Among turbofan manufacturers, Williams International remains tops with AIN readers for the support it provides to operators. Rolls-Royce, combined into one listing this year for the first time instead of being separated into R-R and R-R Deutschland, takes second place and, by barely a gnat’s whisker, bumps Pratt & Whitney Canada to third place.
With the deadline for the comment period on the Environmental Protection Agency’s advanced notice of proposed rulemaking (ANPRM) to phase out leaded avgas having just passed, many in the industry remain galvanized for possible effects of the proposed mandate.
Turbofan manufacturers are developing cleaner, quieter and more environmentally friendly engines that will meet current and future regulatory requirements. That fact should come as no surprise, since they have been doing this all along as the natural byproduct of efforts to build more fuel-efficient and quieter turbofans for a market that demands nothing less.
The FAA awarded contracts valued at $125 million to several manufacturers to develop and demonstrate technologies that will reduce jet aircraft fuel consumption, emissions and noise.
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.
Centurion Aircraft Engines’ Centurion 2.0s is now available in Europe as an upgrade through a supplemental type certificate (STC), which covers installing the 155-hp engine on the Cessna 172F through -S models. EASA issued the STC to Centurion on May 21. The 2.0s provides 20 more horsepower than the original Centurion 2.0. It is Fadec-controlled to keep engine parameters within range and is operated through a single lever power control.
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?
