Поэтому синтез новых нитрозамещенных производных оксаазатетрациклододекана (оксаазаизовюрцитана) является перспективным направлением поиска перспективных нечувствительных высокоэнергетических материалов. При сборе твердых смешанных составов основной объем заполняется дисперсными кристаллами окислителя (перхлорат аммония, нитрат аммония и др.) и различными энергетическими добавками (октоген, гексоген, CL-20 и др.), а высокие концентрации занимают частицы металлов. В результате исследований были получены кристаллы циклических нитраминов типа CL-20 и октогена с включениями частиц оксида алюминия или железа (III) различного размера.

At the Institute for Problems of Chemical and Energy Technologies synthesized molecules that are promising candidates for a drug based on derivatives of hexaazatetracyclo dodecane. It has been shown that the use of Al nanoparticles as fuel in solid fuel can increase the specific impulse by 0.5-1%. The samples were pressed on the copper plate with a thickness of 1 mm, in the center of which there was a hole with a diameter of 3 mm.
COLLABORATION OF HIGHLY ACCURATE QUANTUM CHEMICAL CALCULATIONS AND THERMAL ANALYSIS TECHNIQUES IN THE STUDY OF THERMOCHEMISTRY. In the present contribution, we show two typical applications of quantum chemistry in combination with experience. First, we proposed the convenient and easy procedure to determine thermochemistry of EM, viz. the solid formation enthalpies.
2nd SESSION
In the present work, the combustion of single spherical models of particles-agglomerates from a mixture of aluminum and boron was experimentally investigated. For experimental studies, a test device was created, which includes a short chamber for ignition and initial combustion of solid fuel in a fast (subsonic) air flow and a long (up to 1 m) column. In the first series of experiments, the main operating regimes of the device (solid dots) were realized, corresponding to the conditions in the ramjet combustion chambers during the actual flight from M = 2 to M = 7 (colored area).
Combustion of the composition was studied in the reactor for combustion at atmospheric pressure. The formation of nitrides occurs in the second stage of combustion when the temperature in the combustion zone exceeds 1800-2000°С. The catalyst is used to initiate the chemical reaction of SHP163 in the same method as the hydrazine propellant and the hot gas produced by the chemical.
In this study, we focused on laser ignition, which has a long lifetime because there is no ignition object in the combustion chamber. Compared to solid fuels, the engine has a low cost of fuel components and a lack of explosives in the composition.
3rd SESSION
We placed a plug of MS crystals (5 and 10 cm long for NT and DNMS, respectively) secured with glass wool plugs (1 cm long) on both sides in the middle of the tube. For example, in the event of breakdown of TV, TV2, TVF, TVV, TGV series turbine generators whose container is filled with hydrogen, it is possible the formation of "hydrogen flame", i.e. in the course of a long-term work, the authors have stored a considerable experience in studies, design, development and production at critical objects of fire protection or different type of building constructions.
It has been proven that intumescent coatings, which are basically used in NPPs, can provide specific limits of fire resistance of structures only in the case of so-called "standard" fire and are not used in the mode of hydrocarbon fuel combustion. The cumulative jet, passing through several layers of barriers, partially loses continuity, partially loses energy breakthrough and interacts with the RF located in the pores of the ceramic material, which in this case is under pressure 10. Based on the received, we rightly assume that the higher temperature of heating into contact surface data, the jet of material flows intensively.

At the output of the spectrograph in the spectrum localization area, the cathode of the time-gated ICCD camera is placed, which allows signal detection in photon counting and charge accumulation modes. The Raman Lidar for the detection of chemical materials on the surface was tested in the laboratory room under standard conditions. For the experiments, several high-energy, low-volatility nitrogen-containing substances included in the database of Raman spectra were used.
The minimum detectable concentration of traces was determined in the process of detecting the traces with a predetermined surface density at a threshold signal-to-noise ratio of 2.

The influence of using different propellants and coolants, inserting different elements in CC and CU constructions, different materials in G G construction elements on the protagonist. According to the results obtained, the gas generator construction has been developed at FR&PC. This design makes it possible to ensure the necessary level of the main parameters with a relatively low mass of the article (4-5 kg).

