Abstract: An airfoil for flow control is disclosed having an outer skin in contact with an ambient air flow, wherein the outer skin extends between a leading edge and a trailing edge with two opposite lateral sides, and surrounds an interior space. The outer skin comprises a porous section in the area of the leading edge, a pressure chamber arranged in the interior space and fluidly connected to the porous section, an air inlet fluidly connected to the pressure chamber, and an air outlet fluidly connected to the pressure chamber.

Abstract: An aircraft featuring: a fuselage with a fuselage section, an energy supply device, at least two supporting devices that are arranged on the fuselage section and serve for fastening the energy supply device, a mounting device for mounting an energy supply device on a structural component of an aircraft and an aircraft with a mounting device, as well as to a mounting device for mounting an energy supply device on a structural component of an aircraft and to an aircraft with a mounting device.

Abstract: In an embodiment, a fuel cell system for supplying emergency power to an aircraft, includes a fuel cell, a hydrogen tank, an oxygen tank, and a power distribution unit. This provides for an emergency power supply for aircraft that is reliable, independent of the outside air, and has low maintenance needs.

Abstract: An aircraft cooling system (10) comprises a cooling element (12), which comprises a housing (14), a cooling air inlet (18) formed in the housing (14) and a plurality of heat exchangers (32, 34, 36, 38), which are disposed on lateral surfaces (24, 26, 28, 30) of the housing (14) and through which cooling air supplied through the cooling air inlet (18) may flow. A cooling air supply channel (40, 40?) connects a cooling air supply opening (44, 44?) formed in a tail section of an aircraft to the cooling air inlet (18) of the cooling element (12). A cooling air outlet channel (46) connects the heat exchangers (32, 34, 36, 38) of the cooling element (12) to a cooling air discharge opening (50).
