Project summary

The problem of technical supply in industrial extreme situations (intensive ionizing radiation, radioactive wastes, dangerous physical and chemical factors, fires, damages of buildings and equipment) is complex and includes the following tasks:
a) elimination of accidental consequences;
b) maintenance of harmful and dangerous facilities in extreme conditions or local accidental situations;
c) elimination of harmful and dangerous facilities in extreme conditions.

This problem has two technical aspects:


1) development of complexes for several technological purposes, for example: explosive cutting any metal or non-metal structures, quick cutting orifices and hatches, etc.;
2) application of robotized means for technological complexes transportation and control.

Over 200 firms in the world are developing robotized equipment; they have good financial support and achieved significant results. International organization CRISME of industrial robot engineering is founded, whose program for movable robots development has a financing volume about 2,0 billion US dollars. First attempts to develop technological complexes with use of directed explosive energy were performed in Russia in 1991-94. However, they gave no practical result. First application of directed explosion was mentioned early 90-th in a report on disassembling methods for JPNDR experimental nuclear reactor in Japan. Directed explosion used widely for works after nuclear accident in the NPP Chernobyl showed its high efficiency for extreme conditions. Other applications of directed explosion are known: for putting out fires, for destroying damaged buildings and structures. Good results were also obtained for ruins removal after the earthquake in Armenia. In such situations delivery and installation of explosive charges is mortally dangerous for men. Application of remote controlled technological complexes using available robotized means should exclude risk of such extreme works.

We suppose to develop explosive cutting technologies for metal cylinders, sheets, profiled products, for concrete structures, as well as for explosive perforation. We are going to develop a technical project of a new remote controlled technological complex “Remote controlled pyrotechnical cutter” using cumulative charges as a cutting tool, which form directed impact influence on materials; to make a pilot specimen of this remote controlled complex.

A new subject of the project is that cumulative charges are purposed first for remote controlled equipment to be working in extreme conditions that may significantly decrease risk when working in such conditions. Application of means based on cumulative charges with significantly lower weight allows to extend widely a range of applied robotized equipment: 20 to 60 kg in comparison to other universal cutting equipment (air-plasma cutting machine: over 180 kg, contact-arc cutting machine: over 200kg). The technological complex with directed explosion has a low power consumption: AC 36-220V, to 1A.
