Rapid Decompression Test Chamber

CSZ’s rapid decompression test chamber is designed to simulate rapid decompression for testing aircraft avionics. The environmental chamber meets the environmental conditions and test procedures for airborne equipment referenced in the RTCA DO-160 test specification.

The DO-160 specification was designed to test sudden pressure changes starting from 8,000 feet to 60,000 feet in 15 seconds. An altitude of 8,000 feet was used for the initial cabin altitude and 60,000 feet was used for the final cabin altitude after decompression. This test specification is used to identify failures of materials inside of the cabin and the reaction to the surrounding environment.

To meet the test requirements of the customer, CSZ designed and manufactured a customized altitude chamber. A large vacuum pump was incorporated in the design along with various control valves operated by the CSZ EZT programmable controller. Control mechanisms were used to insure minimal overshoot during rapid evacuation and tight control after stabilization at any altitude set point within the full-specified range.
