Definitions

  • the invention relates to an artillery ammunition according to the preamble of claim 1, as known from US 4,438,893 is known.
  • so ballistically to be spun and spin-stabilized artillery ammunition is in the case of performance-enhanced artillery rockets after DE 43 25 218 C2 as a carrier for cluster munitions.
  • the aim here is to increase the range of the rocket and to optimally use the surface effect of its cluster munitions.
  • the wing-stabilized rocket is orthogonal to each other in the area of its orgive with four oriented Canard rudders equipped, which are set after passing through the apogee of the runway independently GPS-based transition to a stretched gliding trajectory on the coordinate specified delivery area of cluster munition.
  • the demands made on such a range-enhanced artillery rockets as a precision surface weapon therefore require different principles of interpretation than the generic, point-targeted spent spin-stabilized ballistic-fired artillery ammunition.
  • the invention has the object to make the fault budget ballistically over a target area lost ammunition altogether cheaper.
  • the in-phase pitch or yaw attitude in relation to the current roll position in space is under the direction of a roll position sensor in the fuze tip, which indicates how the control shafts of the two canard surfaces are aligned with respect to the earth's horizon, in which direction in space ie the trajectory is extended or shortened by a current employment of Canard vom.
  • a high-speed low-voltage DC motor is preferable because of the small installation space, the self-locking effect of a strong gear reduction and its low cost availability, preferably in the coaxial design of a wave gear motor.
  • a torsionally rigid coupling of the two control shafts may be provided to make do with a single drive system; or the two Canards are independent of each other and then in the interest of a highly dynamic control, if necessary, also in opposite directions adjustable via their own drives.
  • the electrical energy for the Anstell tooung can be provided by batteries or mend even generated in the igniter tip itself as a generator, namely taking advantage of the relative movement between the stabilized by faster rolling ammunition body and the reduced rotational speed of the ammunition body via a rotary dreckkoppelten igniter tip ,
  • a magnetic sensor responding to the earth's magnetic field is to be preferred, since it is more suitable for all weathers compared to optronic horizontal sensors and less expensive compared to inertial platforms.

Claims (5)

  1. Munition d'artillerie stabilisée gyroscopiquement et tirée balistiquement, dont la dispersion longitudinale et la dispersion transversale du groupement des points d'impact peut être corrigée et dotée d'une amorce découplée en rotation par rapport au corps de la munition sur la partie avant rétrécie du corps de munition,
    deux arbres d'ajustement orientés radialement par rapport à l'axe gyroscopique du corps de munition, pour deux surfaces d'aile en canard orientées vers l'avant de part et d'autre de l'axe gyroscopique d'un système canard à un axe ajustable étant prévus sur l'amorce découplée en rotation et ayant le même calibre, ne pouvant être rétractées et étant ajustées par rotation de leur arbre d'ajustement dans les deux directions par rapport à la position neutre pour, selon la position instantanée de rotation du canard dans l'espace et selon la position effective des surfaces d'aile de canard par rapport à la position instantanée en rotation dans l'espace, agir en phase correcte sur la dispersion longitudinale au moyen d'un déplacement asservi de tangage ou sur la dispersion transversale au moyen d'un déplacement asservi de lacet,
    caractérisée en ce que
    elle présente une commande discontinue de la position de chacune des surfaces d'aile de canard par au plus un quart de tour du corps de munition.
  2. Munition d'artillerie selon la revendication 1, caractérisée en ce que des moteurs à courant continu basse tension à haute vitesse de rotation et dotés de rapports de transmission fortement réducteurs à auto-blocage sont prévus comme systèmes d'entraînement pour faire tourner les arbres d'ajustement en vue de positionner les surfaces d'aile de canard.
  3. Munition d'artillerie selon les revendications 1 ou 2, caractérisée par la possibilité d'ajuster les arbres d'ajustement dans des sens opposés.
  4. Munition d'artillerie selon l'une des revendications précédentes, caractérisée en ce que les deux arbres d'ajustement sont reliés l'un à l'autre à rotation solidaire et sont accouplés à un unique système d'entraînement.
  5. Munition d'artillerie selon l'une des revendications précédentes, caractérisée en ce qu'une production d'énergie par générateur est prévue par recours au déplacement relatif entre le corps de munition en rotation rapide et la vitesse de rotation réduite de la pointe d'amorce découplée en rotation par rapport au corps de la munition pour commander l'ajustement des surfaces d'aile de canard.
