Refraction has a strong influence on the accuracy parameters of the range-finding tract of laser tracking locators and the process of directing a narrow laser beam onto the object. High requirements for locators (the error of measuring the range to a few dozen centimeters) lead to the need to take refraction into account for making corrections to the measurements. Significant distortion of the signal leads not only to the phenomenon of static refraction, but also dynamic. To reduce the error of distance measurements it is advisable to use methods to compensate for the effect of static refraction or to take it into account and use the correction coefficients. The article shows that the most effective solution to the problem of refraction in the presence of a dynamic component is also the use of parallel laser probing of the atmosphere, but it must be carried out at two different wavelengths. In this case, the main method of calculating the correction factors is the dispersion method, which makes it possible to reduce the relative measurement error to 106. The use of laser methods for controlling atmospheric parameters, including two-wave and two-frequency ones, was described by us and experimentally investigated at the Chauda, ​​Feodosiya, and the Republic of Crimea fires on YAG: Nb3 + IZ-25 lasers and continuous lasers . The obtained atmospheric data on the LT-5Z laser were used to create a mobile laser-television locator for external-trajectory measurements of the descent of the aerial systems "Kafa +" and were installed both on the ground and on an air balloon. The flight trajectories of balloons and the descent of cargo parachute systems were studied.

An important role in the safety of the car's movement is played by the state of the operated tires. If the tire pressure decreases, the deflection increases. There is a flattening of the tire, which increases the bearing surface. The article presents the development of tire pressure monitoring systems. When using the tire, there is always the possibility of a puncture. Often this happens far from the car-care center and in this case, an urgent repair of the tire is required. A solution of this problem is presented with the help of a viscous substance or sealant. Also, the article describes the design of airless tires, which are not afraid of punctures.

The paper is devoted by studying of the correctness of the antenna pattern adaptive control problem in a randomly inhomogeneous medium. We use spectral methods for the solving the Helmholtz equation with variable parameters in the frozen medium approximation. We have proved the correctness of the problem of a given antenna pattern forming in a randomly inhomogeneous medium for the measured distribution of the complex wave amplitude in the plane of receivers in the first time. The possibility of using an antenna with a synthesized aperture for adaptive correction of the antenna pattern for maximization of communication channel capacity is substantiated. We use the refractive index model as the sum of the deterministic and random components in numerical modeling. The sampling intervals were chosen in accordance with the sampling theorem. The analytic expressions with given parameters were used as a model of the law of the antenna array operation. The results of numerical simulation confirmed that, in the first approximation, the problem of the antenna pattern controlling of a transmitter with a synthesized aperture based on the distribution of the complex wave amplitude measured in the plane of receivers is correct. It allows to create a system of adaptive antenna pattern correction for maximization of communication channel capacity.

The method of determining the speed of a bus before its overturning is considered. According to statistical studies, it was found that rollover of buses is a fairly common type of traffic accidents (road accidents). However, in this kind of accident, a large number of casualties and even deaths are recorded. In such cases, the investigator-investigator must identify the culprit in the accident, as a rule, it can be a master for the production of vehicles on the line, if the cause is a bus malfunction. In addition, it can be drivers of other cars or pedestrians. The driver of the bus, who took the wrong actions in the current dangerous situation, can also be guilty. The most common cause of an accident is the driver violating the speed limit. Therefore, the investigator-investigator must determine how fast the bus moved before tipping over. For this, there is a standard method for determining it. Based on the received speed value, it is concluded whether the driver violated or did not violate the established speed regime. However, this technique will give excessive values ​​of speed, for example, if the driver has made a maneuver "rearrangement", known as the elk test. Thus the bus, moving on an arc in the beginning in the right, and then to the left with the resolved speed, has risk to overturn. This is due to the impact of the alternating centrifugal force, as well as the additional forces acting on the bus bodies, due to the compression-expansion of the suspension springs. The article defines the speed of the bus before the overturning, at the time of the maneuver "rearrangement".

The present cultivators of the soil have a negligible width and depth of loosening is mainly up to 0.6 m. When the number of racks is significantly reduced completeness of loosening, increases the mass of the gun and increase traction resistance. In addition, the possibility of loosening soil to a greater depth is limited. There are rippers with surround deformers. They are inclined relative to each other vertical knife rack, rigidly connected to each other in the lower part with shingles made V-shaped with the apex directed upwards. In this architecture, the system deformers there is a need for analysis to determine the tensile strength in a first approximation: as much as possible to lengthen the elements of the blade without loss of strength and significant changes in their geometric characteristics of the flat cross-section. Reviewed the formulation of the calculation of the strength of the isotropic sloping steel plates of finite dimensions, a polygonal profile with rigidly clamped opposite edges of constant cross section, equal stiffness, as an element of deformers of the chisel type surround. Shows the justification of the selected geometric characteristics of the broken plate. Presents a preliminary finite element modeling using the software - computing complex Structure CAD (SCAD), considering static and dynamic loads. In the formulation of the numerical calculation primarily pursued the goal of establishing the adequacy of a solid model of the stress – strain state of a polygonal sloping steel plates of constant cross section with rigid pinched at the edges. It is established that the threat is a reduction in the actual thickness of the plate more than 1/3 of the project, which leads to failure of the individual piece of details. With little loss of thickness plots of displacements is characteristic reflects a valid value.
