Fuel Leak Detection System for Aircraft (Air Force)
Abstract
This FCT will evaluate two systems, Extrima manufactured in Sweden by Adixen and a Helium Hydrogen System manufactured in France by Aerowing. These systems have the potential to greatly improve leak detection during depot maintenance, thus reducing unexpected labor costs and improving aircraft quality and delivery to the war fighter. The primary outputs and efficiencies to be demonstrated in the FCT is the qualification of a safe (NEC Class I Div1) tracer gas leak detection system for F-16, A-10, and C-130 full aircraft and off air frame components. Current specified pressure bleed down and bubble leak check methods used to detect fuel leaks in full aircraft and off airframe components are slow, inaccurate, and result in leaks not being detected until an aircraft is refueled prior to the initial check flight. Leaks detected at this time add unexpected labor (Over 4000 Hrs for the F-16 April 2008 to 2009) from additional fuel system defueling and purging, aircraft towing, airframe component removal and disassembly, along with potential increases (as an example for the F-16) of 30 to 45 day aircraft flow days. Current methods do not allow leak detection in complex assemblies without disassembly such as in and around wing leading edge wiring, rotary actuators, pylon attach points, and wing attach fittings. If successful this, the system(s) can potentially be used at depot, field level, and Deparment of Defense wide for multiple weapon systems.
