Abstract

A directed-effect submunition moves in a substantially vertical direction V with a displacement velocity v parallel to V and a rotation velocity r about an axis parallel to V. The submunition includes a shaped charge with axis D forming an acute angle t with axis V and a detection device with axis d forming an angle u with axis D, a target detecting device, and a triggering device. The submunition also includes a displacement velocity v determining device, and a calculation device for calculating as a function of v a value u.sub.i for angle u that minimizes deviation (e) between the position (M) of a target detected, and impact point (M') of the penetrator of the shaped charge if the latter were triggered upon detection, as well as a device for imparting the value u.sub.i to angle u.

Dependent claims

A directed-effect submunition projectable, before being detonated, along a substantially vertical axis above a region containing a target, said submunition having a displacement velocity along said vertical axis and a rotation velocity relative to said vertical axis, said submunition comprising:

a charge having an axis of symmetry forming a first angle with said vertical axis;
a detection device having a detection axis forming a second angle with said axis of symmetry;
means for detecting a target;
means for triggering said charge when said target is detected;
means for determining at least one of displacement velocity and altitude of the submunition with respect to the region containing said target;
calculation means for calculating, based on at least one of said displacement velocity and said altitude, a trajectory angle selected from among a set of trajectory angles, said trajectory angle minimizing a deviation existing between a position of a target instantaneously detected and an impact point of the submunition if the submunition were triggered upon detection of the target;
and
means for imparting said trajectory angle between said detection axis and said axis of symmetry.
