AAE 450 Spring 2008 Chris Strauss Aerothermodynamics-Rocket Geometry Scaling Vanguard

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

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

AAE 450 Spring 2008 Regression Equations  Overall Length:  1 st Stage Length: Aerothermodynamics

AAE 450 Spring 2008 Regression Equations  1 st Stage Diameter:  2 nd Stage Length:  2 nd Stage Diameter:  3 rd Stage Length:  3 rd Stage Diameter:
