Abstract

A low profile, rapidly deployable (and redeployable), air pressure sensor for the use in aerodynamic measurement, aerodynamic system optimization and non-invasive validation of aerodynamic theory in motorsport and aerospace was developed and tested for subsonic aerodynamic applications. Three cases – Constant pressure, External flow and Internal flow experiments were considered to validate the performance and accuracy of the sensors. The experiment results demonstrated that this system is accurate, compatible, time saving and non-intrusive for most subsonic aerodynamic applications. The effect of sensor thickness on the flat plate boundary layer was investigated using PIV and the results are presented. New design iteration are proposed to optimize the design.
