1. AAE 450 Spring 2008 Chris Strauss 1-17-08 Aerothermodynamics-Rocket Geometry Scaling Vanguard

2. AAE 450 Spring 2008 Linear Scaling of Vanguard  Used Vanguard and Purdue Hybrid Rocket dimensions and payload masses to calculate linear regression equations  Results: Aerothermodynamics

3. AAE 450 Spring 2008 Problem Encountered  Linear scaling method does not work well for small payload masses Aerothermodynamics Future Work  Refine scaling functions to work for small payload masses
