Rolls-Royce receives EASA cert for Pearl 700
Rolls-Royce’s Pearl 700 engine, exclusive to Gulfstream G700 and G800 aircraft, has received official certification by the European Union’s Aviation Safety Agency (EASA).
The engine was designed at the Rolls-Royce Centre of Excellence for Business Aviation engines in Dahlewitz, Germany, to enable Gulfstream’s latest aircraft to fly ultra-long-range missions “nearly as fast as the speed of sound”.
During testing, the engine performed well at sea-level and altitude conditions using both conventional jet fuel and 100% Sustainable Aviation Fuel (SAF). It withstood bird-strike, ice, hail and water ingestion and passed the critical fan blade containment test.
Dr Dirk Geisinger, director, Business Aviation, Rolls-Royce said the certification demonstrates the company’s “unique capabilities to design test, build and certify pioneering aircraft engines”. He added: “It also reflects the dedication of our global team to support Gulfstream and the entry into service of the G700 and G800.”
Mark Burns, president, Gulfstream said: “With these powerful advancements, Gulfstream customers can reap the benefits of large cabins with enhanced comfort over the worldwide flights the G700 and G800 can accomplish.”
The Pearl 700 combines the Advance2 engine core with a new low-pressure system, resulting in 8% increase in take-off thrust at 18,250lbf compared with the BR725 engine. The engine is said to give 5% higher efficiency while maintaining low noise and emissions performance.
In May this year, Rolls-Royce said testing on the Pearl 10X, which is due to be delivered to Dassault Falcon 10X customers in 2025, was going well.
