(FR) Avion convertible
Abstract
(EN) There is described a convertiplane (1) comprising: a pair of semi-wings (3); at least two rotors (4) which may rotate about relative first axes (B) and tilt about relative second axes (C) together with first axis (B) with respect to semi-wings (3) between a helicopter mode and an aeroplane mode; first axis (B) being, in use, transversal to a longitudinal direction (A) of convertiplane (1) in helicopter mode, and being, in use, substantially parallel to longitudinal direction (A) in aeroplane mode; convertiplane (1) further comprises at least two through openings (8) within which said rotor (4) may tilt, when said convertiplane (1) moves, in use, between said helicopter and said aeroplane mode.
