Abstract
A contact head for a projectile which is capable of being fired from an electrically actuable launcher comprises a solid metal core formed on one side with a recess for constituting a propellent charge chamber in which are located a propellent charge and a primer capsule. The recess is closed by a base plate having breakage points for the egress of gases generated by ignition of the charge. The part of the core surrounding the recess is formed with first and second sets of bores spaced equiangularly about the axis of the core for receiving connecting screws for connecting the, contact head to a projectile and for receiving fixing screws for fixing the base plate to the core, respectively. An elastic protective member coaxially surrounds the head and is preferably subdivided into three rings, e.g. of rubber, which carry two metallic contact rings connected to the primer capsule by firing circuit wires. The use of a solid metal core as opposed to plastics members used in the prior art provides better control of the flight of the projectile and enables the contact head to withstand more rigorous conditions.
