초록

A high-lift device suppresses the occurrence of aerodynamic noise while minimizing an increase in airframe weight. The device includes a slat main body disposed to be able to extend from and retract into a main wing, and a concave part formed on the slat main body at a location facing the main wing and able to accommodate at least a part of a leading edge of the main wing. The device also includes an airflow control part disposed at an area in the concave part facing an upper surface of the main wing, that is accommodated between the main wing and the co...

1. A high-lift device comprising: a slat main body that is disposed so as to be able to extend from and retract into a main wing;a concave part that is formed on the slat main body at a location that faces the main wing, so as to be able to accommodate at least a part of a leading edge of the main wing; anda lower-surface plate that is a plate member extending along an extended line of a lower surface of the slat main body toward the main wing from an edge line at which the lower surface of the slat main body and the concave part meet when the slat main ...
