Abstract

The invention discloses a testing system for an aircraft auxiliary power unit, which comprises a console, an electronic control unit, a fuel tank, a test bench, a vibration sensor, and an auxiliary power unit, wherein the console comprises a program control computer, an electric control box, a fuel control box and an air intake and exhaust oil tank; the test bench mainly comprises a mounting base, a dynamometer system, an exhaust pipeline and a bleeding pipeline; a temperature sensor, a pressure sensor and a gas flowmeter are arranged on the bleeding pipeline; the dynamometer system comprises an eddy current dynamometer and a connection shaft; and the eddy current dynamometer is connected with the auxiliary power unit via the connection shaft. Vacancy of domestic aircraft auxiliary power unit testing devices is remedied, the technology blockage in the field by oversea factories is broken, and the flight punctuality rate and the flight safety are ensured. Meanwhile, a large amount of transportation time and detection and maintenance costs are saved for airlines, the real-time performance and the accuracy of the test are ensured, and the labor intensity of a testing operator is lessened.

Description

technical field [0001] The invention relates to the field of aviation testing, in particular to an aircraft auxiliary power unit testing system. Background technique [0002] The aircraft auxiliary power unit (hereinafter referred to as the auxiliary power unit) is an airborne power unit produced by the American HONEYWELL company, which is mainly used to provide power and bleed air for the aircraft when the aircraft is parked. This auxiliary power unit is widely used in small and medium-sized transport aircraft, such as domestic aircraft Xinzhou 60, imported aircraft CRJ models, EMB models, etc. [0003] Auxiliary power unit is a high-tech product, which has high requirements on product reliability and technical indicators. According to the continuous airworthiness requirements of civil aviation regulations, the auxiliary power unit needs to be tested regularly, and it must be repaired and tested to pass the test before it can be installed and used. The inspection and main...
