摘要： An exhaust muffler is provided for a turbine engine with at least first and second exhaust outlets. The exhaust muffler includes a first arm configured to be coupled to the first exhaust outlet of the turbine engine. The first arm includes an outer surface, and an inner surface that defines a first exhaust cavity. The first arm further includes a plurality of perforations extending between the inner and outer surfaces. The exhaust muffler further includes a second arm coupled to the first arm and configured to be coupled to the second exhaust outlet of the turbine engine. The second arm includes an outer surface, and an inner surface that defines a second exhaust cavity. The second arm also includes a plurality of perforations extending between the inner and outer surfaces.

摘要： A swirl generator for creating bulk swirl in a compressor plenum in the opposite direction to the direction of rotation of the compressor rotor. The generator includes a continuous flow passageway formed by an inlet duct and a compressor forming an angle in the range of about 0°-180° to one another. A non-uniform velocity gradient is created by forming an area of non-uniform cross-sectional area within the flow passageway. The non-uniform area may comprise a ramp with a tapered end line, a rounded line of intersection, a fillet or by lengthening one side wall of the inlet duct relative to the opposite side wall. Preferably, the non-uniform cross sectional area uniformly tapers from ones sidewall of the flow passageway to the opposite sidewall.
