MEASURING AND RECORDING COMPLEX FOR DETERMINING INTRABALLISTIC AND TRAJECTORY PARAMETERS OF PROJECTILE Russian patent published in 2021 - IPC G01P3/64 

FIELD: testing.

SUBSTANCE: invention relates to the field of testing equipment and, specifically, equipment for determining the trajectory parameters during shooting and can be used to experimentally determine intra- and extraballistic parameters. The measuring and recording complex is comprised of linear extended light sources and optical electronic converters combined with the ballistic pass, forming light screens, coaxial communication lines, a calculator and an information display apparatus with a tester console. A pressure sensor is installed in the charging chamber of the accelerating apparatus of the ballistic path. A muzzle velocity sensor is installed at the output of the channel of the accelerating apparatus. Along the trajectory of the projectile, a millimeter range radar is installed and at least two measuring apparatuses are placed, consisting of consequently located photo-blocking apparatuses forming no less than four light screens using the linear extended light sources and optical electronic converters. The light screens are oriented perpendicular to the trajectory of the projectile. At least two high-speed video cameras located at an angle of (45÷90)° to the trajectory of the projectile are installed along the trajectory of the projectile. Markers are applied on the surface of the projectile, allowing estimating the speed of movement, the rotation speed and the spatial position of the projectile. Witness screens made of a radio-transparent material are also installed along the trajectory of the projectile, by the breaks wherein the true trajectory of the projectile is determined. The target of the ballistic path is equipped with a sensor recording the time of collision of the projectile with the target.

EFFECT: provided is information on the pressure in the ignition chamber, data on the movement of the projectile in the channel of the accelerating unit, and data on the movement of the projectile in several spaced apart external trajectory sections, obtained in a single time interval.
