ARTILLERY GUN Russian patent published in 2004 - IPC

FIELD: artillery, in particular, artillery guns with a guidance system. SUBSTANCE: a gyroscope is installed on the gun for a plane- parallel movement relative to the joint base in three mutually perpendicular directions minimum on one parallel link mechanism. The lower and upper foundations of the mentioned mechanism are spring-loaded relative to each other in the vertical and horizontal directions so that the levers of the parallelogram in the state of rest are located at an obtuse angle to the plane of horizontal guidance in the sector of fire. The relationship between the resonance vibration frequency of the gyroscope and the natural vibration frequency of a loaded gyroscope of the upper foundation at firing exceeds unity. EFFECT: enhanced accuracy of fire, and prevented failure of the gyroscope. 3 cl, 2 dwg
