Dimidium

Overview

The Regenerative Engine (Dimidium) project aims to develop a liquid bipropellant rocket motor that is regeneratively cooled by its fuel, allowing it to burn for extended periods of time without disposable components like ablative liners. This will be accomplished by embedding coolant channels into the nozzle and combustion chamber walls through a process called electroforming, where channels are machined into an inner copper wall and a specialized solution is used to plate a nickel outer wall on top, resulting in channels sandwiched between the two walls.
