A solid state ignition safety device for rocket assisted projectiles having a piezoelectric generator that charges a capacitor during the initial acceleration of the projectile by the launching propellant charge. The capacitor is then discharged after a delay to ignite an initiator, which ignites the rocket motor of the projectile. A time delay circuit can be integrated into the ignition safety device to further delay the ignition of the initiator until the projectile has reached the ideal point in its trajectory to ignite the rocket motor.

Solid state ignition safety device

A weapon system having a gun barrel and an in bore air regulation system. The gun barrel has a first end and a second end. The gun barrel has a bore formed therein that extends from the first end towards the second end. The bore is adapted to receive a round. The in bore air regulation system is operably attached to the gun barrel so that the in bore air regulation system is in communication with the bore to regulate air pressure in the bore and thereby control the position of the round in the bore.
