CH-46 ROTOR ACOUSTICS ANALYSIS: CONTINUED ANALYSIS OF INFLIGHT MANEUVERS

摘要

This paper summarizes the continued CH-46 in-flight data analysis for the rotor acoustic monitoring system (RAMS). This ambitious 38-month proof-of-concept effort, which was a part of the Naval Surface Warfare Center Air Vehicle Diagnostics System program, culminated in a successful three-week flight test of the RAMS system at Patuxent River Flight Test Center in September 1997. This paper presents the results of additional signal data analysis of the flight-test dataset over analysis results previously reported in 1998 and 1999.
