摘　　要：利用典型状态的风洞试验结果对十字布局与叉字布局再入机动飞行器的气动特性进行了分析与比较。研究结果表明 ,叉字布局的静稳定裕度变化范围大于十字布局 ,机动配平能力高于十字布局 ,升力、升阻比与十字布局相当 ,舵面控制效率大于十字布局 ,舵前缘压力与十字布局相当 ,舵面压力则远大于十字布局 ,俯仰、偏航、滚转控制的气动交连耦合影响比十字布局严重。In this paper aerodynamic characteristics of maneuvering reentry vehicle of cruciform configuration and bifurcate configuration are compared by means of the wind tunnel test results. The present work results show that the static stability,trimming ability,control surface efficiency of the reentry vehicle of bifurcate configuration are higher in comparison with those of the reentry vehicle of cruciform configuration, the lift force,lift drag ratio and pressure of leading edge are equivalent to those of cruciform configuration, the pressure of control surface is much higher than that of cruciform configuration and the coupling interaction of pitch,yaw and roll is larger than that of cruciform configuration.
