Sub-structure • Fusion device • 6” Titanium tubes • Capacitor bank • Hydrogen tank • Pellet factory • Laser • Pusher Plate
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 ²D + ³He → 4-He (3.6 MeV) + p+ (14.7 MeV) 18.3 MeV Total
Fuel Source • 1263.55 kg ²D fuel • 1895.33 kg ³He • Total fuel mass: 3158.88 kg
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 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 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 • Chosen type of fuel D- He3 • 20ps pulses • 100kj energy requirement per pulse • Combined fuel and energy calculations to find 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 • Method of storing energy • Problems with conventional energy storage • Mass • Size • Loss of voltage • Inefficient • Need for plausible source of power for trip
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
Catherine Coleman • Catherine Coleman is a current NASA astronaut • She was a crew member of the expedition 27 to ISS. • While on expedition 27, she spent 159 days in space aboard the international space station.
Sergei Avdeyev • Sergei Avdeyev is a Russian engineer and cosmonaut. • He at one point held record for cumulative time spent in space, with 747.59 days in Earth orbit accumulated through three tours of duty aboard the Mir space station. • The longest time he spent in space was during the Soyuz TM-28 & Soyuz TM-29, in which he stayed 379 days aboard the Mir space station.
Gennady Padalka • Gennady Padalka is a Russian Air Force Officer and an RSA cosmonaut. • Gennady, served as the commander of Mir Expedition 26 launched on August 13, 1998. • He accumulated 198 days and 16 hours of space travel during the Soyuz TM- 28 mission.
