Patent number: 11123677Abstract: An integrated vortex separator (IVS) is disclosed. The IVS includes a housing in communication with a waste inlet via which a waste stream is drawn under suction into a waste tank. In a first stage, the waste stream is drawn into a centrifugal vortex flow to facilitate the removal of solid and liquid waste from the waste stream, leaving a primary airstream. Within the housing, a filter assembly includes outer and inner inverted cones with a conical cavity therebetween, the cavity serving as a second stage into which the vortex flow is redirected to remove additional liquid from the airstream. Radial vanes extending inward from the outer cone define portals between adjacent vanes, through which the redirected vortex flow is isolated from the original vortex flow. Exhaust ports in communication with the conical cavity allow the substantially moisture-free airstream to be drawn from the IVS via a vent line.Type: GrantFiled: February 20, 2019Date of Patent: September 21, 2021Assignee: B/E Aerospace, Inc.Inventors: Yen Chuh, Thao Hoang, Kristin R.

Patent number: 11001382Abstract: A bypass flow regulator for a vacuum waste system (VWS) is disclosed. The bypass flow regulator includes a valve assembly installable in an aircraft vent line leading outside the aircraft from an onboard VWS waste tank. The vent line directs an airstream pumped from the waste tank to an external outlet under suction (from which outlet the airstream is ejected from the aircraft). The valve assembly includes a group of valves (e.g., umbrella valves) set into the path of the airstream. The valves may collectively modulate the flow rate of the airstream by adjusting their effective flow area.Type: GrantFiled: February 20, 2019Date of Patent: May 11, 2021Assignee: B/E Aerospace, Inc.Inventors: Thao Hoang, Yen Chuh, Kristin R.

Patent number: 10942056Abstract: A system and method for continuous level sensing is disclosed. The system employs a continuous level sensing strain gauge measuring a weight of an aircraft waste tank, a lower and upper point level sensors to signal the system as the liquid level reaches each sensor, and a flush counter to correlate with the CLS and the PLS to determine an average flush volume (AFV). Once the AFV is known and updated, the system determines a weighted waste tank level based on a weighted addition of the flush count and the quantity as measured by the CLS. As the aircraft tank reaches a predetermined value, the system alerts a crewmember to the status.Type: GrantFiled: February 20, 2019Date of Patent: March 9, 2021Assignee: B/E Aerospace, Inc.Inventors: Thao Hoang, Bradley J.

Patent number: 10829918Abstract: A system and related method for touchless control of an aircraft lavatory water supply is disclosed. An aircraft lavatory touchless manifold includes dual solenoid powered water valves opening and closing to regulate water flow through each of a cold conduit and a hot conduit as commanded by user touchless input to a manifold microcontroller commanding the valves. An aircraft input commands a temperature range while a thermal sensor in a mixed water conduit provides output temperature feedback to the manifold microcontroller for positive control of the output temperature. The manifold microcontroller commands opening and closing of the dual solenoid powered valves to create a ratio of opening time between the valves. The solenoid powered valves provide a cost effective and reliable solution offering efficient linear valve operation and effective temperature and flow control.Type: GrantFiled: January 31, 2019Date of Patent: November 10, 2020Assignee: B/E Aerospace, Inc.Inventors: Christina Ortolan, Yen Chuh, Thao Hoang
