Abstract

The invention relates to a common carrier munition ammunition device, more particularly to common carrier payload delivery shell.
There is provided a common carrier munition comprising a tail unit, a main body which comprises a payload cavity for receiving a payload, a fuze, and located between said main body and the fuze an ogive element, wherein the tail unit and main body comprise cooperatively engaging male and female threaded portions, wherein at least one of the threads is a shearable thread.

First claim

1 . A common carrier munition comprising a tail unit, a main body which comprises a payload cavity for receiving a payload, a fuze, and located between said main body and the fuze an ogive element, wherein the tail unit and main body comprise cooperatively engaging male and female threaded portions, wherein at least one of the threads is a shearable thread.

2 . A munition according to claim 1 , wherein the main body comprises a threaded portion manufactured from a first material, and the tail unit comprises a threaded portion manufactured from second material, wherein the second material has a lower hardness value than the first material.

3 . A munition according to claim 2 , wherein the first material is selected from a steel alloy and the second material is selected from aluminium or alloy thereof.

4 . A munition according to claim 1 , wherein there is a locking ring located between the main body and said ogive element, to retain said payload within the payload cavity.

5 . A munition according to claim 4 , wherein the locking ring and main body comprise cooperatively engaging threaded portions.

6 . A munition according to claim 1 , wherein the ogive element is reversibly engaged with the fuze and main body.

7 . A munition according to claim 1 , wherein the ogive element has a forward end locatable with said fuze and an aft end locatable with said main body, wherein the internal diameter of the aft end of said ogive element is substantially the same as the internal diameter of said payload cavity.

8 . A munition according to claim 1 , wherein the fuze is operably connected to at least one expulsion charge, wherein said charge is suspended in free space.

9 . A munition according to claim 1 , wherein the payload cavity has substantially parallel walls, which extend from the intersection of the tail unit to the locking ring.

10 . A munition according to claim 1 , wherein the payload is a modular unit.

11 . A munition according to claim 10 , wherein the modular unit, is reversibly loadable from the aft end of the main body.

12 . A munition according to claim 1 , wherein the payload is capable of being dispensed rearwardly from the main body, upon shearing the shearable thread.

13 . A method of dispensing a payload from a munition according to claim 1 , comprising causing initiation of an expulsion charge, and causing shearing of the shearable thread, wherein the fuze is operably connected to the expulsion charge.

14 . A common carrier shell comprising a uniform payload cavity for receiving a uniform payload, wherein said payload is selected from a smoke, illumination or UAV payload.

15 . A common carrier shell according to claim 14 , wherein the uniform payload cavity has a fixed uniform volume, such that it may receive a fixed uniform volume payload, thereby allowing the carrier shell to be configured with a variety of interchangeable payloads.

16 . A common carrier shell comprising:
a tail unit; a main body including a uniform payload cavity for receiving a modular payload, wherein the payload is selected from a smoke, illumination or UAV payload; a fuze; and an ogive element located between the main body and the fuze, wherein the tail unit and main body comprise cooperatively engaging threaded portions, wherein at least one of the threads is a shearable thread.

17 . A common carrier shell according to claim 16 , wherein the main body comprises a threaded portion manufactured from a first material, and the tail unit comprises a threaded portion manufactured from second material, wherein the second material has a lower hardness value than the first material.

18 . A common carrier shell according to claim 16 , wherein the ogive element has a forward end locatable with said fuze and an aft end locatable with said main body, wherein the internal diameter of the aft end of said ogive element is substantially the same as the internal diameter of said payload cavity.

19 . A common carrier shell according to claim 16 , wherein the ogive element is reversibly engaged with the fuze and main body.

20 . A common carrier shell according to claim 16 , wherein the fuze is operably connected to at least one expulsion charge, wherein said charge is suspended in free space.
