Patent number: 8915307Abstract: A nozzle for a fire suppression system has a bonnet and a deflector base. An inlet port extends through the bonnet along the axis of symmetry of the bonnet. The inlet port receives an outlet end of a fire suppression delivery pipe to mount the bonnet to the pipe. The bonnet has a frustoconical surface which extends radially outward and downward from the inlet port. The deflector base is secured to and co-axially aligned with the bonnet at a predetermined distance to create a flow passageway therebetween. The flow passageway imparts a down angle to a suppressant flow discharging from the nozzle to better disperse the suppressant within the fire zone. A discharge port at the circumferential edge of the bonnet and deflector base constricts the suppressant flow to atomize the droplets of liquid suppressant discharged into the fire zone.Type: GrantFiled: December 18, 2008Date of Patent: December 23, 2014Assignee: UTC Fire & Security CorporationInventors: Muhidin Lelic, Giuliano Amantini, May L.

Publication number: 20100212920Abstract: A method and system are provided for suppressing a fire inside a defined volume within a structure. To suppress a fire, the defined volume is flooded with a flow of inert gas into which a limited amount of water is introduced into the flow of inert gas; the flow of inert gas and the limited amount of water introduced therein being sufficient to establish a fire extinguishing atmosphere within the defined volume having a volumetric oxygen concentration of at least about 14%. A cartridge for storing a limited amount of water has a water outlet in flow communication with a spray nozzle that is in flow communication with a supply of pressurized inert gas. The water storage cartridge has a gas inlet in flow communication with a supply of pressurized inert gas for pressurizing the water storage cartridge to cause water to flow therefrom to the spray nozzle.Type: ApplicationFiled: September 24, 2007Publication date: August 26, 2010Applicant: UTC Fire & SecurityInventors: Muhidin A.

Patent number: 7114323Abstract: A system for reducing jet noise emission from an internally mixed gas turbine engine exhaust, comprising a fan/core flow mixer having a plurality of mixer lobes and a common flow nozzle having an equal number of tabs located along a circumferential edge of an aft end of the nozzle. There is a predetermined clocking relationship between the plurality of mixer lobes and the plurality of nozzle tabs that results in reduced exhaust noise emission, most evident in the lower frequency range. A method for reducing jet noise emission from an internally mixed gas turbine engine exhaust comprises selectively aligning a circumferential distribution of a mixed flow vorticity field produced by a fan/core mixer with a circumferentially distributed exhaust flow vorticity field produced by a modified common flow nozzle at an exit plane of the engine exhaust.Type: GrantFiled: March 5, 2004Date of Patent: October 3, 2006Assignee: United Technologies CorporationInventors: Robert Schlinker, Satish Narayanan, Wesley K.
