摘要

A retardant mixing system is provided to supply retardant mixing solution to a fire-fighting helicopter continuously in the state that the helicopter flies in the air. A retardant mixing system includes a water supply portion, a water tank(260), a mixer(240), a metering pump(230), a main pump(250), a mixing tank, a flowmeter(220) and a control board(290). The mixer is connected to the water tank, receives the retardant, and mixes the retardant with water to form mixed solution. The metering pump is connected to the mixer. The main pump is connected to the water tank. The mixing tank is connected to piping that is formed to make the output sides of the metering pump and the main pump meet each other. The control board controls the water level of the mixing tank.
