Reva G. A method of account of cylindrical reflectors of explosive waves for suppression of wood fires

The investigation object is the phenomenon of reflection of rays from the bent surfaces. The aim is to develop the theoretical base for calculation of optical characteristics of cylindrical reflectors. The geometry modeling, reflection method, and elasticity theory methods are the investigation instruments and devices. The theoretical basis of the method of geometry modeling of the objects of the reflection systems with the application of the MapleV programme is the obtained theoretical result. The algorithms of calculation of reflecting systems which provide the operation of the developed reflectors are created and put into practice. It's the practical result of the investigations. The thesis solves the science and applied problem of calculation of blast waves cylindrical sinusoidal reflectors used during the forest fires extinguishing. The problem is theoretically generalized and its new solution is given. The method of calculation of optical characteristics of sinusoidal cylindrical reflecto rs obtained through the elastic bending of the rectangular metal sheet is developed. On this basis the algorithm of modeling of the motion of the reflected rays and plotting of the blast waves fronts with the possibility to define their efficiency by the way of calculation of the reflected fronts waves surface area is made up. The results of the investigations could be used at different subdivisions of forestry of the Ukraine and at the Main Board of the State of the Fire Prevention of the Home Affairs Ministry of the Ukraine.
