Abstract
The present invention provides an aircraft wing (10) having a main portion (20) with a trailing edge (20b) and a movable flaperon (22) hingedly secured at the trailing edge. A movable flaperon seal (40) is hingedly attached at its leading edge to the trailing edge of the main portion of the wing. Interconnecting structure is provided between the main portion of the wing and the flaperon seal. Such structure is operable to pivot the seal flap such that the opening between the trailing edge of the main wing portion (20b) and the leading edge of said movable flap (22a) on the upper surface is selectively closed by the movable flap at predetermined angular positions of the movable flap.
Claims14
An aircraft wing assembly comprising:
- (a) a main wing portion having a trailing edge;
- (b) a pivotal flaperon directly attached to said main wing portion;
- (c) a flaperon seal pivotally attached to said main wing portion;
- (d) control means for interconnecting said flaperon and said flaperon seal and for angularly positioning said flaperon seal relative to said flaperon as said flaperon is pivoted relative to said main wing portion, said control means comprising:
- (i) a rigid arm attached to said flaperon seal;
- (ii) a cam follower attached to said rigid arm;
- (iii) a cam surface for receiving said cam follower attached to said flaperon;
- and
- (e) actuation means for moving said flaperon relative to said main wing portion.
An aircraft wing comprising:
- (a) a main wing portion having a trailing edge,
- (b) a pivotal flaperon having a leading edge hingedly secured directly to the trailing edge of said main wing portion,
- (c) a flaperon seal pivotally attached to said main wing portion;
- and
- (d) control means interconnecting said flaperon and flaperon seal for pivoting said flaperon seal such that the gap between the trailing edge of said main portion and the leading edge of said movable flaperon on the upper surface is selectively closed by said movable flaperon seal at predetermined position angles for said movable flaperon, said control means comprising:
- (i) an arm extending from said flaperon seal with a cam follower attached thereto;
- and
- (ii) a cam surface on said movable flaperon portion for guiding said cam follower to effect the desired angular orientation of said flaperon seal.
In an aircraft wing having a main portion with a trailing edge and a movable flaperon hingedly secured at the trailing edge, a seal comprising:
- (a) a movable flaperon seal having a leading edge hinged for movement relative to the trailing edge of the main portion of the wing,
- (b) interconnecting structure comprising an arm extending from said flaperon seal with a cam follower attached thereto, and a cam surface on said movable flaperon for following said cam follower to effect the positioning of said flap seal, such structure being operable to pivot said seal flap such that the gap between the trailing edge of the main portion and the leading edge of said movable flap on the upper surface is selectively closed by said movable flap at predetermined angular positions for said movable flap.
