Interference of propeller slipstream, changing of propellerthrust and twist with different flight state was took into account.
在建模过程中，考虑了螺旋桨滑流对飞机的气动干扰及不同飞行状态下螺旋桨拉力及扭矩的变化。

These expressions are suitable for calculating the value of the propellerthrust with computer and convenient for the study of the ship 's maneuverability.
所得的回归表达式适用于计算机进行螺旋桨的进、倒车推(拉)力计算，同时便于进行船舶操纵性研究。

In order to satisfy the operation requirement of the rated thrust of the propeller, the propulsion motor performs only in rated torque on the low speed, so the motor power is low.
