Method and device for using warheads released from a launching vehicle to combat targets identified along the flight path of the launching vehicle

Abstract: The present invention relates to a method and device for combating identified targets (F) using warheads (2) from a launching vehicle (1) flying over a target area, by separating from this launching vehicle (1) warheads (2) which act independently after separation, and including those targets which lie close to the flight trajectory of the launching vehicle (1) and those which lie well to the side of same flight trajectory. The invention is based on the use of that part of the kinetic energy of the launching vehicle (1) which the warhead (2) takes over from the same when it is separated in order to give the warhead (2) a looping trajectory or any other programmed flight trajectory, which carries it up to a starting height adapted to its active use, which lies considerably above the actual flight trajectory of the launching vehicle (1), and which, if so required, can carry the warhead (2) back to the geographical position where it was separated from the launching vehicle (1). The action of the warhead (2) can then follow guidelines known per se.

Method of arming and arrangement for carrying out the method

Abstract: A method and apparatus for determining whether a warhead in flight and forming a part of a rocket, missile, or the like, is in a state which permits arming of the warhead. The arming of the warhead depends upon the conditions of the warhead's movement and the elapsed time from its launching. A specific time slot which begins at a predetermined time after the launching of the warhead and terminates at a predetermined time thereafter is demarcated. The velocity of the warhead is measured following its launch and at least during the specific time slot. The warhead will be armed only in the event that the measured velocity of the warhead has reached at least a predetermined value within the specific time slot.

Electro-optical sight

Abstract: An electro-optic sight, for detecting incoming optical radiation is described. It comprises frontal optics (1) through which radiation along the optical axis, the sight line (3) of the sight passes on its way to platform optics (2) rigidly connected to the frontal optics, which platform optics guide the incoming radiation further to a detector unit (5) in which the incoming radiation is converted to a picture. The electro-optical sight is primarily characterized in that the platform optics (2) are so arranged that, through turning about a first axis, yaw axis (7), and a second axis, pitch axis (8), they direct the optical axis for forwarding to the detector unit (5), the radiation being guided through a system of a first, second, third and fourth prism (13-16) through reflexion, said prisms being mounted in a common structure, which is turnable about the first axis, which coincides with the optical axis, that is said sight line (3), the first prism (13) being turnable relative to the second prism (14) about the second axis, which constitutes the direction of the optical axis reflected from the first prism.
