The June 16 first flight of the fifth Boeing 787 Dreamliner (ZA005) also marked the first time a pair of GE Aircraft Engines' GEnx-1B turbofans powered an airplane to altitude on their own. Captains Mike Bryan and Mike Carriker flew the airplane for three hours and 48 minutes, and reported no anomalies.
Engine manufacturers are here at EBACE providing a glimpse at where powerplant technology is going for business aviation with several clean-sheet designs or derivatives under development. Honeywell and Rolls-Royce each are working on two programs for business jets, while Pratt & Whitney Canada is involved in one. New players in the field–GE Honda and Snecma–each have a brand-new turbofan to promote, but the latter has yet to find
MTU Aero Engines held a “last bolt” ceremony to mark a major milestone in the development of Pratt & Whitney’s PurePower PW1524G geared turbofan engine slated to be used on Bombardier C Series. The company developed the engine’s turbine, which will now be sent to Pratt & Whitney to be installed on the first PurePower PW1524G engine. The engine will then begin testing procedures.
We hear a lot about turbofan engine research, in such things as unducted fans, open-rotor designs and geared turbofans. Where is rotorcraft engine technology headed?
GE Honda Aero Engines is putting the HF120 turbofan through its paces during the engine’s year-long certification tests, Bill Dwyer, president of GE Honda Aero Engines, told AIN during a recent visit to the company’s Cincinnati facility. Type certification is expected in the first quarter of next year.
While focused on delivering geared turbofan (GTF) engines for the new Mitsubishi MRJ and Bombardier C Series, Pratt & Whitney is turning its attention to the wider applications of a technology that offers a 12- to 15-percent improvement in fuel burn by allowing the engine fan and low-pressure turbine to operate at optimum speeds.
The GE Honda joint venture last Thursday fired up the first conforming version of its new 2,095-lb-thrust HF120 engine currently slated for certification in 2011. Initial engine tests are typically completed in a sea-level test cell, with high-altitude performance testing conducted onboard an aircraft.
The first GE Honda HF120 engine has successfully started its initial test run at GE Aviation’s altitude test chamber in Evendale, Ohio, the company announced yesterday at the NBAA Convention. “This is a significant milestone and represents the transition from the design-definition phase to the test and certification phase of the HF120,” said GE Honda Aero Engines president Bill Dwyer.
Going against the common practice of replacing rather than repairing, MTU Aero Engines has teamed with General Electric to make repairs more cost effective for the operator. “It is common for maintenance facilities to use new parts to replace worn or damaged ones, but we prefer to repair. Our technicians can restore even heavily worn components to as-good-as-new condition,” said Dr.
Chromalloy (Hall 3 Stand A33) has announced that the U.S. Air Force has selected it to provide module repairs during maintenance on the F108 gas turbine engine that powers the KC135R tanker aircraft. The follow-on award, valued at $15.8 million plus options, brings the total value of the contract to approximately $38 million over three years.
