The invention provides a high-speed motor train unit laser resistance reduction device and a resistance reduction method thereof.The high-speed motor train unit laser resistance reduction device comprises a motor train unit head and a laser generator, the laser generator comprises a laser emission head and a laser emission head shell, and the laser emission head is arranged on the laser emission head shell; a plurality of laser transmitter mounting point positions are arranged on a train head of the motor train unit, and the laser transmitters are arranged on the laser transmitter mounting point positions. A laser generating device is embedded near a streamline train body, so that the laser is transmitted by the laser generating device to ionize air at the point positions which are a certain distance away from the train head; therefore, the bow-shaped shock wave surface in front of the vehicle is damaged and is converted into oblique shock waves with relatively weak wave resistance, so that the effects of reducing the wave resistance of the vehicle head and reducing the differential pressure resistance of the vehicle are achieved.

    本发明提供一种高速动车组激光减阻装置及其减阻方法,包括:动车组车头和激光发生器,所述激光发生器包括激光发射头和激光发射头壳体,所述激光发射头设置在所述激光发射头壳体上;所述动车组车头上设有多个激光发射器安装点位,所述激光发射器设置在所述激光发射器安装点位上,本发明主要利用流线型车身附近嵌设激光发生装置,使得其发射激光电离距车头一定距离的点位处的空气,进而破坏车前的弓形激波面,使其转化为波阻较弱的斜激波,从而起到减小车头位置的波阻,降低车辆的压差阻力的效果。
