An Omindirectional Pressure Gage for Measurement of Weak Blast Waves

摘要

An aerodynamic sensor was developed which is applicable to the measurement of the static pressure behind weak blast waves. The sensor is a ventilated sphere suitable for use with various types of electronic sensing units. A method used for prediction of response characteristics, ventilation coefficients, and sizing parameters gave good preliminary results in the range of 3 to 10 psi overpressures. Preliminary test results indicate a considerable increase in omnidirectional capability over previous gage types for this application. The preliminary program was limited to design of an experimental configuration and evaluation of concept feasibility. (Author)
