An angle of attack sensor is provided with ports for sensing flow angles in desired planes based upon differential pressure at the ports when a longitudinal or reference axis of the sensor changes relative to the flow stream. Impact pressure is also measured with the same probe, or with a separate probe, and the angle of attack is calculated by subtracting the pressures at the angle sensitive ports, and dividing by the measured impact pressure (qcm). At higher angles of attack, the denominator qcm approaches and passes through zero. When this quantity, q...
An apparatus for determining angles of attack across a substantial range comprising: means for measuring pressures which vary as a function of angle of attack and for providing a first signal that is a function of the difference of such pressures; means for providing a second signal which is a function of a measured pitot pressure and a measured static pressure; means for determining when the second signal is at a selected value different from zero; means for providing a ratio indicative of angles of attack across a first portion of the substantial range...
