Stability Derivative Measurements for Magnetically Suspended Cone-Cylinder Models,

Abstract

The present investigation represents an initial application to stability testing of an electromagnetic suspension system which has been operated at the University of Virginia over the past ten years. It follows only a very few stability investigations of somewhat limited scope conducted with magnetically suspended models elsewhere. These tests are aimed primarily at evaluating the practicality of measuring stability derivatives with this apparatus. For the experiments, the nominal objective was to measure the pitching-moment derivative and, particularly, the pitch-damping derivative for each model. After an analytical model for the motion was developed and the data were obtained, it was found that side-force and side-moment-damping derivatives also could be estimated.
