Rotor Burst Protection Program: Statistics on Aircraft Gas Turbine Engine Rotor Failures that Occurred in U.S. Commercial Aviation During 1974.
Abstract
Presented in this report are statistics on gas turbine rotor failures that have occurred in U.S. commercial aviation during 1974. These statistics are based on data compiled from the Flight Standards Service Difficulty Reports (SDR) that were published by the Department of Transportation, Federal Aviation Administration (FAA). The compiled data were analyzed to establish: (1) the incidence of rotor failures and the number of contained and uncontained rotor bursts; (2) the distribution of rotor bursts with respect to engine rotor component--i.e., fan, compressor or turbine; (3) the type of rotor fragment (disk, rim or blade) typically generated at burst; (4) the cause of failure; (5) the type of engines involved; and (6) the flight condition at the time of failure. It appears that causes beyond the control or scope of present technology, such as F.O.D., structural life and integrity prediction, and secondary effects, are still primarily responsible for most of the rotor failures that occur.
