    摘要： The present invention provides a process for the lay-up of a composite laminate article, the article produced by this process, and the apparatus used to produce the composite laminate article. The composite laminate article may be, for example, an airfoil, particularly useful as a fan blade in a large high bypass ratio turbofan engine, wherein the blade is generally regarded as large and having a high degree of twist. In a preferred embodiment, the present invention provides a process for laying up a composite laminate article comprising a) reading a data set to enable the projection of an image of a ply section onto a work surface, the image indicating a ply section target point; b) laying up a ply section of composite laminating material within the image, wherein the ply section first contacts the work surface at the target point; and c) repeating steps (a)-(b) until the composite laminate article is complete. In a second preferred embodiment, the present invention provides for a lamination apparatus for use in making a composite laminate article comprising a work surface for receiving, in a predetermined sequence, a plurality of ply sections of composite laminating material; a laser projection system using predetermined projection points for outlining an image of a ply section onto the work surface, the image further indicating a ply section target point for making first contact of the ply section with the work surface; and a data set for providing the predetermined projection points to the laser projection system.

    摘要： For the application of humidity-sensitive, aqueous-based paint by spray gun, a compact air shroud assembly adapted to be attached to the spray apparatus about the air cap of the gun to envelope the spray with hot, dry air. The air shroud includes inner and outer annular members to define a passage therebetween. Hot, dry air enters the annular space from the bottom in a direction generally normal to the paint spray pattern and is divided into separate flow paths by a baffle below the inner annular member. From the baffle, the separated air flows pass to various segments of the annular space as directed by vanes in the annular passage. The vanes redirect the flow into a direction parallel with the spray pattern.
