A method for field detection of military aircraft cockpit air conditioning system

Abstract

The invention relates to a military aviation cockpit air adjusting system external field detecting device and method. The military aviation cockpit air adjusting system external field detecting device comprises a power supply module, a power source testing module, a variable resistor, a negative-pressure generation module, an input module, a display module and a control unit. The device has the advantages of being small in size, convenient to carry, easy to use, high in reliability, high in automation degree and the like. The corresponding detecting method has the advantages that steps are clear, fault parts are easy to determine, and the detecting efficiency is high. According to the detecting device and the detecting method, all influence factors in maintaining of front-line or field environments of a cockpit air adjusting system are taken into full consideration, and the military aviation cockpit air adjusting system external field detecting device and method are suitable for the fault obviation work of the military aviation cockpit air adjusting system in the front-line or field environments.

Description

technical field [0001] The invention relates to an outfield detection device and a detection method for a cockpit air conditioning system of a military aircraft, and is especially suitable for use in an outfield environment, aiming at parts composed of a turbine speed limit controller, an electric mechanism for a pressure regulating valve, and an electric mechanism for an air distribution valve. A testing device and a testing method for testing a cabin air-conditioning system. Background technique [0002] According to statistics, the failure rate of the environmental control system of military aircraft is relatively high, and as the service life of the aircraft increases, the probability of failure of the environmental control system tends to increase gradually. The cockpit air conditioning system is one of the important components of the aircraft environmental control system. Its main function is to further cool down and depressurize the air from the bleed air subsystem to...

AI Technical Summary

Problems solved by technology

The turbine speed limit controller is the control mechanism of the cockpit air conditioning system, and the electric mechanism of the pressure regulating valve and the electric mechanism of the air distribution valve are the actuators of the cockpit air conditioning system. They play a decisive role in the adjustment of the cabin temperature. The common Fault phenomena are usually overheating or overcooling of the cockpit, manual heating or cooling cannot be corrected, overheating of the air supply, and screams or abnormal smells may be accompanied by overheating of the cockpit, which seriously affects the pilot's mental state and Physical and mental health, involving the pilot's energy and restricting the stable performance of the pilot's control of the aircraft performance, has become one of the important reasons for inducing flight accidents

[0004] At present, since there is no special cockpit air-conditioning system testing equipment when the aircraft is equipped with troops, when the aircraft fails, the maintenance personnel can only use experience to eliminate it by "swapping parts" in sequence according to the probability of possible failures. Waste maintenance time, reduce maintenance efficiency, and may damage other parts and accessories of the cabin air-conditioning system during the process of changing parts; due to the lack of necessary testing equipment and methods, this makes it impossible for maintenance personnel to characterize the cabin air-conditioning system and quantitative tests, and it is also impossible to perform pre-installation and post-installation calibration and power-on testing on the main parts and accessories of the cockpit air-conditioning system

[0005] To sum up, there is no detection device and detection method suitable for the cockpit air-conditioning system used in the field environment in the prior art, which cannot meet the maintenance requirements of the field when the cockpit air-conditioning system of military aircraft fails
