The Rolls-Royce AE 1107C-Liberty engine has powered the unique V-22 Tilt-rotor aircraft to 500 flight hours in just one year and one day since return to flight-testing, averaging 40 hours a month of flying. This most recent success caps a seven-month period during which the engine team has won a prestigious award, secured new business and achieved a significant delivery milestone.
At the beginning of the month, the Rolls-Royce AE1107C-Liberty support team recently received the American Helicopter Society's (AHS) Supplier Excellence Award for its outstanding quality, innovativeness and cost effectiveness in support of the V-22 program. The support team accomplished numerous risk reduction efforts including detailed installed engine final inspections, engine test runs and increased resource management to ensure a smooth return to flight.
The support of the AE1107C-Liberty is provided under the Rolls-Royce Power by the Hour (PbtH) contract. This contract is administrated commercially with the underlying goal of increasing engine reliability and maximizing engine on-wing time.
Earlier this year, Rolls-Royce was awarded two contracts from the U.S. Department of Defense (DoD) worth a total of $50 million for the procurement of 22 engines for the V-22 aircraft and for engineering, manufacturing and development work.
In December 2002, the company delivered its 100th AE 1107C engine, and is scheduled to deliver 23 engines during 2003 in support of the aircraft's low rate initial production.
Development of the 6,000 shaft horsepower AE 1107C was begun in the mid-1980s. It was flight-rated by the U.S. Navy in 1988 and was certified by the Federal Aviation Administration in 1998. The AE 1107C is the cornerstone of the Rolls-Royce common core family of engines, which includes the AE 2100 turboprop and AE 3007 turbofan.
Rolls-Royce was the first turbine engine manufacturer to develop three separate and distinct engine lines based around a common power core. More than 3,200 of these engines have been delivered to both military and civil operators and together; they have accumulated nearly six million flight hours.
Rolls-Royce has a broad customer base comprising more than 500 airlines, 4,000 corporate and utility aircraft and helicopter operators, 160 armed forces and more than 2,000 marine customers, including 50 navies. The company has energy customers in nearly 120 countries. Rolls-Royce employs around 37,000 people, of which 22,000 are in the UK. Forty per cent of its employees are based outside the UK - including 5,000 in the rest of Europe and 8,000 in North America.
Annual sales total nearly Â£6 billion, of which over 40 per cent currently comes from aftermarket services. The order book stands at more than Â£17 billion, which, together with aftermarket demand, provides visibility as to future activity levels.
