Features - Rolls-Royce Pearl® 10X engine , that is going to Power Dassault’s Falcon 10X

The Rolls-Royce Pearl^® 10X !

Yesterday-6th May , Dassault chose Rolls-Royce Pearl^® 10X, for its  Brand New Falcon 10X aircraft  that is set to enter the market by 2025.

So, what features are expected from this customized engine , that Rolls-Royce claims to be the third and most powerful of Pearl series ?  

• More than 18,000 Lbs thrust.
• Advance2 engine core
• 5% SFC reduction.
• 100% SAF tested

The Pearl 10X features the Advance2 engine core, the most efficient core available across the business aviation sector, and combines it with a high-performance low-pressure system, resulting in a superior thrust of more than 18,000lb.

What is Advance2 Core ?

Advance2 engine core is a New design for 2-shaft jet engines that combines new core designs and LP systems that can improve SFC performance and an OPR of 50:1, while future-proofing on noise and emissions requirements.

Compared to Rolls-Royce’s last generation of business aviation engines the Pearl 10X offers a 5% higher efficiency, while delivering outstanding low noise and emissions performance.

This combination will enable customers and operators to have premium airport accessibility and fly ultra-long-range connections whilst also being able to travel nearly as fast as the speed of sound.

It brings together innovative technologies derived from the Rolls-Royce Advance2 demonstrator programme and proven Pearl family features to deliver world-class environmental performance.

The Engine !

• A highly-efficient blisked fan.
• A high pressure compressor with a market-leading pressure ratio and six blisked stages.
• An ultra-low emissions combustor;
• A two-stage shroudless high pressure turbine .
• Enhanced four-stage low pressure turbine .
• 3D-printed combustor tiles, manufactured by an advanced Additive Layer Manufacturing process.

A new-generation Engine Health Monitoring System that introduces advanced vibration detection, the Pearl family benefits from the incorporation of advanced remote engine diagnostics. 

The Nacelle !

The Rolls-Royce Pearl 10X engine will get the housing in a brand new, ultra-slimline nacelle from Spirit AeroSystems.

Development Stage

The engine is being developed at the Rolls-Royce Centre of Excellence for Business Aviation Engines in Dahlewitz, Germany, and is currently undergoing a comprehensive test programme, which includes the capability to operate on 100% Sustainable Aviation Fuels.

The Pearl engine family is part of the Rolls-Royce IntelligentEngine vision of a future where product and service become indistinguishable due to advancements in digital capability.
