Patent number: 9919173Abstract: A fire suppression system for producing an inert gas mixture having a minimal amount of carbon monoxide, particulates, or smoke. The inert gas mixture may be generated by combusting a gas generant. The gas generant may be a composition that includes hexa(ammine)-cobalt(III)-nitrate. The fire suppression system also includes a heat management system to reduce a temperature of the inert gas mixture. In one embodiment, the system includes multiple gas generators and is configured to ignite the respective gas generant of each gas generator in a predetermined, time based sequential order. For example, the gas generant of each gas generator may be ignited in a sequential order at specified time intervals. Methods of extinguishing fires are also disclosed.Type: GrantFiled: March 11, 2013Date of Patent: March 20, 2018Assignee: Orbital ATK, Inc.Inventors: Reed J. Blau, James D. Rozanski, Richard M. Truitt, Gary K. Lund, William P. Sampson

Patent number: 7845423Abstract: An apparatus, system and method for suppression of fires are provided. In accordance with one embodiment of the invention, a housing is provided with a first opening (or set of openings), a second opening (or set of openings) and a Row path defined between the first and second openings. A fire-suppressing gas is produced, such as from a solid propellant composition, and is introduced into the flow path in such a way that a volume of ambient air is drawn from a location external to the housing, through the first opening and into the flow path. The volume of ambient air may be subjected to an oxygen-reducing process and mixed with the fire-suppressing gas to form a gas mixture. The gas mixture is discharged from the flow path through the second opening and into an associated environment for suppression of a fire located therein.Type: GrantFiled: March 4, 2008Date of Patent: December 7, 2010Assignee: Alliant Techsystems Inc.Inventors: Gary K.

Patent number: 5452210Abstract: A computer-implemented system and method for evaluating gas bag inflator designs are disclosed, including an inflator state machine having slots for signals corresponding to predetermined gas dynamic and heat transfer characteristics of a gas bag inflator at a specified time. Inflator state machines having one or more chambers, and zero or more deflectors, screen packs, burst disks, and vents are supported. Initial temperatures, pressures, and chamber gas contents may be specified, as may the geometry and other characteristics of gas generant pills. A controller in the state machine accesses a chemical database to obtain information about enthalpy, viscosity, and other properties of gas generant combustion products, igniter combustion products, and other compounds present within the gas bag inflator.Type: GrantFiled: January 10, 1994Date of Patent: September 19, 1995Assignee: Thiokol CorporationInventor: James D.

Patent number: 5441303Abstract: A system and method for inflating and deflating an air bag within a vehicle without substantially exposing the occupants of the vehicle to toxic compounds, particulates, and other contaminants in the gas mixture used to inflate the air bag. The system includes a flow guide having an exterior port in fluid communication with the ambient air outside the vehicle, an air bag port connectable in fluid communication with the air bag, and an internal bore permitting fluid flow between the exterior port and the air bag. A nozzle disposed within the flow guide bore is secured to an inflator containing a pressurized gas source. The nozzle and flow guide preferably have certain geometric characteristics disclosed herein. In operation, gas is expelled from the gas bag inflator through the nozzle at a velocity sufficient to entrain ambient air from outside the vehicle. The entrained ambient air mixes with the gas expelled through the nozzle, and the mixture inflates the air bag.Type: GrantFiled: January 10, 1994Date of Patent: August 15, 1995Assignee: Thiokol CorporationInventor: James D.
