L'élément de blocage (H) est disposé dans le second conduit d'air (A5) de manière à diviser le second conduit d'air (A5) en un premier conduit d'air secondaire (A51) et un second conduit d'air secondaire (A52) qui sont espacés sur les côtés gauche et droit. Une zone de confluence est formée sur le côté sous le vent de l'élément de blocage (H) et la zone de confluence est reliée au premier conduit d'air secondaire (A51) et au second conduit d'air secondaire (A52). De l'air s'écoulant à travers le premier conduit d'air secondaire (A51) et le second conduit d'air secondaire (A52) converge dans la zone de confluence, puis s'écoule vers l'avant hors de la seconde sortie d'air (A22) dans la direction de l'élément de blocage (H).
