ABSTRACT:
An angle of attack indicator for use as a cockpit instrument including movable variable-area diaphragms which respond to the differences in pressure at selected points on the aircraft. The pressure points may include the total pressure sensed by the aircraft pitot tube and two other pressures at least one of which varies strongly with the angle of attack. The mechanism divides the difference between total pressure and one of the other two pressures by the difference between the total pressure and the other of the other two pressures obtaining a pressure coefficient which depends only on the shape and angle of attack of the aircraft. The use of the variable diaphragm as the sensitive element of a low level pressure sensor as in an aircraft airspeed indicator is described.
