Project summary

The aim of the project is to make specialists both in Russia and abroad familiar with the application of peaceful explosions, major experimental computational and theoretical techniques, principals and approaches.

Background.

Explosive technologies, i.e., the application of explosions in various branches of national economy have been playing a prominent role for a long time while addressing a variety of sophisticated engineering problems. The importance of explosive technologies has significantly increased in recent years when the disarmament process was initiated in the world.

Area of participants' expertise.

The majority of research results under consideration have been obtained by the team of the RFNC-VNIIEF's gas dynamic pision with the direct involvement of and headed by the author, namely, by the doctor of engineering sciences, the correspondent member of the Russian Academy for Rocket and Artillery sciences, academician S. A. Novikov.

Expected results.

The project implementation will result in the elaboration and compilation of the monograph '"Useful explosions" in the Russian and English languages. The monograph will present major characteristics of the dynamic strength for structural materials. The knowledge of this data is essential to predict the behavior of materials while using various methods for explosive pulse loading. The results of the research into the behavior of solid HE under the pulse loading (dynamic strength, shock-wave sensitivity) are presented. The data on the efficiency of applying shape charges for the explosive cutting and remote disassembling of damaged weapons, without detonating the primary HE charge, are summarized. Two novel singular explosive technologies are described, i.e., the technique using the rarefaction shock waves to fragment bulky steel structures, registered as an invention, and the reusable explosion-driven facilities, built around the explosive-driven pressure generator for the industry. The development results of the shock technique designed to compact diamond nanopowders by employing explosion-driven ballistic facilities are presented. The examples of applying the explosion-driven welding of bi-metals are given. The technique to fragment solid-alloy parts by using damage-proof containers is proposed.

The section dealing with the application of nuclear explosions for peaceful purposes in the areas of science and industry is of cognitive interest.

The book is intended for students of colleges and institutes, post-graduate students, engineers and technical personnel of enterprises and institutions involved in the development and application of explosive techniques.

The overall monograph, consisting of the introduction and 13 chapters with illustrations, covers 300 pages.

ISTC objectives.

The project will:

– provide the RFNC-VNIIEF's scientists and specialists, involved in the development of nuclear weapons, with the opportunity to redirect their skills toward peaceful activities by using the gained knowledge and experience for the elaboration of the monograph;


– allow the integration of the RFNC-VNIIEF's scientists and specialists into the international scientific community through the familiarization of Russian specialists' experience and the direct communication at scientific conferences.

Scope of Work.

The project implementation will involve the development of the monograph covering 300 pages and consisting of the introduction and 13 chapters with illustrations. The efforts milestones are as follows:

– Elaborating the monograph's layout.


– Preparing the monograph's manuscript.
– Preparing the electronic version for the monograph in the Russian and English languages.
– Developing the reporting documents.

The Role of Collaborator.

In compliance with the scope of activities to be performed within the framework of the project under consideration (see above), the following types of collaborative efforts are anticipated:

– information exchange during the course of the project implementation;


– experts' judgment of the monograph's materials;
– rendering assistance to the project participants in arranging the attendance of international meetings and workshops.

Technical approach and methodology.

The systematization and analysis of major novel explosion-driven techniques developed and introduced in recent years are assumed. The required computations substantiating the efficiency of the techniques applied will be performed.
