Abstract

A braking force generation device has: a first mode in which a deflector and a blocker door are retracted with respect to a wing; a third mode in which, while the leading edge and the trailing edge of the deflector are separated from the wing and the blocker door is retracted, a second flow path is formed in which fluid flows via a fan from an opening on the leading edge side of the deflector to an opening on the trailing edge side; and a second mode in which, while the leading edge of the deflector is separated from the wing with the trailing edge being close to the wing and the blocker door is deployed, a first flow path is formed in which fluid flows via the fan from an opening on the blocker door side to the opening on the leading edge side of the deflector.

First claim

1 . A braking force generation device comprising:
a cross flow fan installed on a trailing edge side of a wing; a deflector installed above the cross flow fan and capable of being retracted or separated with respect to the wing; and a blocker door installed below the cross flow fan, rotating with one end side fixed to the wing as a center, and capable of being retracted or deployed with respect to the wing, wherein the braking force generation device has a first mode in which the deflector and the blocker door are retracted with respect to the wing, and a second mode in which, in a state where a leading edge of the deflector is separated from the wing with a trailing edge being close to the wing and the blocker door is deployed, a first flow path is formed on a lower surface side of the deflector and fluid flows from a rear to a front of the wing via the cross flow fan from an opening on a blocker door side to an opening on a leading edge side of the deflector in the first flow path.

2 . The braking force generation device according to claim 1 , wherein the braking force generation device further has a third mode in which, in a state where the leading edge and the trailing edge of the deflector are separated from the wing and the blocker door is retracted, a second flow path is formed on the lower surface side of the deflector and fluid flows from the front to the rear of the wing via the cross flow fan from an opening on the leading edge side of the deflector to an opening on a trailing edge side in the second flow path.

3 . The braking force generation device according to claim 1 , further comprising:
a drive unit; a first cam that is rotated by a driving force generated by the drive unit and to which one end side of a first link whose other end side is connected to the leading edge of the deflector is connected; and a second cam that is rotated by the driving force generated by the drive unit and to which one end side of a second link whose other end side is connected to the trailing edge of the deflector is connected.

4 . The braking force generation device according to claim 3 , further comprising:
a third cam that is rotated by the driving force generated by the drive unit and to which one end side of a third link whose other end side is connected to the blocker door is connected.

5 . A wing comprising:
the braking force generation device according to claim 1 .

6 . The wing according to claim 5 , further comprising:
a flow rate increasing device installed in front of the blocker door to supply fluid from a front to a rear.

7 . The wing according to claim 5 , further comprising:
a flow rate increasing device installed behind the blocker door to supply fluid from a front to a rear.

8 . The wing according to claim 5 , further comprising:
a high lift device installed behind the blocker door.

9 . A wing comprising:
a cross flow fan installed on a trailing edge side of the wing; a deflector installed above the cross flow fan and capable of being retracted or separated with respect to the wing; and a trailing edge flap installed below the cross flow fan, rotating with one end side fixed to the wing as a center, and capable of being retracted or deployed with respect to the wing, wherein the wing has a first mode in which the deflector is retracted with respect to the wing, and a second mode in which, in a state where a leading edge of the deflector is separated from the wing with a trailing edge being close to the wing and a tip of the trailing edge flap is moved frontward, a first flow path is formed on a lower surface side of the deflector and fluid flows from a rear to a front of the wing via the cross flow fan from an opening on a trailing edge flap side to an opening on a leading edge side of the deflector in the first flow path.

10 . The wing according to claim 9 , wherein the wing further has a third mode in which, in a state where the leading edge of the deflector is separated from the wing with the trailing edge being close to the wing, a second flow path is formed on the lower surface side of the deflector and fluid flows from the front to the rear of the wing via the cross flow fan from an opening on the leading edge side of the deflector to an opening on the trailing edge flap side in the second flow path.

11 . An aircraft comprising: the wing according to claim 5 .

12 . An aircraft comprising: the wing according to claim 9 .
