Abstract

The design of modern civil aircraft systems pays great attention to its economy. Auxiliary power unit systems (APS) is used continuously while waiting for passengers on the ground, and the market demands for its performance and fuel consumption gradually improve. The APS performance of APS is greatly affected by aerodynamic performance. Referring to the calculation method of aerodynamic theory, a set of methods suitable for the numerical calculation of the aerodynamic performance of APS based on the practice of system design is researched and summarized in this paper. A design example is selected and the method is used to calculate the total pressure loss and ram recovery of aerodynamic performance indicators. The results indicate the ground total pressure loss and air ram recovery under the five working conditions meet the design requirements and close to the simulation results. This provides a reference for the aerodynamic design of APS.
