Rockets range in size from fireworks so small that ordinary people use them to immense Saturn Vs that once propelled massive payloads toward the Moon. Whilst Additive Manufacturing is undoubtedly having a huge impact on the design and manufacture of rocket propulsion systems, most notably combustion chambers and nozzles, the Achilles’ heel of most AM processes is as-built surface finish. Although the lead is 1000*C, the fusion products would be much hotter, so the Isp would be limited only by the engine parts exposed to rocket exhaust. This process was applied to the third stage spur bull gear and mating pinions along with the second stage bevel gears of a Sikorsky S-76+ main gearbox. For a rocket, the accelerated gas, or working fluid, is the hot exhaust produced during combustion.
