1. AAE 450 Spring 2008 Allen Guzik January 16, 2008 Trajectory Earth Help Delta V at Different Latitudes and Wind Velocity Consideration Trajectory Optimization

2. AAE 450 Spring 2008 Delta V at Each Latitude  Initial Assessment –Only looks at Velocity gained from the rotation of the Earth –Assume Launched Vertically and directly East Trajectory Optimization

3. AAE 450 Spring 2008 Location and Wind  Average Wind Velocities –4 m/s –5 m/s –7 m/s  Launch Locations –Federal –Commercial (Already Approved) –Proposed Trajectory Optimization Future Work  Earth help Δ v refinement for more accurate representation  Implement into the trajectory code Map Provided From www.googgle.com, Edited by Allen Guzik
