three-blade propeller

The plane has an open cockpit, propeller powered by a three-cylinder engine made by Czech firm Verner.

这架飞机拥有开放式驾驶舱，螺旋桨由捷克公司Verner制造的三缸引擎提供动力。

The results obtained from the simulation testing by double digital signal processing ( DSP) system confirm that the DTC system fits for synchronous motor with screw propeller by three level inverter and the system operation performance is perfect.

采用双DSP系统对电动机带螺旋桨负载的推进系统进行了半实物仿真，结果表明文中提出的控制策略能对三电平逆变器供电的同步电动机实施高性能的调速控制。
