Your bell design at least externally is too linear. Hyperbolic curves are recommended for optimal, fuel, efficiency, and exhaust pressure I would look into your geometry internally as well if it's externally that linear then it's either too heavy or designed wrong

From factory floor to launch site, the Terran R program is gaining serious momentum. Here’s the latest from May across design, build, test, and launch: 🖌️ Design: 17+ component-level Critical Design Reviews completed—rapidly releasing simpler parts like trays and manifolds ahead of structural assembly. ⚒️ Build: The LOX dome was successfully loaded onto the CFSW for its second weld, and the stage 2 transfer tube is now being welded—key steps toward completing the second stage tank. 🔥 Test: Aeon R engine qualification officially kicked off Stennis Space Center with 11+ hot fires in the books in May. 🚀Launch: Cape Canaveral’s LC-16 saw construction milestones—like the completion of the east flume wall in the diverter pit. Plus, we welcomed Robin Petitprez as SVP of Manufacturing & Supply Chain, strengthening our ability to industrialize Terran R at scale.
