Abstract

Auxiliary Power unit Systems (APS) are widely used in civil aircraft to provide air and power. APS is an air-breathing power system, and its intake system at the front end of the system cycle has a very important impact on the overall performance. Through the geometric modeling of the APS intake system, three-dimensional fluid simulation calculations are carried out to study the influence of the inlet door angle on the intake aerodynamic performance. As the angle of inlet door increases, whether on the ground or in the air, the average total pressure at the outlet of the inlet duct increases, the total pressure loss decreases, the ram recovery coefficient becomes larger, and the intake aerodynamic performance is better, which is beneficial to the APS system performance. This phenomenon is more obvious in air conditions.
