DEVELOPMENT OF A MINIATURE DYNAMIC PRESSURE GAUGE
Abstract
The report describes the development of a miniature dynamic pressure gage suitable for shocktube use, and for use in shock flows of relatively short duration. Several diskshaped gages, which employed a single sensor of the difference between stagnation and side-on pressure, were fabricated and tested in a shock tube. Each completed gage contained minor modifications of a basic design, and each exhibited a different rise time, noise level, and sensitivity. One of these gages, the Q-5, was delivered to the Air Force Shock Tube Lab in December 1960 and satisfactorily passed evaluation and calibration tests in the 4-in. shock tube, in the 5 to 25 psi region for shock wave durations of 6 to 7 ms. The report describes the operating principles and the design of these gages, and summarizes the development program. It also presents preliminary data on a gage of similar design which incorporates diaphragms in the disk faces, and data on the operating characteristics of the Q-5 gage. (Author)
