Diamond Aircraft has selected the Williams International FJ33-4 engine as the power plant for the new D-JET. The engine, a scaled derivative of the FJ44 engine family, provides 1,400 lbs of thrust rated to 72 degrees Fahrenheit and incorporates a dual-channel FADEC.

Christian Dries, Diamond Aircraft ceo, said: “We selected the FJ33 because of its demonstrated outstanding performance, its advanced stage of development and because it will be both FAA and JAA certified in the timeframe needed to support our development programme.”

The D-JET is Diamond’s first entry-level personal jet, with a cruise speed of 315 knots and a maximum operating altitude of 25,000 feet.

Williams’ engineering team will work collaboratively with Diamond’s engineering team to design the air inlets and on integration of the engine into the D-JET. Williams will also be providing a ‘built-up’ engine, ready for direct installation into the production aircraft.
