Tests of a conical-spherical body in a supersonic wind tunnel were carried out on a free oscillation installation along the pitch angle at a Mach number M = 1.75 and two moments of inertia of the body relative to the axis of rotation. For a body with a large moment of inertia, self-oscillations with the amplitude of ca. 10 deg were obtained. For the first time, the phenomenon of degeneration of self-oscillations for a body with a smaller moment of inertia has been discovered. An attempt was made to model the phenomenon using an ordinary linear differential equation of the first order

The effect of hydrostatic compression on the elastic and electronic properties of β-glycine crystals has been studied by quantum-chemical modeling. A relationship has been established between changes in the microscopic quantum pressure, macroscopic compressibility, and also the geometric and energy characteristics of hydrogen bonds that form the structure of β-glycine crystals before and after the transition to the high-pressure β’-phase.

BINP SB RAS together with RFNC-VNIITF carry out a research in the field of creating new sources of electromagnetic radiation in the THz range. Within the framework of this article, a project of the THz beam-plasma generator based on an electron beam generated by a linear induction accelerator is presented. The article provides generator scheme and describes the main elements of the electron beam formation system. In addition, the results of modeling the beam transport and its cross-section compression are presented. These calculations were performed under the current up to 1 kA and energy up to 1 MeV for the subsequent injection of the beam into the plasma section with plasma density up to 1015 –1016 cm–3. The article also contains the analysis of previous experimental studies results which are connected with the beam-plasma interaction for various beam and plasma parameters. Based on this analysis, a requirement for the ratio of the beam and plasma electron densities was formulated. This requirement should be satisfied for creation of the beam-plasma generator of EM radiation for the range of 0.1–1 THz with a pulse power of several MW.

A discrepancy between the energy input into the plasma and the energy lost through the measured loss channels is observed in the Gas Dynamic Trap (GDT): while 2-3 megawatts of power are captured by the plasma from the neutral beams, the observed energy losses do not exceed hundreds of kilowatts. In this study, a proposal was investigated that a part of the input energy is lost on the limiters of the GDT. The proposal was based on numerical modelling results that predict an existence near the limiter of a peak of power transferred to the plasma via fast ion drag. The experimental results showed that the energy losses on the limiter are too small to explain the energy balance discrepancy and further investigations of large loss channels are required.

In the wavelength range λ = 900–1200 nm, the spectral dependences of the refractive index n and extinction coefficient κ of a thin film, which is the heterostructure based on In0.2Ga0.8As/GaAs quantum wells, are found. The values of n and κ found at each point of the spectrum provide the minimum of the objective function, which is the sum of the module of the differences between the calculated reflection and transmission coefficients and the measured reflection and transmission coefficients of the sample grown on the GaAs substrate.

In a subsonic wind tunnel, the effect of slip and attack angles on the separation structure of the flow around the model of a trapezoidal flying wing was experimentally studied. In the course of this fundamental study, visualization patterns of a near-wall flow on the leeward side of the wing were obtained at the angles of attack of 0 and 18 degrees and oncoming flow velocity of 25 m/s. It was shown for the first time that gradual increase in slip angle of the wing leads to the restructuring of the flow, up to the disappearance of the local or global separation region on one of the consoles of the model. At the same time, on the second console, the separation is maintained. An increase in the angle of attack of the swept wing led to the development of a separation region: from a locally separated bubble to separation from the leading edge with a reverse flow and the formation of a pair of large-scale vortices. For the first time, singular points on the surface of the model for each mode have been found; by setting cone-shaped perturbation sources in these points one can achieve a significant improvement in the flow around the wing.

Detailed investigation of two-dimensional roughness element influence on the flow behind three-dimensional roughness element was carried out. For the first time studies were conducted on the windward side of the flying wing in the range of free-stream 7,2 – 20 m/s in the favourable gradient region behind roughness elements. Secondary instability mechanisms of disturbances leading to turbulence stage were investigated. It was shown that longitudinal structure forming behind three-dimensional roughness element grows downstream and has its trajectory slightly bend. The longitudinal structure consists of two stationary disturbances different in size. This can be explained by presence of cross flow and secondary disturbances leading to the transition. On the straight wing model, influence of the distributed suction on the stationary disturbance development was investigated and quantitatively determined. It was shown that suction is able to relaminarize the flow and eliminate the separation of the boundary layer.

In this work, it is shown that the dependence of the mass of conductive band electrons in a metal on their energy can be a reason of enhancement of the absorption of powerful laser radiation by the metal. To do this, a problem of response (current) of the electron placed in one-dimension periodic potential (lattice) to an electric field periodic in time (electromagnetic wave) is solved. The solution shows that for sufficiently large amplitude of the wave the dependence of the electron current on the wave amplitude becomes non-linear. Within a certain rangе of parameters, this dependence can be described by a simple formula that corresponds to the dependence of the electron mass on its energy. The formula was used for solving the problem of penetration of electromagnetic wave into a metal with the approach of modified Drude model. The non-linearity results in the enhancement of the wave absorption and generation of wave with frequencies close to those of plasma penetrating deep into the metal. The discussed effects manifest themselves in electric fields about. 1 V/Angstrom. The obtained results can be used in the interpretation of experiments data and in the creation of mathematical modeling of the interaction of powerful laser radiation with metal.
在这项工作中，表明金属中导电带电子的质量对其能量的依赖可能是金属对强激光辐射吸收增强的一个原因。为了做到这一点，解决了一维周期电位(晶格)中的电子对时间周期电场(电磁波)的响应(电流)问题。结果表明，当波幅足够大时，电子电流与波幅的关系变成非线性的。在一定的参数范围内，这种依赖关系可以用一个简单的公式来描述，该公式对应于电子质量对其能量的依赖关系。利用该公式，用修正的德鲁德模型求解了电磁波穿透金属的问题。非线性增强了对波的吸收，产生的波的频率接近于等离子体穿透金属的频率。所讨论的效应在电场中表现出来。1 V /埃。所得结果可用于解释实验数据和建立强激光辐射与金属相互作用的数学模型。
