Abstract

A free-oscillation test rig has been developed for measuring pitch- or yaw-damping derivatives of sting-mounted models in a trisonic wind tunnel. The rig is limited in applicability to sting-mounted models with moderate fineness ratios and with fairly aft centers of rotation. Results of evaluation testing of the rig with a 25 deg cone model are in good agreement with published data.
