Description

лью предотвращени  проникновени  выбросных газов из одного канала в другой, каждый стык составных частей перегородок выполнен в виде вход щих один в другой четырехгранного обтекател  с углом между боковыми верхними гран ми, не превышающими 25°, и V-образного элемента, расположенного параллельно нижним гран м обтекател .In order to prevent the penetration of exhaust gases from one channel to another, each junction of the component parts of the partitions is made as a tetrahedral flap entering one another with an angle between the side upper edges not exceeding 25 ° and a V-shaped element parallel to the bottom edges fairing.
