Abstract: Integrated design of integral liquid fuel ramjet (ILER) is regarded as a system of the combination of missile and ILFR, which aims at obtaining the optimum performance of the system and optimizing the parameters of both missile and ramjet. In this paper, supersonic cruise missile of medium range is taken as a calculation example. In accordance with the features of integrated ramjet, the integrated design of missile andintegral ramjet are discussed here. Missile configuration and ramjet parameters are optimized and then the maxmum range is obfained based on two typical cases in medium and low height-cruising. Some problems related to choosing missile and ramjet parameters are also discussed and analyzed for application in different cruise heights.
