摘要

The aircraft has a fluid duct system (26) for suction of a boundary layer and cleaning of fluid in endangered places of an outer skin of the aircraft. The duct system is connected to a pumping device that is driven, by cabin exhaust air, for production of desired low pressure for suction of the boundary layer though a stop valve (6). The pumping device is a jet pump (3), whose driving jets are generated by the exhaust air.
