Abstract
Топливная система самолета, содержащая фюзеляжный бак с сигнализатором уровня и насосом подкачки, и фюзеляжный расходный бак с заправочным штуцером и насосом на магистрали перекачки, соединенной с дополнительным подвесным баком через содержащую обратный клапан линию заправки и трубопровод, конец которого, обращенный в расходный бак, перекрыт нормально-закрытым гидроуправляемым краном, а также трубопровод сжатого воздуха для вытеснения топлива из дополнительного подвесного бака и сигнализатор окончания его заправки, подключенный к питаемому от наземного источника тока приводу отсечного клапана, управляемого в соединительной линии, связывающей магистраль перекачки с рабочей камерой гидроуправляемого крана, установленного на обращенном в расходный бак конец этой магистрали, и насосом подкачки, отличающаяся тем, что, с целью обеспечения централизованной заправки дополнительных подвесных баков, трубопровод сжатого воздуха оборудован нормально-открытым трехходовым отсечным клапаном, в нормально-закрытом сливном канале которого, соединенном с расходным баком, установлен сигнализатор окончания заправки, а на участке соединительной линии между местом подключения командной линии трехходового отсечного клапана и рабочей камерой крана перекрытия магистрали перекачки установлен обратный клапан.The aircraft’s fuel system containing a fuselage tank with a level indicator and a booster pump and a fuselage fuel tank with a filling nozzle and a pump on a transfer line connected to an additional outboard tank through a return valve containing a refueling line and a pipeline whose end facing the feed tank is blocked a normally closed hydraulically controlled valve, as well as a compressed air pipeline for displacing fuel from an additional outboard tank and an indicator of the end of its refueling, connected to a cut-off valve driven from a ground source of current, controlled in a connecting line connecting the pumping line with a working chamber of a hydraulically controlled crane installed on the end of this line facing the supply tank, and a booster pump, characterized in that in order to provide centralized refueling of additional suspended tanks , the compressed air pipeline is equipped with a normally open three-way shut-off valve, in the normally-closed discharge channel of which is connected to the supply tank, It is connected with the signaling indicator of the end of refueling, and a check valve is installed at the section of the connecting line between the connection point of the command line of the three-way shut-off valve and the working chamber of the transfer line shut-off valve.
