Practical Measures for Raising Propeller Efficiency of Low Speed Mini UAV

提高小型无人机螺旋桨效率的工程方法

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.

认为以满足螺旋桨额定推力为目的，推进电动机只需要低速输出额定转矩来实现，即输出功率较低。

But this mystery would inevitably be cleared up, and soon, because Captain Nemo gave orders to increase speed; at once the engine stepped up its drive power, setting the propeller in swifter rotation.

此外，这个神秘必须弄清楚，并且要很快弄清楚，因为船上得到尼摩船长的命令，机器增加推动力，机器转动更快了。

Henry pushed at a lever; there was a click. Slowly at first, then faster and faster, till it was a circular mist before their eyes, the propeller in front of them began to revolve.The wind of a horizontal speed whistled ever more shrilly in the stays.

亨利推了一根杠杆，咋的一声，他们前面的螺旋桨开始了旋转。起初很缓慢，渐渐变快，最后眼前便成了一片圆形的光雾，悬浮平飞的高速风叫得越发尖利了。

The foreign trade is being considered an exogenous factor of economic growth all through the ages, it has always played an important role of a propeller in review of those countries and regions that have fulfilled the economic growth with high speed.

对外贸易历来被认为是经济增长的外部因素，对于推动一个国家或地区的经济增长具有加速器的作用。

Water jet propulsion, widely used in the area of fast-speed ships nowadays, has increasingly taken the place of traditional propeller.

如今在高速船舶领域，喷水推进装置正被广泛的应用，在很大程度上取代了传统的螺旋桨驱动方式。

The ships maintain or change course and speed by using propeller thrust force and rudder strength.

船舶是借助螺旋桨的推力和舵力来保持或改变航向和航速的。

at last, the validity of the speed control performance of propulsion motor with propeller load is verified by simulation.

最后，结合电力推进系统中螺旋桨负载特性对推进电机的调速性能进行了仿真。
