Engines in 2014

Rolls-Royce ran the Trent 1000-TEN for future Boeing 787 variants in May, launched the Trent 7000 for the reengined Airbus A330neo in July and the same month ran the uprated Trent XWB-97 (pictured) for the stretched A350-1000 for first time.

An uncontained turbine failure of a Pratt & Whitney PW1500G geared turbofan at the end of May grounded Bombardier’s CSeries test fleet for 100 days. Flying resumed in September after the engine oil lubrication system was redesigned.

Reaction Engines in June revealed ambitious plans, backed by the U.K. government, to build and test a full-scale Block 1 ground demonstrator of its Sabre air-breathing rocket engine, to run by 2019.

Lockheed Martin F-35s were grounded in June and missed their international debut in the U.K. after a “hard rub” in the fan section of a Pratt & Whitney F135 engine caused a rotor failure. A “burn-in” process was developed to remove flying restrictions while a long-term fix is developed.

After 10 years of operations, Insitu announced it will replace the engine on its ScanEagle small long-endurance unmanned aircraft with a purposed-designed powerplant developed by Australia’s Orbital.

Pratt & Whitney’s PW1100G geared turbofan (GTF) powered the Airbus A320neo in its September first flight. In 2015, the GTF is due to enter airline service on the A320neo and Bombardier CSeries and begin flight-testing on the Mitsubishi Regional Jet (MRJ).

CFM International’s Leap-1 engine flew for the first time in October, when the Leap-1C for the Comac C919 took to the air on GE’s Boeing 747 flying testbed. The Leap-1A (pictured) for the Airbus A320neo followed in December. The Leap-1B for the Boeing 737 MAX ran for the first time in June.

Flown on a Boeing 747 testbed in October, Rolls-Royce’s new composite-titanium fan blade is a key element of its next-generation Advance large turbofan and UltraFan ultra-high-bypass geared turbofan designs for the 2020s, unveiled in March.

GE Aviation completed ground tests of an adaptive-fan combat engine demonstrator, with variable bypass ratio to maximize fuel efficiency while providing high thrust, achieving record combined compressor and turbine temperatures.

Under Europe’s Clean Sky research program, Airbus Helicopters began ground tests of a diesel-cycle engine in an EC120 light helicopter, aiming for 30% lower fuel consumption and fewer emissions than a turbine engine.

U.S.-based Honda Aero delivered its first production HF120—developed jointly with General Electric—to Honda Aircraft in November, for the HondaJet, and has teamed with Sierra Industries to reengine Cessna CitationJets.

In December, Congress gave the Pentagon $220 million to accelerate development of a U.S. rocket engine and end by 2019 its reliance on the Russian RD-180 to power United Launch Alliance’s workhorse Atlas V booster.
