DEVICE FOR TESTING OF PYROTECHNICAL COMPOUND Russian patent published in 2000 - IPC

FIELD: investigation of burning conditions and check-up of the quality of pyrotechnical compound - condensed non-current-conducting systems producing current-conducting slags at burning. SUBSTANCE: device has a shell with pyrotechnical compound under test, ignition unit, electrodes, and the main and auxiliary channels of recording of electric signal. One of the electrodes is part of the shell end surface on the side of the ignition unit made of current-conducting material. The other two electrodes are made of wire, manufactured of the same material, have the same dimensions and located inside the shell symmetrically relative to the shell longitudinal axis and in parallel with it. The current-conducting part of the shell end surface on the side of the ignition unit and the first wire electrode are connected to the main recording channel of electric signal. Both wire electrodes are connected to the auxiliary recording channel of electric signal. EFFECT: enhanced trustworthiness of tests. 2 cl, 2 dwg
