NAR Level 2 Section D - Rocket Stability Certification Test

A high power rocket's center of pressure can be estimated by:

D: Both "A" and "C" above

The "Barrowman" method is a set of equations developed by J. Barrowman for estimating model rocket stability. More sophisticated methods are available to cover conditions not covered by the Barrowman method, e.g. supersonic flight. Refer to the "Handbook of Model Rocketry" by G. Harry Stine, 6th edition, Chapter 9 on "Stability". Note references on pages 140 and 14, Appendix II, and Appendix IV.
