Abstract
The present invention relates to an improved range extension device, particularly to a modular rocket assist device. A range extension device, capable in use of being reversibly engaged to a body of an artillery carrier shell, said shell comprising a payload cavity, said range extension device comprising an internal cavity comprising at least one energetic material charge, and an igniter, wherein the range extension device comprises a first region with an aperture which faces rearwardly, and second region with a closed end, wherein the closed end in use extends into the payload cavity of the carrier shell.
Claims20
A range extension device, capable in use of being reversibly engaged to a body of an artillery carrier shell, said shell comprising a payload cavity, said range extension device comprising:
- an internal cavity comprising at least one energetic material charge;
- an igniter;
- a first region with an aperture which faces rearwardly;
- and
- a second region with a closed end, wherein the second region is configured to extend into the payload cavity of the carrier shell.
A range extension device, capable in use of being reversibly engaged to a body of an artillery carrier shell, said shell comprising a payload cavity, said range extension device comprising:
- an internal cavity comprising at least one energetic material charge;
- an igniter;
- a first region with an aperture which faces rearwardly;
- and
- a second region with a closed end, wherein the second region is configured to extend into the payload cavity of the carrier shell;
- wherein an outer diameter of the second region is less than an outer diameter of the first region;
- wherein the internal cavity of the range extension device is uniform along a length of the device;
- and
- wherein the range extension device is a rocket assist.
A range extension device, capable in use of being reversibly engaged to a body of an artillery carrier shell, said shell comprising a payload cavity, said range extension device comprising:
- an internal cavity comprising at least one energetic material charge;
- an igniter;
- a first region with an aperture which faces rearwardly;
- and
- a second region with a closed end, wherein the second region is configured to extend into the payload cavity of the carrier shell, and wherein the second region extends into the payload cavity in the range of from 5 to 40% of a length of the payload cavity, the length being the length of the payload cavity when the payload cavity is empty;
- wherein an outer diameter of the second region is less than an outer diameter of the first region;
- wherein the internal cavity of the range extension device is uniform along a length of the device;
- and
- wherein the range extension device is a rocket assist.
