Abstract: 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
