Abstract
A system for measuring unsteady pressures in flow fields
employing a remote transducer and thin plastic pressure transmitting
lines has been designed and built. The static and dynamic characteristics of the system were
determined experimentally, and the results were found to agree well
with a theoretical model. The measuring system was subsequently integrated into a twodimensional
wind tunnel model consisting .of a symmetrical airfoil with
a plain oscillating flap. The flap was harmonically oscillated, and
the measuring system was used to determine both the steady and unsteady
pressures at a point near the flap hinge line. The static and dynamic
results were then compared to those obtained using thin airfoil theory
and found to agree well when corrected for thickness effects.
