F-111E Flight Vibration and Acoustics Test Program. Part 1. Test Instrumentation, Test Procedure and Data Reduction

Abstract : A comprehensive test program was conducted on an F-111E aircraft for the purpose of collecting dynamics data, primarily vibration and acoustic data, at selected locations throughout the aircraft under test conditions within the operational envelope of the aircraft. Data were recorded from 133 accelerometers and microphones at 60 test conditions including gunfiring passes. In addition, flight and engine parameter data were also recorded. The test program is documented by presenting the details on the test instrumentation, transducer locations, test procedures and flight conditions. Test results are limited to overall and peak root mean square (RMS) levels which give a coarse indication of the dynamics environment of the F-111E. Detailed test results will be presented in the parts of this report which will follow.
