The invention belongs to the field of variable cycle engine structure design and particularly relates to a compression system of a variable cycle engine. The compression system comprises a shell, a CDFS rotor shaft, a CDFS rotor, a gas compressor second-stage rotor, a transfer disk, three rows of stators, a small duct, a valve, a first driving mechanism and a second driving mechanism, wherein theCDFS rotor shaft is provided with a shaft journal; the CDFS rotor and a first-stage rotor are fixedly arranged at the two ends of the shaft journal correspondingly; the first stator and the second stator are arranged on the axial two sides of the CDFS rotor, and the third stator is arranged between the first-stage rotor and the second-stage rotor; the small duct is formed in the position, betweenthe second stator and the first-stage rotor of the gas compressor, of a shell; the valve is used for controlling the outlet area of the small duct; the first driving mechanism is used for controllingthe valve to move; and the second driving mechanism is used for driving stator blades of the first stator to rotate. The compression system of the variable cycle engine, provided by the invention, canrealize pneumatic distribution of a CDFS and the gas compressor and gas flow distribution of an outlet of the CDFS, change thermodynamic cycle parameters of the engine and realize variable cycle characteristics.
Description
technical field [0001] The application belongs to the field of variable cycle engine structure design, and in particular relates to a compression system of a variable cycle engine. Background technique [0002] The variable cycle engine adjusts the thermodynamic cycle parameters in combination with changes in the geometry, size or position of some components. Compared with the conventional hybrid turbofan engine, the variable cycle engine has better flow matching performance with the intake port, reducing the size of the conventional hybrid turbofan. The overflow resistance and rear body resistance of the engine during the throttling process improve the circulation capacity of the fan, thereby reducing the installation loss of the propulsion system. Core driven fan stage (CDFS for short) and Front Variable Area Bypass Inject (FVABI for short) are the main components of the variable cycle engine compression system. [0003] The existing technical solutions are mostly traditi...
