The invention relates to the technical field of communication and transportation, in particular to a hydrogen fuel electric and jet composite propulsion system and method for a high-speed pipeline galloping vehicle, a hydrogen fuel cell is used for providing energy needed by system operation, when the high-speed galloping vehicle runs at the speed close to the sound speed, a turbofan sucks a large amount of air, a vacuum area is formed at the front end of a vehicle body, and the high-speed pipeline galloping vehicle runs in the vacuum area. The pipeline choking effect when the vehicle body runs at a high speed is reduced; a large amount of air sucked by the turbofan enters the pressure chamber at the front end below the vehicle body through the air inlet channel and the airflow channel, and the high-speed galloping vehicle is suspended under the pressure formed by high-pressure air in the pressure chamber below the vehicle body; when the vehicle body continues to move forwards and is located on the upper portion of the flow guide groove of the streamline baffle, high-pressure gas in the pressure chamber at the rear end of the lower portion of the vehicle body is exhausted upwards and forwards through the airflow channel, and the exhausted gas exerts the forward thrust effect on the vehicle body. By means of the composite propelling system and method, formation of turbulent flow at the tail of the vehicle body can be effectively reduced, the air flow field in the pipeline during running of the high-speed galloping vehicle is improved, energy dissipation is reduced, and the running efficiency of the high-speed galloping vehicle is improved.
本发明涉及交通运输技术领域,尤其涉及一种高速管道飞车的氢燃料电动与喷气复合推进系统及方法,使用氢燃料电池提供系统运行所需能量,当高速飞车在接近音速运行时,涡轮风扇吸入大量空气,并在车体前端形成真空区域,降低车体高速运行时受到的管道壅塞效应;所述涡轮风扇吸入的大量空气通过进气道以及气流通道进入车体下方前端的压力舱内,车体下方压力舱中的高压气体所形成的压力使得高速飞车悬浮;当车体继续向前运行,且车体位于流线型挡板的导流槽上部时,车体下方后端的压力舱的高压气体通过气流通道向上且向前排出,排出的气体给予车体向前的推力作用。用所述复合推进系统及方法,可以有效减少车体尾部湍流流动的形成,改善管道内高速飞车运行时的空气流场,减少能量耗散,提高高速飞车运行效率。
