Abstract

1381476 Aircraft wing and flap assemblies HAWKER SIDDELEY AVIATION Ltd 30 Nov 1971 [30 Nov 1970] 56699/70 Heading B7G An aircraft wing and flap assembly includes a flap 5 which is supported in its rearward travel by a radius arm 12 pivotally connected at its upper end 13 to the flap structure and at its lower end to a hinge point 7 remotely positioned below the wing undersurface; and a rotary screw-shaft 8 mounted on the wing 3 and having a nut 16 thereon pivotally coupled to a bracket 14 under the nose of the flap 5A, the connection of the radius arm 13 to the flap 5 being rearward of the screw shaft nut 16 to provide clean flap breakaway on initiation of movement. The pivot point 7 is formed on a cantilever arm 6 rigidly secured to the wing 3. The flap has a main portion 5A to which the radius arm is pivoted and a tab portion 5B which is tilted with respect to the main portion 5A by a link 17 pivoted to the nut 16 and to a bracket 18 of the tab portion 5B. Cowls 19, 20 protect the flap moving mechanisms. A different arrangement of the link 17 is possible, Fig. 3A (not shown), and movement of the tab may be caused by engagement of a cam roller provided on the tab bracket in a cam slot formed in an extension of the upper part of the radius arm, Fig. 3 (not shown). The screw shaft may be arranged almost vertically instead of almost horizontally with consequent modification of the arrangement of the connection between the screw shaft nut and the flap, Fig. 4 (not shown).
