Abstract

In the clearance of explosive bodies (5), particularly mines, in order to improve the safety of the operating personnel and protection of the clearing device, it is proposed to use a laser beam (4) to clear the bodies. The laser beam make it possible for clearance to be carried out for a distance corresponding to visibility range, so affording substantial safeguards for clearance vehicle (1) and crew alike. By pin-pointed action of the laser beam (4), it is possible in a very short time to initiate the explosive substance, which is followed by detonation, or should it be desired, to avoid an explosion, then as an alternative it is possible to destroy just the sensor part and/or the detonator part of the mine. The laser device has a focussing system (3) pivotable about three axes, and lies within the range 5-10 KW. <IMAGE>

Description

SPECIFICATION Method of and apparatus for clearing explosive bodies The invention relates to a method of and an apparatus for clearing explosive bodies or explosive charges, particularly mines laid in the open or visible and equipped with a sensor and detonator part, by means of an emission device.
Mine clearing apparatuses of this type, in which the mines are cleared by means of an emission device, are known, the mines being cleared by means of the jet of waste gases from jet propulsion units (DE OS 21 21 089) or rocket propulsion units (DE-OS 23 63 557). It is also known to clear mines by means of a jet of liquid (DE-OS 33 35 464).
Such mine-clearing methods are disadvantagous in that they require considerable outlay on equipment and technology. The equipment used, in particular, has to be at a relatively short distance from the explosive body which needs to be cleared. Consequently, the clearing vehicle carrying the device and also the crew are exposed to considerable danger.
Therefore, the invention is based on the problem of so improving the clearing of explosive bodies and charges, particularly mines, that the safety of the operators and protection of the clearing device are enhanced while the equipment and technology involved are reduced.
According to the invention, this problem is resolved in that the explosive bodies are cleared by means of laser beams. The laser beams make it possible for clearing to be carried out from a distance corresponding to the visibility range, so largely providing safety for clearing vehicle and crew. The period for which the laser beam can act on the explosive body depends thereby on the composition of its material. However, it is in any case very short, being only a matter of seconds.
The device for emitting the laser beams is ideally a self-sufficient mobile laser device, constructed for mounting on a motor vehicle, e.g. an armour-plated lorry, and equipped with a focussing system pivotable about 3 main axes. The laser preferably lies in a range from 5 to 10 KW.
The laser represents an ideal way of clearing mines, in that either the sensor part and/or the detonator part is/are destroyed or the explosive substance is initiated. By destruction of the sensor and/or detonator part, the mine can be rendered harmless without being detonated. Initiation of the explosive substance causes the mine to explode The laser beam is also especially advantageous in terms of its aiming accuracy compared with known clearing methods. For instance, in an ideal development of the invention, the laser beam can be directed at whichever mine has to be cleared by means of its focussing system, which is pivotable about its three main axes.
Preferably, a laser guide beam can be used to direct the actual laser beam at and fix it accurately on the point of the explosive body where the destructive or initiating action of the laser beam is to take effect.
An example of the invention is shown in the drawing.
On a lorry 1 there is a suitable, easily loaded and self-sufficient laser device 2 which is coupled to a focussing system 3 which is pivotable about its three main axes. Thus it is possible for the operator to direct a laser beam 4 with pin-point accuracy at a mine 5 and allow it to act until the mine is cleared.
Clearance may consist of destruction of the sensor and/or detonator parts or the mine can be detonated by initiation of its explosive charge.
