matched,and the aerodynamic characteristics and the control efficiency are studied.The detail research indicated that the proposed lifting body transporter has a relative high hypersonic lift to drag ratio,high trimming angle of attack and big volume utility ratio,the hypersonic stability derivatives predicted by the engineering model developed from Embedded Newtonian Flow Theory shown that the transporter is static and dynamic stable in both lateral and directional directions at high trimming angle of attack.The present work focus on the conceptual design method,the proposed X-38 analog lifting body is one of the feasible transporter choice.
