Cessna 208B Caravan, Globe, Ariz., July 22, 2005–The NTSB determined that the probable cause of the crash of Caravan N717BT was the fatigue failure of the compressor turbine stator vane, the liberation of vane material into the compressor turbine (damaging the turbine blades downstream) and the total loss of engine power.
Rolls-Royce has revealed exclusively to Aviation International News details of an entirely new family of two-shaft engines under development to power business jets and large regional aircraft.
No aircraft flies with MTU engines, and yet MTU is involved in one third of all aircraft engine programs. MTU is the largest independent maintenance provider for aircraft engines and is associated with the production in many major engine programs. It is also leading Europe’s NEWAC research program, aiming to develop a new-technology engine-core concept.
Confidence in Pratt & Whitney’s geared turbofan (GTF) program is such that company president Steve Finger is talking about a potential widebody application for the engine. “We’re looking at that for late next decade,” he told Aviation International News.
Having passed responsibility for an engine for the planned Bombardier C Series 110- to 149-seat jetliner to its U.S. parent, Pratt & Whitney Canada (P&WC) says time devoted to the exercise has not been wasted. Rather, it is contributing to work on a 10,000- to 14,000-pound-thrust design–dubbed X10–aimed at a future generation of large business and corporate jets.
The Franco-Russian Powerjet SaM146 turbofan engine, which is to power the Sukhoi Superjet 100 regional airliner, is set to fly by the end of this month. The first example of the 14,000- to 17,500-pound-thrust family made its first ground run in July 2006 at Rybinsk in Russia.
Visitors to Alenia Aermacchi, part of the Finmeccanica stand here at Le Bourget, will find the same M-311 lightweight jet basic/advanced trainer avionics demonstrator the company showed two years ago. However, the program has moved forward since then, with advancements in both the commercial and technical fields.
Phoenix-based engine and avionics manufacturer Honeywell says its 10,000-pound-thrust engine contender is well under way. Ron Rich, the company’s director of advanced technologies, told AIN that parts for the company’s HTF10000 demonstrator have already been ordered, with the core engine expected to be operational by the end of next year.
