摘要
随着现代航天、航空技术的发展,传统的化学火箭发动机的比冲已经接近理论极限,为了追求更大比冲而发展的组合循环动力技术可以最大限度发挥不同动力方式的优点,提高动力推进系统性能。通过分析组合循环动力的技术特点及发展现状,研究天地往返领域动力推进系统的发展趋势,并提出相关发展建议。
With the development ＆modern aerospace technology, the specific impulse of traditional chemical thruster has almost reached its theoretical limit. In order to increase the specific impulse of propulsion systems, combined cycle propulsion technology has been widely studied to utilize advantages of different power forms and improve the capability of propulsion systems. After the analysis of technology characteristics and recent development of combined cycle propulsion, the development trend for propulsion systems in the field of reusable launch vehicle is studied, and corresponding suggestions are proposed.
