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.

Boeing moved quickly this month to erase any doubts about the progress of the 787 flight-test program after “an assessment of the availability of an engine needed for the final phases of flight test this fall” led it to conclude that it couldn’t deliver the first production airplane until the middle of next year’s first quarter. Last week, all five flight-test airplanes remained active, said Boeing.

Boeing CFO James Bell told analysts last month that the new turbofan designs ...

Pratt & Whitney and CFM might not like to hear it, but if the assertions of Boeing CFO James Bell prove accurate, the 15- to 16-percent fuel efficiency gains the engine makers have repeatedly advertised for their respective next-generation turbofans will translate into less than double digits if and when they make their way onto existing narrowbodies.

International Aero Engines (IAE) has identified a problem area with some of its V2500 engines and is inspecting engines in the fleet as a result. The issue involved the engine's high-pressure compressor (HPC), specifically the third through eighth stages of the 10-stage HPC requiring certain fasteners' replacement. This issue has resulted in the grounding of nine of Kingfisher Airlines' 34 Airbus A320s.

The U.S. FAA and Europe’s EASA jointly certified CFM International’s new CFM56-7BE engine for the Boeing 737 family last Friday.

CFM expects the engine to begin Boeing 737 flight testing during the fourth quarter and enter service in mid-2011, in time to coincide with Boeing Next-Generation 737 airframe improvements.
