Introduction:
Explosive depressurization refers to the intense depressurization process that occurs in the crew cabin of an aircraft. It is usually caused by damage to the crew cabin of the aircraft or rapid air leakage. Conventionally, the depressurization rate at which the altitude increase rate of the crew cabin exceeds 1.5km/s corresponding to a sudden drop in pressure is defined as explosive depressurization.
A sudden cabin leak poses a severe threat to life without protective measures, causing critical oxygen deprivation in the body that can lead to death within a short period. To prevent depressurization sickness at high altitudes, therefore, pilots should be equipped with pressurized oxygen gear appropriate for the altitude. The apparatus used to conduct this transient simulation experiment is known as a high-altitude explosion depressurization test device.
Functions:
1) Altitude Simulation: Altitude simulation refers to the actual altitude at which aircraft and fighter jets operate. Vacuum simulation is used to simulate the flight altitudes of airplanes and fighter jets.
2) Depressurization equilibrium time: This is a critical technical parameter for explosive pressurization simulation equipment. In modern high-altitude fighter aircraft, when the entire canopy is blown off, the equilibrium time can reach 0.05 seconds. Therefore, the depressurization rate of the explosive depressurization chamber is approximately 0.1 to 1 second.
3) Oxygen Supply System: Sufficient oxygen is provided to crew members inside the crew cabin during depressurization to ensure their safety.
Parameters:
1) Depressurization altitude: 0–40 km
2) Depressurization time: 0.1–1 s (adjustable)
3) Vacuum pumping time: ≤1 hour
4) Oxygen Supply System: Oxygen supply pressure: 0–0.6 MPa (adjustable); flow rate: ≥350 L/min
(All parameters above can be customized to meet specific user requirements.)
