(Self-Deployable Habitat for Extreme Environments) ELECTRIC PUMPS for Rocket Engines ⊲ Uses high-speed electric motor to drive the pump instead of a turbine ⊲ Design based on 30 years of experience with rotating machines ⊲ Enables substantially simplified rocket engine architecture ⊲ Innovative sealing – MMH, NTO, H2O2 pump ⊲ Green propellants applications ⊲ Fluid dynamic bearings The advancements in power electronics and bearing technology allow for a new way of thinking about the propellant feed in rocket engines. The highly efficient high-speed electric pump enables to decouple the challenging design difficulties of the turbopump while providing new possibilities in engine regulation and throttling. The benefits are apparent in micro and small launchers application as well as in larger spacecrafts and landers. E-Pump Cycle Rocket Engine battery (DC source) fuel oxidizer g n li o o c e l z z o n REGULATING VALVES for 100 kN throttleable lox-methane expander engine ⊲ Standard space rated interfaces ⊲ Electronic control for regulation ⊲ Precise control and regulation characteristics ⊲ Flow-optimized, mass-optimized, cost-optimized Location of Regulating Valves Main Fuel Valve Turbopump Bypass Regulation Regulating valves developed for liquid- propellant rocket engines are subject to demanding standards concerning perfect technological qualities and engineering reliability. Regulating valves with electromotor actuators provide strict control over propellant feed. This enables state-of- the-art engine throttling. Valves are developed together with the necessary electronics controller. Furthermore, the developed engine main fuel valve is designed to provide extremely low losses at a challenging propellant flow rate.
