US12578172 - System and method for obtaining training munition firing signature

A training munition assembly for use with a weapon includes a case, a first firing element, and a release assembly. The case defines an interior cavity. The first firing element is disposed within the interior cavity. The release assembly is coupled to the case and engages the first firing element. The release assembly is configured to cause movement of the first firing element from a first position within the interior cavity to a second position within the interior cavity responsive to actuation of the release assembly from outside of the case. Movement of the first firing element is configured to generate a firing signature that is indicative of actuation of the release assembly.

trainingmunitionfiringsignature

The patent describes a training munition assembly designed to simulate a firing signature through the movement of two firing elements within a case when a release assembly is actuated. This system allows for realistic training scenarios by providing feedback indicative of weapon operation without the use of live ammunition.

Claim 1

1 . A training munition assembly comprising: a case defining an interior cavity; a first firing element disposed within the interior cavity; a second firing element disposed within the interior cavity; and a release assembly coupled to the case and engaging the first firing element, the release assembly configured to cause movement of the first firing element from a first position within the interior cavity to a second position within the interior cavity responsive to actuation of the release assembly from outside of the case, and to cause movement of the second firing element from a third position within the interior cavity to a fourth position within the interior cavity, the movement configured to generate a firing signature that is indicative of actuation of the release assembly. a case defining an interior cavity; a first firing element disposed within the interior cavity; a second firing element disposed within the interior cavity; and a release assembly coupled to the case and engaging the first firing element, the release assembly configured to cause movement of the first firing element from a first position within the interior cavity to a second position within the interior cavity responsive to actuation of the release assembly from outside of the case, and to cause movement of the second firing element from a third position within the interior cavity to a fourth position within the interior cavity, the movement configured to generate a firing signature that is indicative of actuation of the release assembly.
