According to Rolls-Royce (London, U.K.), its Pearl 10X engine development program to power Dassault Aviation¡¯s (Paris, France) flagship, the Falcon 10X, has made good progress, and has successfully cumulated more than 1,000 testing hours, both on the Advance 2 demonstrator and the Pearl 10X engine configuration. The engine¡¯s composite package, secured in Feb. 2022 by FACC AG (Ried im Innkreis, Austria), includes supply of the fan track liners, spinner and cable bushing for the turbofan engine.

The first dedicated Pearl 10X test engine ran for the first time earlier this year and surpassed its target thrust levels on the first test run, making it the most powerful business aviation engine in the Rolls-Royce portfolio, says the company. All testing conducted so far has proved the reliability of the engine and shown it will meet performance requirements.So far, the development program has included the rigorous testing of the new, ultra-low emissions ALM combustor, which is compatible with 100% sustainable aviation fuel (SAF) and the new accessory gearbox, which enables for higher additional power extraction. One of the next milestones will be the first full powerplant, including its bespoke Spirit AeroSystems (Wichita, Kan., U.S.) nacelle, EBU and mount system, entering the test program later this year.

¡°The combination of highly efficient power and outstanding environmental performance of the Pearl 10X is in a class of its own and will support Dassault¡¯s Falcon 10X in setting new standards in the ultra-long-range corporate jet market,¡± Dr. Dirk Geisinger, director business aviation, Rolls-Royce, emphasizes.

The Pearl 10X features an efficient Advance2 engine core, combined with a high-performance, low-pressure system, resulting in a thrust of more than 18,000 pound-force. Compared to the last generation of Rolls-Royce business aviation engines, the Pearl 10X offers a 5% higher efficiency, while delivering outstanding low noise and emissions performance.

The ¡°6th Annual Commercial Aero Engine Shanghai International Forum¡± (CAESH) will be held in the city of Shanghai on August 30th to 31st, 2022, focus on scientific and technological innovation-driven, integration of industry in-depth and with a number of domestic and foreign aero engines and aircraft host development units to focus on the ¡°aviation industry policies and market trends¡±, ¡°application of new renewable energy and hydrogen fuel¡±, ¡°advanced aero engine materials and processing technology¡±, ¡°global short-term supply chain coordination¡± and other hot topics, to build a high platform for aero engine technology exchanges, academic discussions and business cooperation.
