HIGH-LIFT GENERATING DEVICE, WING, AND NOISE-REDUCTION DEVICE FOR HIGH-LIFT GENERATING DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a high-lift generating device which reduces noises caused when flaps are deployed and suppresses the degradation of aerodynamic characteristics when the flaps are retracted, and moreover, suppresses an increase in weight, and to provide a wing and a noise-reduction device of the high-lift generating device. PSOLUTION: The high-lift generator includes a flap 5 arranged in a deployable/retractable manner to a main wing, and a protrusion 6A-1 protruded smoothly in a direction away from the flap 5 in the vicinity of at least one end in the positive pressure surface PS of the flap 5.
