Rolls-Royce on Wednesday revealed plans for a new generation of engine designs to replace the current Trent family. The first, called Advance, would reach the market by the end of this decade, burning at least 20 percent less fuel and emitting 20 percent less CO2 than the first generation of Trent engine. The second, dubbed UltraFan, would enter service by 2025 and use a geared design and a variable-pitch fan system capable of delivering at least a 25-percent improvement in fuel burn and emissions.
EADS has set itself an ambitious target for its E-Thrust hybrid propulsion concept, a joint effort with British engine maker Rolls-Royce that went relatively unnoticed when it was revealed at the Paris Air Show in June. The E-Airbus, under its new moniker, is to enter into service in 2030 as a 100-seat regional aircraft.
French engine manufacturer Snecma has been selected as the sole powerplant supplier for the new Dassault Falcon 5X, which was unveiled earlier this week here in Las Vegas. The new Silvercrest turbofan, rated at 11,450 pounds of thrust at takeoff and with a thrust-to-weight ratio of five, is expected to be certified in 2015. It will be the culmination of a 10-year effort, as Snecma began considering designing its first business jet engine in 2005.
Orders from Singapore Airlines covering up to 50 additional Rolls-Royce (R-R) Trent XWB-engined A350-900s boosted Airbus as it made final preparations late last month [May] for the new airliner’s first flight. The Asian carrier has booked 30 examples and taken options on 20 more (convertible to larger A350-1000s), boosting the total number of A350-900s it has ordered to 70.
Snecma has started running the first Silvercrest turbofan at its Villaroche test facility near Paris, France. With 11,000 pounds of thrust, two of the units will power the Cessna Longitude super-midsize business jet.

EASA engine certification is slated for 2015 and FAA validation is expected shortly thereafter.
An all-new RB3025 engine concept has been created by Rolls-Royce following a Boeing request also extended to General Electric and Pratt & Whitney for a powerplant for a future 777-size aircraft in around 2020. The current 777 is powered exclusively by the GE90.
Rolls-Royce has selected a 132.5-inch diameter for the composite fan for the 99,500-pound-thrust engine, which will sport a 12:1 bypass ratio and a 62:1 overall pressure ratio that would be the highest achieved on a commercial aircraft.
S.S. White Technologies (Hall 4 Stand A4) has been selected to provide flexible rotary shafts for the Pratt & Whitney PW1000G engine’s nacelle. The shafts will transfer power on the variable area fan nozzle (VAFN) and synchronize actuators on the thrust reversers. The U.S. company has already provided two flexible rotary shafts for the thrust reverser rig, and previously supplied two flexible shafts for the VAFN test setup.
CFM International remains on track with development process of the Leap series of engines that it laid out four years ago. The 50/50 partnership between General Electric and Safran subsidiary Snecma announced it has recently frozen the designs for its new Leap 1A and 1C engines destined for use on the Airbus A320neo and the Chinese Comac C919 narrowbody airliners, which are scheduled to enter service in 2016.
The Kuznetsov design bureau, part of the United Engine Corporation (ODK), unveiled a new geared turbofan design at the Engines 2000 exhibition in Moscow last month. The PD30 is proposed for an upgrade to the Antonov An-124 Ruslan heavy airlifter, which is currently powered by the Ukrainian Ivchenko Progress D18T. The PD30 could also power Russia’s proposed widebody airliner, known as Airplane 2020.
