Definitions

  • Turbine engine manufacturers continue to seek further improvements to engine performance including improvements to thermal, transfer and propulsive efficiencies.
  • the plurality of fin portion rows includes additional rows including groups of discrete fin portions disposed between the first row and a last row furthest from the inlet.
  • each of the groups of discrete fin portions includes discrete fin portions of a common length and the common length for each of the groups of discrete fin portions increases with an increasing distance from the inlet.
  • the cast part is removed from the mold 106, the cores 102 and 104 are removed using known techniques and the completed heat exchanger is ready for assembly and use.
