Wichita State University (WSU) supports the Federal Aviation Administration (FAA) research in the area of Operational Loads Measurement of commuter and general aviation aircraft. This research is aimed primarily at acquiring and reducing typical in-service usage data for the purpose of better understanding the flight loads experienced by the airframe. The program includes developing improved methods and criteria for processing and presenting large amounts of data. These activities result in information that can (1) lead to the understanding of the service-related factors affecting the operational life of the aircraft and (2) allow the FAA to reassess continued suitability of existing certification criteria. The University of Dayton Research Institute (UDRI) published the results from the processing and analysis of digital flight recorder data obtained from 910 flights of 30 BE-1900D aircraft during typical operational usage by a single commuter airline. These aircraft employ propellers with composite structures. The data used by UDRI also contained some information on engine and propeller usage, such as engine revolutions per minute (rpm) and torque and time at propeller reversal. This report documents the efforts of WSU to derive statistical summaries of aircraft usage data, ground operations data, and flight operations data pertaining to the propellers from this database. Statistical data are presented for parameters such as torque correlated with rpm, time in propeller reversal, alpha, and unsteadiness in alpha due to gust velocities. The scope of activities performed encompasses the service-related factors that affect the operational life of the propeller, as defined by the propeller manufacturer. WSU has generated the processed data in statistical formats that can enable the FAA, the propeller manufacturer, and the airline to better understand and control those factors that influence the structural integrity of these components.
