冲压发动机与喷气发动机相同,由于利用大气中的氧气,因而与火箭发动机相比,可以减少燃料装载量,同等数量的燃料以Ma=2的速度飞行时飞行时间可增加10s以上。按燃烧方式和燃料种类分类,冲压发动机主要可分管道火箭、液体冲压发动机和超燃冲压发动机。为评价冲压发动机的性能,必须模拟发动机在空气中高速飞行的状态。为形成模拟气流必须有冲压发动机燃烧试车台。为此,日产汽车公司宇航事业部在川越建造了一座试车台。 The ramjet engine is the same as a jet engine and uses oxygen in the atmosphere to reduce fuel load compared to a rocket motor, while flying the same amount of fuel at Ma = 2 can increase flight time by more than 10 s. According to the type of combustion and fuel classification, stamping engine can be divided into the main pipeline rocket, liquid ramjet engine and scramjet. In order to evaluate the performance of ramjet engines, it is necessary to simulate the state of the engine flying at high speed in the air. There must be a ramjet test bed to create a simulated airflow. To this end, Nissan Motor Aerospace Division in Sichuan and Vietnam built a test bed.
