Dynamic Testing with the NSWC Three-Degree-of-Freedom Gas Bearing

摘要

This report presents the design, construction and operational procedures of the NSWC Three-Degree-of-Freedom Gas Bearing. The data reduction technique that is used with angular measurements from this support is developed and applied to measured wind tunnel data. These wind tunnel data were obtained from non-ablating and ablating models undergoing dynamic motion in the NSWC Hypersonic Wind Tunnel. Test results are compared with earlier experiments with dynamic ablating models and theoretical speculations.
