【 摘 要 】

The subject of investigation represents the designing data of explosion chamber and calorimetric device. The latter will allow the determination of the parameters of the detonation and energetic characteristics of low-sensitivity, emulsion and outdated explosives. Research methodology provides the study of standard explosives of published data only, which, at experimental investigations in the above-mentioned cases, do not agreed with the reality. The question problematical character is lied in the fact that the reduction of explosives sensitivity causes the increase of critical and limiting diameters of tested charge which, for its part, is associated with the increase of charge mass. Above-mentioned increases significantly the limiting values of designed dynamic loads, acting on the walls of explosion chamber and presents a serious hazard to the construction integrity. For problem, solving the new experimental explosion chamber together with calorimetric device was designed. In the chamber, for reduction of quasistatic pressures channels were designed the total area of their surfaces were calculated by theoretical methods together with other designed data of explosion chamber and calorimetric device. The procedure of the devise manufacturing is proceeding.
