The practicality of measuring aerodynamic stability derivatives using models suspended in the University of Virginia water-cooled electromagnetic suspension facility is examined. Two non-spinning models are tested in pitch and heave oscillations in a subsonic flow, and both static and dynamic derivatives are determined from the measurements. The two models are 7-caliber and 5-caliber cone cylinders. For the tests, M 0.071 and Red 13,000. Pitch and heave oscillatory motions are induced by forcing the model laterally with its center of mass displaced from its center of magnetization. Each models response is measured in a frequency range near pitch resonance.
