Aero-engine bleed air test equipment and test method

Abstract

The invention relates to aero-engine bleed air test equipment and a test method, and aims to solve the problems that traditional APS bleed air test equipment cannot accurately measure important process parameters such as bleed air temperature, pressure and flow in a starting test process, cannot simulate an environment control bleed air system load to carry out a dynamic test, and does not have other air source interfaces. The equipment comprises an APU bleed air output pipeline, a flow monitoring pipeline, an ATS bleed air input pipeline, an environmental control bleed air pipeline, a bidirectional conveying pipeline, a bidirectional switching pipeline, an exhaust pipeline, an exhaust tower, a first air source output pipeline and a second air source output pipeline. The environment control air entraining pipeline can realize the load test of the environment control air entraining system; a probe and a flowmeter are arranged on each pipeline, so that key process parameters such as bleed air flow, temperature and pressure in the test can be accurately measured; and the first gas source output pipeline and the second gas source output pipeline can support gas supply of various gas sources.

Description

technical field [0001] The invention relates to the field of aero-engine tests, in particular to an aero-engine bleed air test device and a test method. Background technique [0002] In the starting test of the aircraft auxiliary power system (APS, Auxiliary Power System), the bleed air flow output by the auxiliary power unit (APU) is delivered to the air turbine starter (ATS) installed on the aircraft attachment casing (AMAD), and the turbine The output shaft power is impacted by the airflow, which drives the fly-attached casing to run and then realizes the starting of the main engine. During the start-up process of APS, the temperature, pressure and flow rate of bleed air are important parameters in the test process. [0003] The traditional APS bleed air test equipment can only realize the APU bleed air is directly transported to the ATS through the pipeline for start-up test, and cannot accurately measure important process parameters such as bleed air temperature, press...
