  3. 1. Terrestrial Mineral Transportation Technologies Truck Train Capsule Pipeline Pneumatic Conveying Conveyor

  4. 2. The Lunar Environment

  5. ◆ Minerals in Lunar Regolith

  6. 1) Design factors 2) Transportation by vehicles 3. Transportation System for Lunar Regolith 3) Pneumatic transportation 4) PCP (Pneumatic Capsule Pipeline) 5) Electromagnetic drives 6) Maglev (Magnetic Levitation) 7) Propulsion system for Maglev 8) Lunar train 9) Concept

  7. ⇒For gaining high value output (He3, etc.) from Lunar regolith : Mining -> Transportation -> Extraction 1) Design Factors

  8. ◆ Issues 1. The surface is very soft. 2. There are a lot of craters on the moon’s surface. 3. Dust 2) Transportation by Vehicles ▶ Result: Therefore it is difficult to move by truck wheel on the surface with high speed.

  9. ◆ Applications Mail, hospital, bank (money) 3) Pneumatic Transportation ◆ Issues to consider for mineral “blowing” 1. Blower speed efficiency 2. Wear & tear due to friction (velocity of particles 15-20m/sec (54-72Km/hr) 3. Pipe sizing 4. Cyclone

  10. ◆ Advantages of pipeline 1) No pollution (noise, dust, spillage) 2) No traffic jam 4) PCP (Pneumatic Capsule Pipeline) ◆ Disadvantages (Used in Japan) 1) Low linefill rate (3%) Reasons of low linefill rate. ► Blowers block the passage of the capsules. ► In-line loading & unloading. 2) Low speed (9m/sec) => Traditional PCP is not economical.

  11. 5) Electromagnetic Drives ◆ Advantages 1. The linefill of CP systems with electromagnetic drive can be 15%, fivefold increase in comparison to PCP 2. Loading & unloading of capsules must be done outside the pipeline. 3. Velocity of capsules is about 15m/sec, higher than PCP (9m/sec). ▶ Result: CP is more economical system than PCP *Electromagnetic drives : LIM or LSM

  12. 6) Maglev (Magnetic Levitation) Maglev is using LIM or LSM system for propulsion. Electric traditional motor Linear motor Attraction Repulsion

  13. ◆ Maglev Overall Strengths Magnetic

  14. 7) Propulsion Systems for Maglev LIM LSM Stator Rotor Rotor Stator

  15. 8) Lunar Train

  16. 9) Concept 1) No pipeline 2) LIM system is reasonable for transportation in the moon. - 100km/hr is speed is reasonable - Construction cost is cheaper than LSM. 3) Maglev transportation system with monorail
