 | A propane-fueled combustor was built to support the development of an alternate to the external fire test currently required for final Hazards Classification (HC). The device has the capability to provide a controlled heat flux environment of 40-400 kW/sq m (12,600- 126,000 Btu/hr/sq ft). This results in a repeatable and quantifiable environment for the evaluation of the fast cook-off response of an ordnance item. |

| Acoustic stabilization of combustion in a dump configuration results in completion of combustion in a relatively short residence time with simultaneously low emissions of oxides of nitrogen, carbon monoxide, and hydrocarbons. Acoustically stabilized combustion is also a potential means for achieving closed-loop active control of combustion. Therefore, a promising burner configuration identified through laboratory bench-top experiments was developed and scaled up for application as an afterburner for a starved-air incinerator ... |

|
 | An improved method and apparatus for actively controlling a combustion process such as a waste incinerator by means of a spatial and temporal synchronized injection of fuel. The improved method and apparatus employs an active control system which controls the intentional formation of large scale, coherent vortices and the synchronized injection of the fuel supply at various locations relative to the formation of the vortices. The preferred apparatus composes an ... |

|
| The oscillations found to occur in the cavities of an structural frame moving through a fluid are substantially eliminated by the adoption of perturbation elements located at the leading edge of the cavity and reflecting any remaining oscillations out of the cavity at the trailing edge. The perturbation elements may take the form of multiple pins of various shape and geometrical arrangement which prevents the generation and growth of vortices ... |

|
| A regenerative liquid propellant gun and pertains includes a modified conventional fixed bolt extending into a conventional combustion chamber of the regenerative liquid propellant gun. The modified fixed bolt of this invention provides for improved operation of the otherwise conventional regenerative liquid propellant gun and has modified end portion embodiments and internal propellant injection passages, all for the purpose of creating turbulent propellant flow. |

|
| The patent is directed to a fluid mixing device in which a jet of first fluid is passed through a nozzle having a conical inlet section and a noncircular, elongated, exit section. The jet of first fluid mixes with a second fluid located downstream of the device. In operation, the intersection of the conical and elongated sections produces axial rotation in the first fluid. Intense, three-dimensional, axial and circumferential vortical ... |
