ARICRAFT WITH IMPROVED AERODYNAMIC PERFORMANCE
First Claim
1. An aircraft with improved aerodynamic performances, for maintaining direction stability and optimal aerodynamic behaviour with a medium-high incidence;
- said aircraft comprising a fuselage to which shaped wings are associated, at least one air intake and a nose with a tapered section, in which said aircraft comprises a control device of the vortex of the extension of the wing attaching edge to the root, shaped in order to symmetrize an explosion of vortexes generated by the edge with medium-high incidence, in which the ratio between the area of the edge and height is 2.35 m with a variable tolerance in a range from 100% and −
50% of the ratio, said control device of the vortex generated by the edge, cooperates with an offset tail, obtained by coupling of a vertical tail with the wings whose attaching edges penetrate trailing edges of each wing, in order to optimize said aerodynamic performances;
an equipment comprising at least one dissipating device of incident radar waves which can be applied in a removable way on at least one hot portion of the aircraft, by keeping aerodynamic features of the aircraft.

Abstract
An aircraft (10) with improved aerodynamic performances is adapted to keep the directional stability and a very good aerodynamic behaviour at medium-high incidence. The aircraft (10) includes a fuselage (12) to which shaped wings (18, 20) are associated, and a nose (52). The aircraft (10) also includes a vortex control device (72) of the extension of the leading edge of the wing at the root (LERX), shaped in order to symmetrize the bursting of the vortices generated by such LERX with a medium-high incidence. Said aircraft comprises removable equipment with at least one dissipation device of incident radar waves, on at least one hot portion of the aircraft.
