New Lab member company, Launcher is developing the world’s most efficient rocket to deliver small satellites to orbit. ⁠ ⁠ Prototype 1: ⁠ This prototype was made with Inconel (a family of austenitic nickel-chromium-based superalloys), which does not have enough cooling properties to withstand the heat generated from the combustion process at its peak. ⁠ ⁠ Prototype 2: ⁠ The translucent prototype reveals the cooling channel, where a propellant is circulated through the model to ensure that the chamber can withstand the extreme heat produced during the combustion process.⁠ ⁠ Prototype 3: ⁠ The interstice in this prototype enables the team to inspect the embedded 3D printed cooling channels.⁠ ⁠ Prototype 4: ⁠ This prototype is 3D printed in copper which has high thermal conductivity to withstand a stronger heat flux. 3D printing the engine reduces cost, complexity, and manufacturing lead time.⁠ ⁠ #NewLab #Launcher #Rocket #FrontierTech⁠ launcherspace⁠
