  • Patent number: 5731507
    Abstract: An air data sensing probe adapted for mounting to an aerodynamically-shaped airfoil or strut attached to an air vehicle. An inlet port located near the leading edge of the strut admits fluid, to a first cavity and then, in turn, to a second cavity, so that the total temperature of the fluid may be measured and a signal related thereto conveyed to suitable flight control gear. A first exhaust port located generally opposite the inlet port allows entrained particles to exit the probe and boundary layer fluid evacuation apertures formed through the strut across the interface between the two cavities permit only a substantially particle-free core sample of fluid on the temperature sensing element. The secondary cavity couples to the primary cavity at an angle so that inertial separation of entrained particles results.

  • Patent number: 5628565
    Abstract: An aerodynamic air data sensing probe adapted for mounting to an air vehicle and capable of generating signals related to a fluid flowing relative to the air vehicle. A fluid inlet positioned on a first end of the strut faces generally transverse to the fluid flow selectively admits fluid to an internal strut cavity due to a pressure differential thereacross. In operation, the pressure differential forms between the first end surface of the aerodynamically-shaped, forward-inclined strut and probe exhaust ports. A temperature sensing element disposed in the internal strut cavity registers the temperature of the fluid and the sensed fluid is expelled from the internal strut cavity through the exhaust ports. In another embodiment, a barrel-shaped probe head adapted to sense fluid pressure connects to a portion of the leading edge of the strut to form an aerodynamic multifunction air data sensing probe.
