  6. Rocket Propulsion

  7. Chemical Rockets • Liquid – typical O2 and H2 • Solid Scientific American – March 2000

  8. Liquid Rockets Scientific American – March 2000

  9. Solid Rockets Scientific American – March 2000

  10. Solid Rockets

  11. Rocket Performance – Mars Mission • Thrust – force 1 N  ¼ lbf • ExhaustSpeed – Measure of fuel efficiency • Sample Burn Time – How long the rocket must fire to accelerate a 25-ton payload from low earth orbit to escape velocity. The time is inversely related to the thrust. • Sample fuel ratio – fraction of the total spacecraft mass taken up by propellant. The amount of fuel is exponentially related to the exhaust speed. Scientific American – March 2000
