Abstract
A snow-gun for producing man-made snow from a combination of compressed air and water features a new nozzle configuration for discharging a mixture of water-particles and air into the surrounding atmosphere. Such nozzle is provided with an elliptically-shaped discharge port having a transverse cross-section that gradually expands in size in the direction in which the air and water particles are discharged from said nozzle. Preferably, the area of the elliptical port changes non-linearly through the front wall of the nozzle, whereby water particles exiting the gun through the nozzle port are less likely to collide with the side walls of the port or with each other before reaching the relatively cold ambient atmosphere.
