LONDON – Gulfstream Aerospace announced on September 20 that the all-new Rolls-Royce Pearl 700 engines for the flagship Gulfstream G700 and long-range Gulfstream G800 have achieved European Union Aviation Safety Agency (EASA) certification.

Mark Burns, president, of Gulfstream said: “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.”

“We are seeing a high level of demand for both the G700 and G800, and they are set to lead the upper end of the ultralong-range distance segment with their unique combination of range, speed and cabin size”

RR Pearl 700

During the test campaigns, the Pearl 700 has proved its reliability and performance under extreme conditions, experiencing cold start temperatures, where fuel viscosity is comparable to honey.

The engine has performed equally well in hot conditions, successfully completing long, high-power endurance runs and high-cycle tests, and has successfully demonstrated that it can run on 100% Sustainable Aviation Fuel (SAF).

The Pearl 700 combines the Advance2 engine core, the most efficient core available across the business aviation sector, with a brand-new low-pressure system, resulting in an eight per cent increase in take-off thrust at 18,250lbf compared to the BR725 engine.

RR Pearl 700 offers a 12% better thrust-to-weight ratio and 5% higher efficiency while maintaining its class-leading low noise and emissions performance. All this while propelling customers nearly as fast as the speed of sound.

The result is an engine that is highly efficient, but also able to propel customers as fast as Mach 0.925. In typical operations, the G700 has a maximum operating speed of Mach 0.925 and a maximum cruise altitude of 51,000 ft/15,545 m, which allows it to fly above commercial air traffic and the weather in the troposphere.

– Receiving the EASA certification for our Pearl 700 engine makes us very proud, as it illustrates once again Rolls Royce’s unique capabilities to design, test, build and certify pioneering aircraft engines.

It also reflects the dedication of our global team to support Gulfstream and the entry into service of the G700 and G800. We have worked closely with EASA and Gulfstream to achieve this certification and I would like to thank them both for their support – said Dr. Dirk Geisinger, Director – Business Aviation, Rolls-Royce.

Gulfstream flagship G700

The G700 was introduced as the new industry flagship in October 2019. The program includes five already manufactured flight-test aircraft and a structural test article that has completed load testing.

The G700 features the longest, widest and tallest cabin in the industry with 20 Gulfstream panoramic oval windows and up to five living areas. The aircraft introduces many all-new interior differentiators, including an ultra galley with more than 10 feet of counter space and a crew compartment or passenger lounge, an ultra-high-definition circadian lighting system, speakerless surround sound and a master suite with shower.

The G700 is powered by Rolls-Royce Pearl 700 engines and refined with Gulfstream-designed aerodynamics and an all-new winglet. The aircraft can fly at its high-speed cruise of Mach 0.90 for 6,400 nautical miles/11,853 kilometres or at its long-range cruise of Mach 0.85 for 7,500 nm/13,890 km.

Gulfstream’s Longest-Range Aircraft

The G800 redefines what it means to go farther faster in a Gulfstream and offers even more time savings with its impressive range at high speed. New G800 offers customers the longest range in the Gulfstream fleet with its 8,000-nautical-mile/14,816-kilometer range at Mach 0.85 and 7,000-nm/12,964-km range at Mach 0.90.

Powered by high-thrust Rolls-Royce Pearl 700 engines and the Gulfstream-designed wing and winglet introduced on the Gulfstream G700, the G800 also features enhanced fuel efficiency and more city-pair capabilities.

Gulfstream G800 is designed to seat up to 19 passengers and offers up to four living areas or three living areas with crew compartments. It also features the signature Gulfstream Cabin Experience with 100% fresh, never recirculated air, whisper-quiet noise levels, industry-leading low cabin altitude and 16 Gulfstream panoramic oval windows.
