摘要： The cantilevered stator vanes of the compressor section of the gas turbine engine are treated by including a rotating hub having a by-pass passage for removing the low momentum fluid from the main air stream adjacent to the tips of the stator vanes in the compressor and returning it back into the main air stream after having treated the air while avoiding penalties and excessive heating. A plurality of vanes are circumferentially spaced in the by-pass passage for removing vortices and streamlining the flow before injected the air back into the airstream. The vane passage hub treatment is fabricated in a single cast piece in one embodiment, in a three ring configuration in another embodiment and in a segmented ring configuration in still another embodiment.

摘要： An apparatus and method are provided for transferring marine creatures from one pressure environment to another. The apparatus includes a rigid container having at least one access opening, and a fluid-tight closure for the access opening. Structure is provided for gradually permitting the escape of fluid from within the container, and thereby the release of pressure. Pressure-indicating structure is also provided to facilitate the release of pressure within the container at a controlled rate. At least a portion of the container preferably is transparent to permit viewing of the marine animal within the container. A method for transferring marine animals from one pressure environment to another is also disclosed.
