An all-new RB3025 engine concept has been created by Rolls-Royce following a Boeing request also extended to General Electric and Pratt & Whitney for a powerplant for a future 777-size aircraft in around 2020. The current 777 is powered exclusively by the GE90.

Rolls-Royce has selected a 132.5-inch diameter for the composite fan for the 99,500-pound-thrust engine, which will sport a 12:1 bypass ratio and a 62:1 overall pressure ratio that would be the highest achieved on a commercial aircraft.

Engine manufacturers are here at EBACE providing a glimpse at where powerplant technology is going for business aviation with several clean-sheet designs or derivatives under development. Honeywell and Rolls-Royce each are working on two programs for business jets, while Pratt & Whitney Canada is involved in one. New players in the field–GE Honda and Snecma–each have a brand-new turbofan to promote, but the latter has yet to find

British safety officials have issued recommendations for flight-data recorders (FDRs) to record engine fuel-metering information and for reviews of landing-gear failure requirements and Boeing 777 data buffering. Accident investigators call for the action among nine safety recommendations in the final report of the Jan. 17, 2008, British Airways Boeing 777-236ER accident at London Heathrow Airport, which was released on Tuesday.

The NTSB has issued an “urgent” safety recommendation calling for a redesign of the Rolls-Royce RB211 Trent 800 Series engines in Boeing 777s after two separate reported incidents of thrust rollbacks due to ice accumulation on the engines’ fuel/oil heat exchanger (FOHE).

The FAA published a revised Airworthiness Directive today for Boeing 777-200s and -300s equipped with Rolls-Royce Trent 800 engines. The new AD adds further procedures to prevent ice buildup that can clog fuel lines.

European and U.S. regulators have agreed to mandate “aircraft level” action for Rolls-Royce Trent 800-powered Boeing 777s and are considering potential action for other certified aircraft/engine combinations. This follows recommendations in an interim UK Air Accidents Investigation Branch (AAIB) report published Thursday into the British Airways 777 accident at London Heathrow Airport in January.

Rolls-Royce and British Airways are embarking on a study to identify practical alternatives to jet fuel that would make real reductions to aircraft carbon footprints. The companies will initiate a joint tender process, inviting suppliers to offer alternative fuel samples for testing on a Rolls-Royce RB211 from a British Airways Boeing 747.
