The invention provides a combined type rocket engine. The combined type rocket engine comprises a shell, a fixed guiding column, a detonation engine body, an outer air inlet duct, a second combustion chamber and a solid grain. According to the combined type rocket engine, the detonation engine body and the solid grain are integrated in the shell, generated propelling force can be greatly increased by means of high-temperature fuel gas generated through combustion of fuel in the detonation engine body and the combustion of the solid grain, and thus the thermodynamic efficiency of the combined type rocket engine and the performance of a power system are improved; the detonation engine body is arranged at the front end of the shell, the size of a first combustion chamber is reduced, internal space is saved, and the structure of the combine type rocket engine is simplified; saved internal space can be used for increasing the size of the solid grain, and thus the performance of the power system of the combined type rocket engine is improved; after the solid grain is burnt off, non-burnt fuel in the high-temperature fuel gas sprayed out from an outlet of the shell reacts with air flowing in through the outer air inlet duct to be burnt, so that propelling force is generated, waste of the fuel gas is avoided, and the economic performance of the combined type rocket engine is improved.
Description
technical field [0001] The invention relates to the field of engines, in particular to a combined rocket engine. Background technique [0002] In recent years, with the continuous deepening of research on hypersonic vehicles and single-stage orbital power systems, the technology of air-breathing combined cycle engines has developed rapidly, especially for rocket-based combined cycle engines and turbine-based combined cycle engines. In-depth research, since the 1980s, research on related application technologies has begun. Among them, the rocket-based combined cycle engine is a combined engine that effectively combines the rocket and the ramjet engine, and under different working conditions, the two different engines can give full play to their respective maximum performance advantages, thus successfully realizing aerospace power propulsion. best combination. The turbine-based combined cycle engine is a combined engine that effectively combines a turbine engine and a ramjet...
