The jet flow resistance reduction technology utilizes the jet flow entrainment effect of compressed air to weaken airflow flowing around a vehicle, negative pressure is formed on the surface of the vehicle, when air on the surface of the vehicle is completely entrainment taken away, the vehicle runs at a high speed, no airflow flowing around the vehicle exists, and the vehicle equivalently runs in a vacuum pipe. And the vehicle can run at the lowest energy consumption and the highest speed without being influenced by any airflow (including transverse wind). In practical application, the jet pipe can form a certain inclined angle with the surface of a vehicle, and compressed air is jetted towards the rear of the driving direction of the vehicle, so that certain thrust is generated, and the driving energy consumption of the vehicle is reduced. According to the jet flow resistance reduction technology, the effect that a vehicle runs at a high speed in a virtual vacuum tube can be achieved theoretically, but actually, according to different types of applied vehicles, through reasonable design, only the partial jet flow resistance reduction effect needs to be achieved, and complete absolute vacuum is not achieved.

    射流减阻技术利用压缩空气的射流卷吸作用,使车辆绕流流动的气流减弱,在车辆表面形成负压,当车辆表面空气被完全卷吸带走时,车辆以高速行驶,车辆周围无绕流流动的气流,车辆相当于在一个真空管中穿行,完全不受任何气流(包括横向风)的影响,车辆可以以最低的能耗和最高的速度行驶。实际应用时,射流管与车辆表面可成一定倾斜角度,压缩空气向车辆行驶方向后方喷出,从而产生一定的推力,有助于减少车辆行驶能耗。射流减阻技术从理论上可以使车辆达到在一条虚拟真空管中高速行驶的效果,但实际上根据应用车辆类型的不同,通过合理设计,只须取得部分射流减阻效果,并非完全绝对真空。
