Abstract: The airspeed transducer includes a pair of electrically heated cylindrical sensing elements in a parallel arrangement that is exposed broadside to the incident airstream, simultaneously measuring both instantaneous airspeed and a cross-component of airspeed. The tangent cylindrical elements are joined together with a filler in order to present a flat front face to the airstream, and they are oriented so that the plane defined by their parallel axes is perpendicular to airstream flow. The transducer is electrical with no moving parts and electronic circuitry provides for transducer excitation, operation, and signal readout. A single transducer can be used for measurement of instantaneous airspeed, angle-of-attack, turbulence cross-component, and total turbulence that can also be used in the measurement and computation of T.K.E. or turbulent kinetic energy.
