Prediction of the vibration environments of future aircraft using data collected from past aircraft

Bolds collected aircraft vibration data using test flights to collect information about the vibration environments that exist around vehicles during normal flight conditions. To analyse the enormous amounts of data, processing techniques such as spectrum analyzers and minicomputers were used. Bolds's spectral analysis of aircraft vibration and noise was called "substantial" and "instrumental" in suggesting ways to correct the adverse effects of the severe aeroacoustic environment created by operating high performance aircraft with their weapons bay doors open. Her work on helicopter vibration frequencies helped to demonstrate that the Helicopter Vibration Test Curve "M" in use in 1970 was inadequate, as it could potentially create many instances of field equipment failure. She continued to publish regular reports from the vibration and aeroelastic facilities.
