Suit-1 optoelectronic system for the barrel bending measurement

The system measures the current value of the barrel bending of armoured and artillery armaments which appears as a result of the barrel heating during the fire, irregular heating under the solar radiation effect, and also mechanical deformations of the barrel. The electric signal proportional to the measured banding value is transmitted to the fire control system that allows to indemnify the firing errors by correcting the aiming angles. The system can be adapted to different artillery armaments. Thus the firing accuracy is several times increased.
