ADAPTIVE DEVICE FOR MEASURING THE PARAMETERS OF PROJECTILE MOTION AT THE STAGE OF INTERNAL BALLISTICS Russian patent published in 2022 - IPC F41G1/00 

FIELD: measuring technology.

SUBSTANCE: invention relates to the field of control and measurement technology and can be used to measure linear, angular velocities and accelerations of a projectile in the barrel of a gun. The essence of the invention consists in measuring the parameters of the projectile motion at the stage of internal ballistics by an adaptive device that contains deformation fiber-optic sensors on Bragg gratings, a shot sensor, a control and signal processing unit including a broadband radiation source, a fiber-optic circulator, an optical fiber, a tunable fiber filter, a photodetector, a digital-to-analog converter and a microcontroller. In this case, the analog output of the photodetector is connected to the input of the differentiator of the first derivative of the signal, and its output is connected to the inputs of the zero-level detector of the first derivative of the signal and the differentiator of the second derivative of the signal. The output of the differentiator of the second derivative of the signal is connected to the input of the detector of the negative value of the second derivative of the signal. The outputs of the detectors, together with the output of the shot sensor, are connected to the inputs of the module for counting the time of passage of the measuring sections by the projectile.

EFFECT: increase in the accuracy of introducing firing corrections in the automatic mode of self-propelled artillery guns.
