Abstract : An aerodynamic sensor has been 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.
