UK-based global major propulsion and power systems group Roll-Royce announced on Wednesday that it had successfully tested its latest generation of business jet engines using 100% sustainable aviation fuels (SAF). The power plants concerned are the Pearl 15 and the Pearl 10X. The former powers the Bombardier Global 5500 and Global 6500 aircraft, while the latter will power the Dassault Falcon 10X (the French airframer’s ultra-long-range flagship business jet). Rolls-Royce’s business jet engines are designed and built in Germany, and the tests took place in Dahlewitz, in that country, at the headquarters of Rolls-Royce Business Aviation. In addition to the 100% SAF tests on both engines, the company ran comparative tests on the Pearl 10X engine, running the same engine on 100% Jet A-1 fuel and on 100% SAF.
