Research extending magnetic balance techniques to produce simultaneous spinning and coning motion of a magnetically-suspended wind tunnel model is reported. Initial measurements of the time varying normal force and side force on a model spinning at 100 rps while coning at 2 Hz are reported for coning angles up to 7 degrees and velocities up to 300 ftsec. Analysis of initial data indicates that improvements in model position sensor stability, balance servo compensation, and data channel filtering will be required to produce data of desired quality.
