Abstract

This work analyzes the possibility of a provision of force-majeure mode of the combat vehicles with the aid of disk construction installed in the baffler, the base of the operation of which is the method of residual cyclical quadratic chain code of construction of the “windows” of the movable disk. To determine the optimal parameters of the moving disk of the rotor system, mathematical modeling was performed. The results of mathematical modeling were used to create a PC-based calculation program. The calculation was performed for the rotational frequency ω = 300 s−1 andfor harmonic numbers from 1 to 100. The waveforms used in simulation were as follows: quasi-trapezoidal and rectangular. It is established that at the number of “windows” m = 276 in the moving disk of the rotor system the radiation spectrum acquires a uniform distribution. The object of the research is the process of extreme burning of fuel material in the combat vehicles’ engines, ensuring, according to the technical possibilities of the engine, the implementation of the force-majeure mode of the combat vehicle in the whole. The quantitative and qualitative criteria of fullness of fuel material burning in the engine are chosen as the basis for the evaluation of the reaching of the force-majeure mode. The “flat noise” of the efflux is chosen as the basis of this evaluation. This method ensures the construction of the stochastic structure of “flat noise” in the engine efflux and, in that way, confirms the possibility of technical implementation of the force-majeure mode. The rotor system further ensures not only the force-majeure formation, but also reaches the minimum noise of the combat vehicle at the change of its dislocation. The research results can be further used to optimize the design of exhaust systems, which will reduce emissions.

Summary

Introduction

After the appearance of increasingly perfected weapons, a single combat vehicle has become, in a definite sense, a sensitive target. This aspect isespecially acute in the conditions of long-range combat—at a distance of 3000 m or more, when the combat vehicle on a cross-country track of irregular complicated relief does not have the possibility to timely detect the enemy’s presence, on the one hand, and, at the same time, spends significant time on the collection, treatment and transition of the navigation information to the control system. The efficiency of the enemy’s defeat increases significantly by a skillful combination of two operations—fire maneuvering and movement maneuvering (along the line of the front and inside). With the implementation of force-majeure (French), when the combat vehicle movement is realized in a veryshort period of time and, at the same time, with maximal gradient an increase in the engine power [1]
