description The invention provides a variable cycle compression system performance characterization method. The method comprises the steps that a plane coordinate system with conversion flow of a variable cycle compression system as an abscissa and characteristic parameters of an adjustable duct of the variable cycle compression system as an ordinate is constructed; and in the plane-coordinate system, representing the values of the characteristic parameters in a predetermined mode so as to obtain a variable cycle compression component performance representation schematic diagram based on the surface domain characteristics, which is used for representing the performance of the variable cycle compression system. According to the characterization method provided by the invention, the change rule of performance parameters such as the surge boundary, the working point performance (flow, pressure ratio and efficiency), the highest pressure ratio, the highest efficiency and the like of the self-adaptive three-duct fan/variable-
