Description

An opposed piston, opposed stroke is a unique diesel engine design as each cylinder contains two pistons which means that the combustion chamber is captured between the two pistons as they move towards each other. In this thesis project, an opposed piston, opposed stroke diesel engine was designed for use in utility aircraft. Utility aircraft are used for commercial purposes with a maximum takeoff weight of 12,500 lbs and commonly powered by gas turbine engines that drives a propeller. Compared to the turboprop alternative, opposed piston diesel engines offer a greater power density, weight reduction, and increases in fuel, thermal, and combustion efficiencies. In conjunction with the Foundation for Applied Aviation Technology, specifications for the engine have been prepared, including a required 800 hp at takeoff. As part of the research project, an analytical simulation model was formulated to determine the appropriate physical dimensions and a virtual prototype was produced.
