Engineered Propulsion Systems’ (EPS) Vision 350 diesel engine, currently in development for general aviation airplanes, recently achieved a milestone in its initial test program. Engineers parked the EPS mobile testing lab at Hartzell Propeller’s headquarters in Piqua, Ohio, where the engine proved capable of spinning Hartzell’s traditional aluminum, ASC-II composite and Bantam composite graphite propellers without the need for engine vibration dampers.
According to EPS, the testing showed that the engine’s design features make it a smoother running engine than many traditional general aviation engines and any other diesel engine.
