Kurzfassung
Wind tunnel and flight tests have clearly demonstrated the potential of hybrid laminar flow control (HLFC) for drag reduction. Additional weight and costs of the suction system reduce the efficiency of the HLFC technology. Within the EC funded ALTTA programme a drastically simplified suction system has been proposed. Characteristic of this system is one single suction duct, the leading edge box itself, a double sheet suction surface with suction velocity control by orifices in the inner sheet and a constant speed suction pump directly with the leading edge box. The system is optimised for the design conditions of the aircraft at cruise. Investigations at design and off-design conditions reveal that the simplified system would operate as required within sufficient ranges of all parameters investigated.
