The United States Military has increased their demand for engines that can fly in Unmanned Aerial Vehicles (UAVs). These engines must be powerful and light enough to maximize the aircraft’s efficiency. The objective of this project is to model the O’Neill Motor Company, Inc.’s innovative coaxial counter-rotating cam engine called the NorEaster. We performed dynamometer tests and pressure tests on the existing NorEaster engine prototype and developed models for both gasoline and diesel NorEaster engine designs. Using our mathematical models, we identified the optimal power to weight ratio of a diesel engine design to be 0.49. Based on these results, we recommend further development of an eight cylinder diesel engine at the specified parameters.
