  • Flow splitter for gas turbine engine
    Patent number: 8833087
    Abstract: A splitter is disclosed that can be coupled with a splitter support and used within a diffuser of a gas turbine engine. The splitter includes apertures for receiving a portion of the splitter support. The splitter support includes support arms that are adapted to be slidingly received within the apertures of the splitter.
    Type: Grant

  • Method for designing a cyclic symmetric structure
    Patent number: 6542859
    Abstract: A method for analyzing and designing structures with structural aliasing. The concept of structural aliasing applies in one embodiment of the present invention to structural systems which are cyclically symmetric. In analyzing and designing structural systems such as wheel assemblies of gas turbine engines, it is possible to group the discrete components so as to aliasingly couple particular ordered excitations and harmonic families. With structural aliasing, it is possible to couple the ordered excitations and harmonic families such that resonant response of the wheel assembly does not occur within the operating range of the engine, and also to have the resonant vibratory mode excited in such a manner that the drive coupling of the wheel dampens the wheel assembly.
