AAE 450 Spring 2008 Jayme Zott Aerothermodynamics Coefficient of Drag CFD update ref. on all CFD – Brian Budzinski, Chris Strauss

AAE 450 Spring 2008 Overview  Cd varies with AOA and M  Matlab code: –Inputs: Mach, Altitude, AOA –Outputs: Cd (potentially drag) –solve_cd.m  Based on historical and empirical (wind tunnel) data  Note: does not take exhaust plume into consideration Aerothermodynamics Ref. [1] Sutton, Biblarz Ref. [2] Toft Ref [3] Vanguard 2

AAE 450 Spring 2008 CFD Updates  Mesh Completed  Solver running  Continuity residuals are too high Aerothermodynamics Future Work  Correct CFD for Vanguard check  Begin running scaled/new configurations Ref. [4] Budzinski, Strauss 3
