Abstract

The failure rate of helicopters is 2.5 times that of fixed- winged aircraft and the lead time from fault development to complete failure is as short as 15 minutes. Thus, it is very crucial to warn pilots as much in advanced as possible. Here Canonical Discriminant Analysis technique was ap[plied to classify the various failure modes in helicopter gearbox. Experimental data was used to assess the performance of the proposed algorithms. Simulation results showed that the algorithms performed extremely well.
