Abstract: A system for controlling a flow rate of a compressed cooling medium between a compressor section and a turbine section of a gas turbine includes a flow path that is defined between the compressor section and the turbine section of the gas turbine and a thermally actuated variable flow valve disposed within the flow path. The variable flow valve defines an opening that changes in size based on a temperature of the compressed cooling medium flowing therethrough.

Abstract: In a turbomachine having an inlet, a compressor, and a turbine, a closed loop sends fluid from a stage of the compressor to a heat exchanger in the turbine and to the inlet. The closed loop heats the fluid, cools the turbine, and delivers heated fluid to the inlet. A mixer can be interposed between the heat exchanger and the inlet to mix fluid from the heat exchanger with compressor discharge fluid, delivering the mixed fluid to the inlet. The mixer can control flow received so that desired temperature and/or flow rate can be provided to the inlet.

Abstract: An inlet air filtration unit for a gas turbine includes an inlet filter house having an upstream surface through which air is ingested. A plurality of weather hoods is secured to the upstream surface. A wave-generating system is installed on or proximate to the plurality of weather hoods, the wave-generating system emitting waves that deter pests from the inlet filter house. A method of deterring pests from entering an inlet filter house of an inlet air filtration system is also provided. The method includes: installing a wave-generating system proximate to or on a weather hood on an upstream surface of the inlet filter house; and energizing the wave-generating system to produce energy waves across the upstream surface of the inlet filter house.

Abstract: A cooling arrangement for a gas turbine engine. The cooling arrangement comprises a discharge channel for air flow from a compressor, a first cooling channel and at least one aperture providing communication between the flow of air through the discharge channel and the first cooling channel. A restrictor device in the aperture regulates the flow of air between the discharge channel and the first cooling channel. The restrictor device deforms to vary air flowing through the aperture in response to a physical condition of the engine. This physical condition of the engine may be that of the temperature of air flowing through the discharge channel, the restrictor device responding to regulate the flow of air based on that temperature. The restrictor device may be a two-way shape memory alloy.
