  • Method of arming and arrangement for carrying out the method
    Patent number: 5756927
    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.
