Rolls-Royce’s Pearl® 700 engine programme has successfully achieved further important test milestones on its way to certification and entry into service in 2022, reaching more than 8,000 test cycles and more than 3,000 testing hours. 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). Not even the global pandemic could stop the rigorous test regime – the medium bird strike test was performed with a novel remote set-up allowing key members of the team to join the test virtually. Test programme Pearl 700 engines have already powered Gulfstream’s new flagship aircraft G700 beyond its maximum operating speed The flight test programme started in February 2020 and is progressing very well with a fleet of five dedicated flight-test aircraft and one production-test aircraft. The advanced Pearl 700 engines are performing exceptionally well and have already powered Gulfstream’s new flagship aircraft G700 beyond its maximum operating speed and cruise altitude, flying nearly as fast as the speed of sound (Mach 0.99/1,220 kilometres per hour) while reaching an altitude of 54,000 ft/16,459 m. 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. During its first international visits to the Middle East and Europe, the aircraft set two city-pair speed records and a third speed record on its return trip to the United States. New technology and notable performance Dr. Dirk Geisinger, Director of Business Aviation, Rolls-Royce, said: “Seeing the Pearl 700 programme running at such a fast pace makes me really proud of the team behind it. In addition to the extensive ground testing, the flight test campaign is progressing exceptionally well." "Today, it stands at more than 3,000 engine flying hours from more than 2,000 engine flights and with the G700 test aircraft fleet in the air these numbers are increasing daily. The pioneering technology and the outstanding performance of the Pearl 700 support Gulfstream’s business aircraft in reaching new standards for the top end of the ultra-long-range corporate jet market.”
Rolls-Royce’s Pearl® 700 engines have been selected by Gulfstream to power the company’s latest ultra-long-range business jet, the G800. The engine type was purpose-designed for Gulfstream and is on track to receive its certification next year. It is the most powerful product in the Rolls-Royce business jet propulsion portfolio flying and the exclusive powerplant for the all-new Gulfstream G700 and Gulfstream G800. With more than 3,600 business jets in service today powered by Rolls-Royce, the company is the Number one engine supplier in this market. Delivering outstanding efficiency Dr. Dirk Geisinger, Director of Business Aviation, Rolls-Royce, said, “Our whole business aviation team is very excited about this latest success for our market-leading Pearl engine family and I would like to congratulate Gulfstream on this special occasion. The Pearl 700 is a pioneering product, that brings together our latest technology to deliver outstanding efficiency." "It is part of our commitment to reach net zero operations and has already proved its ability to run on 100% sustainable aviation fuel. We are now in the final phase of the engine certification programme and everybody at our team is fully committed to support a smooth entry into service of the Pearl 700 next year.” Enhancing customer purchase experience “Gulfstream is pleased with the performance capabilities of the Pearl 700 engine and excited to partner with Rolls-Royce for the longest-range aircraft we have produced,” said Mark Burns, President, Gulfstream. Rolls‑Royce’s after-market support also dovetails excellently with Gulfstream Customer Support “Gulfstream and Rolls-Royce have been doing business together since the Gulfstream I, introduced more than 60 years ago, and we know our customers will greatly benefit from the performance capabilities and efficiencies of these engines. Rolls‑Royce’s after-market support also dovetails excellently with Gulfstream Customer Support, further enhancing our customers’ ownership experience.” Features 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 18,250lb compared to the BR725 engine. The engine offers a five percent higher efficiency while maintaining its class-leading low noise and emissions performance. The result is an engine that is highly efficient, but also able to propel customers nearly as fast as the speed of sound (Mach 0.925). The engine’s pioneering technology, combined with outstanding performance, supports Gulfstream’s business aircraft in reaching new standards for the top end of the ultra-long-range corporate jet market. The engine has been developed at the Rolls-Royce Centre of Excellence for Business Aviation Engines in Dahlewitz, Germany, and is currently finalizing a comprehensive test and certification programme. Design Pearl family is supported by Rolls‑Royce CorporateCare Enhanced, the overall service programme Designed for outstanding reliability, the Pearl family is supported by industry-leading Rolls‑Royce CorporateCare® Enhanced, the most comprehensive service programme in business aviation. CorporateCare Enhanced offers substantial financial and operational benefits to customers, increasing asset value and liquidity, mitigating maintenance cost risk and protecting against the unforeseen costs of unscheduled events anywhere in the world. Increased aircraft availability, reduced management burden, full risk transfer, direct priority access to the Rolls-Royce services infrastructure and remote site assistance are further customer benefits. The Pearl engine family is part of the Rolls-Royce IntelligentEngine vision of a future where product and service become indistinguishable thanks to advancements in digital capability. As well as a new-generation Engine Health Monitoring System that introduces advanced vibration detection, the family benefits from the incorporation of advanced remote engine diagnostics. It is also enabled for bi-directional communications, allowing for easy remote reconfiguration of engine-monitoring features from the ground. Cloud-based analytics, smart algorithms and Artificial Intelligence continue to play an increasing role in delivering exceptional levels of availability and greater peace of mind for the customers.
