The paper considers scientific and methodological issues of military-economic analysis in the process of Armed Forces Russian Federation development, their technical equipment. The paper shows the ways to modify and use the methodology of decision assessment and decision-making process in the development of weapons from the point of the theory of utility.

An approach to the construction of forecasting models for the expected level of formation of necessary military professional competencies among students and cadets of educational institutions of the National Guard troops of the Russian Federation is considered. The basis of the approach is the representation of the formation of these competencies in the form of a set of processes for changing the values of the corresponding private indicators during training. The formal description of these processes is carried out in the form of a system of differential equations. To specify the parameters of the equations, a method of using the available empirical data is proposed. The proposed approach can be used in the construction of specific models and methods of decision support for managing the development of the military vocational training system.

The problem of formalized determination of vulnerable elements of military infrastructure object in planning anti-diversion measures is considered. Information on the tactics of action and typical composition of a sabotage-intelligence group is given. In conclusion, an example of calculation is given.

Modeling methods are considered to assess the feasibility and effectiveness of new scientific, technical and technological solutions in the creation of new weapons. When solving applied problems of system design (including assessing the feasibility and effectiveness of new technologies), it is proposed to use complex (joint) methods of expert and simulation modeling. A further development of the considered modeling methods is the introduction of artificial intelligence (hybrid modeling).

In this article are shortly described intended use, composition and level of incorporated connexity of modules of program-methodical package «Duplicate-Muzr». Here are described as prioritized requirements to the simulation modules based on the classification and generalization of functional reasonable opportunities of software special purpose. They presented update concepts and classifications which belong to simulation models. Analogues of acceptable requirement’s realization, which specify module’s image, are confirmed by example modules from various programs as well as ascertained particularities of their creation.

The prospect of increasing the commonality level of artillery complexes (ACs) by means
of projectiles fitted with a single-block integral propulsion system (SBIPS) is discussed.
Presented is an algorithm for defining geometric parameters of the common SBIPS. Also
presented are the evaluated characteristics of the new long-range projectiles. Ways to
further the commonality of Russian ACs’ ammunition equipment are proposed.

Presented are the results of theoretical and computational estimate of firing range extension for 2A36, 2A37-type guns by means of a new rocket-assisted projectile. The new projectile is fitted with a so-called single-block integral propulsion system, which has improved thrust and specific impulse compared to traditional projectile propulsion systems due to the use of atmospheric air in its workflow.

The problem of airframe high temperatures under aerodynamic heating is observed. Options replacing the titanium alloy VT20 with intermetallides based on titanium are proposed. A review of modern scientific and technical sources on the properties of alloys is carried out. The calculation of the temperature state of the aircraft body and numerical modeling of airframe loading are done. The advantages of the strength characteristics of the type of alloys and the prospects for their using as the airframe at high temperature levels of aircraft heating are noted.

Abstract: The article is devoted to three periods of development of indigenous multiple rocket launcher systems (MRLS), in which aerodynamic (M-13 projectiles), turbojet (M-14-OF projectiles) and again aerodynamic (9M22 projectiles) MRLS rocket projectiles (RPs) stabilizing methods were successively used on the trajectory. An important subsystem of the MRLS is the RPs launch subsystem — launch vehicle (LV), the requirements for which (in the history of the creation of the MRLS «Grad») directly affect the design of the stabilization units of the MRLS destruction subsystem — RPs. The stabilizing method is also determined by the required firing range and measures of dispersion. Sometimes it can be prescriptively specified for the use of already proven design schemes. And, of course, the competence of the parent company-developer leaves an imprint on the design of the projectile, the change of which can radically change the appearance of the sample.

In these paper oral presentations which were made in the 51-th 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.
