Abstract

A scalable, inert munition data recorder cartridge. This inert cartridge allows users to record data from within a weapon system feed chute, breach, and extractor port. This cartridge is adaptable to any weapon system, packaging unit, environmental chamber, or other ammunition holding and storage device. Although the cartridge is designed to interface with a weapon and ammunition packaging based on its shape, it still functions as designed regardless of its location and application. This would allow the cartridge to be placed anywhere an actual live cartridge of ammunition could be placed.

Claims

1. A scalable data recorder for use as part of a cartridge in order to record data from within a chamber in the cartridge during loading, firing, and ejection in a weapon, the scalable data recorder comprising:

a casing;

a data recorder assembly;

the casing includes a body, a cartridge extractor cap, and a nose;

the data recorder assembly includes an onboard data recorder, a sensor package, a power supply;

wherein upon assembly, the casing forms the chamber within the cartridge, and the data recorder assembly is fitted securely within the chamber; and

wherein the overall exterior profile of the data recorder assembly substantially corresponds to the interior shape of the chamber, in order to minimize movement of the data recorder assembly within the casing.

2. The scalable data recorder of claim 1, wherein upon assembly, the cover is secured to the housing in order to form part of the chamber that houses the data recorder assembly.

3. The scalable data recorder of claim 2, wherein the housing is integrally provided with an extension that forms part of the chamber and that houses, at least in part, the sensor package.

4. The scalable data recorder of claim 3, wherein the interior surface of the chamber is generally cylindrically shaped;

and

wherein the profile of the data recorder assembly is generally cylindrically shaped with substantially similar dimensions to the dimensions of the interior surface of the chamber.

5. The scalable data recorder of claim 3, wherein the casing includes at least one alignment and locking feature.

6. The scalable data recorder of claim 2, wherein the power supply is secured within the nose of the cartridge.

7. The scalable data recorder of claim 6, wherein the power supply is further electrically connected to the sensor package and the onboard data recorder to supply electrical energy to the sensor package and the onboard data recorder.

8. The scalable data recorder of claim 7, wherein the sensor package includes at least one sensor for acquiring data.

9. The scalable data recorder of claim 8, wherein said at least one sensor includes at least one accelerometer.

10. The scalable data recorder of claim 8, wherein the acquired data is transmitted from the sensor package to the onboard data recorder.

11. The scalable data recorder of claim 10, wherein the acquired data is stored by the onboard data recorder.

12. The scalable data recorder of claim 11, wherein the casing includes a cartridge extractor cap;

and

wherein the data recorder assembly further includes a data interface port that is secured to the onboard data recorder, that is in electrical communication with the onboard data recorder, and that protrudes in part from the cartridge extractor cap to enable access to the acquired data.

13. The scalable data recorder of claim 10, wherein the acquired data is further transmitted wirelessly by the onboard data recorder.
