The CR929 is sized to use engines from the Boeing 787 project. Both GE Aviation and Rolls-Royce got Request for Proposals (RFPs) on 22 Dec. 2017. In addition, the Russian and Chinese engine industry wants to develop an engine for the project.
The Chinese and Russian widebody program needs engines in the 75,000lbf thrust class.
The project's engine specification is closely modeled after the engines available from the Boeing 787 project.
In addition to the available 787 engines, the Chinese and Russian engine industry is trying to unite behind a joint engine proposal.
