This paper presents the development of the liquid propellant rocket engine technology from the viewpoint of combustion chamber pressure, thrustlevel and power cycle.
本文从燃烧室压力、系统工作循环方式以及最大推力三个方面叙述了世界各国液体火箭发动机的技术水平。

It is also seen that the transverse shear deformation and warping have effects on the aeroelastic stability of the rotor blade. These effects become larger at the higher thrustlevel.
同时对悬停时桨叶的气弹稳定性有相当程度的影响，尤其是在高桨距角下这种影响是不能忽略的。
