Abstract

Топливный бак ЛА, расположенный вдоль фюзеляжа, снабженный перегородками, разделяющими полость бака на отсеки и последним по выработке расходным отсеком, расположенным в нижней части бака, сообщенном с магистралью подачи топлива в двигатель и магистралями перелива топлива между отсеками в виде изогнутых трубопроводов, отличающийся тем, что в расходном отсеке установлено подпружиненное капиллярное заборное устройство с проницаемыми стенками из мелкоячеистых сеток, внутренняя полость которого соединена через сильфон с магистралью подачи топлива к двигателю, расходный отсек расположен с зазорами по отношению к наружной и внутренней обечайкам бака, расходный отсек выполнен в виде автономной герметичной емкости с двумя днищами в виде кольцевых секторов, соединенных двумя криволинейными и двумя плоскими поверхностями, и оборудован тремя оснащенными инерционными массами переливными клапанами, один из которых расположен в верхней части сечения отсека бака, предшествующего расходному, и сообщен с расходным отсеком двумя переливными магистралями, а два других на его плоских правой и левой поверхностях.A fuel tank of an aircraft located along the fuselage, equipped with baffles dividing the tank cavity into compartments and the last consumable compartment located at the bottom of the tank, connected to the fuel supply line to the engine and the fuel overflow lines between the compartments in the form of curved pipelines, characterized in that a spring-loaded capillary intake device with permeable walls of fine-mesh meshes is installed in the consumable compartment, the inner cavity of which is connected through a bellows to the main fuel to the engine, the consumable compartment is located with gaps in relation to the outer and inner shells of the tank, the consumable compartment is made in the form of an autonomous sealed container with two bottoms in the form of annular sectors connected by two curved and two flat surfaces, and is equipped with three overflow equipped with inertial masses valves, one of which is located in the upper part of the section of the tank compartment preceding the supply, and is connected to the supply compartment by two overflow lines, and the other two on its side their right and left surfaces.
