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.
提出了一种将灭火剂输送到距离较远的火区的新方法——几何容器模型。运输的理念是基于投掷的机械过程。为此,物质(例如,灭火粉)被放置在一个特殊容器的固体外壳中。在运送到火灾地点后,容器应塌陷并释放出有助于灭火的物质。在已知的灭火剂远程投放方法中,使用带圆柱形容器的气枪。在输送过程中,气缸应绕其轴线旋转,以保证运动的稳定性。同时,对火炮炮膛内压缩气流分布的调节存在一定的困难。在一种新的运输方法中,使用了一个容器,它由两个球形容器组成,由一根杆连接(像哑铃一样)。哑铃的旋转和渐进运动是通过同时暴露于预先瞄准每个货物的爆炸脉冲来进行的。提出的将灭火剂装入哑铃状外壳的远程输送方法,需要对哑铃的元件设计进行研究。有必要将若干任务的解决方案与矛盾条件结合起来。首先,哑铃的设计应该坚固,能够承受爆发性疾病脉冲产生的起跑力。其次,设计应提供其交付到火区后的即时销毁。第三,哑铃的设计应该提供一种方便的技术来填充容器的灭火器。为了解决这个问题,建议使用阿基米德的多面体之一。由于两个球形罐哑铃的存在,两种灭火物质的单独交付的可能性使您能够开发一种新的灭火技术。其依据是,为了增加淬火效果,应在火区直接组合和混合一些化学药品。

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.
摘要本文在分析复变函数实部与虚部分离构成的平面等距网格参数方程的基础上,给出了平面正交曲线族隐式形成的解析描述。这个问题是由于这样一个事实,即平面等距网格,作为两个具有正方形单元格的正交坐标线族,用于保角映射,例如,当以最小的失真在曲面上绘制图像时。同时,平面平行线族也广泛应用于传热、电场、流体流动等几何建模中。这些几何图像之间存在联系,并通过具体的例子加以解释。等距网格参数方程的解析计算非常耗时,因此在符号代数Maple环境下进行。为此,建立了复变量任意初始函数与实虚部分离的等距网格参数方程推导交互模型软件。发现了平面等距网格参数方程的横坐标值和纵坐标值可以用显式曲面方程表示。对于复变量的指数函数幂的整数值,横坐标和纵坐标的值将用显式的代数曲面表示。横切面和纵切面的横截面经水平切面在水平面上的投影形成两族曲线,其方程只能隐式求得。以复变二次函数为例,证明了这两组直线是相互垂直的。本文给出了建立一组线的实际应用,用于围绕屏障以半圆形式流动的流体流动线的几何建模。

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.
维度空间,因此在其点的势上,具有辐射能量和产生该场的介质的形式。需要注意的是,产生物理场的能量来源可以是点的、扩展的(线性的)[2],也可以是面(平面)的形式。为了考虑这些参数,本文提出了由单点能量源在三维空间中形成的物理场中各点的实验得到的位势值,并将其与某条曲线进行插值,该曲线将确定距离源给定距离处任意点的位势,同时考虑到该场的无限远点。如果在从能量源到能量场点的距离与该距离对场点势的影响参数之间建立双曲关系的方案中添加考虑实验获得的数据的附加依赖项,则可以得到允许不限制从场点到能量源的距离的新方案。为了解决这个问题,从能量场点到点能量源的距离l将不像[3]那样沿着Ox轴,而是沿着Ol轴(图1)绘制,在Ox轴和Ol轴上的点之间建立一个额外的抛物线关系,从而可以考虑实验接收到的参数。

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
提出了一种将灭火剂投放到距离较远的火区的新方法的几何模型。交付理念是基于机械投掷操作。为此,一种物质(例如,灭火粉)被放置在一个硬壳-一个特殊的容器。容器通过启动装置送到火场后,必须释放出有助于灭火的物质。在已知的远程投放灭火剂的方法中,使用带圆柱形容器的气枪。在输送过程中,气缸必须绕其轴线旋转,以确保运动的稳定性。当圆筒经过炮口时,一个特殊的涡轮被用来解开它。在水轮机运行过程中,压缩空气流量分布的调节变得困难。此外,还需要监控喷枪气动部分的松紧度。新的运输方式使用了一个类似于运动哑铃的两个间隔的货物集装箱。哑铃运动的开始是由于爆炸脉冲以预先计算的方式同时作用于每个负载而进行的。结果是容器的旋转-平移运动。为了描述哑铃运动的动力学,确定了一个拉格朗日量,编制并求解了第二类拉格朗日微分方程组。给出了考虑空气阻力的哑铃质心轨迹建模实例。所提出的方法计划成为一种新的灭火技术的基础。一个利用两个哑炮的爆炸脉冲发射哑铃的新方案证明了这一点。得到的结果可以估计投掷所需的爆炸脉冲值,以及估计哑铃投掷距离的相应值

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","PeriodicalId":188754,"journal":{"name":"Modern problems of modeling","volume":"531 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124514888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
