Abstract: A metal nitride coated substrate can be made by coating the substrate with an oxide of Al, Ti, or Zr or a hydroxide of Al, Ti, or Zr derived from a sol gel. The coated substrate is heated to a reaction temperature of at least about 850 DEG C and contacted with a gaseous reactant mixture comprising a nitrogen source and a carbon source. The molar ratio of nitrogen to carbon in the gaseous reactant mixture is at least about 15. The coated substrate is maintained at the reaction temperature for a sufficient time to convert the sol gel-derived coating to a metal nitride coating.

Abstract: A turbine airfoil (44) having a baffleless cooling passage (66) for directing cooling fluid toward a trailing edge (72) is disclosed. Various construction details are developed which provide axially oriented, interrupted channels (104) for turning a flow of cooling fluid from a radial direction to an axial direction. In a particular embodiment, a turbine airfoil (44) has a cooling passage (66) including a plurality of radially spaced walls (76), a plurality of radially spaced dividers (82) downstream of the walls (76), and a plurality of radially spaced pedestals (78) positioned axially between the walls (76) and dividers (82). The walls (76) and dividers (82) define channels (104) having an axial interruption permitting cross flow between adjacent channels (104). The cross flow minimizes the adverse affects of a blockage within a subchannel (92) between adjacent walls (76). The pedestals (78) are aligned with the subchannels (92) such that cooling fluid exiting a subchannel (92) impinges upon the pedestal (78).

Abstract: A coolable airfoil (10) having a plurality of spanwisely extending passages is disclosed. Various construction details are developed to increase the cooling effectiveness of the internal structure and decrease the need for cooling air. In one particular embodiment, a leading edge passage (56) has film cooling air flowing over the passage to shelter the passage from the hot working medium gases. This sheltered cooling air is then mixed with heated cooling air from a tortuous passage (84, 92) flowing through the mid-chord region (68) of the blade. In one embodiment, the coating air is supplied to a chordwisely extending tip passage (74) to cool the airfoil tip region and is mixed in the passage (74).

Abstract: A pitch actuation system restraint (PASR) device (10) that provides protection for the pitch actuation system of a helicopter having a main rotor assembly configured for main rotor blade folding operations. The PASR device (10) includes permanent adapter brackets (12) that are permanently mounted in combination with the rotor hub arms (108) and temporary adapter bracket (14) and quick release pins (16) for each main rotor blade to be folded. Prior to implementing blade folding operations, a temporary adapter bracket (14) is secured in combination with the pitch control horn (126) of each main rotor blade and the permanent adapter bracket (12) of the adjacent rotor hub arm (108) by means of the quick release pins (16). Each temporary adapter bracket (14) and permanent adapter bracket (12) functions as a rigid structural interconnection that effectively locks the pitch control horn (126) in position during blade folding operations such that displacements induced in the main rotor blade during blade folding operations cannot be coupled into the pitch actuation system.
