Engine/Airframe/Drive Train Dynamic Interface Documentation.

Abstract

An historical review of Kaman Aerospace Corporation helicopter development effort was conducted. Information pertaining to instances of engine/airframe/drive train incompatibility was extracted from the resulting review data. The details of each incompatibility problem and its solution are presented and discussed. These problems were found to be associated with normally occurring rotor and drive system vibratory excitations and resonance amplified rotor and drive system vibratory excitations. It is concluded that the type of incompatibility problems encountered in helicopter development programs can be expected in the future. For the most part, these problems, and their solutions, are an intrinsic part of the development process, and they will not be eliminated through the application of increasingly more sophisticated and complex analytical design tools. It is recommended that research in this area by directed towards improved dynamic testing methods which will enable more rapid, efficient determination of the exact nature of future incompatibility problems, once they are encountered.
