AI Technical Summary

Problems solved by technology

[0003] At present, the existing aircraft generator test system in China generally uses traditional instruments and manual control equipment to complete the generator experiment process, which cannot detect CSD and IDG, and the technical means are backward, and cannot record the dynamic process of relevant parameters during the experiment process. The performance evaluation of the whole machine is not comprehensive enough

Embodiment Construction

[0017] Such as figure 1 As shown, the present invention consists of a prime mover 1, a torque speed sensor 2, a high-speed gearbox 3, an oil station 4, an aircraft constant speed transmission device and a generator 5 or an integrated drive generator 6, a lubricating oil system 7, an excitation control system 8, Loading system 9 and parameter detection system 10. The prime mover 1 is a DC motor, which can provide 250kW power for the tested part. The signal of the torque speed sensor 2 outputs two signals, one electrical signal will detect the rotating speed of the original motor and send it to the parameter detection system 10, the output shaft is connected to the high-speed gearbox 3, and the high-speed gearbox 3 adopts a 5:1 speed-up ratio, Since the maximum speed of the prime mover 1 is 2000rpm, the maximum speed of the output shaft through the high-speed gearbox 3 can reach 10000rpm / min, and the output analog high-speed speed of the high-speed gearbox 3 is respectively conn...

Abstract

The detection system is composed of prime motor, torque rotating speed transducer for detection of torque and prime motor rotating speed, high speed gear box, oil station for providing lubrication and cooling to high speed gear box, airplane constant transmission device IDG, integrated driving generator or generator, lubrication oil system injecting oil to CSD or IDG oil box, excitation control system for controlling and regulating output voltage of motor, loading system and parameter automatic detection system.

Description

technical field [0001] The invention relates to a detection system for an aircraft constant speed transmission, an integrated drive generator or a generator. Background technique [0002] Aircraft constant speed transmission CSD (Constant Speed ​​Device) and integrated drive generator IDG (Integrated Drive Generator) or generator is the main part of the aircraft power supply system, providing 400Hz, 115V / 200V three-phase alternating current, for the aircraft instrumentation, radar , radio communications and various controls and lighting on the aircraft to provide power. According to aviation airworthiness standards, it should be maintained and repaired regularly and irregularly. As the detection system for the ground simulation test, according to the CSD / IDG detection standard, the various states of the CSD / IDG during the flight are simulated by the test bench to detect whether its performance indicators are qualified. [0003] At present, the existing aircraft generator t...
