Airplane Trajectory Results Bradley Ferris Junichi Kanehara Example Orbit Too Aggressive for D&C Conclusions - Good airplane launch trajectories are possible - Airplane launches can be cheaper than balloon launches - Unfortunately D&C cannot control trajectory’s prescribed path AAE 450 Spring 2008 Trajectory Optimization 2/5
Ψ3 Error Sensitivity • Purpose • Find how sensitive the orbit is from an error in Ψ3 • D&C needs this for their controller • Model Used for Analysis • LB-SA-DA-DA • Conclusions • - Perigee is greatly effected by Ψ3 error (1˚ ~= 10% error) • - If there is error, best case is for the error to be more negative • Future Work • - Help the team work on optimizing trajectories for the selected cases. • - Report Writing AAE 450 Spring 2008 Trajectory Optimization 3/5
