Patent number: 12270523Abstract: An aircraft exterior light unit may comprise a magnetically controlled fluid drain valve configured to expel liquid water from the light unit. The valve may include a permanent magnet configured to induce a magnetic flux circuit that generates a magnetic force configured to close the valve. The valve may be configured to open when the pressure inside the light unit exceeds the magnetic force. As the valve opens and expels the water, the pressure within the light unit may decrease, equalizing with that of the external environment. As the magnetic force generated by the magnet increases as the valve is open and the water expelled, the magnet may be configured to close the valve once more. As such, the magnet may be configured to control a self-acting fluid drain valve in an aircraft exterior light.Type: GrantFiled: June 29, 2022Date of Patent: April 8, 2025Assignee: GOODRICH CORPORATIONInventors: Abhilash Krishna, Poly Puthur John, Srijith Purushothaman

Publication number: 20240183515Abstract: A system is provided for illuminating a winglet cap of a winglet. The system includes the winglet cap, a light source, a total internal reflection (TIR) lens positioned in proximity to the light source, and a prismatic lens positioned between the light source and the winglet cap. In the system, light produced by the light source reflects off a surface of the TIR lens and passes through the prismatic lens. In the system, the prismatic lens bends the light and directs the bent light toward an inside surface of the winglet cap.Type: ApplicationFiled: February 24, 2023Publication date: June 6, 2024Applicant: GOODRICH CORPORATIONInventors: Yaswanth Kumar Maddali, Abhilash Krishna
