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.
