Abstract: A gunfire shock simulation apparatus that uses an actual firearm for generating and measuring shock response data without a pyrotechnic discharge. The apparatus exerts an impact on a discharge end of a barrel of the firearm for simulating the pyrotechnic discharge event of a round of ammunition discharged within the firearm. Following such impact, the apparatus cycles a bolt carrier group of the firearm for simulating movement of the bolt carrier group resulting from the pyrotechnic discharge event of a round of ammunition. A sensing device is used for gathering shock response data in three perpendicular reference axes. By adjusting the manner in which the impact is applied to the discharge end of the barrel and/or the manner in which the bolt carrier group is cycled, resulting shock response data can be tuned to closely approximate that generated by live fire of the firearm.

Abstract: "A vehicle and the ballistic shock isolator therefor including a turret, a sensor assembly and a shock isolator isolating the turret from the sensor switch and including upper and lower annular members, a plurality of leaves secured at opposing ends thereof to the annular members, each of the leaves having a corrugated bellows shaped portion in the form of an even number of similarly shaped portions, alternate ones of the similarly shaped portions having an open end in opposing directions, each of the leaves varying in thickness and width in a direction from the upper annular member to the lower annular member. The variation in width of the portion is alternately from wide to narrow and then from narrow to wide in a direction from the upper annular member to the lower annular member.
