  • Patent number: 6161769
    Abstract: Method and apparatus for making snow by generating water spray from a triple array of multiple nozzle sub-boom branch-pipes transversely protruding from the upper end of a main boom of a pivotably adjustable snow making pipe tower. Three air jet streams, one for each branch pipe, are simultaneously discharged under high pressure into and sequentially through the throats of each associated multiple stack of water sprays issuing from each set of branch pipe nozzles to thereby form multiple spray plumes of atomized and seeded water all directed forwardly from the upper end of the tower pipe. The water pipe may be an elliptical aluminum extrusion with two interior air tubes respectively controllably feeding large and small diameter air jet arrays to thereby provide a range of air jet water spray interaction.
