Abstract

A convertiplane (1) is described, which comprises a fuselage (2) extending along a first axis (A), a pair of half-wings (3) projecting cantilevered from respective sides of the fuselage (2), a pair of nacelles (4) housing respective engines and operatively connected to the half-wings (3); and a pair of rotors (5) associated with the half-wings (3), rotatable around respective second axes (B) and tiltable so as to arrange the convertiplane (1) in an airplane configuration or in a helicopter configuration. Each half-wing (3) further comprises a wingbox (20) and an appendage (21) articulated on the wingbox (20) and selectively movable between a relative first neutral operating position taken when the convertiplane (1) is in the airplane configuration and in which it defines an extension of the wingbox (20) and a relative second position taken when the convertiplane (1) is in the helicopter configuration and in which it defines with the wingbox (20) a compartment (50) through which the air flow generated by the respective rotor (5) can pass. The convertiplane (1) comprises a closing system (60) configured to elastically preload each appendage (21) towards the respective first neutral operating position.
