Abstract : The report on Project EASY describes the results of the development and 12-month service test of an engine analyzer system combining airborne and ground equipment to automatically collect and process engine performance and stress data to verify that an engine will accomplish the next mission with high confidence, diagnose a faulty engine, and predict maintenance requirements. A detailed description of the EASY equipment, its aircraft installation, and maintenance experience is included. EASY test experience and results with tables, figures, data plots and narrations relating to computer programs, data printouts, analysis, and diagnostic procedures of typical engine malfunctions are presented. Economic justification based upon the results of an extensive Cost Effectiveness Analysis in accordance with DOD Instructions 7041.3, 'Economic Analysis of Proposed Department of Defense Investments,' dated 19 December 1966, is also included. Fleet implementation considerations, pertaining to EASY equipment improvements, installation recommendations, personnel training, and data processing and documentation, are discussed. Although the EASY equipment used in service test was configured for the F-4C/J79-GE-15 and F-105F/J75-P-19W aircraft-engine combinations, modification to accommodate other engine types and subsystems as well as other parameters not presently included can readily be made. The system equipment is general purpose but the installation and data programming must be tailored to each aircraft engine and subsystems combination. (Author)
