Abstract

A floor nozzle for a floor fire suppressant system includes a body and a deflector which is supported on the body. The body includes a transverse passage and a body flange. The transverse passage defines an inlet opening and an outlet opening, with the body flange extending around the outlet opening. The inlet opening is provided for coupling to a fire suppressant supply system. The deflector is spaced from the outlet opening and includes a deflector flange with a plurality of projecting members which extend from the deflector flange toward the body flange. Projecting members are radially spaced around the outlet opening to form a plurality of passageways through which the fire suppressant exiting the outlet opening flows to form a generally lateral radial pattern for delivering fire suppressant to the floor area. The deflector and the body are adapted to support at least a portion of the weight of an aircraft riding over the flange. A floor fire suppressant system for a floor area of an aircraft facility includes a floor grating for positioning over a trench of the floor area, and a nozzle. The nozzle includes a body with a transverse passage defining an inlet opening and an outlet opening, with the inlet opening for communicating with a fire suppressant supply pipe. The nozzle is supported by the floor grating and includes a deflector supported on the body for dispersing fire suppressant exiting from the outlet opening in a generally lateral radial pattern. The deflector is adapted to carry at least a portion of the weight of an aircraft riding over the deflector.
