Abstract

A system for dispersing liquid over a desired location, the system comprising a pressurized tank having a main body, an inlet in fluid communication with the main body for introducing liquid to the main body, an outlet in fluid communication with the main body for dispersing the liquid, and an air inlet for charging air under pressure into the main body, where the improvement comprises providing a diffuser for slowing down pressurized air entering the main body from the inlet.

Claims (41)

1. A system for dispersing liquid over a desired location, comprising a pressurized storage tank having a main body, an inlet in fluid communication with said main body for introducing liquid to said main body, a first outlet in fluid communication with said main body for dispersing said liquid, a second outlet in fluid communication with said main body for dispersing said liquid, an air inlet for charging air under pressure into said main body, and a diffuser for slowing down pressurized air entering said main body from said air inlet; wherein said storage tank is housed within a fuselage of a host aircraft.

2. The system of claim 1 , wherein said diffuser comprises a base, generally cylindrical side walls, and an opening opposite said base.

3. The system of claim 1 , wherein said storage tank is produced of corrosion-resistant material.

4. The system of claim 1 , wherein said storage tank is produced of stainless steel.

5. The system of claim 1 , further comprising a second outlet from said storage tank.

6. The system of claim 1 , wherein further comprising an additive tank for input of additives.

7. The system of claim 1 , further comprising a discharge pipe in fluid communication with said outlet, wherein said discharge pipe comprises a pintle nozzle, said pintle nozzle being capable of controlling the flow rate of discharge.

8. The system of claim 7 , wherein said discharge pipe comprises an elbow for redirecting a subsequent portion of said pipe generally horizontal to said main body.

9. The system of claim 8 , wherein said elbow is formed at an angle allowing positioning of said pintle horizontal to said main body.

10. The system of claim 8 , wherein said discharge pipe is supported on said storage tank by struts.

11. A system for dispersing liquid over a desired location, comprising a pressurized storage tank having a main body, an inlet in fluid communication with said main body for introducing liquid to said main body, a first outlet in fluid communication with said main body for dispersing said liquid, a second outlet in fluid communication with said main body for dispersing said liquid, an air inlet for charging air under pressure into said main body, and a diffuser for slowing down pressurized air entering said main body from said air inlet; wherein said pressurized tank is mounted on a pallet.

12. The system of claim 11 , wherein said pallet is adapted to reversibly roll-on and roll-off of said host aircraft.

13. The system of claim 11 , further comprising a control interface assembly affixed to an operator chair mounted to said pallet.

14. The system of claim 11 , further comprising a compressor in pneumatic communication with said air inlet and a compressed air storage reservoir between said compressor and said storage tank.

15. The system of claim 11 , further comprising an additive tank for input of additives.

16. The system of claim 11 , wherein the system can be used for fighting fires.

17. The system of claim 11 , wherein the system can be used for dispersing oil, pesticides, bio-remediation materials, defoliant materials, fertilizer materials, or herbicide materials.

18. The system of claim 11 , wherein liquids can be dispensed at over 200 gallons per second.

19. The system of claim 11 , wherein liquids can be dispensed at over 700 gallons per second.

20. The system of claim 11 , further comprising a discharge pipe in fluid communication with said outlet, wherein said discharge pipe comprises a pintle nozzle, said pintle nozzle being capable of controlling the flow rate of discharge.

21. A system for dispersing liquid over a desired location, comprising a pressurized storage tank having a main body, an inlet in fluid communication with said main body for introducing liquid to said main body, a first outlet in fluid communication with said main body for dispersing said liquid, a second outlet in fluid communication with said main body for dispersing said liquid, an air inlet for charging air under pressure into said main body, and a diffuser for slowing down pressurized air entering said main body from said air inlet; and further comprising an additive tank for input of additives.

22. The system of claim 21 , wherein said diffuser comprises a base, generally cylindrical side walls, and an opening opposite said base.

23. The system of claim 21 , further comprising a second outlet from said storage tank.

24. The system of claim 21 , further comprising a compressor in pneumatic communication with said air inlet and a compressed air storage reservoir between said compressor and said storage tank.

25. The system of claim 21 , wherein liquids can be dispensed at over 200 gallons per second.

26. The system of claim 21 , wherein the system can be used for dispersing oil, pesticides, bio-remediation materials, defoliant materials, fertilizer materials, or herbicide materials.

27. The system of claim 21 , further comprising a discharge pipe in fluid communication with said outlet, wherein said discharge pipe comprises a pintle nozzle, said pintle nozzle being capable of controlling the flow rate of discharge.

28. The system of claim 27 , wherein said discharge pipe comprises an elbow for redirecting a subsequent portion of said pipe generally horizontal to said main body.

29. The system of claim 28 , wherein said elbow is formed at an angle allowing positioning of said pintle horizontal to said main body.

30. The system of claim 28 , wherein said discharge pipe is supported on said storage tank by struts.

31. A system for dispersing liquid over a desired location, comprising a pressurized storage tank having a main body, an inlet in fluid communication with said main body for introducing liquid to said main body, a first outlet in fluid communication with said main body for dispersing said liquid, a second outlet in fluid communication with said main body for dispersing said liquid, an air inlet for charging air under pressure into said main body, and a diffuser for slowing down pressurized air entering said main body from said air inlet; wherein liquids can be dispensed at over 200 gallons per second.

32. The system of claim 31 , wherein the system can be used for fighting fires.

33. The system of claim 31 , wherein the system can be used for dispersing oil, pesticides, bio-remediation materials, defoliant materials, fertilizer materials, or herbicide material.

34. The system of claim 31 wherein said diffuser comprises a base, generally cylindrical side walls, and an opening opposite said base.

35. The system of claim 31 , further comprising a second outlet from said storage tank.

36. The system of claim 31 , further comprising an additive tank for input of additives.

37. The system of claim 31 , wherein liquids can be dispensed at over 700 gallons per second.

38. The system of claim 31 , further comprising a discharge pipe in fluid communication with said outlet, wherein said discharge pipe comprises a pintle nozzle, said pintle nozzle being capable of controlling the flow rate of discharge.

39. The system of claim 38 , wherein said discharge pipe comprises an elbow for redirecting a subsequent portion of said pipe generally horizontal to said main body.
