SK279549B6 - Heating device for practice target - Google Patents

Abstract

A heating device for a practice target, which is heated in order to produce a thermal image with the aid of a heat source which produces a gaseous heated medium, the heat source being initiated and/or interrupted by means of a control device (3), at least one pyrotechnic charge (2) which produces hot gas being used as the heat source, and it being possible to influence the thermal capacity and/or burning duration of the pyrotechnic charge (2) by means of its size and/or shape.

Description

Technical field

The invention relates to the heating of a training object which is heated to produce a thermal image by means of a heat source which produces a gaseous heated medium, the heat source being initiated and / or interrupted by the control device.

BACKGROUND OF THE INVENTION

FR-PS 25 44 067 describes various fuels, such as gas or fuel oil, as energy carriers for heating a training target. These fuels have the common disadvantage of being stored in a bulky tank. If the shell is hit or if the shot is too short, the entire energy supply is ignited at once.

SUMMARY OF THE INVENTION It is therefore an object of the invention to provide alternative heating to known fuels which minimizes their hazards and which, moreover, is easy to operate and economical.

SUMMARY OF THE INVENTION

This is accomplished by heating a training object which is heated to produce a thermal image by a heat source which produces a gaseous heated medium, wherein the heat source is initiated and / or interrupted by the control device according to the invention, which is at least one pyrotechnic charge producing hot gas, and that the pyrotechnic charge is influenced in terms of heat capacity and / or burning time by its size and / or form.

Further advantageous embodiments are set forth in the subclaims.

A particular advantage of the heating according to the invention is that it is relatively inexpensive to operate in comparison with other heating systems. Furthermore, a suitable choice of the sizing of the pyrotechnic charges allows easy adaptation of the combustion time and the amount of hot gases generated. Finally, existing explosive substances can be effectively disposed of in charge production.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention will now be explained in more detail by way of example with reference to the accompanying drawing, in which the exercise target with pyrotechnic heating is schematically shown in simplified form. The training objective itself is described extensively in German patent application P 43 28 576.7.

DETAILED DESCRIPTION OF THE INVENTION

The pyrotechnic heater first comprises a control device 3, which can be produced in many ways. This control device 3 controls the pyrotechnic charges 2, i.e. propellants, which, when ignited, produce a stream of hot gas 6, which collects in the ram tube 5 and then leads to the interior of the training target 1.

Pyrotechnic charges similar to pyrotechnic substances can be used as pyrotechnic charges 2. In this case, there can be embodiments which produce a stream of hot gas almost smoke-free. It is also possible to use pyrotechnic compositions which originate from pyrotechnic components suitable for disposal. The form and dimensioning of the pyrotechnic charges 2 make it possible to vary the burning time and the amount of hot gas produced 6. As well as the solid charges, it is also possible to use powder compositions which are filled into cartridges or also pasty or liquid charges.

The pyrotechnic charges 2 may be combined into groups, wherein the individual pyrotechnic charges 2 are always placed below the ram tube 5 by means of means not shown in detail 7. In the case of electrically combustible pyrotechnic charges 2, at least in the firing position under the ram tube 5 an electrical connection is provided. However, the permanent connection of all pyrotechnic charges 2 of one group to the control device 3 is also contemplated.

In the simplest case, the control device 3 is designed as a hand-operated device which, after a delay time, ignites at least one pyrotechnic charge 2. If necessary, a charging device 7 is provided for the various pyrotechnic charges 2. This charging device 7 can be designed so that From the illustrated target, different sized pyrotechnic charges 2 can be activated at any time. The electrical control device 3 may be program-controlled and / or remote-controlled. As an extension of the control device 3, it is provided that the pyrotechnic charge 2 is not only ignited, the combustion is interrupted, if necessary, by means of suitable devices, and the pyrotechnic charge 2 is possibly re-ignited.
