Environmental Control Accessories Test Facilities Needed for Life and Reliability on Future Projects

Increasing demands for larger aircraft that can fly faster, farther, and higher with assurance of reaching their destinations and returning to their points of origin have far outstripped the availability of in-service experience upon which to base design reliability requirements. This paper describes test facilities that can provide this needed information by increasing component requirements beyond the known reliability criteria. The authors propose extended research and investigation into projected reliability parameters that will assume greater importance as flight ranges and altitudes are expanded for both military and civilian aircraft.
