General aviation turboshaft Pearl 10X

Overview
The Pearl 10X is a business aviation turbofan engine developed by Rolls-Royce to power the Dassault Falcon 10X. It pairs the Advance2 engine core with a high-performance low-pressure system to provide target thrust above 18,000 lbf while improving fuel efficiency. The engine has completed an extensive test programme and is certified to operate on 100% Sustainable Aviation Fuel (SAF).

Key statistics
Thrust (lbf): >18,000
SFC reduction: ~5%
SAF tested: 100%
