CFM hails design review milestone as RISE arises
CFM International's RISE open-fan engine demonstrator has passed its preliminary design review (PDR).
TL;DR
The PDR covers the compact core, open-fan, and outlet guide vanes, allowing the joint venture to begin manufacturing parts for a ground-test demonstrator scheduled for later this decade. The RISE program is a key pillar in developing next-generation narrowbody propulsion, aiming for significant improvements in fuel efficiency and durability.
