摘要:
A weapon system includes a carrier vehicle and a vehicle dependent mortar, wherein the carrier vehicle has a crew space and a weaponry space to house the mortar, and the mortar is charged in an index position with mortar grenades, with several sheddable propellant modules on the tail shaft thereof. The weapon system avoids manual loading of the mortar with mortar grenades because an automatic loader is arranged in a weapon space separated from the crew space by a separating wall. The loader transports the mortar grenade from a magazine in the weapon space into the index position of the barrel of the mortar and axially inserts it into the mouth of the barrel, and an automatic shedding device is arranged in the weapon space to automatically remove unnecessary propellant modules from the mortar grenade after fixing target parameters and before insertion of the mortar grenade into the barrel.
摘要:
A combat tank is converted into an artillery observation tank without requiring removal of the main gun. The combat tank is converted by integrating retrofitted equipment necessary for the artillery observation, especially the navigation system (12), into the vehicle turret (4) such that it does not collide with the main gun. The navigation system (12) is installed with an arbitrary orientation at an arbitrary location in the vehicle turret (4), and adjusted at this location, without requiring a complicated adjustment mechanism for the observation system, or attachment to the elevating mass. The necessary elevation values for the line of sight (21) are obtained through the evaluation of the angular values of a mirror in the mirror head, such as of a primary-target telescope (20), or through evaluation of gun-position angles.
