Ballistics Testing

BYS - Ballistic Yaw Sensor

DSC_1718_Crop_002.jpgQuick and accurate measurement of the bullet yaw is provided by the stand-alone Ballistic Yaw Sensor (BYS) capable of handling a 2 grain RCC up to a 0.5 calibre bullet at 1500 m/s (5000 fps). The angle of bullets, FSPs and RCCs are measured to better than ±0.5° relative to the line-of-flight including the shot location. Measurements are traceable and alignment takes less than 15 minutes. The custom software automates image capture and analysis and provides image storage and reprocessing capability.

BLSH / V50 Headform

Overlay-copyThe Ballistic Load Sensing Headform (BLSH) is used to evaluate the behind armour blunt trauma caused by a defeated ballistic strike to a helmeted head. Injury risk prediction is based on the comparison of skull loading to human fracture tolerance.

The V50 of a helmet is first established with a penetration headform which offers proper helmet support and standoff as well as jaw and nape features for attachment of the retention system. The units are economical and suitable for multiple perforations before disposal.

BLSH_PenetrationFollowing V50 testing, the BLSH is used to measure skull loads resulting from shell deformation. The headform has an array of seven load sensors located behind the ballistic strike location. Optional headform models are available for front-rear, left right and crown locations.

BLSH – Replacement Components

fenn_7655webThe Ballistic Load Sensing Headform (BLSH) has components that will need to be replaced in the course of routine testing. The V50 penetration headform and the four skin pads covering the load sensors must be inspected routinely and replaced after heavy use or visible damage.

fenn_7619webIn the event that a projectile penetrates the ballistic shell, replacement parts for the load sensor array such as the base plate, hexagonal pads and load cells are available .


BTTR - Blunt Trauma Torso Rig

Blunt trauma evaluation with the BTTRFollowing V50 testing, the Blunt Trauma Torso Rig (BTTR) is a newly developed method to assess behind armour trauma effects as an alternative to measuring the BFS. The BTTR provides a more realistic assessment of injury risk by simulating the response of the human chest and recording dynamic deflection data.

Clay Heating Blanket

Typical clay block setupFor ballistic testing to the NIJ and military standards body armour is positioned over a clay backing having a specific stiffness. To achieve this precise stiffness (both across the test area and through its thickness), each clay block must be warmed to a unique temperature.

Clay heating blanketThe most convenient system is Biokinetics' clay heating blanket. Each unit has independent temperature control for use at the storage table or at the target site and attaches quickly with hook and loop fasteners.
