Claims (6)

1. Способ защиты топливных баков вертолета от термического воздействия тока молнии, включающий нанесение на поверхность топливного бака диэлектрического покрытия и электропроводящего поверхностного слоя, отличающийся тем, что на диэлектрическое покрытие наносят слои нетокопроводящей эмали, а затем на ее последний слой перед отверждениеи наносят напылением металлический порошок для образования электропроводящего поверхностного слоя.1. A method of protecting helicopter fuel tanks from the thermal effects of a lightning current, comprising applying a dielectric coating and an electrically conductive surface layer to the surface of the fuel tank, characterized in that layers of non-conductive enamel are applied to the dielectric coating, and then metal powder is sprayed onto its last layer before curing to form an electrically conductive surface layer. 2. Способ по п. 1, отличающийся тем, что напыление металлического порошка осуществляют при воздействии на топливный бак вибраций. 2. The method according to p. 1, characterized in that the spraying of the metal powder is carried out when exposed to vibrations on the fuel tank. 3. Способ по п. 1, отличающийся тем, что электропроводящий поверхностный слой выполнен из порошка никеля или другого вещества, имеющего низкое сопротивление электрическому току. 3. The method according to p. 1, characterized in that the conductive surface layer is made of nickel powder or another substance having a low resistance to electric current. 4. Способ по п. 1, отличающийся тем, что диэлектрическое покрытие с электропроводящим поверхностным слоем располагают на характерных для попадания молнии участках наружной поверхности топливного бака. 4. The method according to p. 1, characterized in that the dielectric coating with an electrically conductive surface layer is located on the areas of the outer surface of the fuel tank that are characteristic of lightning penetration. 5. Способ по п. 4, отличающийся тем, что для топливных баков вертолета Ми-8 диэлектрическое покрытие и электропроводящий поверхностный слой располагают на нижней части баков до высоты h= 0,35-0,45 Н, где Н - высота топливного бака, h - высота диэлектрического покрытия. 5. The method according to p. 4, characterized in that for the fuel tanks of the Mi-8 helicopter a dielectric coating and an electrically conductive surface layer are located on the lower part of the tanks to a height of h = 0.35-0.45 N, where N is the height of the fuel tank, h is the height of the dielectric coating. 6. Способ по п. 1, отличающийся тем, что по периметру электропроводящего слоя приклеивают плетеную сетчатую ленту из латунной проволоки для отвода тока молнии. 6. The method according to p. 1, characterized in that around the perimeter of the electrically conductive layer, a braided mesh tape of brass wire is glued to drain the lightning current.
