The invention discloses a distributed compression and cyclone ramjet engine and aims to solve the problems that an existing ramjet engine cannot start by itself, and can work only by being accelerated to a certain speed by a roll booster, the existing ramjet engine is sensitive to changes in flight states, and when the existing ramjet engine is combined with a turbojet engine or a fanjet to be used as an aero-engine, the beneficial effects that the ramjet engine is simple in structure and the like are lost. The engine comprises turbine systems, a casing, a cyclone generator, a low-temperature heat exchanger, a guide blade, a stamping cone, an intermediate-temperature heat exchanger, a high-temperature heat exchanger and the like. Turbines are heated by heat exchange gas and pushed by cooling circulation, energy of stamping airflow is fully utilized, the circulation efficiency of the engine is effectively improved, cost is reduced, cyclone stamping is utilized, and the problems that the existing ramjet engine cannot be started at a low speed and cannot adapt to various work conditions are solved. The distributed compression and cyclone ramjet engine is ingenious in concept, reasonable in design and capable of achieving static starting of the engine and adapting to various work conditions, and good application prospects are achieved.
