Pratt & Whitney believes open rotors are not the solution to powering future single-aisle aircraft and will offer developed versions of its PW1000G series of geared turbofans for all new and derivative single-aisle aircraft.
Mitsubishi Regional Jet
Raytheon Gets the Nod for P-8I Radar
The time for refinements to the Mitsubishi MRJ has nearly passed, as Mitsubishi Aircraft expects to freeze the regional jet’s design within the next two months. The company has frozen all the interfaces between the various systems and the structural components, both in the 88-seat MRJ90, scheduled for Japanese certification in late 2013, and the 76-seat MRJ70, which would likely gain its certification roughly a year later.
More than 100 hours of testing on a full-scale PW1000G PurePower engine core has so far validated Pratt & Whitney's performance goals for its new generation of commercial jet engines, the company announced today. The core has also demonstrated “excellent” starting and operability characteristics, according to Pratt & Whitney.
Despite last year’s cancellation of the Cessna Columbus program, which would have been the launch customer for Pratt & Whitney Canada’s PurePower PW800 series of engines, progress continues on the 10,000-pound-thrust class turbofan, and the engine maker (Booth No. 328) is actively discussing applications with airframers for the new powerplant.
Germany’s MTU Aero Engines has finished building the first high-speed, low-pressure turbine for Pratt & Whitney’s PurePower PW1524G, the engine destined for the Bombardier C Series aircraft.
Mitsubishi Aircraft has hired the engineering division of BAE Systems Regional Aircraft to provide design integration and certification services for the development of its new MRJ regional jet. The program will focus on the integration of the aircraft’s propulsion system, specifically on the Pratt & Whitney PW1000G engine and its pylons, nacelles, auxiliary power units and fuel systems.
SIA Engineering (SIAEC) has signed an agreement to participate in Pratt & Whitney’s PurePower PW1000G engine risk-revenue sharing program (RRSP) with a 3-percent stake in the Bombardier C Series engine program and a 1-percent stake in the Mitsubishi Regional Jet engine program.
Pratt & Whitney Canada is evaluating options for expanding its customer support network in the Asia-Pacific region in response to a rapidly growing operator base for its engines.
Engineers and designers in Nagoya, Japan, have kept busy over the past year redrawing parts of the nascent Mitsubishi MRJ regional jet to satisfy the evolving desires of potential and existing airline customers. However, in the expectation that they will freeze the airplane’s design in the third quarter of 2010, the development team knows that the time for major changes has passed.
