Structure

Structure

Living quarters modeled after the Mir living module

Standard life support

Exercise equipment

Solar panels

Experimental equipment

Docking Port

Food, Water

Waste Facility


Sub structure

Sub-structure

  • Fusion device

  • 6” Titanium tubes

  • Capacitor bank

  • Hydrogen tank

  • Pellet factory

Safety

Safety

Radiation large concern

Duration of human space mission is 90 days

Secondary radiation

Galactic cosmic radiation

Solar energetic particles

Interact with space structures

Generally ignored in space architecture

Neutrons emitted from fusion reaction

Use Deuterium-Helium3

Prolonged exposure includes radiogenic cancers

  • Boron nitride nanotubes

  • Low atomic number atoms

  • Can be processed and hydrogenated


Fuel source

Fuel Source

²D + ³He → 4-He (3.6 MeV) + p+ (14.7 MeV)

18.3 MeV Total


Fuel source1

Fuel Source

  • 1263.55 kg ²D fuel

  • 1895.33 kg ³He

  • Total fuel mass: 3158.88 kg

Fast ignition

Fast Ignition


Fast ignition1

Fast Ignition

Magnetic Confinement Fusion

Magnetic confinement is impractical

Torus (Tokamak) - “Their great size and mass render them unappealing for space propulsion, where lightweight is paramount."

Primary Problem – Difficult to sustain the fusion reaction while ‘leaking’ out plasma

Mirror - “The dearth of experimental data on their operation and indeed their engineering feasibility render serious engineering assessment difficult"

Torus

Mirror


Fast ignition2

Fast Ignition

Inertial Confinement Fusion

Avoids magnetic confinement’s main problem

Existing plasma not required

Constant flow of fuel pellets makes new reactions

Complex magnetic fields not needed

Simple Pusher Plate

Directs charged ions backwards


Fast ignition3

Fast Ignition

Specifics:

Tradition ICF’s still have problems

National Ignition Facility reactor contains 192 lasers delivering a total of 500 terawatts of power

Fast Ignition

Concentrates laser energy on single point

Reduces amount of lasers, energy required, and design complexity


Fuel and energy

Fuel and Energy

  • Chosen type of fuel D- He3

  • 20ps pulses

  • 100kj energy requirement per pulse

  • Combined fuel and energy calculations to find totals


Mission totals

Mission Totals

  • Burn time of 6 hours to reduce G load

  • Laser firing every 20ps

  • 5.00 x 10^15 watts

  • 1.08 x 10^20 Joules

  • Power of NIF is 1.25x10^15 watts


Energy source

Energy Source

  • Method of storing energy

  • Problems with conventional energy storage

    • Mass

    • Size

    • Loss of voltage

    • Inefficient

  • Need for plausible source of power for trip


Graphene

Graphene

  • High capacity energy storage device

  • Energy density 10-20 times greater than conventional

  • Thin layers create huge surface areas to store energy on.

  • Create a “black box” to store the initial power required
