Aerodynamic component with a leading edge flap

摘要: An aerodynamic component such as a helicopter rotor blade has an flow profile, free end and mounting forming root for attachment to mast. A section between the leading edge trailing viewed in or chord direction. The is enclosed on its suction side pressure with respective skin. nose flap secured by bearing hinge. tilting angle adjustable piezo-drive elements arranged at least one pair actuator each flap. piezo-elements of are direction behind other body fixed point positioned pair. expansion contraction from piezo-element closer transmitted push rod. pronged pull-fork. rod pull-fork drive lever flap, whereby displacement pull fork causes adjustment push-pull action.
