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.

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.
Abstract translation: 公开了一种总空气温度（TAT）传感器组件。 组件包括容纳温度传感器的壳体。 组件还包括包括前端和后端的第一翼型件和包括前端和后端的第二翼型件。 第一和第二翼型件以间隔开的方式设置，其限定弯曲的通道，使得在接合外壳和温度传感器之前，进入的空气可以在第一和第二翼型之间流动。 翼型件的后端设置在壳体的相对侧并且与壳体间隔开，以允许空气流过弯曲通道以使壳体通过。
