Abstract
A heating system for a ram air turbine includes a heated screen that is disposed across an air inlet defined by a strut. The strut has a first end that is connected to a generator that is operably connected to a turbine that is connected to a second end of the strut. The heated screen has a heating element embedded therein.
Claims11
A ram air turbine system, comprising:
- a strut that is pivotally connected to a mounting frame that is operatively connected to an aircraft structure, the strut defining a strut body that extends between a first end and a second end, the strut body defining an air inlet;
- a frame disposed about the aft inlet and extends above an exterior surface of the strut body;
- a heated screen connected to the frame and disposed over the air inlet, the heated screen having a heating element embedded within the heated screen, the heating element being a film applied to the heated screen;
- a turbine that is disposed at the second end of the strut;
- and
- a generator that is disposed proximate the first end of the strut, the generator being drivably connected to the turbine via a drive shaft.
3 more elements
A ram aft turbine system, comprising:
- a strut having a first end that is connected to a generator that is drivably connected to a turbine connected to a second end, the strut provided with an air inlet that is disposed proximate the first end;
- a frame disposed about the air in and extends above an exterior surface of the strut;
- a heating system being electrically connected to the generator, the heating system having a heated screen disposed over the air inlet and connected to the frame, the heated screen including a heating element disposed between a first screen and a second screen element that is spaced apart from and disposed opposite the first screen element, the heating element comprising a film applied to at least one of the first screen element and the second screen element.
