The Powerjet SaM146 received its EASA certification yesterday, June 23, some six years after Snecma of France and Russia's NPO Saturn founded the joint venture to build the engine and more than seven years after Sukhoi Civil Aircraft chose the engine to power the Superjet 100.

Composites and other new and expensive materials play key roles in the engines that will power new single-aisle airliners, such as the Comac C919, Bombardier C Series and, possibly, Airbus A320 and Boeing 737 upgrades. Pratt & Whitney and CFM aim to make their future engines more efficient with material changes-some low profile, others better known-that all contribute to double-digit improvements in fuel consumption.
Boeing's decision to re-engine the existing 737 will depend not only on the actions of arch-rival Airbus, but whether or not the Chicago-based airframe maker concludes that it could bring to market a good enough replacement airplane by 2020, Boeing CEO Jim McNerney told analysts and investors at last week’s Sanford C. Bernstein Strategic Decisions Conference in New York.
It seems Boeing hasn’t convinced everyone of the value of its standard engine interface feature on the 787 Dreamliner, which the company says allows quick and cost-effective changeability between the Rolls-Royce Trent 1000s and GE GEnx-1B turbofans chosen to power the airplane.
Rolls-Royce today announced that it has successfully run the latest E3E (efficiency, environment, economy) core engine as part of its two-shaft research program, which is intended to develop future powerplants for business jets and single-aisle airliners. The latest core build produced “excellent results” during 40 hours of run trials at Stuttgart University’s altitude test facility, exceeding flight-envelope requirements, the company said.
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.
Sukhoi Civil Aircraft (SCAC) managed to fly the fourth Superjet 100 prototype for the first time on February 4, notwithstanding continuing delays associated with the airplane’s engines, built by the joint venture between France’s Snecma and Russia’s NPO Saturn known as Powerjet.
The fourth Boeing Dreamlifter–the final airplane in the fleet of 747-400s specially modified to carry large sections of composite parts for the 787–entered service today, the manufacturer announced this afternoon. Dreamlifters transport the structures from partners around the world to Everett, Wash., for final assembly.
In an deal valued at $500 million, Turkish Airlines has ordered V2500 SelectOne turbofans to power its A320-family aircraft for which is has placed 20 firm orders and taken options on 10 more. Engine maker International Aero Engines (IAE) is to make deliveries in the 2011-2013 time frame. The firm order covers powerplants for a mix of six A319s and 14 A321s. IAE is a joint venture between Rolls-Royce and Pratt & Whitney.
