Aerodynamic Stability Testing with Magnetically Suspended Models.
Abstract
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 model's response is measured in a frequency range near pitch resonance.
