A pressure imbalance emergency treatment system for aircraft testing and its treatment method

Abstract

The invention discloses a pressure unbalance emergency treatment system for aircraft testing and a treatment method thereof, belonging to the technical field of aircraft testing. The treatment system includes a thermal insulation sealing plate, a driving component, a sealing component, a shock absorption component and a PLC controller, and the thermal insulation sealing plate is hinged. Inside the fire escape, the driving assembly includes a first hydraulic rod and a second hydraulic rod. One end of the first hydraulic rod is hinged with the fire escape, and the other end is hinged with the heat preservation sealing plate. The second hydraulic rod is located at the bottom of the fire escape and sealed with the heat preservation. The plates are connected flexibly; the sealing assembly includes an electric heating plate and a sealing strip. The electric heating plate is set on the side wall of the heat preservation sealing plate, and the sealing strip is set outside the electric heating plate; The vibration generated when the board descends; the PLC controller is electrically connected with each electrical equipment respectively; the system structure design of the present invention is reasonable, and the thermal insulation and sealing board responds quickly, which is beneficial to improving the safety and reliability of the aircraft test work.

Description

technical field [0001] The invention relates to the technical field of aircraft testing, in particular to a pressure imbalance emergency processing system for aircraft testing and a processing method thereof. Background technique [0002] As a large-scale carrying facility for aircraft environmental testing, the climate environment laboratory can accommodate full-scale aircraft and provide all-weather, time-limited high temperature, low temperature and other environmental conditions. The engine start-up environment simulation is to simulate the low temperature, high temperature, damp heat and other climatic environments encountered during the startup or operation of the aircraft engine in the climate environment laboratory. The environmental laboratory must be equipped with an air compensation system and an exhaust gas emission system. Due to the huge amount of air consumed during the ground driving test in the engine laboratory. If there is a delay in the dynamic response ...

AI Technical Summary

Problems solved by technology

If there is a delay in the dynamic response of the laboratory air compensation system relative to the change of engine air intake during the engine start-up process, it will cause a large change in the indoor pressure in a short period of time, and the indoor and outdoor pressure difference exceeds the allowable value of the building design. The test environment has adverse effects, damages the laboratory building structure, and threatens the safety of personnel, test pieces and equipment

[0003] At the same time, because the test aircraft is stored in an extreme climate environment, its aircraft fuel, hydraulic oil, and lubricating oil are likely to leak and volatilize.

The climate and environment laboratory is a confined space, where leakage and volatilization lead to an increase in the concentration of oil and gas, and there is a risk of flash explosion or fire

Moreover, due to the requirements of the engine start-up test, the test aircraft carries a large amount of fuel, which further aggravates the risk and poses a serious threat to the safety of the entire laboratory
