Abstract
Official abstract text for this publication.
A high-lift device includes a flap body which is provided at a rear portion of a main wing which generates a lift for the air vehicle such that the flap body is deployed with respect to the main wing and stowed in the main wing and extends along a wingspan direction of the main wing; and a gap increasing section provided at an end portion of the flap body in an extending direction of the flap body, to increase a gap between the rear portion of the main wing and a front portion of the flap body in a state in which the flap body is deployed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A high-lift device of an air vehicle, the high-lift device comprising: a flap body which is provided at a rear portion of a main wing of the air vehicle such that the flap body is deployed with respect to the main wing and stowed in the main wing and extends along a wingspan direction of the main wing, wherein the flap body includes a tip end portion which is an end portion in an extending direction of the flap body, and a body portion which is a portion other than the tip end portion; and a gap section provided in front of a leading edge portion of the tip end portion and vertically penetrating the flap body, the leading edge portion of the tip end portion being located rearward relative to a leading edge portion of the body portion, and a chord direction dimension of the tip end portion being set smaller than a chord direction dimension of the body portion, to increase a gap between the rear portion of the main wing and a front portion of the tip end portion of the flap body in such a manner that the gap is larger than a space between the rear portion of the main wing and the front portion of the body portion in a state in which the flap body is deployed, the gap section provided so that air flowing along a lower surface of the main wing travels through the gap toward an upper surface of the flap body to weaken a swirling vortex from a lower surface of the flap body to an upper surface of the flap body, at the tip end portion of the flap body, wherein the gap section is open on a tip end portion side of the flap body.
