INTRODUCTION TO DESIGN OF CLUSTER/CARGO WARHEAD FOR ARTILLERY ROCKETS

Aim of the Course:

The basic purpose of the course is extension of the knowledge necessary for design the warhead, containing submunitions of artillery rockets for multiple launcher rocket systems (MLRS). Main part of course program is the design of devices for separation, opening and scattering of cluster/cargo warhead for MLRS rockets. During the course several examples of the design of ensemble and elements of cluster warhead with the bomblets for artillery rocket will be performed. In addition, a method of testing of cluster/cargo warheads is explained in details.

Who should attend?

The course is intended for university students, engineers - researchers in the research institutions and engineers in the productions factories. It is advanced course it is assumed that attendees of course have good knowledge in mathematics, basic aerodynamics and ballistics and gas-dynamics).

Duration:

Duration is two or three weeks; 60 lectures (one lecture duration 45min), but other arrangement is possible.
