Abstract:
The objective of the Helicopter Transmission VibrationNoise Reduction Program was to generate analytical tools for the prediction and reduction of helicopter transmission vibrationnoise that provide the capability to perform trade studies during the design stage of a program. Application of this optimization capability yields drive train components that are dynamically quiet with reduced vibrationnoise levels and inherently longer life.
