COMPREHENSIVE INVESTIGATION OF SEPARATING FLOWS IN THE AREA OF DISK AND CONE STABILIZERS OF STRIKERS LAUNCHED FROM BALLISTIC INSTALLATIONS

The distinctive features of separating fl ows occurring during the use of various ring shields and cone stabilizers to ensure a steady fl ight of rod strikers have been investigated. The investigations were carried out using numerical calculations, weight tests in a supersonic wind tunnel, and artillery-type ballistic tests. Data on the geometry of separation areas have been obtained, values of the aerodynamic coeffi cients have been identifi ed, and an assessment of the steadiness of structures′ fl ight has been made, which has been confi rmed by ballistic tests under real conditions. Analysis of the conducted mass experiments has shown the possibility of using the investigated aerodynamic devices for stabilizing high-aspect-ratio strikers at short distances under the conditions of high-level disturbances.
