Description

safer ignition compounds due to bigger concentration of the physical-chemical energy. This is easily to achieve in the circumstances of rnining and construction industries because the diameters of the sockets used (not greater than 75 mm) are considerably smaller than those of solid fiiel jet propulsion engines. It is possible to create such a flame spray by setting the ignition compound into a casing Where the thickness of the walls is considerably greater than the thickness of bottom (in the direction of the flame spray). The welding can be excluded by inserting with tension a casing with the ignition compound into the inner cylinder of the ignition unit's body. Between the body of the ignition unit and the inner cylinder there is a buffering cavity as well as in the prototype, which excludes the possibility of loss of integrity of the inner cylinder and the casing with the ignition compound. The fact that the ignition matter is situated into a separate constructive element (casing) which is not connected by welding with the others details of the ignition unit allows to automatize this most dangerous operation and decrease the part of manual labour in the production of the ignition unit. The loading of the ignition compound is carried out with a conductor on a vibrostand. The quantity of the simultaneously loaded with ignition compound casings is defined by the scales of the production. safer ignition compounds due to greater concentration of the physical-chemical energy.
