There is described an airfoil combination for aircraft turbofan, designed to save fuel in aircraft operation, which is composed by two wings (5) and two supports (6) articulated or not, for each of the wings (5). These two wings (5) are located inside the turbofan, internally to the outer fairing (3) of the turbofan and externally to the other components of the turbofan. In one of the embodiments, the two wings may have high-lifting devices, such as flaps. The two wings use the “blown” air at great speed by the fan (1) to generate a pre-determined liftin...
1. An airfoil combination for a turbofan, the turbofan comprising: a fan,a stator,an outer fairing receiving the fan and the stator therein, andan inner fairing,the airfoil combination comprising at least two cambered wings disposed inside the turbofan such that each cambered wing is positioned outside the inner fairing and inside the outer fairing, each cambered wing including an upper wing surface that is more convex than a lower wing surface and positioned within the turbofan so as to generate a pre-determined lift when a fluid is passed thereover. 2....
