| 摘 要： | 建立了一个具有升力体气动外形飞行器的运动方程，并把飞行器的推重比和其升阻比、发射角以及起飞加速度的函数关系建立了起来。利用这些关系分析的结论是：垂直起飞的推重比必须达到1．3左右，它只适合多级火箭的发射；水平起飞的单级入轨运输器由于升力体效应把推重比 控制0．65左右，适合单级入轨运输器的发射。

| Abstract: | The kinematic equation of the vehicle,which has the aerodynamic shape of the lifting body,has derived and obtained the functional relation of the vehicle thrust/weight ratio with the launch angle,L/D and launch acceleration.Though analysing,author come to the conclusion that the thrust/weight ration must be 1.3,which only suit to launch the multistage rocket.Effecting by the lifting body, when horizontally take off the single stage to orbit vehicle,the thrust/weight ratio would contorl in 0.65. |
