- 摘要:
- 具有多种工作模态是RBCC动力系统区别于其他发动机的重要特性。灵活运用不同模态和发动机构型,形成不同方案的RBCC动力系统,满足特定的飞行任务,是RBCC动力系统研发的重要思路。模态间的平稳过渡是确保飞行器经济、安全工作的基本条件。深入研究各模态特性、模态转换中的技术问题及解决途径是RBCC动力系统研发的重要技术基础,对指导和引领当前的关键技术攻关也有着重要作用。RBCC动力系统研发的宗旨在于发挥火箭发动机和冲压发动机的优势,弥补单一发动机功能或者性能的不足,突破点在于国家急需与当今技术成熟度的结合。
- Abstract:
- The manifold work modal of the rocket based combined cycle (RBCC) power system is its leading difference from other power engines. The RBCC power system solution formed by different work modal and engine configuration is the developmental route of RBCC power system, which can satisfy the needs of specific flight mission. The smooth conversion of diverse work modals is the essential need of spacecraft safe work. The intensive research of modal characteristics, technical issues in modal conversion and resolving method is the base of RBCC power system development, and has the important function of shepherding the key technique development. The purpose of developing RBCC power system is to make full use of the advantages of ramjet and rocket engine, remedy the function disfigurement and performance deficiency of LRE or ramjet. The way rests with combination of ripe technology and national demand.
