The article considers a number of main factors that determine the probability of damage to the elements of the engine and combat compartment of lightly armored vehicles under the influence of fragmentation munitions. Also, the technique of calculation of probability of defeat of an element by one fragment is given. As a result, the idea of a graph- analytical method for determining the probability of hitting an element by one fragment is presented, which is that the set of possible flight of the fragment to the element is divided into subsets by the number of walls of the engine and combat compartment of lightly armored vehicles. Then the required value of the probability of damage to the element by one fragment is determined.One of the main striking factors is the rapid flow of fragments that hit lightly armored vehicles, thus reducing the combat readiness of the unit. At present, the question of calculating the probability of damage to the elements of lightly armored vehicles of general military units is insufficiently studied.During the calculations of the graph-analytical method for determining the probability of damage to the elements of the engine and combat compartment of lightly armored vehicles, attention was focused on determining the required value of the probability of damage to the element by one fragment, which has not been proposed so far.The idea of a graph-analytical method for determining the probability of damage to an element by a single fragment is as follows. The whole set of directions of possible flight of the fragment to the element is divided into subsets by the number of walls of the engine and combat compartment of lightly armored vehicles. Within each subset, all directions are divided into parts, within each of which the value hijs is constant.The values of Sijs and hijs are determined for each part. The value of Sijs determines the probability of impact of the fragment from these directions, and the value of hijs - the probability of breaking the protective barrier.Then the required value of the probability of damage to the element by one fragment is determined. Thus, the use of a graphical-analytical method to determine the probability of damage to the elements of lightly armored vehicles of all-military units will increase the possibility of evacuation and restoration of weapons and military equipment after destruction by shrapnel munitions.And reducing the time for evacuation, speeding up the process of restoring damaged equipment in combat and increasing the intensity of the recovery system from recovery to use will increase the likelihood of using recovered equipment and, consequently, increase combat readiness.

The tasks to be solved are: to present the process of functioning of the system of armored weapons recovery and military equipment as a list of events and works that comprehensively reflect its essence and the interrelations between individual actions; to build a network graphical model of functioning of the armored weapons and military equipment recovery system of the assigned units; to analyze the critical path of network grapHhics; to identify critical work requiring closer scrutiny and identification of issues and risks that may impact the functioning of the whole recovery system, by analyzing and optimizing the network schedule make suggestions for improving the operation of the recovery armored weapons and military equipment system. General scientific and special methods of scientific knowledge are used. The following results are obtained. It was simulated the functioning of the armored weapons and military equipment recovery system of military units in performing their tasks by constructing a graphical network models critical path. Analysis network diagram allowed us to determine directions of improvement of functioning of system of recovery of armored weapons and military equipment under the conditions of limited material and nonmaterial resources and regular information updates. Conclusions. The network graphic model of the for restoring armored weapons and military equipment recovery of during combat operations it possible to present the entire scope of work, their logical and chronological relationship and to adjust plans taking into account the limited time and insufficient number and training of personnel. Analysis of the critical path of the network schedule makes it possible to conclude that if there are several battalions in the brigade, the repair of samples of armored weapons and military equipment with a labor intensity of more than 200 people / hour is on the critical path because the forces and means for the restoration of armored weapons and military equipment not enough in modern conditions. The network schedule for the recovery of armored weapons and military equipment with the functional distribution of the volume and list of works is optimal for the length of the critical path. The practical implementation of proposals to improve the functioning of the armored weapons and military equipment recovery system is possible by creating separate logistics units of the appropriate hierarchy levels and implementing an interspecific territorial system for providing military units

Analysis of wars and armed conflicts in recent years and the performance of tasks by military units (subunits) in a United Forces operation (anti-terrorist operation) confirms that the success of the troops (forces) in performing tasks will depend on the performance of the logistics system. The availability of military units with serviceable weapons and military equipment (WME) ensures the fulfillment of the mission and the advantage over the enemy. At the same time, the timeliness of providing military units (subunits) with serviceable weapons and military equipment depends on the efficiency of the logistics system, namely, on the recovery subsystem, which is its component. However, as studies have shown, there is currently insufficient sufficiency of the recovery system. All this is related to the definition of the composition of forces and means and the structure of the WME recovery system at different levels of the hierarchy. Therefore, in the article, it is considered that for the WME recovery system, the main parameter is the allowable time of WME recovery, differentiated by levels of complexity of tasks. Determination of this parameter for the basic variant of construction of WME recovery system is proposed using the average indicator of the intensity of the flow of possible volumes of tasks on the WME recovery. To determine the rational structure of WME recovery system and to calculate its main parameters the combined method of optimization of WME recovery system was used. Containing two stages: on the first - based on the requirements to the permissible terms of WME recovery system, the rational structure of the recovery system is defined, and on the second – using the method of statistical modeling, the parameters of the structure and composition of forces and means of the WME recovery system at each level of the hierarchy are defined.

