The horizontal take-off and horizontal landing (HTHL) aerospace vehicle is an important means for future space rapid response and low-cost space transportation. Combined cycle power has full envelope flight capability, and uses air as an oxidant in the atmosphere to greatly enhance the specific impulse of the engine. Therefore, it is the preferred engine system for future HTHL aerospace vehicle. This paper reviews the development history and status of the combined cycle powered aerospace vehicles at home and abroad, and describes the advantages and disadvantages of various types of takeoff and landing. The advantages of HTHL and the requirements for the vehicle and engine are clarified. By comparison of RBCC and rocket for aerospace vehicle, the application advantage of combined cycle engine in HTHL aerospace vehicle is confirmed.
