Abstract: A mixed digit electronic hydromechanical control system was designed for an integrated liquid fuel ramjet engine. The control plan, the operating principle and the operating mode of the control system were introduced. A hardware in the loop simulation system was composed of the mixed digit electronic hydromechanical control system and an integrative digit simulator of a liquid fuel ramjet engine and missile body. The control function and the operating harmony of the control system were checked. The results of hardware in the loop experiment verified that the requirement for a control system design was satisfied.
