  • Air cycle machine turbine outlet heated diffuser
    Patent number: 8333549
    Abstract: The turbine outlet heated diffuser may include a cavity positioned immediately downstream of an air cycle machine turbine. The turbine outlet heated diffuser may be designed to prevent or reduce ice formation at the turbine outlet by heating the diffuser wall. The cavity may receive a heated flow from an air cycle machine compressor discharge and provide a cavity outlet flow to a turbine inlet plenum. The design of the heated diffuser is such to minimize the cycle performance impact that results from the addition of an air cycle machine icing protection feature.
    Type: Grant

  • Dual-purpose converter/startup circuit for a microturbine power generating system
    Patent number: 6147414
    Abstract: A microturbine power generation system includes an electric generator, a rectifier for rectifying an output of the electric generator, and an inverter for up-chopping an output of the rectifier. The inverter can also be controlled to provide an excitation current to windings of the electric generator. The excitation current causes the electric generator to operate as a motor. The electric generator can be operated as a starter motor for the system.
