HYDRA 70 MK66 Aerodynamics and Roll Analysis

This report is intended to complement, summarize, and update previous reports on the aerodynamic characteristics of the 2.75 family of rockets. It presents a more detailed basic aerodynamic characterization of the rocket with the two principal warheads that typify most of the configurations of the Hydra 70 system. The reason for publishing this report at this time is that recent studies have suggested application of the MK66 motor, or a derivative thereof, for future systems, and that a more detailed aerodynamic definition in one source may be useful.
