subsonic combustion meaning in Chinese

亚音速燃烧

Both advantages of rocket engine and air - breathing engine are integrated into one kind of propulsion system , called rocket - based - combined - cycle ( rbcc ) , which has multiple operating woke modes , including ejecting , subsonic combustion , supersonic combustion and rocket mode , with each mode operating at varying flying stage . rbcc has prominent potential of high efficiency and low cost , and so it is recognized as an advanced propulsion system of future single - stage - to - orbit reusable spacecraft and hipper - sonic missile . it has been broadly investigated in foreign countries and has been progressed into small and full - scale flying stage
火箭基组合动力循环( rbcc ， rocketbasedcombinedcycle )将传统的火箭发动机和吸气式发动机的优点集中组合到一个具有多种工作模态(包括引射、亚燃、超燃及火箭模态)的发动机里，在不同的飞行阶段启用不同的工作模态，因此具有大幅提高航天推进系统经济性与高效性的潜在优势，并可能发展成为下一代单级可重复使用航天器以及高超声速导弹武器的动力系统。
