A Combined Environments Reliability Test (CERT) Facility for Testing of Airborne Equipment

摘要

A third combined environment reliability test facility has been developed with improved capability to simulate the dynamic combined environments that internally carried aircraft equipment is exposed to in modern high performance military aircraft. An electro-pneumatic control system individually controls compartment temperature, humidity, air mass flow and altitude, and equipment cooling air temperature, humidity, and mass flow from a tape deck according to aircraft ground and flight profiles programmed on magnetic tape. Random mechanical vibration control is semi-automatic. The design, engineering development, and partial performance capabilities are documented. (Author)
