Patent number: 10946969Abstract: A ventilation system, aircraft, and method. The ventilation system includes a first conduit in fluid communication with a first air source in the aircraft to direct a fluid flow from the first air source. The ventilation system also includes a first branch in fluid communication with the first conduit and a first outflow point, the first branch including an active air mover to move the fluid flow toward the first outflow point. The ventilation system further includes a second branch that is separate from the first branch and in fluid communication with the first conduit and a second outflow point, the second branch including a passive air mover to move the fluid flow to toward the second outflow point.Type: GrantFiled: August 12, 2014Date of Patent: March 16, 2021Assignee: THE BOEING COMPANYInventors: Casey Y.

Patent number: 7849931Abstract: An integrated environmental control system for a cargo stowage compartment in a mobile platform, for example in a commercial passenger jet aircraft. A fire detection/suppression subsystem is integrated together with an airflow management system. The airflow management system operates to circulate, and optionally to heat or cool, air withdrawn from a cargo stowage compartment of the aircraft before the air is released back into the cargo stowage compartment. A fire suppression substance, for example, Halon gas, can be discharged directly into a recirculation duct of the airflow management system, thus reducing the duct work required to achieve fire suppression and ventilation operations for the cargo stowage compartment. The integration of the fire detection/suppression and airflow management system operations reduces the overall amount, complexity and weight of the ducting employed in a cargo stowage compartment of a commercial jet aircraft.Type: GrantFiled: September 7, 2006Date of Patent: December 14, 2010Assignee: The Boeing CompanyInventor: Casey Y.

Patent number: 7687927Abstract: An electrical architecture for an aircraft is provided. The electrical architecture is particularly suitable for relatively small, compact, and lightweight aircraft. In one embodiment, the electrical architecture includes an electrical generator component coupled to the aircraft engine, and an air compression system coupled to the electrical generator component. The electrical generator component is configured to receive mechanical power from the engine and to generate a constant frequency AC electrical power from the engine mechanical power, and the air compression system is configured to receive the constant frequency AC power as an input and, in response thereto, produce a pressurized air output having variable characteristics (for example, a variable flow rate or a variable air pressure).Type: GrantFiled: November 21, 2007Date of Patent: March 30, 2010Assignee: The Boeing CompanyInventors: Mark S. Shander, Richard A. Cote, Michael L. Drake, Howard Carter, III, John T. Peters, Casey Y. K. Ng, Michael S. Hoag, John T. Paterson

Patent number: 7210653Abstract: Methods and systems for providing secondary power to aircraft systems. In one embodiment, an aircraft system architecture for providing power to an environmental control system includes an electric generator operably coupled to a jet engine. The jet engine can be configured to provide propulsive thrust to the aircraft, and the electric generator can be configured to receive shaft power from the jet engine. The environmental control system can be configured to provide outside air to a passenger cabin of the aircraft in the absence of bleed air from the jet engine.Type: GrantFiled: October 21, 2003Date of Patent: May 1, 2007Assignee: The Boeing CompanyInventors: Warren A. Atkey, Alan T. Bernier, Michael D. Bowman, Thomas A. Campbell, Jonathan M. Cruse, Charles J. Fiterman, Charles S. Meis, Casey Y. K. Ng, Farhad Nozari, Edward Zielinski

Patent number: 6449963Abstract: An air conditioning system and method are provided for use in an aircraft having a pressurized area and an unpressurized area. The air conditioning system includes an air conditioning pack located in the unpressurized area of the aircraft that conditions fresh air. The air conditioning system also includes a first air duct for directing a flow of recirculation air from the pressurized area, through a pressure bulkhead, and into the unpressurized area. A mixer is also provided and advantageously positioned in the unpressurized area for mixing the conditioned air from the air conditioning pack and the recirculation air from the pressurized area. Advantageously, the mixer obviates the need for a mix manifold and saves valuable space for passengers, cargo, and other aircraft equipment. The air conditioning system also includes a second air duct that directs the mixture of conditioned air and recirculation air from the mixer to the pressurized area of the aircraft.Type: GrantFiled: December 19, 2001Date of Patent: September 17, 2002Assignee: The Boeing CompanyInventors: Casey Y.
