FIELD: electricity.SUBSTANCE: high-speed imitator comprises a case including group of electric contacts made as current-conductive elements place in free space of the initiator. One of current-conductive elements is isolated galvanically with control circuit of actuator and serves as a locking mechanism mounted to move freely in formed volume of the detector when inertial forces are unavailable, and when inertial forces are available to be placed in the farthest remote position from response current-conductive elements in the group of electric contacts, which corresponds to minimum of its potential energy. At that part of the detector volume for movement of the locking mechanism is limited by surface of a cone placed at angle ? to the axis of high-speed initiator of less than 90° from direction of affecting axial inertial force. The control circuit includes an electronic switch connecting ignition train of the actuator and univibrator controlling the electronic switch and coupled in parallel to the group of electric contacts; in the circuit there is additional preamplifier mounted in series between the electronic switch and univibrator.EFFECT: improved operation speed and actuation reliability of the high-speed initiator, simplified design of target detector, universality of the circuit.3 cl, 4 dwg |
