BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a droppable mine having mine housing and a righting balloon surrounding its circumference so as to right and position the mine housing, as well as a fixing device for fixing the mine housing on the ground in a desired position.
Such droppable mines are increasingly deployed by launching from the ground or from the air into a certain target area. Customarily, various carrier systems are employed for this purpose such as, for example, rockets, artillery projectiles or the like.
After being ejected from the carrier system, the mines generally drop to the ground in a decelerated fashion so that even if the landing surface is soft, the mines do not sink into the ground. Since, in view of the usual consistency of the ground and its slope, it can hardly ever be assumed that such mines land on the ground in a position that is advantageous for their action, particularly in connection with so-called intelligent mines, it is necessary to put them upright and position them for efficient action.
It is known to right such mines by providing a balloon that surrounds the mine housing over its circumference and to blow it up by suitable measures to thus enable the mine to be put upright.
Since, however, this upright position of the mine should be ensured also over longer periods of deployment independently of the consistency of the ground, the weather and possible shocks, the more recent development of such mines provides for fixing them in their upright position.
However, because of their special configuration, prior art fixing devices for such mines, such as, for example, fixing nails driven out of the mine housing into the ground, are not suitable for all types of ground and, because of their structural size, are not suitable for flat mine housings but only for high mine housings.
It is therefore the object of the invention to provide a droppable mine of this type which includes a fixing device that is distinguished by a low structural height and suitability for all types of ground.
SUMMARY OF THE INVENTION
The above object is accomplished according to the present invention by a droppable mine of the above described type wherein the fixing device is composed of a foam generator for generating a hardenable foam, a sack disposed at the underside of the mine housing, and conduits for supplying the foam generated by the foam generator to the sack to fill the sack.
The fixing device provided according to the invention and composed of a sack attached to the underside of the mine housing so as to be filled with a hardenable foam once the mine has been righted can be realized in a simple manner and requires only a small structural volume, particularly a low structural height, and can thus be employed even in flat mine housings.
Further advantageous features of the invention are disclosed and described.
The invention will be described and explained below with reference to a drawing figure in which components that are not significant to the invention have not been illustrated.
BRIEF DESCRIPTION OF THE DRAWINGS
It is shown in:
FIG. 1 is a schematic side view of a droppable mine according to the invention after it has been righted on planar ground.
FIG. 2 is a schematic side view of a droppable mine according to the invention on a sloped ground (slope position);
FIG. 3 is a schematic side view of a droppable mine according to the invention after it has been righted and the mine body has been oriented vertically on a slope.
FIG. 4 is a schematic cross-sectional illustration of a droppable mine with a foam generator according to the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 depicts a droppable mine 10 according to the invention which has already landed in the target area on the ground 12 existing there. On the side around a mine housing 14 for the mine 10, an already deployed, that is, blown-up righting balloon 16 is shown. This righting balloon 16 is known per se and operates in the conventional manner similarly to an air bag in an automobile.
