Diamond D-JET to get higher-thrust Williams FJ33 engine March 13th, 2008
Diamond Aircraft has selected a newer, higher nominal thrust engine in the same Williams engine family for the D-JET – the FJ33-5.
The engine's advantages include several technological advances that result in better bleed air handling and improved specific fuel consumption. With a 1,900-lb nominal thrust versus 1,564 lbs for the originally planned FJ33-4, the ‘FJ33-5' also offers a potential future performance upgrade path for the D-JET. Williams International's accelerated development schedule of the FJ33-5 has made it viable to proactively launch D-JET deliveries with this engine rather than reactively introducing it at a later date in response to competitive pressures.
"The FJ33-5 engine is the perfect match for the D-JET, offering the latest technology and a potential performance and utility upgrade path for delivered aircraft that the current engine just doesn't allow. While making this change now rather than later means that initial deliveries will now be in Q2, 2009, we are confident this is the right choice and in the interest of all D-JET customers, as it ensures one configuration and maximum resale value for all delivered aircraft," said Peter Maurer, President of Diamond Aircraft.
Diamond will deliver the FJ33-5-equipped aircraft to current position holders at the contracted price; however, the company announced that a price increase for future orders is expected shortly.
"The FJ33-5 is the very latest in turbofan engine technology and offers unique features never before available on a smaller turbofan engine," explained Matt Huff, Vice President of Business Development at Williams International. "We are pleased that our accelerated development schedule for this engine now makes it feasible for Diamond to launch with the FJ33-5, instead of introducing it after initial aircraft deliveries. Every D-JET customer will now benefit from technological advances, such as the built-in pre-cooler and new compressor technology."
