Abstract:
Wind-off, bench tests on a wind tunnel model that had freedom to pitch, and yaw, but no freedom to roll indicated that the pitching and yawing motions were inertially coupled. An order of magnitude analysis showed that this coupling was due to the product of inertia term I sub YZ. The inertially coupled equations of motion are solved, and a method is presented for determining the magnitude and sign of L sub yz from recordings of the model motion. The method used to dynamically balance the model is described, and experimental results are presented that verify this method.
