An aircraft that can fly stably when water is discharged from a hose installed on the airframe, and an aircraft system, are provided. The aircraft system can include a master aircraft, slave aircrafts and a remote control device. The aircraft preferably fly as a unit. Each slave aircraft can include four rotary blade portions having propellers, and a suspending means for suspending a part of a hose. The master aircraft may include four first rotary blade portions having first propellers arranged to rotate in a horizontal plane, four second rotary blade portions having second propellers arranged to rotate in a vertical plane, and a nozzle on which a tip end part of the hose is installed. The direction of the center axis of the nozzle is parallel to the direction of the rotational axes of the second propellers.

An aerial retardant delivery system comprising a retardant tank mountable in the fuselage of an aircraft. The tank includes a pressure opening in fluid communication with the fuselage such that pressure in the fuselage may act on retardant contained in the tank. The tank includes an outlet extending through a sidewall of the aircraft's fuselage, through which retardant may be delivered to a target. The system also includes a discharge gate operative to open and close the outlet. An actuation mechanism is disposed on the exterior of the tank and operatively coupled to the at least one discharge gate. A variable flow controller controls the discharge gate open position in order to provide retardant over a desired area of terrain. A one-way flapper is disposed in the pressure opening and is operative to allow pressure in the fuselage to enter the tank while inhibiting retardant from spilling from the tank.

A mobile smoke control and fire protection device for buildings is provided. The device comprises a sealing unit that can be applied to, or inside, an opening of a wall, a ceiling or a floor, is adapted to the opening in terms of the shape and size thereof, and is provided with at least one passage for people and/or at least one passage for tools, firefighting equipment, and the like. The passage for people and/or the passage for equipment can be least partially covered.
摘要:
A system for a firefighting vehicle including a single compressor, driven by the engine of the firefighting vehicle, which generates a compressed fluid supply for operation of both the compressed air foam system and air brakes of the firefighting vehicle. The system can include a fluid storage tank that receives compressed fluid generated by the compressor. The storage tank can be in fluid communication with a dryer and a foaming system. The dryer dries a portion of the compressed fluid and supplies the dry fluid to one or more brake system tanks, which further provide a fluid supply to one or more air brakes of the vehicle to provide a braking force to stop the vehicle. An optionally undried portion of the fluid in the fluid storage tank can be in communication with a conduit which is further in communication with a foam supply and a liquid supply which mix with the compressed fluid to create a compressed fluid foam firefighting material.

A unitary fire pump controller and transfer switch assembly is housed in a single cabinet having a fire resistant barrier dividing the cabinet into at least two separate compartments. A fire pump controller device is contained within a first compartment. An automatic transfer switch is contained in the second compartment and separated from the control device by the barrier.

A firefighting method and apparatus are described for suppressing fires in remote dried out former wetlands/marsh areas. A water pump is positioned upon a floating platform maneuverable in adjacent shallow marsh waters that are not navigable by conventional watercraft. Said pump has an intake port for drawing water from nearby marsh waters and ponds through a hose, said hose having a filtering screen for preventing the pickup of solid materials. The pump has a discharge hose connected to the outflow connection, said discharge hose connected on the distal end to a piping extension projecting away from the hull and over the nearby burning peat lands. Said pump is operated to discharge water over and into the adjacent burning marsh as the platform is maneuvered within the surrounding marsh canals and waterways.

A cartridge monitoring system for use in a cartridge-operated fire suppression system having an enclosure with an opening, sidewalls, an interior space, a cover, and a regulator assembly having a cartridge-receiving opening for receiving a cartridge and a regulator mount. The system includes a fixture positioned in the interior space in a fixed position relative to the regulator assembly; an elongate member having a rotation point fixed to a hinge member, a free end, and an arm portion between the free end and the rotation point, with the elongate member being rotatable about the axis of rotation between a first position in which the free end of the elongate member is within the interior space and a second position in which the free end is outside of the interior space.

A housing unit includes two parts that define a fire-smothering chemical storing interior volume. The housing unit is transported to a target area of a forest fire by an aircraft and dropped onto the target area. An explosive charge is located inside the housing unit and is detonated when the housing unit impacts the ground. The explosion associated with the detonated charge separates the two parts of the housing and disperses the chemical from the open housing unit.
