Abstract

A method and apparatus to create falling snow for use at ski resorts, theme parks and test and training facilities for use with drones, motor vehicles, autonomous vehicles and aircraft components.

Claims

1. A method of using an apparatus for making falling snow, including the steps of:

viii. lowering a surface temperature of an internal surface of a refrigerated drum of an ice flake generating machine to 0 degrees Fahrenheit (−

20 degrees Celsius) or below, the refrigerated drum connected to a water supply and a refrigeration means to produce ice flakes on the internal surface;

ix. separating the ice flakes produced on the internal surface by utilizing at least one rotating scraper blade that scrapes the ice flakes off of the internal surface;

x. controlling the at least one rotating scraper blade by varying its rotation speed in order to create the ice flakes of various thicknesses;

xi. dropping the ice flakes into a fan impeller, the fan impeller comprising at least an impeller housing and at least one impeller outlet, impacting the ice flakes with turning blades of the fan impeller so that the ice flakes are reduced in size to form snow crystals;

xii. utilizing a cold flow of air which has travelled through the refrigerated drum to reduce air temperature in the impeller housing before the fan impeller blows a stream of the snow crystals out through the at least one impeller outlet;

xiii. adjusting a speed of rotation of the fan impeller to size and control the stream of snow crystals produced; and

xiv. reversing the rotation direction of the fan impeller in order to size, shape, and control the stream of snow crystals produced.

2. The method of claim 1, wherein:

a deflector plate is positioned at the impeller outlet to deflect the stream of the snow crystals as they are thrown at high speed from the fan impeller, controlling size and shape of the stream of snow crystals produced.

3. The method of claim 2, wherein:

the deflector plate moves in a reciprocating motion, deflecting the stream of snow crystals as they are thrown at high speed from the fan impeller, controlling a coverage area of the stream of snow crystals.

4. The method of claim 1, wherein:

the apparatus comprises adjustable legs to maintain a level position.

18. A method of covering large areas with snowfall, using a plurality of the apparatus of claim 1.

19. A snow fall-making apparatus, capable of performing the method according to claim 1.

5. A method for using an apparatus for making falling snow, including the steps of:

ix. combining a plurality of ice flake generating machines together, each ice flake generating machine comprising at least one refrigerated drum, the at least one refrigerated drum connected to a water supply and a refrigeration means to produce ice flakes on an internal surface;

x. lowering a surface temperature of the internal surface of the at least one refrigerated drum to 0 degrees Fahrenheit (−

20 degrees Celsius) or below and producing ice flakes on the internal surface;

xi. separating the ice flakes from the internal surface of each drum by utilizing at least one rotating scraper blade that scrapes ice flakes off of the internal surface of the refrigerated drum,

xii. controlling the at least one rotating scraper blade, varying its rotation speed in order to create the ice flakes of various thicknesses;

xiii. dropping the ice flakes into a screw conveyor to store the ice flakes;

xiv. moving the ice flakes by operation of the screw conveyor to a storage point within the screw conveyor;

xv. connecting an outlet of the screw conveyor to an inlet of a fan impeller in a straight-line configuration, the fan impeller comprising at least an impeller housing and at least one impeller outlet;

xvi. operating the screw conveyor and the fan impeller, making snow crystals of various sizes by forcing the ice flakes from the screw conveyor and/or storage point into the fan impeller and impacting the ice flakes with turning blades of the fan impeller so that the ice flakes are reduced in size to form snow crystals.

6. The method of claim 5, wherein:

a cold flow of air which has travelled through the at least one refrigerated drum is utilized to reduce air temperature in the impeller housing before the fan impeller blows a stream of snow crystals out through the at least one impeller outlet.

7. The method of claim 5, wherein:

a speed of rotation of the fan impeller is adjusted to size and control the stream of snow crystals produced.

8. The method of claim 5, wherein:

a rotation of the fan impeller is reversed in order to size, shape, and control the stream of snow crystals produced.

9. The method of claim 5, wherein:

a speed of the screw conveyor is adjusted to control volume of the snow crystals produced by controlling the intake of the ice flakes into the fan impeller.

10. The method of claim 5, wherein:

a deflector plate is positioned at the impeller outlet to deflect the stream of the snow crystals as they are thrown at high speed from the fan impeller, controlling size and shape of the stream of snow crystals produced.

11. The method of claim 10, wherein:

the deflector plate moves in a reciprocating motion, deflecting the stream of snow crystals as they are thrown at high speed from the fan impeller, controlling coverage area of the stream of snow crystals produced.

12. The method of claim 10, wherein:

a deflector plate can swivel around a circular outlet pipe to create a full 360 degrees of snow fall coverage.

13. The method of claim 5, wherein:

the apparatus comprises adjustable legs to maintain a level position.

14. The method of claim 5, wherein:

the apparatus is controlled by a programmable logic controller (PLC) that can be programmed to replicate different snow fall requirements including light snow fall to blizzard conditions.

15. The method of claim 5, wherein:

the screw conveyor comprises multiple input connectors above and/or beside the screw conveyor to connect to additional ice flake generating machines.

16. The method of claim 5, wherein:

a series of water nozzles are positioned to spray and mix water into the stream of snow crystals produced to form freezing rain, slush or hail.

17. The method of claim 16, wherein:

the apparatus is controlled by a programmable logic controller (PLC) that can be programmed to replicate different snow fall and rain requirements including light drizzle, rain, hail, slush, snow falls and/or blizzard conditions.

20. A snow fall-making apparatus, capable of performing the method according to claim 5.
