- The study presents preliminary experimental range tests of a system for testing protective shields for light armoured vehicles. The shields are designed against HE mines and IEDs up to 10 kg TNT. The system consists of the multiple-use portable range stand, a protected Armox 500T plate and a protective shield. The latter consists of the following main layers: PA11 aluminum, the SCACS hybrid laminate, ALPORAS aluminum foam, and the SCACS hybrid laminate. The layers are connected together with SOUDASEAL chemo-set glue. Overall dimensions of the test stand are ~ 800x800x180 mm, the protected plate has dimensions 650x650x5 mm, and a protective shield is of 450x450x76 mm dimensions. The system rests on a St3 steel plate stiffening the range subsoil. The range stand designed to be resistant up to 10 kg TNT blasts is composed of three appropriately shaped rigid frames connected with six high strength erection bolts. The explosive charge is suspended centrally at 400 mm distance from the top surface of the stand. Two range tests have been performed, i.e.: 1) the protected plate without a protective shield under 2 kg TNT blast shock wave, 2) the protected plate with the protective shield under 2 kg TNT blast shock wave. The effectiveness of the protective shield is assessed via comparing the maximum plastic deflection of the protected plate in both systems. The experimental results have been used to validate the FE model of the system.
