Rolls-Royce (LSE: RR., ADR: RYCEY) made a statement about the Pearl 10X engine development program at the European Business Aviation Congress and Exhibition (EBACE) in Geneva. It was noted that the program is progressing rapidly, and the successful tests carried out on both the Advance 2 demonstrator and the Pearl 10X engine configuration exceeded 500 hours. Preparations are also underway for the flight tests that will begin this year on Rolls-Royce's private Boeing 747 test bed.
The newest member of the Pearl engine family, the Pearl 10X is the first Rolls-Royce engine to power the Dassault Falcon 10X business jet. The French aircraft manufacturer's choice of the Pearl 10X for its new high-class aircraft once again reveals that Rolls-Royce is a preferred engine manufacturer in commercial aviation.
Proving its reliability in all tests completed to date, the Pearl 10X meets Dassault's performance criteria to power its pioneering Falcon 10X aircraft.
As part of the development program, tests of the new ultra-low emission ALM combustion chamber, compatible with 100% Sustainable Aviation Fuel (SAF), and the new gearbox that allow higher additional power extraction were also carried out. The engine, which managed to exceed the planned levels during its first test, aims to be the most powerful commercial aviation engine in the entire Rolls-Royce portfolio. Made to order, the Spirit chassis was first put into operation in 2023 with the entire power unit, including the engine interface systems (EBU) and mounting system.
Equipped with the Advance2 engine core, the Pearl 10X combines this with a high-performance low-pressure system and delivers more than 18 lbf of power. The Pearl 10X offers 5% higher efficiency compared to the previous generation Rolls-Royce commercial aviation engines, while providing exceptionally low noise and emission performance. This offers a market-leading combination of power and efficiency. This combination also aims to enable customers and operators to access world-class airports, fly on ultra-long-range connections and travel at near the speed of sound.
Offering world-class environmental performance, Pearl 10X combines innovative technologies from the Rolls-Royce Advance2 program and Pearl family features. Pearl 10X engine; It has efficient fan blades, market-leading pressure ratio, and a six-stage disc and blade high-pressure compressor. The engine also incorporates a low-emission, two-stage high-pressure turbine. One of the most efficient and compact turbines in the industry, the Pearl 10X is housed in Spirit AeroSystems' new ultra-slim chassis.
Rolls-Royce's Senior Vice President, Dassault, Dr. Phillip Zeller said:
“As a team, we are fully focused on the development of this engine. We are proud to see the program continually progress and achieve important goals. A unique engine in its class with highly efficient power and environmental performance, the Pearl 10X will help Dassault's Falcon 10X aircraft set new standards in the ultra-long-range business jet market. We look forward to delivering the first engines for flight testing. We look forward to seeing the first flight of our engine.”
On the other hand, the construction of Rolls-Royce's new production support facility of 2 square meters in Le Haillan, near Bordeaux, France, continues. Close to Dassault's final assembly line in Merignac, this facility will play an important role in supporting the flight testing and production activities of the Dassault Falcon 10X aircraft. The facility, which will consist of workshops, warehouses and offices, will host approximately 30 employees.
