  1. 1. <ul><li>G.A.S. P.U.M.P. Architecture & Its Optimization: Storage </li></ul>
  2. 2. Content Menu
  3. 3. 1.0 Introduction
  4. 4. 2.0 Challenges and Potential Solution
  5. 5. 3.0 Short-Term Solution <ul><li>Address the pioneers explorers ( 2020-2040) </li></ul>
  6. 6. 3.1 modified LSAM solution <ul><li>LSAM = Lunar Surface Access Module </li></ul>The Lunar Surface Access Module (LSAM) is the planned American moon landing vehicle that will allow astronauts to land there around 2020 as part of NASA's Project Constellation.
  7. 7. Modified LSAM Solution (All-Terrain Hex-Legged Extra-Terrestrial Explorer
  8. 8. Why LSAM module ?
  9. 9. 4.0 Long-Term Solution <ul><li>Based on Next phase of short-term solution and addressing next generation of lunar explorer </li></ul><ul><li>IN PROGRESS </li></ul>
  10. 10. 5.0 Current Status
  11. 11. 5.0 Our timeline
  12. 12. <ul><li>G.A.S. P.U.M.P. Architecture & Its Optimization: Storage </li></ul>
  13. 13. Storage System Optimization <ul><li>STORAGE TANK OPTIMIZATION </li></ul><ul><li>It compares different storage options for long term </li></ul><ul><li>Tool used - decision matrix to select the most optimized tank solution </li></ul><ul><li>All systems compared using important criteria ( Cost & Durability ) and then ranked based on its total score </li></ul><ul><li>Next phase: weighted decision matrix based on drivers </li></ul>
  14. 14. Liquid Oxygen
  15. 15. Liquid Hydrogen
  16. 16. Water <ul><li>Liquid or Solid (Ice) </li></ul><ul><li>Least pressure on containment vessel </li></ul><ul><li>Higher Density for Hydrogen </li></ul><ul><li>Life Support Systems </li></ul>
  17. 17. Storage System
  18. 18. Tank Materials
  19. 19. Thermal Management
  20. 20. Location <ul><li>Environmental Considerations </li></ul><ul><li>OPTIONS: </li></ul><ul><ul><li>Surface </li></ul></ul><ul><ul><ul><li>Day temp (107 to 123 deg C) </li></ul></ul></ul><ul><ul><ul><li>Night temp (-153 to –233 deg C) </li></ul></ul></ul><ul><ul><ul><ul><li>Permanently shadowed craters allow for less energy expenditure for cooling </li></ul></ul></ul></ul><ul><ul><li>Sub Surface </li></ul></ul><ul><ul><ul><li>Avg. Temp at 1m depth (-35 deg C) </li></ul></ul></ul>
  21. 21. Fixed Vs. Mobile
  22. 22. Interfaces (not yet researched) <ul><li>Assumed to be based on terrestrial designs. </li></ul><ul><li>Must be adaptable to different transportation systems. </li></ul><ul><li>Ideally standardized. </li></ul><ul><li>Must be resilient to leaks and contain a health monitoring system (leak detection) </li></ul>
  23. 23. Major Problems <ul><li>Hydrogen Leaks + Flammability </li></ul><ul><li>Long-term Storage (Oxidized parts) </li></ul><ul><li>Lunar Dust </li></ul><ul><li>Rapid Expansion (Asphyxiation) </li></ul><ul><li>High Pressure Gases (ruptures/explosions) </li></ul><ul><ul><li>Boil-off (Rocket Fuel Venting) </li></ul></ul>
  24. 24. Health Monitoring and Communication <ul><li>Sensors (which ones are vital?) </li></ul><ul><li>We need to address the communication infrastructure! (on some level) </li></ul><ul><li>Back-up power supplies </li></ul>
