Munition and method for fuse of high-spin projectiles wherein

摘要

In the case of known course correction devices and methods (k), for the correction of the lateral deviation, as well as along spill located on the exterior of fuze housing small canard wings - used. The fuze housing with the canads is decoupled from the remaining twist projectile, i.e, freely rotatable. By means of the swirl as well as of the oncoming flow of the canards, by means of a generator to generate electric power, so that a counter torque can be generated, which, in order to carry out a course correction intervention is used. A disadvantage of 2d - course correction igniters is that the integrated generator for generating energy requires a relatively large amount of structural volume. The present invention is therefore an object of the present invention to provide a munition and method of the invention to provide a very low weight and constructional volume required.The problem is solved by the use of a power supply unit (11) and of an actuator (5) in the fuze housing (2) which, in interaction with the igniter nose cone (1), whereby the necessary data of the rotational speed and the angle of rotation of a ring-shaped magnetic magnet wheel (4b), which with a magnetic sensor (4a) corresponds, supplies. The actuator (5) according to the invention is composed of a piezoelectric material, which, by applying an external voltage changes its shape and thus against the detonator nose cone (1) and the speed of rotation of the igniter nose cone (1) is reduced to such an extent that the prefix of vanes, that is to say the second pair (3b), are held turning. As a result, on account of the preceding wing pair (3b) in the projectile is steered in a preferred direction. Course correction of a spinning projectile equipped
