Starting with its first “clean sheet” engine design since 1972, but minus one of the two original customers, Honeywell brought the new AS907 to dual FAA engine and production certification in June, just 44 months after the project was launched.

On June 10 Honda flew its latest jet engine design for the first time. In the 1,900-lb-thrust range, the engine flew on a modified Cessna CitationJet from Honda’s purpose-built research facility at Atlantic Aero in Greensboro, N.C. Concurrently, Honda is busily at work on a CJ-size airframe in Greensboro, with first flight expected in January.

Late last week, Diamond Aircraft selected a more powerful version of the Williams FJ33 turbofan–the FJ33-4A-19–for its single-engine D-Jet. With 1,900 pounds of thrust versus 1,564 pounds for the originally planned FJ33-4A-15, the more powerful engine offers “a potential future performance upgrade path” for the very light jet.

Hawker Beechcraft Beechjet 400A, Norfolk, Va., June 14, 2006–The NTSB said the probable cause of the dual engine flameout was the accretion of high-altitude ice crystals on the compressor vanes and their ingestion into the engine high-pressure compressor when the pilots pulled back the power levers. This caused compressor surges and the flameouts of both engines.

Though still without a launch program for its new 9,500- to 12,000-pound-thrust engine, Snecma has reported good progress in development work for its new Silvercrest powerplant series for large business jets and small regional airliners. As of
the end of January, the French manufacturer had completed 35 hours of combustion testing since starting work on this phase of the $100 million development on Nov. 30, 2007.

Among the turbine engine programs Honeywell is featuring at Booth No. 2137 this week are a completely factory-remanufactured version of the venerable T53 that powered the Huey series and the brand-new HTS900 turboshaft for the Army Bell ARH-70A armed reconnaissance helicopter.

Pratt & Whitney Canada’s helicopter turboshaft engine business has enjoyed
an unprecedented surge in recent years, thanks in part to the company’s development work on turbofan engines for business jets, company executives said.

Pratt & Whitney insists its geared turbofan (GTF) engine will have “fuel burn parity” with the competing open-rotor designs being studied by CFM International, Rolls-Royce and Snecma, all of whom have rejected geared fans as the way forward.

Honeywell Engines has adop-ted a pioneering role in the U.S. Army’s Small Heavy Fuel Engine (SHFE) development program, an advanced joint program started five years ago to develop and demonstrate turboshaft engines in the 700-shp class. The program has sought to achieve a number of lofty goals including a 20-percent reduction in specific fuel consumption, a 50-percent power-to-weight improvement and a 35-percent reduction of life-cycle costs.
