ABSTRACT:
A short, strut mounted, multifunction air data sensing probe providing reduced drag, weight and radar cross-section has a modular internal construction providing a multiple passageway pressure assembly to transfer sensed pressure signals from individual sensing ports on a probe barrel to pressure carrying conduits extending into the mounting- strut of the probe. The modular construction eliminates the need for having interior chambers made by fixing a series of difficult to locate bulkheads on the probe, interior, with separate lines running from each of the chambers to provide the pressure signal from each of the ports. The modular construction also permits mounting a deicing heater on internal parts other than the outer probe shell so that the manufacture of-the probe is further simplified, and the types of material used for the probe shell can be changed without concern about heater mounting.
