The invention relates to the technical field of rail traffic, in particular to an upper and lower double-duct jet-propelled pipeline ultra-high-speed galloping vehicle running method and system. During air suction, most incoming flow at a vehicle head in an upper duct is compressed to a lower duct through an air suction channel by a vehicle head propeller of a galloping vehicle; a small part of airflow at the head is compressed to the lower duct through an air suction channel under the action of a guide plate at the galloping body and a propeller of the galloping body; during compression, a propeller at the bottom of the aerodyne compresses airflow into a pressure bin of a lower duct at the lower part of the aerodyne through an air suction channel; during air injection, the dynamic sealing state of the pressure bin of the lower duct located at the tail of the aerodyne is damaged, high-pressure air flow in the lower duct is injected to the upper duct from the air outlet channel along the tail of the aerodyne, the air flow is guided to the tail of the aerodyne body through a propeller at the tail of the aerodyne, and air injection type ultra-high-speed operation of the aerodyne in a pipeline is achieved. The upper duct and the lower duct are constructed in the pipeline, airflow is effectively organized, the running resistance of the galloping vehicle is reduced, and the running efficiency of the ultra-high-speed galloping vehicle is improved.
本发明涉及轨道交通技术领域,尤其涉及一种上下双涵道喷气式管道超高速飞车运行方法及运行系统,吸气时,飞车的车头螺旋桨将上涵道内车头处大部分来流通过吸气通道压缩至下涵道;车头处小部分气流通过飞车车身处导流板以及车身螺旋桨作用通过吸气通道压缩至下涵道;压缩时,飞车的底部螺旋桨将气流通过吸气通道压缩至飞车下部的下涵道的压力仓内;喷气时,位于飞车尾部的下涵道的压力仓动态密封状态被破坏,下涵道内的高压气流从出气通道沿着飞车车尾喷出至上涵道,且飞车的尾部螺旋桨将气流引导至车体尾部,实现飞车在管道内喷气式超高速运行。在管道内部构建上下双涵道,有效组织气流,减小了飞车运行阻力,提高超高速飞车的运行效率。
