Abstract
490,151. Folding wings for aircraft. BAYERISCHE FLUGZEUGWERKE AKT.- GES. May 1, 1937, No. 12467. Convention date, May 8, 1936. [Class 4] Means for folding an aeroplane wing such that, when folded, the wing- chord is substantially vertical include a joint situated centrally of the wing profile and permitting rotation about two angularly-disposed axes and a brace rotatably connected at its ends to the wing and a point fixed relative to the fuselage. In one form, the wing 3 is connected to a centre-section 2 by an angled-pivot 7 journalled as shown on the wings. The wing 3 is further connected to the fuselage 1 by a strut 4. In a modification the pivot 5 is replaced by a balljoint and an obliquely arranged link is balljointed to the wing and centre section. In a further modification, the ball-joint is replaced by aT-shaped pivot, one arm being journalled in a cantilever wing. The pivot may be designed so that during folding the wing rises initially and subsequently moves through a position of stable equilibrium. A catch may be provided to hold the wings when folded and a shock-absorber may control the folding operation. Ailerons may be mounted on the foldable portion. The folding wing may, during folding, be moved away from the fixed portion of the wing.
