摘　　要：开展升力体运载器的气动布局概念设计研究及气动操稳特性分析。利用二次曲线横截面、指数函数纵向控制线及模线设计方法,提出一种类X-33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、纵横向稳定性问题和操纵效率问题。研究表明,方案具备较高的高超声速配平升阻比,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,controllability and stability of a lifting body transporter are investigated.A X-33analog lifting body transporter configuration is proposed via biconic cross section design method,exponential function longitudinal control and spline lofting design process.The main body is optimized,the control surfaces,include tail and rudders,canted fin and ailerons,bodyflap and elevons,are designed and matched,and the aerodynamic characteristics,longitudinal and lateral control stability 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,big volume utility ratio and maneuver control efficiency.The transporter is directional unstable but longitudinal and lateral static stable at medium angle of attack.To steer the vehicle directionally,rudders within medium AOA and ailerons at high AOA are suggested,and the roll movement induced by rudders and ailerons can be controlled by elevons differential deflection.The present work focus on the conceptual design method,the proposed X-33analog lifting body is one of the feasible transporter choices.
