The transition equipment is an important constituent part of integrated rocket ramjet engine, it determines successful transition of the rocket ramjet engine from boosting to mixing combustion. The transition technology of monolithic solid rocket ramjet engine was studied in this paper. The function and design requirements of the transition equipment were definite. Several types of inlet in-take cover or outtake covers and gas generation injecting nozzle covers were introduced emphatically. In addition, the characteristic of every scheme was illustrated. Several methods of simple or system transition confirmatory test and control method of transition time sequence were presented. All these will offer the basis for the research of transition technology.