The use of pyrotechnic compounds, i.e., thermite, has been proposed to reduce the risk of thermally stable deorbiting parts of LEO satellites falling off at the end of their life on Earth. Tarver developed the ignition and growth model, a homogeneous description of the explosive reaction rate, capable of improving the reliability of explosion calculations. According to its three phases aiP n‘, this model can be seen as describing the equation F = f (F , P ) in a pressure basis.
To perfect the tools of an anticumulative guard, knowledge of the parameters of the interaction of a cumulative flow with materials from a multicomponent barrier is very necessary. As materials for a barrier are considered: copper, steel, ceramics based on oxide of aluminum Al2O3 ceramics based on carbide of silicon SiC, a carbide of a pine wood B4C, nitride of silicon Si3N 4, nitride of a pine wood BN. Calculation results show that the contact site with the target fragment CS depends on the collision speed of 2000 to 8000 m/s implemented pressure from 47 to 362 GPa in the current material (Cu); from 44 to 271 GPa in ceramics; from 12 to 108 GPa - in the oxidizing environment.
Use a program that evaluates the calculation of the residual temperature Т *, which the substance reaches due to the passage of the shock front with amplitude Pi and subsequent unloading to the initial pressure. It should be noted that the pressure on the front shock waves in the cumulative flow and the materials of the middle boundary of the section reached very high values (from a few gigapascals to hundreds of gigapascals), depending on the shock velocity and the properties of the materials. The heating temperature of the medium depended on this parameter in the contact zone, which is reflected in the calculation of the results.
On the basis of receiving data, it is legitimate to consider that the temperature is heated in a contact zone, the more intensively the material cost of a stream is higher. Result calculations according to parameters of the cumulative current of the interaction fragment with barriers in a contact zone had thus made it possible to open the additional factors influencing the mechanism of penetrating cumulative current in multicomponent barriers. In particular, high temperatures in a contact zone reveal boiling metal flow exceeding the temperature, testified to the factor of possible vaporization of metal together with chemical interaction it with oxidizing medium of a barrier.
Of course, we should be this factor that has not been taken into account so far when designing anti-cumulative barriers with the aim of allowing a cumulative current to penetrate at a higher cost, and therefore the reduction in depth has been more than pervasive.
POSTER SESSION
In this work, based on the analysis of the equation of conservation of energy in the combustion chamber, is determined by the minimum value of the free volume, which ensures stable combustion of the grain, depending on the type of SRP and and . Over the past decade, large-scale re. The research conducted aimed to investigate the effect of acceleration (in the range of 0 to 700 g) directed along the normal to the burning surface on the burning rate of N-powder with the addition of aluminum particles with a radius of 1 to 100 pm in the pressure range from 20 to 100 atm.
Separation of the filler from the binder in the structure of calculated m o d e under tension. The remote detector reliably recorded the response to the presence of TNT and RDX in the 100th fingerprint, which corresponds to a surface density of explosive part.

Prospects for the further research and practical developments in the field of EEA and EES are associated with electro-explosive formation of new structural and phase states on the surface of metals and alloys using thermo-active components. Moreover, even in the developed countries there is a danger of hospital infections caused by resistant cultures of microorganisms [1].
The obtained results allow to estimate the absorption time after dust spraying in the environment containing harmful aerosol pollution. A metallographic analysis has revealed that the material has Mg2Si grains with distinct faces and an average size of 15 pm on the surface of the sample. In the case when the temperature changes significantly along the surface of the body, it is necessary to calculate the process of heat propagation in it together with the calculation of the flow field.
The resulting expression for the heat flux can be used as boundary conditions for the non-stationary equation for heat propagation in the body. In the first step, we have investigated the solubility of FTDO - DNP in each solvent in a molar ratio of 1:1. Thus, molecular complex furazan[3,4-e]tetrazine-4,6-dioxide-2,4-dinitro-2,4-diazapentane (1:1 amounts) was isolated, investigation of its crystal structure by X-ray diffraction method showed that the is fully consistent with published literature [7].
