REFLECTOR: First Flight For EPS Diesel Engine

Sun May 18 12:01:20 CDT 2014

I'll resend this... Maybe you guys didn't get it....

450 HP.......... 
They need 875 ft.lbs. of torque at 2700 rpm's to get that horse 
power.... It is a 4.4 liter (268 ci.) displacement engine...

•  Configuration:     “Flat-Vee” 8-cyl. 4-stroke Diesel•  Displacement:     4.42 liters•  Max. Power:        ≥ 350 bhp @ 3800 rpm•  Fuel Cons:           ≈ 12.3 gph @ 250 hp setting•  Fuel:                    Jet A, Jp-8, or diesel•  Cooling:              Integrated liquid-cooling•  Engine Control:  Electronic engine management•  Target Weight:   ≤ 298 kg, (wet running weight) (657 lbs)

I do not have the numbers handy, but the installed weight of the EPS was actually expected to be few pounds lighter then the Lycoming IO-540-U2A in my Aerostar. Both setup as 350HP engines.

    I'm surprised nobody has commented on
      the installed weight.

      The horsepower is 350hp on 10gph.

                  Things are looking bright
                        in the alternative engine scene. 

                  Do watch the video I linked
                        at the bottom of the article. - Richard

                    First Flight
                        For EPS Diesel Engine
                    By Mary Grady ,
                      Contributing editor | May 14, 2014

                    Calling it a "new paradigm in aviation
                      propulsion," test pilot Dick Rutan completed the
                      first flight of the quiet new Graflight V-8 diesel
                      engine from the Mojave airport, on May 2. The
                      engine was installed in a modified Cirrus SR22.
                      The test flight took about 20 minutes, staying at
                      altitudes 5,000 feet and less. The team plans to
                      test-fly the engine for 40 hours over the next
                      three months, then fly it to EAA AirVenture at
                      Oshkosh for a public debut in July. The engine is
                      controlled by a single power lever, and is
                      designed with rugged technologies that will expand
                      time between overhauls to 3,000 hours, the company
                      says. It can be fueled with Jet-A, JP-8, or
                      straight diesel.

                    Throughout the testing phase, EPS said it will
                      monitor 80 different channels of data on the
                      engine, focusing mainly on pressures and
                      temperatures of oils and coolants, and closely
                      monitoring intake and cooling air. The engineers
                      also will check drivetrain vibrations, horsepower,
                      and fuel economy in flight. At the end of the test
                      phase, EPS hopes to have proven definitively that
                      the fuel savings recorded in over 500 hours of
                      ground testing is equaled or greater in actual
                      flight. Work on the pilot-engine interface will be
                      managed by Dick Rutan. The project was launched by a
                      Wisconsin firm in 2010. The company says it
                      expects the engine to be certified in 2016.
