Gulfstream G700 Development Accelerates

SAVANNAH, Georgia, May 8, 2020 — Gulfstream Aerospace Corp. today announced the second and third all-new Gulfstream G700™ test aircraft have taken flight, further advancing toward certification and customer deliveries of the industry’s new flagship.

The second G700 flight-test aircraft had its first voyage on March 20, departing Savannah/Hilton Head International Airport (SAV) and flying for 2 hours and 58 minutes. The aircraft reached an altitude of 45,000 feet/13,716 meters and a speed of Mach 0.85. Also departing from SAV, the third flight-test aircraft flew for the first time today, soaring over Savannah for 3 hours and 2 minutes. It also reached an altitude of 45,000 ft/13,716 m and a speed of Mach 0.85.

“The G700 flight-test program is running very well, a reflection of the extensive testing we conducted in our ground labs,” said Mark Burns, president, Gulfstream. “All three flight-test aircraft are performing exactly as we expected them to, and that helps us ensure a safe and thorough certification of the highest performing, most spacious and technologically advanced aircraft in business aviation.”

The three flight-test aircraft have flown more than 100 hours since the program’s first flight on Feb. 14. The G700 has reached a maximum altitude of 54,000 ft/16,459 m and a maximum speed of Mach 0.94.

The current flight-test aircraft are being used for envelope expansion, flutter testing, flying qualities and flight control, as well as mechanical systems, flights into known icing and environmental control systems, among other tests.

The G700 features the longest, widest and tallest cabin in the industry with 20 Gulfstream panoramic oval windows and up to five living areas, along with an ultragalley with more than 10 feet of counter space and a crew compartment or passenger lounge; a master suite with shower; and the industry’s only ultrahigh-definition circadian lighting system.

The G700 is powered by Rolls-Royce Pearl 700 engines and can fly at its high-speed cruise of Mach 0.90 for 6,400 nautical miles/11,853 kilometers or at its long-range cruise of Mach 0.85 for 7,500 nm/13,890 km. The G700 also includes the Gulfstream Symmetry Flight Deck™ with the industry’s only electronically linked active control sidesticks; the most extensive use of touch-screen technology in business aviation; and Gulfstream’s award-winning Predictive Landing Performance System.      

Most Powerful Rolls-Royce Business Aviation Engine’s Takes To The Skies For The First Time

Two Rolls-Royce Pearl 700 engines have successfully powered the brand new Gulfstream G700 to the skies for the first time. The purpose-designed engine, the most powerful in the Rolls-Royce business jet propulsion portfolio, is the exclusive powerplant for Gulfstream’s flagship aircraft, the world’s most spacious business jet. 

The Gulfstream G700, which used a 30/70 blend of sustainable aviation fuel for this first flight, took off from Gulfstream’s headquarters in Savannah, Georgia, USA, at 1:19 p.m. local time and landed 2 hours and 32 minutes later. The aircraft and its engines will now undergo an intensive flight test programme ahead of certification. 

Dr. Dirk Geisinger, Director – Business Aviation, Rolls-Royce, said: “This is a truly great moment for all of us and we are very proud. The cutting-edge Pearl 700 is a perfect fit for the Gulfstream G700 and will help the aircraft deliver an unrivalled combination of ultralong-range, speed and performance. We have already achieved more than 1,500 testing hours and 5,000 cycles, and we are fully committed to supporting the G700 flight test programme.”

With more than 3,200 business jets in service today powered by Rolls-Royce engines, the company is the world’s leading engine supplier in this market. The Pearl 700 is the newest member of the state-of-the-art Pearl engine family, first introduced in 2018, and marks the seventh new civil aerospace engine introduced by Rolls-Royce over the past decade. Gulfstream’s selection of the Pearl 700 to power its new flagship aircraft reaffirms Rolls-Royce’s position as the leading business aviation engine manufacturer. The engine was developed at the Rolls-Royce Centre of Excellence for Business Aviation Engines in Dahlewitz, Germany.

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 8 per cent increase in take-off thrust at 18,250lb compared to the BR725 engine. The engine offers a 12 per cent better thrust-to-weight ratio and 5 per cent 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 the aircraft nearly as fast as the speed of sound (Mach 0.925).

It brings together innovative technologies derived from the Rolls-Royce Advance2 technology demonstrator programmes with proven features from the Rolls-Royce BR700, today’s leading engine family in business aviation. This includes a highly-efficient 51.8” blisked fan, a high pressure compressor with a market-leading pressure ratio of 24:1 and six blisked stages, an ultra-low emissions combustor, a two-stage shroud-less high pressure turbine and an enhanced four -stage low pressure turbine, that is one of the most efficient and compact in the industry.

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 our customers.
