T-80 MBT sound dampening panels - Part 1
The goal of implementing sound-dampening panels on the T-80 MBT was to determine the possibility of mounting them in crewed compartments of the AFV, select materials that meet acoustic and operational requirements and evaluate their effectiveness in road conditions. A suitable design was to be developed by SPETSMASH (St. Petersburg) under the direction of V. M. Kirdey. Image 1: Sound-dampening panels installed in the turret fighting compartment Image 2: Unfolded sound-dampening panel for driver's position The dampening panels were placed in the following areas of the AFV and were composed of the following layers: The screens are comprised of various layers and materials in a certain order to achieve sound-dampening properties (the numeration of layers is counted outwards from the interior layer): Bottom of the hull between torsion bars: Povinol fabric, basalt fibre cardboard, knitting-stitching material, perforated fabric 500 (Cordura 500), PVC fabric, 2x knitted-needled ma...
