CONTINUOUS RECORDING OF PRESSURES FOR SUPERSONIC WIND-TUNNEL CALIBRATION
Abstract
Equipment was designed for automatic use of an electronic potentiometer recorder for pitot and static pressure distributions in the test section of a supersonic wind tunnel. A probe support was designed to be driven at a constant speed parallel to the air stream. A static or pitot probe was used together with an electrical transducer. The equipment also included manometers, a reference-pressure tank, and a multiple valve. Records for the flow in an M = 2.48 nozzle showed a greater spatial resolution for a pitot probe compared to that of a static probe with about the same diameter. The use of the former for measurements of local or scale conditions was suggested. The appendix describes a method for accurately determining the stagnation pressure from pitot pressure records.
