U.S. Army extends Chinook engine contract

  • 20-Nov-2009 04:54 EST

The T55-GA-714A engine delivers 4868 hp, enabling the CH-47F helicopter to reach speeds in excess of 175 mph and to transport up to 21,016 lb.

The U.S. Army finalized a $79 million contract to continue purchasing Honeywell T55-GA-714A engines and fielding kits for Chinook helicopters. More than 5300 T55 engines have been delivered since its launch, with more than 7 million h of global operation. Honeywell’s engines are being installed on both legacy CH-47D and new CH-47F helicopters. Deliveries to the Boeing CH-47F production line from this latest order will begin in the first quarter of 2010. The U.S. Army has options for two additional years. The 714A delivers a 17% increase in power, 5% reduction in fuel consumption, and increased maintenance intervals when compared to the previous 712-model engine.

After many years of flat-lining in the supply of new commercial jet engines—with improved models, but with designs dating back to the late 1990s, relying on a continuous path of evolutionary development—a new generation of super-efficient powerplants is entering service, introducing many technologies that will also be applied to future engines.
SAE International is working with the joint-venture initiative looking to deploy a high-powered DC fast-charging network for battery electric vehicles (BEVs) covering long-distance travel routes in Europe.
Fuel efficiency—and the economic and ecological benefits associated with it—continues to be the white rabbit of the global aviation industry. While engine builders look toward composites and electrification, and airframe designers toward lightweighting and aerodynamics, engineers at NASA’s Glenn Research Center recently completed testing of a novel concept: the boundary layer ingesting propulsor.
S.S. White Technologies is supplying flexible rotary shafts for the Honeywell Aerospace Air Turbine Starter on the next-gen GE Aviation GE9X high-bypass turbofan engines.
