Abstract
A drain grommet with integrated fire shield. In one embodiment, the drain grommet includes a drain tube configured to extend through a drain, and to pass fluid through the drain via an opening into a hollow channel of the drain tube. The drain grommet further includes a fire shield integrally coupled with the drain tube via a standoff, wherein the standoff supports the fire shield at a vertical distance above the opening of the drain tube, and wherein the fire shield is larger than the opening of the drain tube in a horizontal plane.
Claims20
An apparatus comprising:
- a drain tube configured to extend through a drain, and to pass fluid through the drain via an opening into a hollow channel of the drain tube;
- and
- a fire shield integrally coupled with the drain tube via a standoff, wherein the standoff supports the fire shield at a vertical distance above the opening of the drain tube, and wherein the fire shield is larger than the opening of the drain tube in a horizontal plane.
A drain grommet for a drain in a cavity of an aircraft, the drain grommet comprising:
- a drain tube to fit in the drain, the drain tube including a hollow channel to convey fluid through the drain;
- a flange at one end of the drain tube to support the drain grommet in the cavity, the flange including an opening into the hollow channel of the drain tube;
- a standoff protruding perpendicularly from a top surface of the flange;
- and
- a fire shield coupled to the standoff at a distance above the opening of the flange.
A wing cavity of an aircraft, the wing cavity comprising:
- one or more cables of the aircraft;
- a drainage hole in a floor of the wing cavity;
- a drain grommet for the drainage hole, the drain grommet including:
- a tube to fit inside the drainage hole;
- a flange around the tube to support the drain grommet on the floor of the wing cavity;
- an opening in the flange and the tube to drain fluid from the wing cavity;
- a standoff protruding vertically from the flange;
- a fire shield mounted on the standoff vertically above the flange;
- wherein the fire shield is disposed between the opening of the drain grommet and the one or more cables of the aircraft.
