Abstract

An opening portion of a vent member is prevented from being blocked, and thus ventilation is reliably performed. A plurality of opening portions (40A, 40B) are formed in a single vent stringer (20), and thus even in a case where one of the opening portions (40A, 40B) is blocked, ventilation is secured by the other opening portion. At this time, since the opening portions (40A, 40B) are formed in surfaces different from each other in the vent stringer (20), a possibility that both the opening portions (40A, 40B) may be simultaneously blocked is less.

Claims

1. A vent member that is formed along an inner surface of a wing panel having an outer surface forming an outer surface of a wing and the inner surface facing an inside of the wing and is continuous in a longitudinal direction of the wing panel,

wherein a plurality of opening portions are formed in the vent member.

2. The vent member according to claim 1, wherein the plurality of opening portions are formed in surfaces different from each other in the vent member.

3. The vent member according to claim 1, comprising:

a pair of ribs which is formed integrally with the wing panel on the inner surface of the wing panel and is continuous in the longitudinal direction of the wing panel; and

a cover provided so as to close a space between tip portions of the pair of ribs.

4. The vent member according to claim 3, wherein at least one of the opening portions is provided in the cover facing the inner surface of the wing panel.

5. The vent member according to claim 4, wherein the opening portion is formed so as to be an opening end in an end portion of the cover and is formed such that a cross-sectional area of the cover on both sides of the opening portion is gradually reduced toward a terminus of the cover.

6. The vent member according to claim 5, further comprising;

an end plate provided in proximity to the terminus of the cover so as to close the space between the tip portions of the pair of ribs.

7. The vent member according to claim 3, wherein the ribs are formed by being cut out from the same metal matrix as the wing panel.

8. A wing panel that has an outer surface forming an outer surface of a wing and an inner surface facing an inside of the wing, comprising:

the vent member according to claim 1,

wherein the vent member includes

a pair of ribs which is formed integrally with the wing panel on the inner surface of the wing panel and is continuous in a longitudinal direction of the wing panel; and

a cover provided so as to close a space between tip portions of the pair of ribs.

9. The wing panel according to claim 8, wherein the plurality of opening portions are formed in surfaces different from each other in the vent member.

10. A main wing for an aircraft comprising:

a wing panel having an outer surface forming an outer surface of a wing, and an inner surface facing an inside of the wing; and

the vent member according to claim 1.
