The invention provides an engine composite energy cascade extraction system and an engine comprising the engine composite energy cascade extraction system.The engine composite energy cascade extraction system is based on a turbojet engine main engine and comprises a rotor shaft, an exhaust nozzle, a first power generation assembly and a second power generation assembly located outside the exhaust nozzle; the first power generation assembly comprises a first generator which is in transmission connection with the rotor shaft; at least one opening is formed in a shell of the exhaust nozzle. The second power generation assembly comprises a rotating device and a second power generator in transmission connection with the rotating device. When the engine composite energy cascade extraction system is in a high-power output working mode, the rotating device communicates with the exhaust nozzle through at least one opening, at least one part of gas in the exhaust nozzle is used for driving the rotating device to rotate
