An air/water snowmaking gun includes a pair of concentric shells (8, 9) defining an annular compressed air chamber (97) and an annular discharge slot (102), and a central water nozzle for spraying an annular stream of water droplets into the center of the stream of air for mixing therewith downstream of the gun. The water nozzle is controlled by a valve (2, 4) which effects volume control, and a turbine (7) is used to effect self-atomizing of the water into droplets. The pattern of the water, i.e. cylindrical or flaring is controlled at the discharge end of the nozzle by a pattern control sleeve (6). The water and air are discharged separately from the gun with their own momentum energy, and only after leaving the gun is there a gradual combination of the two in the plume and entrained ambient air, whereby, temperature permitting, sufficient heat is removed to form snow. |
