Control apparatus
Abstract
Abstract THE METHOD OF AND APPARTUS FOR MEASURING FREE STREAM STATIC PRESSURE OF A FLUID AT BOTH SUBSONIC AND SUPERSONIC SPEEDS, REGARDLESS OF THE SHAPE OF THE VESSEL TO WHICH THE APPARATUS IS ATTACHED, WHEREIN THE STATIC PRESSURE IS MEASURED WITHIN A HOLLOW TUBE THROUGH WHICH THE FLUID PASSES. THE POSITION OF NORMAL SHOCK WITHIN THE TUBE IS CONTROLLED BY VARYING THE SIZE OF NUMBER OF THE OUTLETS IN THE TUBE. THE FREE STREAM STATIC PRESSURE IS THUS DETERMINED BY UTILIZNG KNOWN RELATIONSHIPS BETWEEN THE ACTUAL FREE STREAM STATIC PRESSURE AND THE MEASURED STATIC PRESSURE FOR THAT APPROXIMATE SPEED. THE APPROXIMATE SPEED IS MEASURED BY A SEPARATE SENSOR WHICH MAY BE A PART OF OR SEPARATE FROM THE TUBE.
