Claims
- 1. Snow making apparatus comprising a blower which includes a ducted fan for generating in ambient air which is at or below a temperature of 32.degree. F. a substantially unidirectional high-volume air stream at substantially atmospheric pressure and having linear flow as distinguished from helical or turbulent flow so as to project air stream into a zone overlying an area of the ground on which snow is to be deposited, water spray means including a manifold and a plurality of water spray nozzles disposed in an arcuate array for directing a flow of bulk water in spary form from externally of said air stream into said air stream as said air stream exits said blower from a circumferentially spray zone disposed around less than the entire periphery of said air stream so as to define a gap in the lower portion of said periphery between ends of said arcuate nozzle array, deflector means disposed to impart an upward deflection to a lower portion of said air stream upstream of water flow entry, and means for directing a flow of seed crystals into said air stream through said gap from beneath said air stream and downstream of said deflector means, said flow of water spray and seed crystals being oriented relative to the direction of travel of said air stream such that said flows converge and intermix in said air stream downstream of the respective points of entry of said flows into said air stream.
- 2. The apparatus set forth in claim 1 wherein said means for directing said flow of seed crystals comprises means for mixing a stream of pressurized water and a steam of compressed air and injecting the mixture of pressurized water and compressed air in the form of seed crystals into said lower portion of said air stream.
- 3. The apparatus set forth in claim 1 or 2 wherein said water spray nozzles are oriented for directing said water in spray form into said air stream from a zone disposed generally above said air stream as said air stream exits said blower.
- 4. The apparatus set forth in claim 1 or 2 wherein said deflector means is disposed to deflect said lower portion of said air stream upwardly at an angle of about twenty degrees with respect to the centerline of said air stream.
- 5. The apparatus set forth in claim 4 wherein said deflector means comprises an arcute plate disposed in said blower upstream of said seeder means for asymmetrically deflecting a semi-peripheral portion of said air stream upwardly toward the axis of said air stream and away from said seeder means.
