New U.S. Rocket Engine Boosted
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.

CSeries Grounded
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 Aims High
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.

F135 Hitch Keeps F-35 Away
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.

ScanEagle Matures
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.

GTF Powers A320neo Aloft
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).

Leap-1's Progress to Flight
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.
