Abstract
Disclosed herein are various technologies pertinent to rocket engines, including injector, thrust chamber, and electrical turbopump devices that may be combined to provide a highly efficient rocket engine and methods of manufacturing such devices, such as additive manufacturing. The use of additive manufacturing techniques allows for injectors and thrust chambers with complex geometries that provide for more efficient engine operation, including, for example, thrust chambers with varying surface roughness within cooling passages thereof and injectors with multiple annular plenums.
