Abstract
A method is described for the folding of a convertiplane with a fuselage having a first axis, a pair of wings and a pair of rotors arranged on respective mutually opposite sides of the respective wings; each rotor comprises a mast rotatable about a second axis and a plurality of blades; each wing comprises a first portion fixed with respect to the fuselage; a second tip portion opposite to the first portion; and a third intermediate portion, which is interposed between the associated first portion and second tip portion; the mast of each rotor is integrally tiltable with the second axis and associated second tip portion about a third axis transversal to the second axis and the fuselage so as to set said convertiplane between a helicopter configuration and an aeroplane configuration; the method comprises the steps i) of arranging the convertiplane in the helicopter configuration and ii) rotating a pair of assemblies of respective wings with respect to the fuselage and the associated first portion about respective fifth axes, so as to arrange the convertiplane in a stowage configuration.
