Rolls-Royce Pearl

The engine was flown on more than 25 missions over a six-month period starting in late March.

Rolls-Royce has delivered the first Pearl 10X engines to Dassault as the French aircraft-maker readies its Falcon 10X for first flight.

The two companies are studying Pearl-family business jet engines as an option to power military uncrewed aerial systems.

Rolls-Royce Germany has teamed up with ITP Aero to offer a new engine family for collaborative combat aircraft (CCA) that will lean on the proven Advance2 core.

Flying with three engine types, Rolls’ unusually configured testbed is designed for high-altitude evaluation of the Pearl 10X for Dassault’s long-range Falcon.

Flight tests of the Rolls-Royce Pearl 10X engine for the ultra-long-range Dassault Falcon 10X business jet have begun following delivery of the company’s Boeing 747-200 flying testbed fitted with the test engine to its Tucson facility in Arizona.

Dassault executives say final assembly of the first ultra-long-range Falcon 10x is expected to begin in the second half of 2024.

The core from Rolls-Royce's Pearl family of business jet engines could power the remote carriers that will operate as a component of FCAS.

With long-awaited certification of the ultra-long-range G700 seemingly imminent, Gulfstream is using Dubai Airshow as the jumping-off point for a six-week tour.

The engine surpassed the target thrust levels on its very first run.

The tests were conducted at the German Aerospace Center DLR Cologne facility.

Rolls-Royce is expanding research into hydrogen-fueled aviation and the company has recently launched a hydrogen technology program.

Rolls-Royce plans to run back-to-back tests of a Pearl 10X turbofan with Jet A and SAF to check emissions and validate progress.

After surpassing target thrust levels on its first test run, Rolls says the first Pearl 10X is now ready to go on its Boeing 747-200 flying testbed.

Engine-makers are accelerating tests of business aircraft engines with 100% sustainable aviation fuel.
