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.

An air data sensing probe for determining air data parameters of fluid moving past the probe, and including an elongated probe barrel with a longitudinal axis, said probe barrel having a plurality of port means in the walls thereof for sensing pressures of a fluid relative, to which the probe is moving, a separate assembly internal of the probe for carrying individual pressures from each of the port means comprising a support, axially spaced bulkhead means fixed with respect to the support for-engaging the inner surface of the probe barrel and adapted to be sealingly mounted thereagainst, wall means between the bulkhead means to define at least first and second annularly extending chambers between adjacent bulkhead means, each of said first and second chambers being open to at least one different port, and means on the assembly forming longitudinally extending passageways for carrying fluid pressures open to each of the first and second chambers and extending from a leading end of said barrel toward a trailing end of said barrel.
