Performance of a DC-9 Aircraft Liquid Nitrogen Fuel Tank Inerting System

Abstract

Nitrogen inerting protection for the fuel systems in commercial aircraft has been proposed to reduce fire and explosion hazards associated with refueling, electrical and mechanical failures, engine failures, in-flight fires, lightning strikes, and survivable crashes. A liquid nitrogen fuel tank inerting system was developed and installed on an FAA DC-9-15 aircraft. Instrumentation equipment and measurement techniques for evaluating the installed fuel tank inerting system performance were developed. A flight test program was conducted to demonstrate compliance of the DC-9 inerting system with applicable airworthiness standards, to evaluate oxygen concentration measurement techniques, and to verify that the installed inerting system maintained an explosion safe mixture in the fuel tanks over the entire flight envelope.
