Abstract

A fuze mounting assembly for a penetrating, the fuze mounting assembly includes a fuze well and a fuze. The fuze includes an integral flange for securing to the fuze well.

Claims (38)

1. A fuze mounting assembly of a penetrating weapon comprising:

a fuze well having a receiving well formed therein; and

a fuze including a fuze housing having an integral flange formed thereon, a portion of the fuze housing being received in the fuze well and the integral flange being secured to the fuze well, the fuze mounting assembly configured to exhibit an amplification of acceleration of less than 3.0 when subjected to impact and penetration shock responsive to the penetrating weapon contacting a target.

2. The fuze mounting assembly of claim 1 , wherein the amplification of acceleration of less than 3.0 comprises an amplification of acceleration of less than 2.6.

3. The fuze mounting assembly of claim 1 , wherein the amplification of acceleration of less than 3.0 comprises an amplification of acceleration of less than 2.2.

4. The fuze mounting assembly of claim 1 , wherein the fuze mounting assembly is further configured to exhibit an amplification of deceleration of less than −2.7.

5. The fuze mounting assembly of claim 4 , wherein the amplification of deceleration of less than −2.7 comprises an amplification of deceleration of less than −3.2 and the amplification of acceleration of less than 3.0 comprises an amplification of acceleration of less than 2.6.

6. The fuze mounting assembly of claim 4 , wherein the amplification of deceleration of less than −2.7 comprises an amplification of deceleration of less than −2.3 and the amplification of acceleration of less than 3.0 comprises an amplification of acceleration of less than 2.2.

7. The fuze mounting assembly of claim 1 , further comprising a plurality of circumferentially spaced fasteners securing the integral flange to the fuze well.

8. The fuze mounting assembly of claim 7 , wherein at least one fastener of the plurality of circumferentially spaced fasteners comprises a nut and stud combination.

9. The fuze mounting assembly of claim 7 , wherein at least one fastener of the plurality of circumferentially spaced fasteners comprises a bolt.

10. The fuze mounting assembly of claim 1 , wherein the fuze well includes a plurality of threaded holes therein and wherein the integral flange is secured to the fuze well by a plurality of circumferentially spaced fasteners extending at least partially through the plurality of threaded holes.

11. The fuze mounting assembly of claim 1 , wherein the fuze housing includes at least one of an exploding foil initiator, fuze electronics, a fuze acceleration sensor, and a lead charge.

12. The fuze mounting assembly of claim 1 , wherein the fuze housing includes a cylindrical housing having an aft end and a front end, the front end removably secured to the cylindrical housing.

13. The fuze mounting assembly of claim 1 , wherein the fuze housing includes a cylindrical housing having an aft end and a front end, the front end fixed to the cylindrical housing.

14. The fuze mounting assembly of claim 1 , wherein the fuze housing includes a cylindrical housing having an aft end and a front end, the front end integral with the cylindrical housing.

15. The fuze mounting assembly of claim 1 , wherein the integral flange of the fuze housing includes a plurality of holes therethrough.

16. The fuze mounting assembly of claim 1 , wherein the integral flange of the fuze housing mates with a flange seating portion formed in the fuze well.

17. The fuze mounting assembly of claim 1 , wherein the fuze housing includes a threaded portion on the exterior thereof.

18. The fuze mounting assembly of claim 1 , wherein the fuze well includes a threaded portion in the fuze well.

19. The fuze mounting assembly of claim 1 , wherein the fuze well includes a threaded portion in the fuze well and the fuze housing includes a threaded portion on an exterior thereof.

20. The fuze mounting assembly of claim 1 , wherein the penetrating weapon comprises a weapon having fins thereon.

21. The fuze mounting assembly of claim 1 , wherein the penetrating weapon comprises a projectable device.

22. The fuze mounting assembly of claim 1 , wherein the penetrating weapon comprises a penetrating shell.

23. The fuze mounting assembly of claim 1 , wherein the penetrating weapon comprises a projectable device that includes one of a self-propelled device, a shot device, a launched device, and a device dropped toward an intended target.

24. A fuze mounting assembly of a penetrating weapon comprising:

a fuze well including a receiving well having a surface on an interior thereof having a threaded portion, a portion of the fuze well having a plurality of threaded holes therein; and

a fuze including a fuze housing including an integral flange and a threaded portion on an exterior thereof, a portion of the fuze housing being received in the fuze well, the fuze housing secured to the fuze well by a plurality of circumferentially spaced fasteners extending through the integral flange, the fuze mounting assembly configured to exhibit an amplification of acceleration of less than 3.0 when subjected to impact and penetration shock responsive to the penetrating weapon contacting a target.

25. A fuze mounting assembly of a penetrating weapon comprising:

a fuze well having a receiving well, a portion of the fuze well having a plurality of threaded holes formed therein; and

a fuze including a fuze housing having an integral flange, a portion of the fuze housing being received in the receiving well of the fuze well, the fuze housing secured to the fuze well by a plurality of circumferentially spaced fasteners extending through the integral flange, the fuze mounting assembly configured to exhibit an amplification of acceleration of less than 3.0 when subjected to impact and penetration shock responsive to the penetrating weapon contacting a target.

26. The fuze mounting assembly of claim 25 , wherein the fuze housing includes a cylindrical housing having an aft end and a front end, the front end fixed to the cylindrical housing.

27. The fuze mounting assembly of claim 25 , wherein the fuze housing includes a cylindrical housing having an aft end and a front end, the front end integral with the cylindrical housing.

28. The fuze mounting assembly of claim 25 , wherein the integral flange of the fuze housing includes a plurality of holes therethrough.

29. The fuze mounting assembly of claim 25 , wherein the integral flange of the fuze housing mates with a flange seating portion formed in the fuze well.

30. The fuze mounting assembly of claim 25 , wherein the fuze housing includes a threaded portion on an exterior thereof.

31. The fuze mounting assembly of claim 25 , wherein the fuze well includes a threaded portion in the fuze well.

32. The fuze mounting assembly of claim 25 , wherein the fuze well includes a threaded portion in the fuze well and the fuze housing includes a threaded portion on an exterior thereof.
