ABSTRACT:
A segmented electromagnetic launcher, comprising a solid rail (20) and a segmented rail (21), formed from segments (22a to 22z) with number of segments greater than one, isolated from one another. These two rails are positioned parallel to and spaced apart from one another, forming a barrel (3) with breech (4) and muzzle (5) ends for sliding a projectile with armature (23) inside the barrel. Two supply conductors (24a, 24b) are positioned on either side and parallel to the solid rail (20) and isolated from it; side supply conductors (25a to 25z, 26a to 26z) are positioned on either side of the bore of the barrel with the number of side supply conductors two times the number of the segments. Each segment (22k) is connected with two supply conductors (24a, 24b) by two side supply conductors (25k, 26k) in connection points (27a to 27z, 28a to 28z) located at the breech end of each segment. The solid rail and both of supply conductors having electrical terminals are disposed close to one another and form one group from three electrical terminals. Two of the same polarity terminals of two single phase identical sources of electrical power (29a, 29b) are connected together and to the terminal of the solid rail (20). Another two terminals of the opposite polarity of the single phase identical sources of electrical power are connected to the terminals of the supply conductors (24a, 24b). The rails, supply conductors and side supply conductors are formed from conductive material and isolated one from another with insulating layers (not shown here).
