“…To investigate the correlation of damage and the effectiveness of damage related to the distribution of shell fragments for a target in space, work [13] proposed the simulation of the calculation of damage to the shell and the intersection of the target. However, the correlation model built is not correct for use in the analysis of directed shells.…”

“…Our review of appropriate studies [7][8][9][10][11][12][13] has revealed an urgent need to devise a universal model of the process of shooting a mobile armored target (AFV) with fragmentation-beam shells of direct action. Such a model, in terms of its capabilities, would create preconditions for experimental studies into the effectiveness of various options for the implementation of components in the artillery system that fires FBS in the series of shots.…”

This paper describes the process of shooting a mobile armored combat vehicle with directed fragmentation-beam shells as a discrete-continuous random process. Based on this approach, a stochastic model has been proposed in the form of a system of Kolmogorov-Chapman differential equations. A universal model of the process of defeating a moving armored target with directed fragmentation-beam shells has been built, which would provide preconditions for experimental studies into the effectiveness of various variants of the components of the artillery system for three-shot firing. The execution of an artillery task is considered as a set of certain procedures characterized by the average value of its duration. They are dependent on the firing phases involving a prospective automatic gun and the explosive destruction of fragmentation-beam shells while the explosive destruction of each shell case is characterized by the self-propagation of the reaction of explosive transformations based on tabular data on the target. An indicator of the functionality of various design options for fragmentation-beam shells is the probability of causing damage by «useful fragments» in the vulnerable compartments of a combat armored vehicle. Devising universal models for the process of shooting a moving armored vehicle forms preconditions for further full-time experiments in accordance with the design solutions defined as a result of modeling. It is possible to use the developed discrete-continuous stochastic model in other modeling tasks to determine the optimal value of defeat. As regards the practical application of discrete-continuous stochastic models, one can argue about the possibility of reducing the cost of performing design tasks related to weapons by 25 % and decreasing the likelihood of making mistakes at the stage of system engineering design

“…The distribution measurement of projectile motion is a significant evaluation indicator for the development, acceptance, and finalization of weapons [1][2][3][4][5]. At present, according to whether the projectile is in contact with the measuring system, the distribution measuring methods of the projectile are mainly divided into contact measurements and noncontact measurements [6][7][8][9][10].…”

This paper proposes a cost-effective, compact, noncontacting optoelectronic targeting system for measuring the distribution of projectile motion. The major elements of this system include a light emitting diode (LED) array, photodiode detecting array, double-layered aperture arrays, adaptive threshold circuit, and date acquisition. Through cooperating with double-layered aperture arrays, the system effectively reduces the radiation width of the light source to the photodiode detecting surface, and filters out the influence of incident light from the adjacent apertures on both sides above each photodiode to the corresponding photodiode detecting surface. It realizes that the response of the photodiode array corresponds to the coordinates of the light screen one by one. Through the sensitivity analysis of the light screen of the system, the system detecting threshold when the projectile passes through the light screen is calculated, and the corresponding adaptive threshold circuit is designed to prevent misjudgment when the system works. The measuring error of the system can reach ±2 mm by experimental verification. Compared with other projectile's distribution measuring systems, the proposed system has the advantages of having high precision, convenient debugging, is nondestructive, and is a noncontact system.
