Title: Ingestion resistant seal assembly

Abstract

A seal assembly limits gas leakage from a hot gas path to one or more disc cavities in a gas turbine engine. The seal assembly includes a seal apparatus associated with a blade structure including a row of airfoils. The seal apparatus includes an annular inner shroud associated with adjacent stationary components, a wing member, and a first wing flange. The wing member extends axially from the blade structure toward the annular inner shroud. The first wing flange extends radially outwardly from the wing member toward the annular inner shroud. A plurality of regions including one or more recirculation zones are defined between the blade structure and the annular inner shroud that recirculate working gas therein back toward the hot gas path.

  • A seal ring assembly for use in an end face mechanical shaft seal is described comprising: an annular ring casing having a substantially annular end face formed therein with a substantially annular groove; and a seal ring partly received in the groove and secured to the ring casing by an adhesive. The seal ring being formed by segments each having a substantially accurate cross-section, substantially cylindrical radially inner and outer surfaces, axial end faces and side faces. The segments being disposed in the annular groove with one of the end faces of each segment received in the groove and themore » other end face being offset from the end face of the ring casing axially outwardly thereof. The segments being arranged in circumferentially side-by-side abutting relationship with each other to form the seal ring. The other end faces of respective segments being included in substantially the same plane to provide a substantially smooth and circumferentially substantially continuous sealing surface.« less
  • This paper describes a seal and seal shield assembly for a rotary drill bit of the type comprising: a main bit body having at least one leg extending downwardly therefrom the leg having a generally cylindrical journal extending radially inward therefrom comprising a first bearing member of the bit, the journal having end bearing surface on the surface of the leg at the juncture of the journal therewith, a hollow roller cutter with an open end rotatably mounted on each journal, having a bore forming a bearing surface cooperable with the journal, and having a counterbore at the open endmore » thereof defining an annular seal cavity in cooperation with the peripheral surface of the journal and the journal end bearing surface with a peripheral opening therefrom. The annular seal cavity has a fixed end wall comprising the journal end bearing surface, a journal end wall on the roller cutter spaced from the journal end bearing surface and movable relative thereto, a fixed side wall comprising the peripheral surface of the journal, and a side wall on the roller cutter spaced from the journal peripheral surface and movable relative thereto, and means for introducing lubricant into the space between the hollow cutter and the journal.« less
  • This patent describes a nuclear steam generator vessel having a part-spherical bottom wall cooperating with a horizontal tube sheet and a vertical divider plate to define a plenum having a nozzle, apparatus for retaining a nozzle seal in the nozzle against displacement into the plenum comprising: rigid beam means disposed in the plenum, attachment means connecting the beam means to the nozzle seal, anchor means connecting the beam means to the tube sheet, and coupling means bracing the beam means against the divider plate, where the beam means is securely braced between the tube sheet and the divider plate formore » transferring forces coupled to the beam means from the nozzle seal.« less
  • This patent describes a phosphoric acid fuel cell having a fuel cell housing containing a fuel cell stack which is comprised of layered fuel cell plates having edges including adjacent anode and cathode plates having small gaps therebetween for containing an electrolyte solution including seal material which forms a seal between the edges of adjacent anodes and cathode plates wherein the improvement comprises: using a seal material comprising a corrosion resistant, high temperature stable fluorinated hydrocarbon elastomer; a blowing agent which activates within the range of curing temperatures of the fluorinated hydrocarbon elastomer so as to produce a fully curedmore » closed cell elastomer; resulting in improved sealing between structural irregularities in the fuel cell.« less
  • A hydrodynamically lubricated squeeze packing type rotary shaft seal suitable for lubricant retention and environmental exclusion which incorporates one or more resilient protuberances which cooperate with the gland walls to hold the seal straight in its installation groove in unpressurized and low pressure lubricant retention applications thereby preventing skew-induced wear caused by impingement of abrasive contaminants present in the environment, and which also serve as radial bearings to prevent tipping of the seal within its installation gland. 14 figs.
