Introduction

September 15, 2016, ©. Leeham Co: In Part 3 of this series, we identified the type and size of wing we would have on a new Russian-Chinese wide-body. It's now time to go through all the considerations around the engines for the aircraft.

The aircraft would enter the market around 2025. We would have to decide on what size engine that would be needed, what engines would be available at the time and could this project motivate any new engine developments.

Summary:

• The Russian-Chinese wide-body as outlined would require engines in the size class of the Boeing 787-9/10.
• GE and Rolls-Royce have been mentioned as engine suppliers. The question would be: will they offer updated 787 engines or new designs and will Russia compete with its announced engine project for the aircraft?
