The present invention is a force-based instrument that measures local flow angle. The preferred embodiment of the invention has a low aspect ratio airfoil member connected to a mounting base. Using a series of strain gauges located at the connecting portion of the probe, aerodynamic forces on the airfoil member can be converted to strain, which in turn can be converted to local air flow measurements. The present invention has no moving parts and is well suited for measuring flow in a transonic and supersonic regime.
1. A probe for determining airflow direction comprising: a base adapted to be fixed to a moving body; a symmetric airfoil member having a low aspect ratio fin and a neck portion connecting the fin to the base, and a plurality of strain gauges located on the symmetric airfoil member at upper and lower surfaces for the neck portion, the plurality of strain gauges adapted to measure a movement induced force on the fin. 2. The probe of claim 1, wherein the probe comprises no moving parts. 3. The probe of claim 2, wherein the ratio of a chord length of...
