For a premature breakdown of a wing vortex pair +/-.GAMMA.M behind an aircraft in flight (1) comprising a symmetry plane (7), two wings (3), a fuselage (2) and a horizontal tail plane (HTP) (4), the wing vortex pair +/-.GAMMA.M being generated in the area of the tips of the wings (3), having a first

For a premature breakdown of a wing vortex pair +/-.GAMMA.M behind an aircraft in flight (1) comprising a symmetry plane (7), two wings (3), a fuselage (2) and a horizontal tail plane (HTP) (4), the wing vortex pair +/-.GAMMA.M being generated in the area of the tips of the wings (3), having a first spin direction and descending behind the aircraft, an interfering vortex pair -/+.GAMMA.P, which is generated between the fuselage (2) and the tips of the wings (3) without merging already in the near field behind the wing (3) with the wing vortex pair +/-.GAMMA.M and which has a second spin direction that is opposed to the first spin direction, is retained behind the aircraft (1) in an altitude range of the wing vortices of the wing vortex pair +/-.GAMMA.M by adjusting to suitable values the relative circulation and the relative span of the interfering vortex pairs -/+.GAMMA.P, each related to the wing vortex pair +/-.GAMMA.M. The interfering vortex pair -/+.GAMMA.P includes portions of a fuselage vortex pair -/+.GAMMA.F, which is generated in the junction area of the wings (3) to the fuselage (2), and a tail plane vortex pair -/+.GAMMA.H, which is generated in the area of the wing tips (5) of the horizontal tail plane (4).

An aircraft comprisinga symmetry plane, two wings, a fuselage, a horizontal tail plane (HTP) and means for a premature breakdown of a wing vortex pair +/-.GAMMA.M, which is generated at the aircraft in the area of the wing tips, has a first spin direction with regard to said symmetry plane and de

1. An aircraft comprisinga symmetry plane, two wings, a fuselage, a horizontal tail plane (HTP) and means for a premature breakdown of a wing vortex pair +/-.GAMMA.M, which is generated at the aircraft in the area of the wing tips, has a first spin direction with regard to said symmetry plane and descends behind the aircraft, said means for a premature breakdown adjusting an interfering vortex pair -/+.GAMMA.P, which is generated between the fuselage andf the wings tips without merging with the wing vortex pair already in the near field behind the wings, has a second spin direction with regard to said symmetry plane that is opposed to the first spin direction and includes portions of a fuselage vortex pair -/+.GAMMA.F, which is generated by the wing-fuselage junction, and of a tail plane vortex pair -/+.GAMMA.H, which is generated in the area of the wing tips (5) of the horizontal tail plane (4), to suitable values regarding its circulation .GAMMA.M and the relative span of the interfering vortex pair, each related to the wing vortex pair, in order to retain the interfering vortex pair -/+.GAMMA.P behind the aircraft in an altitude range that is the same as an altitude range of the descending wing vortices of the wing vortex pair.
