Publication number: 20240043120Abstract: A hybrid water storage system for an aircraft includes separate variable volumes for respectively storing/holding potable water and gray water occupying a common container. The hybrid water storage system is generally configured to draw potable water from a first variable volume in order to provide fresh water to one or more aircraft appliances (e.g., sinks, showers, ice-makers, etc.), and the used potable water (i.e., the potable water that is collected in drains from the aircraft appliances), referred to herein as gray water, is routed to a second variable volume that occupies the same container as the first variable volume.Type: ApplicationFiled: October 16, 2023Publication date: February 8, 2024Applicant: GOODRICH CORPORATIONInventors: Kevin Edward Roach, Donald Gregory Roulett, Martin Lei

Patent number: 10889967Abstract: A dual purpose valve assembly may comprise a conduit, a first valve, and a second valve. The first valve may comprise a vacuum breaker valve. The second valve may comprise a check valve. A drain system may comprise a supply tube, a drain tube, and a dual purpose valve disposed between the supply tube and the drain tube. The drain system may allow fluid to drain based on gravity alone, and the dual purpose valve assembly may operate based on gravity alone.Type: GrantFiled: May 15, 2019Date of Patent: January 12, 2021Assignee: Goodrich CorporationInventors: Martin Lei, Kevin Edward Roach, Michael Anthony Ziska

Patent number: 9574928Abstract: A liquid level sensing system includes a vessel and an electrode. The vessel includes a vessel wall separating a vessel interior from a vessel exterior. The electrode is mounted to an exterior side of the vessel wall spanning a distance corresponding to a desired-level-determining range. The vessel wall is a dielectric gap between the electrode and the vessel interior. The electrode is configured to collect a charge corresponding to a liquid level. A method for determining a liquid level in a vessel includes collecting a charge on an electrode, sensing the collected charge on the electrode with a capacitance sensor through an electrical line, and determining a liquid level in a vessel based on the collected charge sensed by the capacitance sensor.Type: GrantFiled: June 27, 2014Date of Patent: February 21, 2017Assignee: Goodrich CorporationInventors: Sabeshan Sean Periyathamby, Jon Shearer, Martin Lei, John A. Harr, Bryan J. Mackulin

Publication number: 20120111432Abstract: An aircraft potable water system (20) comprises outlet facilities (30) and a recirculation path (40) that supplies potable water thereto. The system (20) can operate in a high-usage condition whereat recirculation through path (40) is temporarily interrupted, thereby permitting supply water pressure to remain relatively high despite water being quickly tapped therefrom.Type: ApplicationFiled: October 4, 2011Publication date: May 10, 2012Applicant: Goodrich CorporationInventors: John A.
