Rolls-Royce says Pearl 10X testing is going well

* Rolls-Royce says testing on the Pearl 10X is going well. The Advance 2 demonstrator has operated for over 1,000 hours.

* The Pearl 10X equips the Dassault Falcon 10X which should be delivered to customers in 2025.

* Rolls-Royce’s announcement follows Dassault Falcon’s press conference where the manufacturer said it had started producing parts for the first Falcon 10X.

* The Pearl 10X will be able to run on 100% sustainable aviation fuel.

* Dr Dirk Geisinger, director of business aviation at Rolls-Royce, said: “The Pearl 10X’s combination of highly efficient power and exceptional environmental performance is in a class of its own and will help the Falcon 10X to Dassault to set new standards in the field. very long-range business jet market.

Press release

The Rolls-Royce Pearl® 10X engine development program is progressing well and has successfully accumulated more than 1,000 hours of testing, both on the Advance 2 demonstrator and on the Pearl 10X engine configuration.

The first dedicated Pearl 10X test engine ran for the first time earlier this year and exceeded its target thrust levels on the first test, making it the most powerful business aviation engine in the Rolls portfolio -Royce. All tests conducted so far have proven the reliability of the engine and shown that it will meet the performance requirements to power Dassault’s flagship Falcon 10X.

The Pearl 10X is the newest member of the advanced Pearl family of engines and the first Rolls-Royce engine to power a business jet from the famous French aircraft manufacturer. Dassault’s choice of the Pearl 10X for its new top-of-the-range product is further proof of Rolls-Royce’s position as the engine manufacturer of choice in business aviation.

The development program to date has included rigorous testing of the new ultra-low emissions ALM combustor, compatible with 100% Sustainable Aviation Fuel (SAF) and the new accessory gearbox, which allows for higher additional power extraction. One of the next steps will be the first complete powertrain, including its bespoke Spirit nacelle, EBU and mounting system, which will enter the testing program later this year.

Dr Dirk Geisinger, Director of Business Aviation at Rolls-Royce, said: “Our Pearl 10X team is extremely focused on engine development and I am proud to see the continued progress of the program. The Pearl 10X’s combination of highly efficient power and exceptional environmental performance is in a class of its own and will help Dassault’s Falcon 10X set new standards in the ultra-long-range business jet market.

The Pearl 10X takes the Advance2 engine core, the most efficient core available in the business aviation industry, and combines it with a high-performance low-pressure system, resulting in superior thrust of more than 18,000 lbf. Compared to the latest generation of Rolls-Royce business aviation engines, the Pearl 10X offers 5% higher efficiency, while delivering exceptional low noise and emissions performance. The result is an engine that delivers a market-leading combination of power and efficiency. This combination will allow customers and operators to have premium accessibility at the airport and perform ultra-long distance connections while being able to travel almost as fast as the speed of sound.

It combines innovative technologies derived from the Rolls-Royce Advance2 demonstration program and proven features from the Pearl family to deliver world-class environmental performance. This includes an ultra-efficient fan; a high-pressure compressor with an industry-leading pressure ratio and six blisk stages; an ultra-low emissions combustion chamber; a two-stage shroudless high-pressure turbine as well as an upgraded four-stage low-pressure turbine that is one of the most efficient and compact in the industry. This suite of technologies is packaged in an all-new ultra-thin pod from Spirit AeroSystems.
