Rolls-Royce recently received FAA approval for its BR700-730B2-14 engine, known commercially as the Pearl 700, that powers the soon-to-be-certified Gulfstream G700 and G800 ultra-long-range twinjets. EASA gave its nod for the engine last September.
Developed at the Rolls-Royce Center of Excellence for Business Aviation Engines in Dahlewitz, Germany, the Pearl 700 incorporates the engine-maker’s Advance2 engine core with a new low-pressure system. This results in an 8 percent increase in takeoff thrust, to 18,250 pounds, compared with the predecessor BR725 engine. Rolls-Royce said the engine also provides a 5 percent efficiency improvement while keeping down noise and emissions.
Gulfstream opted for the same engine for both its 7,750-nm G700 and 8,000-nm G800, which are slated for certification and service entry in the upcoming fourth quarter and mid-2024, respectively. “The certification of the Rolls-Royce Pearl 700 engines for the G700 and G800 is a significant step that brings us closer to delivering these game-changing aircraft to our customers,” said Gulfstream president Mark Burns, adding the company has received a “high level of demand” for both models
