Abstract
The convertible aircraft with tilting rotors comprises two fixed wings with zero sweep on which an inter-connecting shaft is substantially rectilinear and parallel with the pivot axis but offset from this axis, substantially perpendicular to a longitudinal axis of symmetry of the aircraft, the center of gravity of which, in helicopter mode, is substantially in a vertical plane passing through the pivot axis and, in aeroplane mode, is substantially contained in or is in proximity to another vertical plane passing through the straight line of the aerodynamic centers of the wings.
