Abstract: Fire extinguishing, suppression and control systems, nozzles, nozzle assemblies, and methods for delivering fire extinguishing agents from locations outside the interior of an enclosure and then delivering such agents to the enclosure interior. A fire extinguishing agent is introduced into an interior nozzle body cavity of a nozzle body so that the agent flows though the interior nozzle body cavity in an axial direction thereof. The agent is discharged through orifices located in a wall of the nozzle body so that the agent continues to flow in the axial direction into a tube cavity that extends along an axis that is coaxial with the axial direction of the nozzle body so that the agent continues to flow in the axial direction. The agent exits the tube cavity through an outlet that is coaxial with the axial direction so that the agent exits the tube in the axial direction.

Abstract: A locomotive is described including a frame having a wall with a roof and floor defining an enclosed space thereon. A turbine engine is disposed within the enclosed space. An air inlet is provided to permit ingress of air into the enclosed space for ingestion by the turbine and for circulation around the turbine to cool the turbine. A first silencer is disposed between the air inlet and the turbine to minimize noise generated by the turbine. An exhaust duct, for connection to the exhaust outlet of the turbine, is also provided to permit egress of exhaust gases generated by the turbine from the enclosed space. In addition, a second silencer, connected to the exhaust duct, is provided to minimize noise generated by the turbine. Finally, at least one of the wall, roof, and floor of the enclosed space incorporate noise dampening materials to minimize noise generated by the turbine. An enclosure assembly for a turbine is also disclosed.
