Muzzle Blast Damage to Combat Vehicles
Abstract
This TOP provides tests for evaluating damage to combat vehicles (self-propelled artillery and assault vehicles) and their components by muzzle blast. Muzzle blast overpressure can affect the structural integrity of weight- restricted vehicles. Measuring blast pressure loading and resultant stress can provide a basis for predicting damage that will occur when the weapon is fired. Two methodologies are presented in this TOP to determine the effects of blast overpressure on a test vehicle. The first methodology assesses combined forces of recoil energy and blast overpressure. This is accomplished by firing an instrumented test vehicle and measuring the resultant strain, acceleration, and blast overpressure effects imparted to the vehicle. The second methodology separates the effects of blast overpressure from recoil forces. This is accomplished by firing an instrumented test vehicle and measuring the resultant strain, acceleration, and blast overpressure. Then, fire a second vehicle, identical to the first, from a position to impart a worst case blast overpressure wave onto the test vehicle; measure the blast overpressure. These tests will yield data describing the pure blast effects and blast/recoil effects upon the test vehicle.
