  • Patent number: 4753171
    Abstract: A carrier projectile for aerodynamically braked submunition which can be ejected rearwardly from the tail end of the carrier projectile while contacting a cup-shaped base of the projectile. The carrier projectile has the inner edge of the fabric of a braking sail retained within the cup-shaped recess of the base of the projectile, with the outer edge of the fabric of the sail being equipped with centrifugal masses or flyweights mounted in proximity to the opening of the cup-shaped recess in the base. Provision is made to arrange the fabric of a radially outwardly tensionable braking sail in the already available recess in the base of the projectile, the braking sail being extended through the pulling action exerted thereon from the centrifugal flyweights.
    Type: Grant

  • Patent number: 4726543
    Abstract: A braking arrangement for a spin-stabilized projectile, which provides for an increase in the effective surface on the projectile which is contacted by onflowing air, and which is activated in dependence upon the time of flight. There is provided a braking sail which is radially outwardly stretchable or expandable by means of centrifugal masses or flyweights.

  • Patent number: 4711413
    Abstract: A target tracking arrangement which is located in the scanning or search head of a guided airborne body, such as a missile, including a detector located behind a lens arrangement. The arrangement has two rotatable superimposed discs arranged in the path of the beam of the lens arrangement, and which discs are rotatable at different rotational speeds, and possess differently eccentrically extending slits which are transmissive or permeable to beams or rays.

  • Patent number: 4689845
    Abstract: An impulse propulsion unit or pulse-generating impeller mechanism for the lateral acceleration of a projectile, including a hollow cylindrical member, having an outer shell surface which is passed through by nozzles which are peripherally offset relative to each other, and each of which connects into a propellant chamber in the interior of the hollow-cylindrical shell or casing. The propellant chamber is in the shape of an axially elongated section of the hollow wall of a cylinder in which the annular space between the cylindrical inner and outer walls is subdivided through the intermediary of radial separating walls into peripherally neighboring chamber.

  • Patent number: 4674408
    Abstract: An article of ammunition which is controllable during its final flight phase, which is equipped in its cross-sectional plane through the center of gravity with a radially oriented impulse system which is rotatable about the longitudinal axis of the article of ammunition; article, which is activatable through a control circuit located on board of the ammunition article, upon the detection of a target object which is located on the opposite side relative to the instantaneous orientation of the impulse system through the intermediary of a sensor device. Also disclosed is a method for navigating an article of ammunition which is controllable during its final flight phase towards the target object.

  • Patent number: 4611772
    Abstract: A method for increasing the effectiveness of the utilization of target-seeking ammunition articles, which include a sensor scanning a predetermined searching surface within the target area for target criteria in order to suppress dummy targets during evaluation for steering towards or homing on the target. Upon the detection of a target within pregiven target surroundings, a search is conducted thereabout for a further target, and after detecting a predetermined number of such types of neighboring targets, one such target is approached.
