  • Patent number: 10384787
    Abstract: A probe portion of an air data probe is provided. The probe portion includes an endoskeleton structure having an outer surface, a heater cable disposed along the outer surface of the endoskeleton structure, a porous cover, surrounding the endoskeleton structure and heater cable, and a braze filler that substantially fills gaps between the heater cable and the endoskeleton structure and that substantially fills gaps in the porous metal cover.
    Type: Grant

  • Patent number: 7776454
    Abstract: A method for producing titanium alloy brazing strips and the resulting brazing strips and/or foils. The method uses a cold-rolling process without heat treating to generate a titanium based multi-layer alloy strip or foil made up of discrete layers of titanium and an additional layer or layers of one or more metals, such as zirconium, nickel and/or copper, for example, or alloys thereof, with the layer of titanium roll bonded without heat treating to the layers of the additional metal(s). The resulting strip or foil can include, for example, Cu/Ti/Cu, Ni/Ti/Ni, Ni/Ti/Cu, Cu/Ni/Ti/Ni/Cu, Ni/Cu/Ti/Cu/Ni, Ni/Cu/Ni/Ti/Ni/Cu/Ni, Ni/Zr/Cu/Ti/Cu/Zr/Ni and Ni/Ti/Cu/Zr/Cu/Ti/Ni among other combinations. The resulting strip or foil can be used for brazing, creating an alloy of the weight percentage of the original materials.

  • Publication number: 20090288811
    Abstract: A plate fin heat transfer device utilizes titanium plate members and aluminum dividers. The solid bar may be titanium, aluminum or an alloy of either. The titanium plate members may have a thermal conductivity of approximately 50 or 100 BTU/Hr/ft/F/in and dramatically reduce matrix conduction of heat within the plate members. The plate members may be as thin as approximately 0.002 inches while providing the necessary strength to avoid leakage during or after the manufacturing process. The advantageous thinness satisfies weight and volume parameters critical to an aircraft.

  • Patent number: 7527187
    Abstract: The present invention provides a braze foil comprising titanium and zirconium layers covered by one or more layers of copper, nickel or an alloy of copper and nickel such that neither the zirconium or titanium layers are exposed to the atmosphere. The braze foil may further be layered onto a base material during production to form a braze-clad base material. Methods for brazing a base material with the braze foil are also provided.

  • Patent number: 7201973
    Abstract: A heat exchanger of the plate-fin type has fins of one metal brazed to a plate made of a different metal for use in oil coolers, condensers, evaporators, and the like. The distortion-prone titanium fins of conventional heat exchangers may be replaced with another metal, such as a stainless steel or a nickel based alloy to provide a structure that is resistant to crushing at the brazing temperature. Fluid or air flow resistance (pressure drop) through the heat exchanger may also be improved if the selected fin metal forms better fin shapes and has fewer burrs than conventional titanium fins. The replacement material may also improve the heat transfer performance of the heat exchanger if the selected fin metal has higher thermal conductivity than titanium.

  • Publication number: 20040056071
    Abstract: Braze filler in the form of coiled melt spun foil is adhesively bonded to coiled parent sheet metal forming a coiled laminate which can be cut to desired shapes, and brazed as an assembly comprised of laminate and non-laminate parts. Because the parent metal and melt spun foil are cut at the same time, only one piece of material must be handled. The laminate may comprise melt spun foil on one or both sides of the parent metal, may be bonded to the parent metal by means of spraying, rolling, dripping, or brushing, and may be applied to either parent metal or melt spun foil, or both. Application of the adhesive may also be in a pattern rather than covering the entire surface of parent metal.
