INSTRUMENTATION FOR PROPELLER BLADE VIBRATION FLIGHT AND GROUND TESTING
The need for in-flight propeller stress measurements has been evident for the last three decades. This report documents the various instrumentation systems, methods, and techniques particularly suited to this purpose. The stress measurement process, in general terms, is considered with a more detailed description of the various options available to transmit signals from the propeller to the airframe. The procedures with which the transmitted signals may be recorded, processed, and reduced to meaningful information are presented with an assessment of their relative merits. An in-depth description of strain gage installation techniques is presented, depicting short- as well as long-term all-weather installations, heretofore uncommon in the state-of-the-art. Further discussion is addressed to electronic data processing and a typical flight test profile.
