Publication number: 20110105008Abstract: An air purification system for a vehicle may comprise a first heated-ambient-air source comprising an engine with an ambient air compressor; and at least one heated-ambient-air outlet. The system may also comprise a second heated-ambient-air source; a mixing valve; a first heated-ambient-air channel connected between the at least one heated-ambient-air outlet of the engine and the mixing valve; a second heated-ambient-air channel connected between the second heated-ambient-air source and the mixing valve; and a catalytic decontamination unit positioned between the mixing valve and an enclosed passenger cabin of the vehicle for removing contaminants from ambient air and producing decontaminated air to the enclosed passenger cabin.Type: ApplicationFiled: October 30, 2009Publication date: May 5, 2011Applicant: HONEYWELL INTERNATIONAL INC.Inventors: BIJAN F.

Patent number: 6826913Abstract: The present invention is directed to a fluidic system and method for controlling the airflow to a lean premix combustor. The system and method as disclosed allow for reduced power, which results in reduced emissions, while at the same time providing excellent performance. This is accomplished through the use of fluidic means, which do not have the problems associated with hot moving parts of prior art mechanical means. Specifically, the introduction of an airflow downstream from openings in the dilution section cause a local boundary layer separation forcing air into the dilution holes.Type: GrantFiled: October 31, 2002Date of Patent: December 7, 2004Assignee: Honeywell International Inc.Inventor: E. Scott Wright

Patent number: 6513318Abstract: A gas turbine engine includes, in flow series arrangement, a mixer, a compressor, a first flow path of a recuperator, a combustor, a turbine and a second flow path of said recuperator; and a bypass conduit between said turbine and said mixer. A valve is disposed in the conduit and is controlled by a temperature sensor mounted to sense compressor inlet air temperature. The sensor has a set point temperature that corresponds with optimum emissions from the engine. When the sensed temperature drops below the set point temperature the valve opens and hot air from the turbine flows to the mixer where it heats the air entering the compressor. A method for operating a gas turbine engine with preselected emissions over a range of ambient conditions is also disclosed.Type: GrantFiled: November 29, 2000Date of Patent: February 4, 2003Assignee: Hybrid Power Generation Systems LLCInventor: E. Scott Wright

Patent number: 6363706Abstract: A power generating system, including a first shaft, a first compressor, a second compressor and a turbine. In a further embodiment, the system also includes a second turbine, a second shaft and a generator. Each of the first compressor, the second compressor and the turbine are connected to the first shaft whereby the first shaft, the first compressor, the second compressor and the turbine all rotate at the same speed. The first compressor and second compressor are of disparate flow types.Type: GrantFiled: December 17, 1999Date of Patent: April 2, 2002Assignee: AlliedSignalInventors: Kurt Meister, E. Scott Wright

Patent number: 5161365Abstract: A secondary power generating system and method is provided that can drive an aircraft's accessories, and deliver cooling flow and fuel flow to a propulsion engine such as a turbojet, ramjet or turboramjet. This system and method employs a heat exchanger in which high pressure, endothermic, liquid fuel absorbs heat from the air exiting the engine's compressor and as a result is transformed into a high pressure, gaseous fuel. The high pressure gas is expanded across a motor which extracts the pressure energy and converts this energy into mechanical power for driving accessories. The gas is then fed into the engine's combustor where it is ignited. The cooled air exiting the heat exchanger is returned to the propulsion engine and is used for cooling various components such as blades and shafts therein.Type: GrantFiled: December 5, 1990Date of Patent: November 10, 1992Assignee: Allied-Signal Inc.Inventor: E.

Patent number: 5071138Abstract: An annular seal apparatus of the labyrinth type includes at least a pair of axially stacked thin diaphragm members. Each of diaphragm members includes a planar array of radially and circumferentially extending fingers separated by gaps. The pair of diaphragm members are disposed so that the fingers of each block the gaps of the other to define an axially extending annular labyrinth.Type: GrantFiled: May 28, 1991Date of Patent: December 10, 1991Assignee: Allied-Signal Inc.Inventors: Charles G. Mackay, E. Scott Wright

Patent number: 4991394Abstract: A high performance turbine engine includes refrigeration apparatus powered by the engine and effective upon a fractional air flow received from the engine compressor to provide chilled air for cooling of internal engine components. The refrigeration process facilitates rejection of unwanted heat to ambient air despite high stagnation temperatures at high flight speeds. The invention allows increased turbine inlet temperature and improved fuel efficiency or thrust per pound of engine weight with present-day metals and cooling technology being used for engine construction.Type: GrantFiled: April 3, 1989Date of Patent: February 12, 1991Assignee: Allied-Signal Inc.Inventor: E.

Patent number: 4787821Abstract: A rotor member for a turbomachine includes a first portion formed of comparatively higher creep rupture strength material, and a second portion integrally joined to the first portion and formed of comparatively higher tensile strength material. The rotor defines a bore and is configured such that the operative environment thereof inflicts higher temperatures upon the first portion, and higher centrifugally-induced stresses upon the second portion. In order to improve the operating speed, burst margin, or both, of the rotor a plurality of circumferentially spaced and annularly arrayed cavities are provided within the rotor at the union of the two portions. The portions are intimately united by hot isostatic pressing (HIP) so that the rotor is of a single piece (monolithic) having portions of selected physical properties appropriate to the thermal/physical stresses imposed thereon, and defining voids which reduce the weight and bore stresses thereof.Type: GrantFiled: April 10, 1987Date of Patent: November 29, 1988Assignee: Allied Signal Inc.Inventors: Louis D. Cruse, E. Scott Wright
