飞机的螺旋桨 meaning in Chinese
wind stick
Examples
- The propeller of an airplane forces air backward , developing thrust
飞机的螺旋桨迫使空气向后移动,于是就产生了推力。 - Sometimes , a plane ' s propeller pulled masses of flying insects into the engine
有时，飞机的螺旋桨会把大量的飞虫吸到发动机里。 - An airplane cannot fly out into space be cause it must have the air for its propellers to push against
飞机不能飞入太空，因为飞机的螺旋桨如果没有空气的反推力推进，是飞不起来的。 - A mathematic model of the motor is builded and emulated through matlab . the low - speed and constant - torque , high - speed and constant - power state is analyzed and researched , also the software approach of simulation to the driver has been done , a digital signal processor tms320lf2407 is developed successfully to control the perm square - wave bldcm driving airscrew of solar powered unmanned engine . it is useful to the further study
在matlab下建立了电机的数学模型，通过计算机仿真，验证了数学模型的正确性，同时在理论上对低速恒转矩高速恒功率运行进行了分析与研究，提出了一种用模糊控制的方法实现恒功率控制，并对驱动器进行了系统仿真，成功的研制了以数字信号处理控制器tms320lf2407为控制核心的驱动器，控制无刷直流电动机驱动太阳能无人飞机的螺旋桨，为后面继续研究工作提供了参考。
