Vol 2, No 137 (2025): ИЗВЕСТИЯ РОССИЙСКОЙ АКАДЕМИИ РАКЕТНЫХ И АРТИЛЛЕРИЙСКИХ НАУК

The XXVIII All-Russian scientific and practical conference «Current problems of defense
and security» held in St. Petersburg in early April marked another stage in the activities of
the scientific community of the Russian defense industry, united under the leadership of the
Russian Academy of Rocket and Artillery Sciences. It is worth recalling this difficult path to
understand how Russia, thrown back in its development after the collapse of the USSR, was
now able to withstand the military might of the united West.

The article discusses the problems that may arise in the Russian economy during the implementation
of the energy transition on a global scale. A number of effective mechanisms have been proposed
as preventive measures. In particular, the introduction of a market for «green» certificates
according to the international standard I-REC, low-carbon modernization of the national fuel and
energy complex, and the implementation of the «carbon units» mechanism. It is also planned to
harmonize Russian carbon regulations with European standards.

This article continues the series of papers dedicated to research into providing a predictable
and energy-rational description of the behavior of groups of mobile objects (swarm of drones/
robots), based on classical physical principles. A mathematical model for describing the
behavior of such a group of objects is presented. Mathematical dependencies and simulation
results for a spatial problem are provided.

The article considers an approach to assessing the effectiveness of a damaging effect with
ready-made striking elements of various configurations of the warhead of a barrage munition.
When modeling high-speed processes, the finite element method was applied, which allowed
for a more accurate assessment of the area of damage to the barrier after interaction with the
damaging elements. The developed technique makes it possible to increase the effectiveness
of the use of barrage ammunition compared to the use of standard ready-made striking
elements in the form of a ball, without loss of operational reliability and basic tactical and
technical characteristics.

The analytical model of the network technological control system of the transport
communication network is presented as a subsystem of a highly dynamic communication
system in the form of a set of values describing input effects, external environment effects
and a set of internal characteristics. The functioning of the system is described as a sequential
change of the communication network states. The multi-level nature of the control system is
reflected in hierarchical connectivity matrices.

The article summarizes the basic technical requirements and development principles for
modern armaments and military equipment (AME) simulators, also presents a systematic
approach to creating simulators and analyzes the basic requirements for achieving maximum
efficiency in training personnel in preparation for combat missions.

A comparative analysis of ammunition of a simplified design is carried out according to the
power of their action, estimated by the reduced area of damage and the coordinate law of
damage. It is shown that the power of their action is at the level of standard products and they
can be used for mass production in order to eliminate the shortage of specialized means for
unmanned aerial vehicles.

The article considers ways to improve armored vehicle protection systems, taking into account
the experience of conducting a special military operation characterized by the widespread use
of unmanned aerial vehicles. The priority attention is paid to the possibility of joint use of
onboard electronic warfare stations and active protection systems.

The article discusses methods for modeling the combustion process of high-energy pasty
propellants for space propulsion engines. A physical picture of the process and a mathematical
apparatus for solving the modeling problem are presented. The analysis confirms the validity
of the model and its applicability for estimating composition solutions. Directions for model
improvement are outlined.

It is shown that a reasoned decision on the possibility of placing an anti-fragmentation screen
should be made separately for each modification of an explosion protection device depending
on the kinetic parameters of the fragmentation flow and the associated gas flow characteristic
of the detonation of explosive charges of standard mass containing damaging elements.

The authors article consider promising technologies for obtaining complex threads from
ultra-high molecular weight polyethylene (UHMWPE) and the possibility of its production
at chemical plants in the Russian Federation. The unique properties of UHMWPE in
combination with the peculiarities of the structural properties of textile materials created
by the technological capabilities of the equipment make it possible to expand the scope of
application of UHMWPE. Using the example of woven fabric, the possibility of designing a
given fabric structure for «soft» elements of personal protective equipment is shown.

The article deals with the former generals of the Lithuanian army: who honestly and flawlessly
performed their military duty in the ranks of the Red Army; who were a true example of
service to their Fatherland; who made a significant contribution to the Victory over Nazi
Germany and deserve the grateful memory of their descendants.

In this paper oral presentations which were made in the 52nd Annual Conference which is
dedicated to design problems of ammunition of different purposes and weapon are reviewed.
The Conference was held with the support of Russian Academy of Missile.
