Definitions
- the invention relates to a method according to the preamble of claim 1, as is known from DE 198 45 611 AI.
- the detonator tip which can be screwed onto the ammunition body, has a component which can be rotated for swirl reduction in relation to the spin-stabilized ammunition body and from which two braking surfaces rigidly held with the same angle, in the manner of canard wings, transversely to the
- Swirl axis can be extended in order to exert a directed braking effect on the current trajectory of the ammunition, depending on the current roll position in the room, in order to increase the accuracy of the target.
- Swirl axis can be extended in order to exert a directed braking effect on the current trajectory of the ammunition, depending on the current roll position in the room, in order to increase the accuracy of the target.
- the trajectory-selective braking measure can only shorten the trajectory, so that the scatter in the hit pattern can thus only be narrowed in one direction.
- the invention is based on the object of making the error balance of ballistic ammunition fired over a target area more favorable overall.
- the pitch or yaw adjustment which is in phase with respect to the current RoU position in the room, is carried out under the direction of a roll position sensor in the detonator tip, which indicates how the adjusting shafts of the two canard surfaces are aligned with respect to the earth's horizon are in which spatial direction the flight path is lengthened or shortened by a current setting of the canard surfaces.
- a high-speed low-voltage DC motor is preferable, preferably in the coaxial design of a wave gear motor, because of the small installation space, the self-locking effect of a strong gear reduction and its inexpensive availability.
- a torsionally rigid coupling of the two control shafts can be provided in order to get by with a single drive system; or the two canards are independent of each other via their own drives and can also be adjusted in opposite directions if necessary in the interest of highly dynamic control.
- the cost of electrical circuitry can be reduced even more if, instead of the continuous adjustment control for alternately setting the canard surfaces for the period of a maximum of a quarter turn of the ammunition body around its swirl axis, a three-point subsystem that is always only temporarily activated, or even a two-point subsystem that always switches in the correct roll phase is used.
- the electrical energy for the starting control can be provided by batteries or even better generated in the fuse tip itself as a generator, namely by taking advantage of the relative movement between the ammunition body stabilized by faster rolling and the reduced speed of the fuse tip decoupled by the ammunition body via a pivot bearing ,
- a magnetic sensor that responds to the earth's magnetic field is preferred because it is suitable for all weather conditions over optronic horizon sensors and is cheaper and smaller in size compared to inertial platforms.
