Tests showing the projectile flight trajectory of 5, 7 and 8mm diameter steel spheres attached to either a detonator or a rear detonated C4 spherical explosive charge

These videos are the results of an experimental campaign carried out in the department of Propellant, Explosives and Blast Engineering of the Royal Military Academy in Brussels to study the flight trajectory of a projectile (steel sphere (5 or 7 or 8mm diameter)) attached to either a detonator or a rear detonated C4 spherical explosive charge. The projectile is accelerated by the blast wave generated by the explosive. The projectile initial trajectory is hidden by the flash of the detonation. After its passage through the opaque gas cloud, the first appearance of the projectile is captured and an almost straight trajectory can be tracked until the end of the field of view of the high speed camera. The test campaign reveals the capability of the projectiles to maintain an oriented path until impact on a target placed at 910mm stand of distance from the center of the explosion.
