No. 29, application 95103530/02 of 03/14/95).

At the same time, the TGSN is mounted not cantilever at a considerable distance from the suspension nodes, as in a standard KAB, but with the help of clamps directly under the suspension nodes of the training AB. At the same time, the center of gravity of the TGSN is located on the axis of symmetry of the front and rear suspension nodes of the AB, which allows to improve the operational characteristics of the training bomb, significantly increasing the number of takeoffs / landings of the training AB (up to several hundred) compared to 10 take-offs / landings of the standard SC.

This training aircraft bomb, made in accordance with the patent of the Russian Federation No. RU 2093780, is selected as a prototype.

A training prototype aerial bomb, providing the number of takeoffs / landings up to several hundred, allows pilots (navigators) to be trained only on the use of the KAB with television homing heads.

This training AB does not allow for the training of pilots / navigators on the use of the KAB with laser seeker.

The proposed invention solves the creation of a training bomb for training flights on the use of laser KAB in simple and extremely difficult meteorological conditions.

To achieve this technical result, the training AB prototype contains a laser information device including a matrix receiver of reflected laser radiation mounted on a gyrostabilizer and an electronic signal processing unit. In this case, the training aviation bomb contains a nose information compartment sequentially docked with an optically transparent fairing made in the form of a hemispherical shell, an instrument compartment including an on-board automation unit, a tail fairing, and a suspension beam on which the front and rear nodes of the suspension to the carrier aircraft are located , electrical connector, nose and tail clamps covering the training bomb. The suspended beam is 3.85-3.9 caliber long bombs. The bow information compartment contains a lens and a matrix receiver of reflected laser radiation mounted on a gyrostabilizer, and an electronic signal processing unit, and is made in the form of two mating truncated cones with bases of 0.643 and 1.0 caliber air bombs and a height of 0.286 and 1.0 caliber air bombs, respectively. The hemispherical shell is made with a radius of 0.23 and a height of 0.17 caliber bombs. The instrument compartment is equipped with an onboard recording memory and is made in the form of a cylinder with a diameter equal to the caliber of an air bomb and a length of 1.82 ... 1.83 caliber of an air bomb. The tail fairing is made in the form of a cone with bases equal to 1.0 and 0.457 caliber air bombs and a height of 1.147 ... 1.149 caliber air bombs paired with a spherical shell whose radius and height are 0.257 and 0.3 caliber air bombs, respectively.
