3 transportation system for lunar regolith

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


1 design factors

For gaining high value output (He3, etc.) from Lunar regolith

: Mining -> Transportation -> Extraction

1) Design Factors


2 transportation by vehicles

◆ 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.


3 pneumatic transportation

◆ 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


4 pcp pneumatic capsule pipeline

◆ 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.


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


6) Maglev (Magnetic Levitation)

Maglev is using LIM or LSM system for propulsion.

Electric traditional

motor

Linear motor

Attraction

Repulsion



7) Propulsion Systems for Maglev

LIM

LSM

Stator

Rotor

Rotor

Stator



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
