EPS Diesel Making Steady Progress Toward Certification

NEW RICHMOND, WIS. – Since introducing the first modern aircraft diesel engine developed from a “clean sheet” design at EAA AirVenture Oshkosh in 2014, Engineered Propulsion Systems (EPS) has completed Phase One of their flight testing program, added staff, production facilities, sophisticated tooling and will soon be launching advanced tests with pre-production engines.

Expectations were met or exceeded with the first two concept engines. Dick Rutan will resume collecting performance data in the fair skies over Mojave, Calif., with a pre-production engine. A second pre-production engine will be tested and calibrated on EPS’ mobile static system developed for ground tests. They are also refining software that is designed to significantly lighten pilot workload.

As the airborne and ground tests continue, the company is slowly adding staff, new production facilities and high tech equipment. “The progress has been encouraging,” said EPS President, Michael Fuchs. “We have a lot of work in front of us, but the early results have confirmed that the ideas and reality are in sync. Our team is synthesizing a lot of new technology and we are optimistic about the future. The benefits that will accrue as General Aviation transitions to diesel will be substantial and global in reach.”
