METHODOLOGY FOR TURBINE ENGINE LUBRICATION SENSITIVITY ANALYSIS

UNDER THIS PROGRAM THE CURRENT AND PLANNED LUBRICATION SYSTEM DESIGN APPROACHES FOR ADVANCED GAS TURBINE ENGINES SUCH AS THOSE BEING DEVELOPED UNDER THE INTEGRATED HIGH PERFORMANCE TURBINE ENGINE TECHNOLOGY (IHPTET) INITIATIVE WILL BE REVIEWED, THE AVAILABLE LUBRICATION SYSTEM PERFORMANCE DATA WILL BE ASSEMBLED, AND THE PROJECTED MISSION PROFILES SUCH AS INTERCEPT, COMBAT PATROL, CLOSE AIR SUPPORT OR TACTICAL TRANSPORT AND THE ASSOCIATED MAJOR ENGINE CLASSES EXPECTED FOR THESE MISSIONS WILL BE IDENTIFIED. ADDITIONALLY, THE CAPABILITY OF AVAILABLE ENGINE CYCLE DECKS TO INCORPORATE LUBRICATION SYSTEM PERFORMANCE DATA AND TO BE IMPLEMENTED ON A PERSONAL COMPUTER WILL BE ASSESSED. USING THE GATHERED DATA, AN ENGINE CYCLE DECK WILL BE SELECTED AND THE FUNDAMENTAL LUBRICATION SYSTEM MODELS AND ALGORITHMS FOR LIQUID, POWDER AND EVEN UNLUBRICATED SYSTEMS WILL BE IDENTIFIED. FINALLY, A PLAN WILL BE PREPARED FOR THE DEVELOPMENT AND IMPLEMENTATION OF A GAS TURBINE ENGINE LUBRICATION SYSTEM PERFORMANCE ASSESSMENT SOFTWARE RESOURCE THAT CAN OPERATE ON A PERSONAL COMPUTER.
