  1. Chris Strauss2-28-08Aerothermodynamics- CFDDrag Standard Deviation/CMARC Update(Method by Chris Strauss, credit for results and code to Brian Budzinski and Jayme Zott) AAE 450 Spring 2008

  2. Drag Coefficient Standard Deviation • Method • Create a randomizer that produces random values of angle of attack from 0-10 degrees • Fed angles of attack into Cd code to obtain values for Cd • Cd code created by Jayme Zott • Entered values for Cd into Excel to calculate standard deviation with standard deviation function AAE 450 Spring 2008 Aerothermodynamics

  3. Drag Std Dev=13.29% Close to Vanguard drag std. dev. (Drag=10%) Appendix p. A-4, Table A-1. Found that CMARC can only handle flows up to M=0.9 CMARC being dropped as CFD method Results CMARC Update Future Work • Run final design configurations in working Fluent model and write report sections AAE 450 Spring 2008 Aerothermodynamics

  4. References • “The Vanguard Report”, The Martin Company, Engineering Report No. 11022, April 1960 AAE 450 Spring 2008

  5. Backup Slides - CMARC Progress until stopped AAE 450 Spring 2008 Aerothermodynamics

  6. Backup Slides – CMARC Input AAE 450 Spring 2008
