The fray fault of the aircraft wire is always considered difficult to be detected. But it would be a serious threat to the safety of the aircraft. As the flight of the aircraft, the fray fault can be more and more serious and it would become open or short circuit at last. In this paper a new and useful method was proposed to deal with the fray fault. A mathematic model of aircraft wire fray fault...
Advanced diagnostic and prognostic technology promises to reduce support costs and further improve safety of flight. The ability to detect fault precursors and predict remaining useful life can provide longer periods of uninterrupted operations as well as reduce support costs and improve crew response to degrading conditions. Two major barriers to realizing this potential include the cost of implementation...
Electrical wiring and interconnected systems (EWIS) have become a major area of research and development for variety of industries. A variety of factors lead to catastrophic failure described. Here partial discharge (PD) analysis methods for diagnosing aircraft wiring faults are explored since PD signals are strongly correlated with the defects that produce them and form an ideal part for prognostic...
Wiring onboard of legacy aircraft is becoming a liability due to a prolonged use of aircraft. Testing as well as repairs and maintenance require extensive number of man-hours bringing up the costs and reducing flight time of the aircraft. There is a number of conventional electric testing methods for wire testing, yet we propose and evaluate an acoustic (mechanical) testing method. Acoustic testing...
