Abstract:
Pyrotechnic devices based on linear-shaped charges are widely used in rocket and space technology for stage separation and detachment of structural elements. The design of these systems involves a number of complex engineering tasks, one of which is determining the penetration depth of the cumulative jet into an obstacle of variable thickness. This complexity is due to local structural reinforcements in the form of ribs, fittings for operational elements, or deviations resulting from various technological factors. Among these factors are thermal stresses and deformations caused by the welding

Abstract:
The problem of electric pulse heating of a medium by the heater made of metal foil with an ideal thermal contact with the medium is solved. The solution is obtained in the form of rapidly converging series for ohmic heating power, which is given as an arbitrary function of time. Using the obtained solution, a dimensionless criterion is introduced for quasi-homogeneous heating of the heater up to a melting point with intensive heat transfer to environment. It is shown that with a fixed heating duration, the criterion value depends weakly on the type of a heating power function, which allows ign

Abstract:
An explosive bolt is a simple, highly reliable, and efficient pyrotechnic release device widely used in spacecraft and rocket launchers. High shock transient response is generated during the separation of a release device, which tends to damage the nearby micromechanism and hardware. The purpose of this article is to predict the shock response of an explosive bolt. In this paper, the separation process of a piston-type explosive bolt is simulated by using a hydrocode named AUTODYN and the influence of the charge amount on separation time, separation speed, and separation shock is analyzed.

Abstract:
In this study, a finite element model of a pressure cartridge-type pin puller is used to simulate the actuation process and predict the actuation shock using the deflagration equation of state and the fluid-structure coupling algorithm of the MSC/Dytran. The established model is validated by comparing the simulation results with the experimental results for pressure and actuation shocks. Based on the established finite element model, the contribution of the four shock sources to the actuation shock is quantitatively decoupled by changing the state of the pin puller. The results demonstrate tha

Abstract:
Для предупреждения и ликвидации опасных ледяных заторов в русле рек в настоящее время чаще всего применяется взрывной способ, реже авиационное бомбометание, минометно-артиллерийский обстрел, а также ледокольный метод. В статье описан опыт борьбы с заторами на затороопасных участках рек с применением эмульсионного взрывчатого вещества (ЭВВ) заводского производства марки НПГМ-П-II-М диаметром 60 мм, изготовленного по ТУ 20.51.11-016-37945333-2017, применяемого в качестве основного заряда для взрывания ледяных покровов.

Abstract:
Известен способ изготовления взрывчатого состава из невзрывчатых материалов для отбойки блочного декоративного камня путем смешивания перхлората калия (ПХК) с катализаторами разложения оксидов металлов, а в качестве горючего дизельное топливо (ДТ) или нитрометан (НМ) [1]. Невзрывчатые материалы: ПХК с катализаторами разложения и горючими компонентами смешивают на предприятии и снаряжают в пластиковые трубки, концы которых герметично закрывают пробками. Такие трубчатые заряды перевозят на места проведения взрывных работ.
