NEW RICHMOND, WIS. – Engineered Propulsion Systems (EPS) mounted its first in a series of pre-production diesel engines on a test stand on September 20, 2015. Based on data collected from two earlier “concept engines,” EPS initiated a number of refinements in the design and assembly of its pre-production engines. After extensive tests on their Mobile Engine Test Laboratory in the U.S. and a Dynamometer facility in Germany, the engine will be shipped to Mojave, California and mounted on an EPS-owned Cirrus aircraft, where it is expected to satisfy certification criteria. Aeronautical engineer, Dick Rutan, will be conducting the flight tests.
