Abstract

From August 28 to September 18, 1997, Honeywell's Rotor Acoustic Monitoring System was successfully flight-tested at Patuxent River Naval Base. This flight-test was the culmination of an ambitious, 40-month, proof-of-concept effort to demonstrate the feasibility of detecting crack propagation in helicopter rotor components. During the three weeks of flight-testing, the system was operated on 12 flights plus one ground test and accumulated more than 16 hours of flight data recorder data and about 25 Gbyte of digital data from eight on-rotor acoustic sensors. The flight-test showed that rotor head acoustic monitoring could be uniquely valuable not only for rotor crack and fault detection but also for monitoring the general health of the entire rotor assembly. This paper presents preliminary results from that flight-test.
