Abstract:

The DSTO water tunnels balance and rotary support mechanism provides a measurement capability for longitudinal dynamic derivatives. This report documents the underlying theory and computational implementation of a technique which uses the water tunnel for determination of normal force and pitching moment coe cient derivatives with respect to angle of attack, non-dimensional pitch rate and angle of attack rate.
