Abstract

Passenger evacuation in the event of a flight accident is often carried out using of inflatable life designs, and in the event of a fire it is important to save the air-tightness and efficiency of the life rafts. In defence of the membranous tissue materials, whereof inflatable life designs are manufacture, heat-reflecting enamel VE-72 is developed from influence of thermal radiation. Research has shown that the heat-reflecting coating of the VE-72 has high technical charac-teristics and also has proved the high efficiency of the heat-reflecting properties of the coating: the duration of the preset overpressure preservation of 20 kPa from exposure of an external heat current of 1,7 W/c2 is 15 minutes even with glue seams, which is 5 times higher than the requirements of the standard TSO-C69c and 3 times higher than the foreign equivalent of art. M-11673 (Air Cruisers Company, USA). Tests of materials on the preservation of leakage under the influence of radiant heat current were carr
