CALIBRATION OF A PRESSURE SENSOR FOR MEASUREMENTS IN CONTINUUM AND RAREFIED GAS FLOWS
MASSACHUSETTS INST OF TECH LEXINGTON LINCOLN LAB
Pagination or Media Count:
The free-stream flow behind shock waves produced in the laboratory has been used to obtain a dynamic calibration of a highly sensitive piezoelectric pressure sensor under a wide variety of conditions. Experimental results on the influence of rarefied gas flow on the value of stagnation pressure measured with the sensor are described. This report covers the continuum, slip and transition flow regimes. Design characteristics of the pressure sensor are presented and experimental results are discussed in view of the impact pressure measurements of other authors.
