Abstract
The present disclosure relates to methods and devices for investigating and characterizing a fragment or debris field caused by an explosion, and in particular, explosions resulting from the detonation of a cased munition. Aspects of the disclosure provide methods and devices which can be used to determine and correlate properties such as size/mass, location and velocity of fragments resulting from such a detonation.
Claims20
A system for determining fragment characteristics, comprising:
- a culvert having a front aperture and a chute portion;
- a pendulum hung from at least two pivot points in the culvert, the pendulum comprising a strike face which has a plurality of attachment points upon which at least one witness panel may be mounted;
- at least one witness panel mounted on the pendulum;
- one or more leaf springs mounted on the back of the pendulum and configured to limit the motion of the pendulum when impacted by fragments resulting from an explosion;
- and
- at least one high-speed camera mounted within the culvert.

A method for determining fragment characteristics, comprising:
- (a) providing a culvert comprising:
- (i) a front aperture and a chute portion;
- (ii) a pendulum hung from at least two pivot points in the culvert, the pendulum comprising a strike face which has a plurality of attachment points upon which at least one witness panel may be mounted;
- (iii) at least one witness panel mounted on the pendulum;
- (iv) one or more leaf springs mounted on the back of the pendulum and configured to limit the motion of the pendulum when impacted by fragments resulting from an explosion;
- and
- (v) at least one high-speed camera mounted within the culvert;
- (b) orienting the front aperture of the culvert towards an explosion;
- (c) measuring the movement of the pendulum and recording the movement of the one or more fragments generated by the explosion within the culvert using at least one high-speed camera;
- and
- (d) determining characteristics of the one or more fragments, based on the movement of the pendulum.
