SAFETY AND FUSE ARMING DEVICE FOR ROCKET-TYPE GYRO-STABILIZED AMMUNITION

摘要

The invention concerns the technical field of arming fuses, and more particularly a safety and fuse arming device (1). It is applicable to gyro-stabilized ammunitions, and in particular to rockets. It is applicable to impact rockets as well as to electronic rockets. The invention consists essentially in adding a rotary lock (7) to a device already comprising an inertia lock (2) and an arming delay (11, 3). The inertia lock is released (21) in the presence of a longitudinal acceleration, thereby triggering (20) the arming delay. The rotary lock (22) is released as from a specific rotational speed. However, if the rotary lock has not been released after a specific interval upon triggering of the arming delay, the rotary lock prevents the arming of the rocket.
