  1. Elizabeth HarknessTrajectory Design Group ContactPreliminary Trajectory Model:Vertical Launch AAE 450 Spring 2008

  2. Comparison of Launch System Performance Comparison of altitudes using vertical launch trajectory. -Plot generated by: Elizabeth Harkness -From code generated by: Junichi Kanehara and Amanda Briden -with assistance from: Elizabeth Harkness AAE 450 Spring 2008 Trajectory Optimization

  3. Comparison of Launch System Performance 1. Initial conditions for Balloon and Aircraft Launches found in cited articles. AAE 450 Spring 2008 Trajectory Optimization

  4. Model Assumptions • Values input into code are from Vanguard data Table 20. Payload of 100 lbs, orbit at 180 statute miles. • All stages are modelled vertically. • Poor assumption • Does not take into account the lengthy portion of trajectory through the atmosphere. • Preliminary test of trajectory code and comparison of three of the launch methods AAE 450 Spring 2008
