Description

ADJUSTMENT TRAINING METHOD 71012

The invention relates to a method for practicing manually aimed aimers for weapons for combating air targets, such as anti-aircraft guns, based on the transmission of short light pulses towards the paint and for detecting echo pulses reflected back from the reflective surface in the paint.

The most effective method to practice the orientation of manually aimed anti-aircraft weapons is to use real ammunition in the weapons and a bag to be towed behind the plane, for example. However, the safety requirements imposed by munitions limit the use of the method only to special situations, such as camp shootings, which in practice cannot be held often enough. The price of ammunition is also a significant cost factor.

Thus, the orientation is often practiced in such a way that with an unloaded weapon (e.g. a cannon 23ltk6l commonly used by the Defense Forces), the orientator follows the training ground moving through the crosshairs. The target used is, for example, an object that can be moved by means of a wire, an airplane or even an airplane. The great weakness of the method is that it does not provide information on the success of the trend. Thus, for example, it is not possible to follow the development of the skills of the director.

The disadvantages of the above-mentioned methods can be eliminated by using a light pulse as a "projectile" in a manner characterized mainly by the aspects set forth in claim 1.

The invention will be described by way of example with reference to the accompanying drawing, in which

Figure 1 shows a device based on the method for use with 23ltk6l.

Figure 1 shows the parts of the apparatus according to the method applied to 23ltk6l. A transceiver unit 2 is attached to the cannon's reflecting target 1 and an electronic part k is attached to it via a cable 3. A trigger switch 5 with its cables 6 is attached to the cannon's release pedal. 8.

The transceiver unit 2 attached to the reflector sight 1 of the cannon is attached so that the light pulses emerge in the direction indicated by the grid of the sight 1. When practicing the orientation, the cannon's ruler searches for the target at the grid and fires a series of pulses at the target's characteristic pulse velocity towards the target by pedaling the cannon's release pedal. Information on the position of the release pedal is transmitted via switch 5.

If the paint is sufficiently accurate in the direction indicated by the grid, echo pulses are received from the reflector attached to the paint to the receiver 2. The received pulses are transmitted via cable 3 to the electronic part k. two numeric displays, one showing the number of light bags fired and the other the number of pulses hitting the target.

The front panel also has e.g. an operating switch, a counter reset button, and a switch to select the magnitude of the space angle at which the pulses are interpreted as hits. The magnitude of the hit angle can be adjusted in three different ways: by changing the size of the reflector surface in the paint or the position of the individual reflectors relative to each other, adjusting the transmitter and / or receiver optics, and adjusting the receiver threshold to determine how strong echoes are interpreted.

The advantage of the structure according to Figure 1 is that the cannon setter can train simultaneously with the rectifier. The corrections made by the setter to the setpoints (i.e., the magnitude and direction of the advance vector) do not affect the operation of the rectifier other than as a disturbance transmitted in the form of the movement of the reflector sight 1 (and the transceiver unit 2).

Thus, the training corresponds as closely as possible to the real situation. If necessary, the transceiver unit 2 can also be attached to the cannon tubes, for example.

It will be clear to a person skilled in the art that the various embodiments of the invention are not limited exclusively to the example shown, but may vary within the scope of the claims set out below. Thus, the device configuration can vary considerably depending on e.g. the type of anti-aircraft weapon used and the training ground1i.

Claims (4)

A method for practicing the aiming of manually-aimed weapons for combating paint targets, such as anti-aircraft guns, characterized in that an optical, visible or infrared transceiver (2) is attached to the weapon aiming device (1) and the training target is attached or otherwise provided, a reflector surface (7, 8) consisting of one or more parts, whereby the receiver (2) provides information on the basis of the radiation emitted by the transmitter (2) in the direction indicated by the sighting device (1) and the return beam from the reflector surface (7, 8) and / or at the space angle determined by the field of view of the receiver and thus the paint with the desired accuracy in the direction indicated by the full-field device. A method according to claim 1, characterized in that the training target is a moving object (7), an airplane (8), a real airplane or a helicopter relied on a wire or similar attachment, to each of which is attached or otherwise provided a highly light-reflecting object visible in the desired directions. surface. Method according to claim 1 or 2, characterized in that the difficulty of hitting the target, i.e. the size of the hit space angle, is changed by changing the transmitter divergence and / or receiver field of view and / or the size of the reflector surface and / or the position of separate reflector surfaces and / or receiver , which determines how strong echo pulses are interpreted as hits. Method according to Claims 1 to 3, characterized in that the device has two separate counters with a numerical display, one of which indicates the number of light pulses transmitted per target and the other the number of pulses which have hit the reflector surface.
