Architecture-levelValueProposition:freeingupthetradespace

Every pound saved may be traded for other mission-enabling applications

Architectural-level optimization may influence the selection of motors as compared to point-design optimization



GTM Slide - 21

CompoundEciency:Reducingnetacceleratedmass



Every pound of electric motor/generator-related mass reduction substantially reduces propellant mass at each successive propulsive event in an exploration mission.

Reducing energy needs and thermal rejection loads reduces mass of power and thermal rejection systems

Smaller motors package more efficiently, reducing structural mass

GTM Slide - 22

MissionDesignandthevalueofEciency:distance,durationandlogistics

! The further the exploration horizon is and the longer the mission, the greater the value of motor/generator efficiency.

! Reliability becomes increasingly valuable for longer duration missions ! Logistical supportability is impractical beyond LEO



GTM Slide - 23

Commonality,System-levelRobustnessandSustainability

Modular motors applied throughout the architecture may enable repurposing of in-situ components and use of common spares and tools

Crewmembers may train for familiarity with a reduced set of hardware

May reduce design and certification expenses



GTM Slide - 24

CONCLUSION
