An Experimental Facility for Dynamic Combined Environments Reliability Testing of Airborne Equipment.

摘要

A newly developed experimental facility can assess in-service reliability of airborne equipment under the dynamic combined environments encountered in flight. Virtually complete simulation of the airborne equipment environment is achieved by predominantly magnetic tape controlled scheduling of random mechanical vibrations, compartment air temperature, altitude, cooling air flow rate, temperature, and humidity at the rapid rates of variation produced in high performance aircraft. The design, engineering development, operational capability, and associated aspects of construction and operation are documented along with some early operating experience with actual avionics hardware.
