Abstract: A convertiplane (1, 1', 1 '') is described that comprises a fuselage (2), having a first longitudinal axis (A), with a nose (12) and a tail portion (13); a pair of wings (3) arranged on respective opposite sides of said fuselage (2), carrying respective rotors (5); a pair of engines (4) operatively connected to respective said rotors (5); at least one first lifting surface (19, 16) arranged on said tail portion (13); and a pair of canards (14) arranged on said nose (12) of said fuselage (2) and defining respective second lifting surfaces adapted to generate a third 11ft/negative lift value; each rotor (5) comprising a mast (9) rotatable about a second axis (B) and about an relative third axis (E) transversal to said second axis (B) and with respect to the fuselage (2), so as to set said convertiplane (1, 1', 1'') between a helicopter configuration and an aeroplane configuration; each second axis (B), in use, being transversal to the first axis (A) of said convertiplane (1, 1', 1'') in said helicopter configuration and being parallel to said first axis (A) in said aeroplane configuration.

Abstract: A helicopter (1) is described comprising a fuselage (2) elongated along a first axis (X) and extending between a nose (6) and a tail boom (7); a tailplane (9) with a pair of first aerodynamic surfaces (11) elongated along a second axis (Y); the first and second axis (X, Y) define a first plane (Q); the helicopter (1) comprises a pair of elements (20) transversal to the first aerodynamic surfaces (11); and a pair of second aerodynamic surfaces (21) generating respective second aerodynamic forces, connected to first elements (20), and facing and spaced from respective first aerodynamic surfaces (11); each second aerodynamic surface (21) comprises one first root end (80) connected to the respective said element (20), a second free end (81) spaced from said tail boom (7), a first leading edge (55), a first trailing edge (56) opposite to said first leading edge (55), a first chord (C1) at said first root end (80) and a second chord (C2) at said second free end (81) parallel to said first axis (X); the first and the second chord (C1, C2) define a second plane (R) tilted with respect to said first plane (Q).
