Abstract

An airflow apparatus comprising a stator section, at least one stator blade and a plurality of mounting flanges disposed on the stator section is provided. Additionally, the airflow apparatus includes at least one slot disposed between the plurality of mounting flanges, a rotor assembly coupled to the at least one stator blade, whereby the rotor assembly has a proximal end and a distal end. Furthermore, the airflow apparatus includes at least one fan blade coupled to the rotor assembly. The airflow apparatus also includes a locking apparatus, whereby the locking apparatus includes at least one mounting member and at least one coupling member, wherein the at least one slot is coupled to the at least one coupling member.

Claims

1. An airflow apparatus comprising:

a stator section and at least one stator blade;

a plurality of mounting flanges disposed on said stator section;

at least one slot disposed between said plurality of mounting flanges;

a rotor assembly coupled to said at least one stator blade, said rotor assembly having a proximal end and a distal end; and

at least one fan blade coupled to said rotor assembly;

a locking apparatus, further having at least one mounting member and at least one coupling member, wherein said at least one slot is coupled to said at least one coupling member.

2. The apparatus according to claim 1 wherein said stator section defines an air passage.

3. The apparatus according to claim 1 wherein said at least one mounting member is coupled to a parent apparatus.

4. The apparatus according to claim 3 wherein said at least one mounting member includes an aperture.

5. The apparatus according to claim 4 further comprising a fastening member, wherein said fastening member is coupled to said aperture, said fastening member being further coupled to said parent apparatus, thereby coupling said locking apparatus to said parent apparatus.

6. The apparatus according to claim 1 wherein said plurality of mounting flanges protrude outward along the circumference of said stator section.

7. The apparatus according to claim 1 wherein said plurality of mounting flanges are coupled to said at least one coupling member.

8. The apparatus according to claim 1 wherein said at least one stator blade having a first end and an opposed second end, said first end coupled to said stator section.

9. The apparatus according to claim 8 wherein said opposed second end of said at least one stator blade is coupled to a hub of said rotor assembly.

10. The apparatus according to claim 8 wherein said at least one fan blade is coupled to opposing distal end of said rotor assembly.

11. The apparatus according to claim 1 wherein said airflow apparatus is constructed from a rigid material.

12. An apparatus comprising:

a locking assembly;

at least one mounting member disposed on said locking assembly, wherein said at least one mounting member having at least one aperture;

at least one coupling member disposed on said locking assembly;

an opening disposed within said locking assembly for receiving an airflow apparatus, wherein said airflow apparatus is attached to said apparatus.

13. The apparatus according to claim 12 wherein said at least one mounting member protrudes outward from said locking assembly.

14. The apparatus according to claim 12 wherein said at least one coupling member protrudes inward from said locking assembly.

15. The apparatus according to claim 12 wherein said locking assembly is in the shape of a ring, thereby defining said opening.

16. A method for coupling an airflow apparatus having flanges disposed on a portion thereof to a locking apparatus having at least one coupling member, the method comprising:

aligning at least one coupling member of the locking apparatus to an opening in the flange;

engaging the at least one opening of the airflow apparatus with the at least one coupling member of the locking apparatus; and

rotating the airflow apparatus about the locking apparatus, thereby engaging at least one of the plurality of mounting flanges with the at least one coupling member.

17. The method of claim 16 wherein the locking apparatus is coupled to a parent apparatus.

18. The method of claim 17 wherein the parent apparatus is electronic equipment disposed within one of the following:

aircrafts, ground-based or shipboard apparatuses.

19. The method of claim 18 wherein the electronic equipment is selected from the group consisting of communications equipment, power supplies, avionics and radar.

20. The method of claim 17 wherein the air flow apparatus is constructed from a rigid material.
