Problems solved by technology

[0003]Traditional winglets (wing tips) have low drag reduction efficiency in non-design states such as takeoff and climb. In recent years, a variant winglet ( Folding wingtip) concept, it can actively change its own geometric parameters and layout according to the flight state of the aircraft, which can not only improve the cruising performance of the aircraft, but also effectively improve the low-altitude and low-speed performance of the aircraft during take-off, landing, and climb stages, thereby further Optimizing Aircraft Fuel Economy

Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and technical solutions.

[0021] Such as Figure 1 to Figure 3 As shown, a wingtip turning mechanism for a modified wing includes a left rib 1, a right rib 2, a connecting structure 3, and a driving element 4, and the left rib 1 and the right rib 2 are fixedly connected to the connecting structure 3, and the driving The element 4 passes through the rib 1 and is fixedly connected with the rib 2. The connection structure 3 includes an elastic element 31, a support plate 32, and a U-shaped frame 33. The elastic element 31 is fixedly connected with the U-shaped frame 33. The support The plate 32 is rotatably connected with the U-shaped frame 33 .

[0022] Such as figure 1 As shown, the support plate and the ribs are hinged by means of a U-shaped frame, which neither restricts the turning movement of the mechanism, but also prevents the axial compr...

Abstract

The invention belongs to the technical field of aircraft wing variants, and discloses a wingtip turning mechanism for a morphing wing. The mechanism comprises a wing rib, an elastic element, a supportplate, a U-shaped frame and a driving element, and is characterized in that the driving element transmits tension to the wing rib to bend and deform the elastic element so as to realize turning motion of the mechanism. The mechanism can be regarded as a deformation unit, a deformation angle and a deformation area of the wingtip are increased by connecting two or more deformation units in series,and problems of poor surface continuity and poor overall air tightness of the wingtip deformation area are solved.

Description

technical field [0001] The invention belongs to the technical field of aircraft wing modification, and in particular relates to a wingtip turning mechanism for a modified wing. Background technique [0002] The morphing wing can actively change its shape according to the change of flight conditions to obtain the best aerodynamic performance, which greatly improves the mission adaptability of the aircraft, and has become one of the most promising technologies in future aircraft design. [0003] Traditional winglets (wing tips) have low drag reduction efficiency in non-design states such as takeoff and climb. In recent years, a concept of variant winglets (folding wingtips) has emerged, which can actively Changing its own geometric parameters and layout can not only improve the cruising performance of the aircraft, but also effectively improve the low-altitude and low-speed performance of the aircraft during take-off, landing, and climb stages, thereby further optimizing the f...
