Title
(EN) WINGLET AND WINGLET COVER ASSEMBLY
(FR) AILETTE DE BOUT D'AILE ET ENSEMBLE CAPOT D'AILETTE DE BOUT D'AILE
Abstract
(EN) A winglet (10) is disclosed, with first and second covers (20, 22), a front spar (24), a rear spar (26), and a mid spar (28) between the front spar (24) and the rear spar (26). Each spar is joined to the first cover (20) and to the second cover (22). The mid spar (28) has an I- shaped cross-section comprising a mid spar web (29), a first pair of mid spar caps (29a, 30a) joining the mid spar (28) to the first cover (20), and a second pair of mid spar caps (29b, 30b) joining the mid spar (28) to the second cover (22). The mid spar (28) has a length and the mid spar (28) curves along all or part of its length. A winglet cover assembly (100) is also disclosed, with a cover (20) and a spar (28) formed from fibre-reinforced composite material. The spar (28) has an l-shaped cross-section comprising a spar web (29), a first pair of spar caps (29a, 30a) joining the spar web (29) to the cover (20), and a second pair of spar caps (29b, 30b); and the cover (20) is bonded to the first pair of spar caps (29a, 30a).
(FR) La présente invention concerne une ailette de bout d'aile (10) dotée de premier et second capots (20, 22), d'un longeron avant (24), d'un longeron arrière (26), et d'un longeron central (28) entre le longeron avant (24) et le longeron arrière (26). Chaque longeron est raccordé au premier capot (20) et au second capot (22). Le longeron central (28) présente une section transversale en forme de I comprenant une âme de longeron central (29), une première paire de chapeaux de longeron central (29a, 30a) reliant le longeron central (28) au premier capot (20), et une seconde paire de chapeaux de longeron central (29b, 30b) reliant le longeron central (28) au second capot (22). Le longeron central (28) présente une longueur et le longeron central (28) s'incurve le long de tout ou partie de sa longueur. La présente invention concerne également un ensemble capot d'ailette de bout d'aile (100) doté d'un capot (20) et d'un longeron (28) constitué d'un matériau composite renforcé par des fibres. Le longeron (28) présente une section transversale en forme de l comprenant une âme de longeron (29), une première paire de chapeaux de longeron (29a, 30a) reliant l'âme de longeron (29) au capot (20), et une seconde paire de chapeaux de longeron (29b, 30b); et le capot (20) est lié à la première paire de chapeaux de longeron (29a, 30a).
