Wing structure and fairing device

摘要

A wing structure includes: a main wing that extends in a second direction intersecting a first direction as a fluid flow direction; and an auxiliary wing that is disposed so as to be separated from the main wing and faces the main wing at the front part side of the main wing, wherein a wing chord length of the auxiliary wing is shorter than a wing chord length of the main wing. A fluid contacts the auxiliary wing which is formed at the front part side of the main wing, the fluid is guided between the auxiliary wing and the main wing, and the fluid is compressed when passing between the auxiliary wing and the main wing, thereby appropriately forming a fluid compression process region on the surface of the main wing and increasing an acting force.

主权项

1. A fairing device that is provided in a vehicle, the fairing device comprising:
a main wing that protrudes in a second direction intersecting a first direction as the front-rear direction of the vehicle, the main wing comprising: a contraction flow forming portion that corresponds to a front part side of the main wing; and an expansion flow forming portion that is formed so as to be continuous with a rear side of the contraction flow forming portion; and an auxiliary wing that is disposed so as to be separated from the main wing and that faces the main wing at a front part side of the main wing, wherein a wing chord length of the auxiliary wing is shorter than a wing chord length of the main wing, wherein a gap between a front edge of the auxiliary wing and the main wing is wider than a gap between a rear edge of the auxiliary wing and the main wing, and wherein the rear edge of the auxiliary wing is formed in front of the expansion flow forming portion of the main wing in the first direction, wherein a curvature of a curved surface of the auxiliary wing directly facing the main wing is larger than a curvature of a curved surface of the main wing directly facing the auxiliary wing.
