Publication number: 20230194067Abstract: 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: ApplicationFiled: June 29, 2022Publication date: June 22, 2023Applicant: Goodrich CorporationInventors: ABHILASH KRISHNA, POLY PUTHUR JOHN, SRIJITH PURUSHOTHAMAN

Patent number: 10562351Abstract: A solid-tire-and-hub assembly is provided. The assembly includes a solid tire defining a pair of opposed, spaced side surfaces and a pair of opposed, spaced facial surfaces extending between the side surfaces such that the solid tire defines a substantially trapezoidal transverse cross-section. The solid tire is disposed about a partially hollow hub, which defines a substantially āIā transverse cross-section substantially aligned with the cross-section of the solid tire, an axial aperture configured to receive a drive shaft, and a plurality of holes defined about the aperture. A power-drive unit is also provided. The unit includes a housing, a drive shaft, and at least one of the solid-tire-and-hub assembly connected to the housing.Type: GrantFiled: January 25, 2016Date of Patent: February 18, 2020Assignee: GOODRICH CORPORATIONInventors: Srijith Purushothaman, Kiran Manjunatha, Satya Swaroop Panda
