深冷涡喷火箭组合循环发动机初步分析

为了对国外近年来提出的ＫＬＩＮ循环发动机（深冷涡喷发动机ＤＣＴＪ＋火箭发动机ＬＲＥ）的可实现性进行分析验证，估算了深冷涡喷／火箭组合循环发动机的特性，结合国外文献的研究，认为ＫＬＩＮ循环发动机有效载荷系数高、循环效率高、发展风险小、技术上可近期实现，极具开发和应用前景。

Primary analysis of deep cooled turbojet liquid rocket engine combined cycle

In order to verify the realization possibility of the combined propulsion known as KLIN cycle,which consist of a thermally integrated deep cooled turbojet and liquid rocket engine,a primary performance assess was performed From the assessed results and the references, it can be concluded that the KLIN cycle provides a high payload capability of the launcher, and it can be realized in the near term without a need for large leaps in technology Furthermore, KLIN cycle technology is full within current industrial capability and can be completely ground tested, thereby minimizing development risk and cost
