The proposed geometric container model for a new way to deliver a fire extinguishing agent into a fire zone located at a considerable distance. The shipping idea is based on a mechanical process of throwing. For this, the substance (for example, the fire extinguishing powder) is placed in a solid shell a special container. After delivery to the place of fire, the container should be collapsed and released a substance that will assist when steaming a fire. In the known method of remote delivery of the fire extinguishing agent, a pneumatic gun with a cylindrical container is used. In the process of delivery, the cylinder should rotate around its axis to ensure the stability of the movement. At the same time, the difficulty of regulating the distribution of compressed air flows in the dule of cannons. In a new delivery method, a container is used, which consists of two spherical tanks connected by a rod (like dumbbells). The initiation of the rotational and progressive movement dumbbells is carried out by simultaneously exposure to explosive pulses aimed at each cargo in advance. The proposed method of remote delivery of a fire extinguishing agent, packed into the shell of a dumbbell-like form, requires studies of the design of the elements of the dumbbells. It is necessary to combine solutions of several tasks with contradictory conditions. First, the design of the dumbbells should be strong and withstand the starting force created by explosive pulses of sickness. Secondly, the design should provide its instant destruction after delivery to the fire zone. And, thirdly, the design of the dumbbells should provide a convenient technology of filling the containers with fire extinguishes. To solve this problem, it is proposed to use one of the multifaceted bodies of Archimedes. The possibility of separate delivery of two fire extinguishing substances due to the presence of two spherical tanks dumbbells allows you to develop a new fire extinguishing technology. It is based on the fact that in order to increase the effect of quenching, some chemicals should be combined and mixed directly in the fire zone.

Abstract. The article reveals an analytical description of the formation of families of orthogonal flat curved lines in the implicit form based on the analysis of the parametric equation of a flat isometric grid constructed by separating the real and imaginary parts of the function of a complex variable. This problem is due to the fact that flat isometric grids, as two families of orthogonal coordinate lines with square cells, are used in conformal mappings, for example, when drawing images on curved surfaces with the least distortion. At the same time, families of flat parallel lines are widely used in geometric modeling of heat transfer, electric fields, fluid flow, etc. There is a connection between these geometric images, which is explained by specific examples. Analytical calculations of deriving the parametric equation of an isometric grid are quite time-consuming, so they are performed in the environment of symbolic algebra Maple. For this purpose, the corresponding software of the interactive model of derivation of parametric equations of isometric grids for any initial function of a complex variable with the subsequent separation of its real and imaginary parts was created. It was found that the values of the abscissa and ordinates of the parametric equation of a flat isometric grid can be represented as explicit surface equations. For integer values of the power of the exponential function of the complex variable, the values of the abscissa and the ordinate will be represented by algebraic surfaces in the explicit form. The projections of the cross sections of the abscissa and ordinate surfaces by horizontal cutting planes on the horizontal plane form two families of curved lines, the equations of which can be obtained only implicitly. By the example of the quadratic function of a complex variable, it is proved that these families of lines are mutually perpendicular. The practical application of building a family of lines for geometric modeling of fluid flow lines that flow around the barrier in the form of a semicircle is shown.

dimensional space, and therefore on the potentials of its points, has the form of radiated energy and the medium in which this field arises. It should be noted that the sources of energy that create the physical field can be point, extended (linear) [2], as well as in the form of surfaces (planes). To take these parameters into account, this article proposes the experimentally obtained potential values of individual points of a physical field formed in three-dimensional space by a single point source of energy, interpolating with a certain curve that will determine the potential of an arbitrary point at a given distance from the source, taking into account the infinitely distant points of this field. If you add an additional dependence that takes into account the experimentally obtained data to the scheme that establishes a hyperbolic relationship between the distance from the energy source to the energy field point and the parameter of the influence of this distance on the field point potential, you can get a new scheme that allows not limiting distances from field points to the energy source. To solve the problem, the distance l from the point of the energy field to the point energy source will be plotted not along the axis Ox, as it was in [3], but along the axis Ol (Fig. 1), establishing an additional parabolic relationship between the points of the axes Ox and Ol, which allows to consider experimentally received parameters.

A geometric model of a new method of delivering a fire extinguishing agent to a fire zone located at a considerable distance is proposed. The delivery idea is based on a mechanical throwing operation. For this, a substance (for example, a fire extinguishing powder) is placed in a hard shell - a special container. After being delivered to the fire site by means of a starting device, the container must release the substance, which will help extinguish the fire. In the known method for the remote delivery of a fire extinguishing agent, an air gun with a cylindrical container is used. During delivery, the cylinder must rotate around its axis to ensure stability of movement. A special turbine is used to untwist the cylinder as it passes by the muzzle of the cannon. During the operation of the turbine, it becomes difficult to regulate the distribution of compressed air flows. In addition, you need to monitor the tightness of the pneumatic part of the gun. The new delivery method uses a two spaced cargo container similar to a sports dumbbell. The initiation of the dumbbell movement is carried out due to the simultaneous action of explosive impulses directed at each of its loads in a pre-calculated manner. The result is a rotational-translational movement of the container. To describe the dynamics of the dumbbell movement, a Lagrangian was determined, and a system of Lagrange differential equations of the second kind was compiled and solved. The examples of modeling the trajectories of the centers of mass of the dumbbell weights with allowance for air resistance are given. The proposed method is planned to be the basis for a new fire extinguishing technology. This is evidenced by a new scheme for launching a dumbbell using explosive impulses of charges from two squibs. The results obtained make it possible to estimate the values of explosive impulses necessary for throwing, as well as to estimate the corresponding values of the dumbbell delivery distances
