Rolls-Royce Pearl 700 engine unveiled

Rolls-Royce Pearl 700 engine unveiledRolls-Royce has unveiled the Pearl 700, which is the latest addition to its Pearl engine family for business aviation.

This purpose-designed engine — the most powerful in the Rolls-Royce business jet propulsion portfolio — is the exclusive power plant for the new Gulfstream G700.

With more than 3,200 business jets in service today powered by Rolls-Royce engines, the company is the world’s leading supplier of engines to this market.

The Pearl engine family was launched in 2018 (www.rolls-royce.com), and the Pearl 700 is the seventh new civil aerospace engine introduced by Rolls-Royce over the past decade.

The latest engine combines the Advance2 engine core — the most-efficient core available in the business-aviation sector — with a brand-new low-pressure system, resulting in an 8% increase in take-off thrust (at 18,250lb) compared to the BR725 engine.

It also offers a 12% better thrust-to-weight ratio and 5% higher efficiency, while maintaining its class-leading low-noise and low-emissions performance.

The result is an engine that is highly efficient and can travel nearly as fast as the speed of sound (Mach 0.925).

It combines innovative technologies derived from the Rolls-Royce Advance2 technology demonstrator programmes and proven features from the Rolls-Royce BR700 engine family.

It was developed at the Rolls-Royce Centre of Excellence for Business Aviation Engines in Dahlewitz, Germany, and is currently undergoing a comprehensive test programme.

Chris Cholerton, Rolls-Royce president (civil aerospace), said: “Our whole team is very proud to power the very latest Gulfstream aircraft — the G700 — and we are looking forward to a successful partnership that started some 60 years and 4,500 engine deliveries ago with the Dart-powered Gulfstream I.

"The Pearl 700 is a pioneering product that delivers outstanding efficiency, supporting our leading position in the business-aviation world.”
