Description
Summary:This paper presents a new revolutionary design in commercial aircraft: the conven-tional vertical and horizontal tails are not present as generally known, and their contri-bution to the manoeuvering of the aircraft, namely the presence of the rudder and theelevators, is achieved by locating them at the wingtips and in the canard, respectively.Substituting the horizontal tail with the canard, the possibility of dividing the fuel be-tween the wing (where it is located conventionally) and the canard allows the pilot tochange the center of gravity during the ight with more freedom, while the eect of theelevators continues present. Locating the vertical stabilizers at the wingtips combinesthe eect of the vertical stabilizer and the winglet all in one, with the corresponding lostof weight. In this sense, the aerodynamic, stability and aeroelastic characteristics of anaircraft such as the one described have been analyzed using dierent modules belongingto CEASIOM program, and the results are very encouraging, showing that it is reallyfeasible to change the current concept of the commercial aircraft without penalizing theperformance.
