  • Publication number: 20180257788
    Abstract: An aircraft system includes an aircraft fuselage, an auxiliary power unit and an air inlet assembly. The auxiliary power unit is within the aircraft fuselage. The auxiliary power unit may be configured as or otherwise include an engine. The air inlet assembly includes an inlet orifice, an inlet duct and a door. The inlet duct fluidly couples the inlet orifice with an airflow inlet of the engine. The door is configured to pivot about a generally horizontal pivot axis between an open position and a closed position. The door opens the inlet orifice in the open position and substantially closes the inlet orifice in the closed position.

  • Patent number: 10060284
    Abstract: A total air temperature (TAT) sensor assembly is disclosed. The assembly includes a housing that accommodates a temperature sensor. The assembly also includes a first airfoil that includes a leading end and a trailing end and a second airfoil that includes a leading end and a trailing end. The first and second airfoils are disposed in a spaced-apart fashion that defines a curved passageway so incoming air can flow between the first and second airfoils before engaging the housing and the temperature sensor. The trailing ends of the airfoils are disposed on opposite sides of the housing and spaced apart from the housing to permit air flowing through the curved passageway to pass the housing.
