Sub-combat unit
First Claim
1. A sub-combat unit disposed to be separated from a flying body, over a target area, the sub-combat unit comprising a warhead, a target detector and two diametrically located carrier surfaces (1, 2) which impart to the sub-combat unit a rotation for scanning the target area in a helical pattern during the fall of the sub-combat unit down towards the target area, and both of the carrier surfaces being pivotally disposed from a collapsed position to an opened position in which both of the carrier surfaces from a retarding area for the fall velocity of the sub-combat unit, characterized in that the relationship between the largest main inertia moment and the other main inertia moments of the sub-combat unit lies in the range of between 1.05 and 1.15.

Abstract
The invention relates to a sub-combat unit which is disposed to be separated from a flying body, for example a carrier shell or the like, over a target area, the sub-combat unit comprising a warhead (4), a target detector (5) and two diametrically located carrier surfaces (1, 2) which impart to the sub-combat unit a rotation for scanning the target area in a helical pattern during the fall of the sub-combat unit down towards the target area, and both of the carrier surfaces (1, 2) being pivotally disposed from a collapsed position to an opened position where both of the carrier surfaces form a retarding area for the fall velocity of the sub-combat unit. The sub-combat unit is designed such that the relationship between the largest main inertia moment and the other main inertia moments of the sub-combat unit lies within the range of between 1.05 and 1.15. Hereby, the direction of the axis of rotation of the sub-combat unit will, during a transitional phase, be deflected and assume an almost vertical direction, at the same time as pendulum movements in the axis are damped out.
