1 AAE450 Senior Spacecraft Design Ryan Scott Week 3: February 1st, 2007 Power Group Leader TC, TV, dE, aM, dM, aM, CS1, CS2, CS3

2 AAE450 Senior Spacecraft Design Space Vehicles & Power Need TC (2.8 kW need) –Fuel Cells dE, dM, aM, aE (0.1 kW need) –Batteries *CS1, CS2, CS3 (2.1 kW need) –Solar Power (Battery Backup) Power Need Fuel Cell BatterySolar

3 AAE450 Senior Spacecraft Design Conclusions TC: –3 kW –390 kg –30.5 m 3 total (0.5 fuel cell) *CS1, CS2, CS3: –2.1 kW –49.31 m 2 x 0.1016 ≈ 5 m 2 (2 panels 2.5 m x 9.83 m) –198.96 kg (battery, structure, wires, panels) dE, aM, dM, aE: - 0.1 kW - 106 kg (total) - 0.07 m 3

4 AAE450 Senior Spacecraft Design CS1, CS2, CS3: (fission reactor) - 53.5 kW - 10,844.59 kg - 2.77 m 3 (reactor) SP100 which was developed by the military in the 1980’s Project Legend Scaling
