  1. Final Presentation Back-up SlidesOrbital Transfer Vehicle (OTV) Power and Thermal Control Ian Meginnis Ian Meginnis Power Systems

  2. OTV Power Subsystems Solar Array <200V Solar Array Acronym Definitions: PCDU - Power Conditioning and Distribution Unit PPU - Power Processing Unit LL - Lunar Lander DC - Direct Current Note: Not to scale Ian Meginnis Power Systems Battery (LL) Individual OTV Components DC-DC Converters PCDU 100V 100V PPU (Electric Propulsion)

  3. 100g Payload Case Power Budget 10kg Payload Case Power Budget Large Payload Case Power Budget Ian Meginnis Power Systems

  4. Power Distribution: 100g Payload OTV Power Distribution: 10kg Payload OTV Power Distribution: Large Payload OTV Ian Meginnis Power Systems

  5. OTV Power Dimensions Ian Meginnis Power Systems

  6. OTV Thermal Control (all payloads) Electronics Board Thermal Control Hall Thruster Thermal Control Acronym Definitions: PCDU - Power Conditioning and Distribution Unit PPU - Power Processing Unit Batt - Battery DC - Direct Current Note: Not to scale Ian Meginnis Power Systems Radiating Heat Shroud Radiating Heat Shroud (Exhaust) 2 Radiators Hall Thruster DC/DC Converter PPU PCDU Batt Aluminum Heat Pipes with Ammonia Aluminum Mount

  7. OTV Electronics Thermal Control Ian Meginnis Power Systems

  8. Single, Simplified Orbit of OTV (Large Payload) Moon • At least 1 of the OTV’s set of radiators will not be exposed to sun’s rays at any point during the trajectory • Each radiator, alone, can provide thermal control for OTV electronics Sun Earth Note: Not to scale Ian Meginnis Power Systems
