摘要
本文计算和分析了弯体机动再入飞行器的高超声速纵横向气动特性。研究了质心布置对配平、配平升阻比的影响规律，给出了三个方向稳定配平的必要充分条件。通过气动力与六自由度弹道的耦合，模拟了弯体飞行器螺旋机动飞行时的弹道特性。
Hypersonic characteristics of bented maneuvering reentry vehicle were calculated and analysed. Effects of location of center of gravity on trimming angle of attack were studied. Essential and sufficient conditions of steady trimming about three directions were presented. Trajectory of spiral flight was imitated by the coupling calculation program of aerodynamic and six dimension trajectory equations. The most important key for a successful design is the control of crosswise movement of the gravity center.
