FIELD: weapons and ammunition.
SUBSTANCE: invention relates to ground tests, particularly for determination of ballistic characteristics of projectiles. Method for determining the dependence of the ballistic characteristics of projectiles on the shooting regimes, consisting in the formation of n non-contact measuring fields in the form of two-dimensional grids based on the design of non-contact sensors in the form of two rulers of radiators and photodetectors located in the vertical and horizontal planes, determination of the velocity and coordinates of the flight of projectiles relative to n measuring fields on the basis of fixation of the moments and triggered combinations of the elements of the photodetector matrices, determination of nutation angles on the basis of measurement of the main elements of the projectile motion relative to the center of mass, in order to determine the nutation angles, the characteristic dimensions of the holes on each target are determined at each angular position of the projectiles, determine the angle of nutation in accordance with the type of the hole based on the comparison of the combination of the triggered photodetector elements with the given values, determine the zero value of the nutation angle, if the hole has the shape of a circle, this type of hole is formed if the projectile axis coincides with the velocity vector of the center of mass, determination of the value of the nutation angles with an increase in the size of the hole in the direction of the deviation of the projectile axis from the tangent to the trajectory, determine the dynamics of nutational motion on the basis of measuring the magnitude of the major axis of the hole along the trajectory of the projectiles, when shooting, determine the shooting mode (number and duration of the queue), determine the dependence of the nutation angles on the shooting modes, take into account the shooting time, the number of shots and shooting regimes of aircraft artillery weapons in service.
EFFECT: technical result when implementing the claimed technical solution is to increase the informativeness.
