Rolls-Royce has officially unveiled the Pearl 10X, the third and most powerful member of its market-leading Pearl engine family for the business aviation market. The engine has been optimised to exclusively power Dassault’s brand-new flagship aircraft, the Falcon 10X, which was revealed during a digital ceremony at Le Bourget airport in Paris.
The Pearl 10X features the Advance2 engine core and combines it with a high-performance low-pressure system, resulting in a superior thrust of more than 18,000lb. Compared to Rolls-Royce’s last generation of business aviation engines the Pearl 10X offers a 5% higher efficiency, while delivering outstanding low noise and emissions performance.
It brings together innovative technologies derived from the Rolls-Royce Advance2 demonstrator programme and proven Pearl family features. These includes a highly-efficient blisked fan; a high pressure compressor with a market-leading pressure ratio and six blisked stages; an ultra-low emissions combustor; a two-stage shroudless high pressure turbine as well as an enhanced four-stage low pressure turbine that is one of the most efficient and compact in the industry. This suite of technologies is all housed together within a brand new, ultra-slimline nacelle from Spirit AeroSystems.
The engine is being developed at the Rolls-Royce Centre of Excellence for Business Aviation Engines in Dahlewitz, Germany, and is currently undergoing a comprehensive test programme, which includes the capability to operate on 100% Sustainable Aviation Fuels.
One of the new key features of the Pearl 10X will be 3D-printed combustor tiles, manufactured by an advanced Additive Layer Manufacturing process. This pioneering technology, which supports the exceptional environmental performance of the engine, has been developed and extensively tested as part of our Advance2 programme.
Chris Cholerton, President Civil Aerospace, Rolls-Royce, said: “This is a very special day for Rolls-Royce and the dedicated Pearl team, who have been passionately working behind the scenes to make this programme a reality. We are extremely proud that Dassault has chosen us to power their flagship Falcon 10X, and I would like to congratulate the Dassault family as well as the Falcon team on this special occasion. Today marks the start of a successful partnership and, with our pioneering Pearl 10X engine and leading customer service, I look forward to supporting Dassault as they continue to impress their customers in the ultra-long-range corporate jet market.”
Eric Trappier, Chairman and CEO, Dassault Aviation, said: “The Pearl 10X is perfectly matched to our performance requirements for our new, ultra-long-range jet and proved itself to be the best solution also for reliability and efficiency. New technologies within its core and its digital controls make it the benchmark for powerplant technology in this business aviation segment.
Moreover, Rolls-Royce’s track record for product support ensures an outstanding customer service experience.”
