NOVEL AIR GAP INSULATED PISTON

ADIABATICS, INC. IS PLEASED TO PROPOSE A RESEARCH PROGRAM TO DESIGN AN OPTIMUM PISTON FOR A HIGH TEMPERATURE MILITARY ENGINE. ADIABATICS, INC. HAS BEEN CONDUCTING A PROGRAM FOR TACOM TITLED "DEVELOPMENT OF TRIBOLOGICAL SYSTEMS AND ADVANCED HIGH TEMPERATURE IN-CYLINDER COMPONENTS FOR ADVANCED HIGH TEMPERATURE DIESEL ENGINES" FOR THE PAST FIVE YEARS. BASED ON OUR EXPERIENCE WITH DESIGNING COMPONENTS AND TESTING THEM ON A SINGLE CYLINDER AIPS ENGINE IT IS APPARENT THAT THE PISTON AND LUBRICATION SYSTEM ARE THE KEY COMPONENTS FOR THE SUCCESS OF THE ENGINE, AND MOST OF THE PROGRAM EFFORT HAS BEEN ON THESE ITEMS. A NOVEL PISTON DESIGN CONCEPT IS PROPOSED WHICH HAS THE POTENTIAL TO SOLVE SOME KEY PROBLEM AREAS WHICH HAVE BEEN IDENTIFIED DURING THE PROGRAM. THE PROPOSED PROGRAM WILL CONSIST OF EXTENSIVE FINITE ELEMENT ANALYSIS OF THE NEW NOVEL PISTON DESIGN INCLUDING MATERIALS SELECTION. THE NEW PISTON IS DESIGNED TO MEET THE PISTON HEAT REJECTION GOALS WITHOUT REQUIRING A THERMAL BARRIER COATING OR OTHER TYPES OF CERAMIC COMPONENTS.
