Rolls-Royce’s strategy of feeding technological developments from new programs back to established engines for upgrades or retrofit changes is creating a range of enhanced-performance (EP) packages being available to customers.

GE’s 2,000-shp CT7-2E1, the powerplant for the twin-engine AgustaWestland AW189, received FAA certification last week. The CT7-2E1 is the latest civil-certified addition to the CT7/T700 line, with Fadec and what GE describes as a state-of-the-art hot section for power and reliability. The first production-certified CT7-2E1s will be delivered to AgustaWestland this month, GE said.
BBA Aviation unit H+S Aviation recently announced an expansion of its CT7 series engine care management program (ECMP) and engine overhaul subcontract agreement (EOSA) with GE Aviation. Based in Portsmouth, UK, H+S Aviation provides engine service and support for a variety of turbine engines for fixed- and rotary-wing civil and military aircraft.
GE Aviation has expanded its CT7 engine overhaul subcontract agreement (EOSA) with H+S Aviation to include all CT7-5A and CT7-9B engine care maintenance program (ECMP) commercial engine shop visits. Under the terms of the agreement, GE will continue to manage CT7 ECMP contracts and supply OEM parts to H+S, which will perform all labor on engine shop visits.
In 2011, CT7-5A and -9B engines accounted for 170 shop visits, more than 80 percent of all CT7 shop visits.
Thailand has signed a letter of offer and acceptance covering two Sikorsky UH-60M Black Hawk tactical transport helicopters. They are being acquired through U.S. Foreign Military Sales channels and, after delivery to the Royal Thai Army, will be the first examples of this new generation of Black Hawk operating in Southeast Asia.
Dark clouds and a strong breeze failed to prevent yesterday’s unveiling of AgustaWestland’s latest civil helicopter, the eight-ton multi-role AW189. “This reminds me of the North Sea, one of the working environments our new helicopter was designed for,” said AgustaWestland CEO Bruno Spagnolini.
The U.S. Defense Security Cooperation Agency (DSCA) notified a potential sale to Sweden of 15 Sikorsky UH-60M Black Hawk helicopters. Estimated at a value of $546 million, the request also covers 34 General Electric T700-GE-701D turboshaft engines and 15 defensive aid sets, each comprising AAR-57(V)3 missile warning, APR-39 radar warning and AVR-2B laser warning systems.
A new General Electric turboprop engine, derived from the 7,500-shp GE38-1B turboshaft engine, could become available by the middle of the decade. GE has designated the new engine study CPX38, and is basing it on the turboshaft that will power the U.S. Marine Corps’ new heavy-lift helicopter, the Sikorsky CH-53K. This could mean that the CPX38 would be in the 5,000- to 6,000-shp range.
Helicopter manufacturer AgustaWestland is here at the Farnborough airshow with three new aircraft: the civil GrandNew and the military AW159 Lynx Wildcat and AW149. All made their first flights during the last 12 months, although flight testing for the development of the Grand derivative is believed to have started two years ago.
