ADEPT-powered Velocity Begins Phase 1 Testing

The team at ADEPT Propulsion Technologies USA is thrilled to support the Phase 1 test program for the first ADEPT engine installed in an aircraft in North America.

The Velocity SE-RG is equipped with the ADEPT 280N, a naturally aspirated 280-hp, 120-degree V6 liquid cooled engine (designed to run on auto gas). During this phase of testing, we are thoroughly monitoring the integration of various systems, including electrical systems, avionics, engine mounting, and cooling systems. All engine data is being logged and continuously monitored by our factory representatives.

One of the key challenges of ground testing for pusher-type aircraft is the efficient management of cooling systems. We are confident that ADEPT’s advanced, liquid-cooled technology—combined with ECU-controlled coolant pump and thermally regulated fans—will provide an optimal solution, ensuring much lower ground operating temperatures compared to traditional air-cooled engines.

Preliminary results from testing have been highly encouraging. The engine operates with exceptional smoothness and is notably quiet. Its efficiency is impressive, and it demonstrates excellent hot-start characteristics. We look forward to documenting the Velocity SE’s performance as we work through the Phase 1 Flight envelope.
