Measurements were made at constant height along a single radius on Test Dog and along two different radii for test Easy. In addition, diaphragm-type inductance gages were installed at five different heights on approximately the same radii on test Easy. The spring-piston gage successfully did the job it was designed to do. The diaphragm-type inductance-gage measuring system had an accuracy of 2% in pressure and a resolving time of approximately 1 musec. Complete details concerning equipment design, field operation, and recommendations for future use of the systems are presented.