Abstract The current maintenance system, preventively planned and applied to the military equipment according to the necessities, involves the rigorous execution of maintenance operations, which results in high costs and volume of work. These causes generally determine the formality of planned repairs and maintenance, with detrimental effects for the availability of vehicles. Moreover, the constructive-functional level of the current technical systems leads to the reorientation of adopting maintenance strategies that correspond to the availability level of the constructive kits to computerized diagnosis operations, such as the maintenance based on operational reliability. For some types of vehicles, the periodical technical inspection, besides allowing for regular traffic on public roads, can offer significant data for the managerial and technical implementation of the maintenance based on operational reliability within the military units. The paper aims at offering viable and efficient solutions for executing maintenance activities and for making vehicles available by turning to good account the data resulting from the technical diagnosis process, correlated with an optimal management of maintenance.

In the military units of the National Guard of Ukraine, a system for repairing automotive vehicles has been introduced, which provides for current, secondary and overhaul repairs. Maintenance of machines is carried out in order to eliminate malfunctions arising from the use of machines, and allows the replacement of individual units, including the main one. The average repair consists in the replacement or overhaul of not more than half of the main units. Overhaul restores the life of the machine and should be carried out at specialized enterprises of the Ministry of Defense of Ukraine or at other enterprises under contracts. Actually, in the military units of NGU, only current repairs are carried out. This is due to the high cost of overhaul and its low quality. Therefore, for the military units of the NGU, a diagnostic and recovery system for repairing automotive vehicles is proposed, including two types of repair: maintenance and restoration. The essence of maintenance repair consists in eliminating malfunctions, violations of adjustments during the operation of the machines according to the inspection, listening ? diagnostics with built-in and external diagnostic devices. Reconditioning repair consists in carrying out repair operations related to disassembling, troubleshooting, mechanical or other processing of component parts, assembling units, assemblies, testing them, and, if necessary, replacing them with new or repaired ones. Maintenance and repair repairs of automotive equipment are carried out only if there is a need for their implementation. It is proposed to establish ten parameters of the diagnostic and recovery system for the repair of automotive equipment at NGU and determine the life of the machine only before being discarding. The procedure for determining the number of machines that must be written off and get new ones to increase the non-reduced resource in each operation group is given.

There has been a war in Ukraine for 6 years. In this regard, the production of military equipment has increased significantly, including. armored vehicles. Serious requirements are imposed on any military equipment. This paper focuses on the reduction of the external noise of the Dozor-B armored vehicle both in terms of ecology and in terms of camouflage. The technical characteristics of the mentioned armored car and its main sources of noise are briefly discussed. It is concluded that the body emits a significant level of noise, and therefore it is important to reduce the total external noise of the armored car by reducing the noise emitted by the body of the latter. The dissertation work of Krutolapov V.Ye. was analyzed. "A method of improving the vibroacoustic characteristics of the car body using vibration damping materials." The dissertation deals with the method of measuring the amplitude-frequency characteristic of a plate with a damping coating, called "obst". We have pointed out the disadvantages developed by Krutolapov V.Ye. bituminous coated plates and suggested their solution. A method of reducing the level of external noise of armored vehicles by coating their housings with a multilayer damping coating is proposed. The algorithm of calculation of the mentioned covering is developed. The choice of the necessary materials is made on the basis of their acoustic properties, heat resistance and cost. The number of coating layers is calculated based on the required acoustic effect, cost and weight of the structure. The acoustic efficiency of the developed three-layer damping coating was calculated, as well as the estimation of the external noise reduction of the Dozor-B armored car for a number of speeds of the latter on the main cycle on the road due to the application of this coating.

Combat Readiness

A ship’s combat readiness is significantly dependent on the technical worthiness of basic ship equipment and mechanisms. Technical worthiness is determined by operation rates and depends on the condition of equipment. While using military equipment, one may expect the wear and tear of systems resulting from physical ageing, operation or combat damage. The restoration of ship’s technical efficiency is completed after returning to the harbour or during operations at sea. The tasks of restoring technical efficiency are performed in harbours and in naval bases by ashore elements of the repair system. During operations at sea a crew is able, to a limited extent, to carry out basic technical maintenance. The restoration of the technical worthiness and efficiency of ship equipment depends on appropriate logistic support.
