The invention belongs to the field of aero-engine design, and relates to a method for accurately determining the low conduction capacity requirement of a complete engine, which comprises the following steps of: firstly, respectively carrying out part test, core engine and complete engine test on the engine by adopting the same set of hardware and the same set of test scheme to obtain the actual performance of each part under the overall condition; then, the high-pressure turbine expansion ratio and the external and internal culvert outlet pressure ratio are determined, the subsequent design direction is determined by judging the high-pressure turbine expansion ratio and the expansion ratio design value and the external and internal culvert outlet pressure ratio and the pressure ratio design value respectively, and then the influence of low-pressure turbine guider area adjustment on adjustable parameters is scored, so that the design direction is determined. According to the method, the ...
