Reduction of aerodynamic resistance at an aircraft/glider uses a compressor to remove the boundary layer flow from the fuselage skin by suction, and pass the air mass to a fuel cell system to generate energy

摘要

To reduce the aerodynamic resistance of an aircraft (1), the boundary layer flow at the fuselage skin is removed by suction and the extracted air mass is passed to an on-board fuel cell system (5) to generate energy. The boundary layer flow is taken from the wings (2) or the rudder structure. A compressor extracts the boundary layer flow from the fuselage skin, by suction, and the compressor outlet is linked to the air supply (4) of the fuel cell system.
