Embodiment Construction

[0040] The following is attached Figure 1-5 The application is described in further detail.

[0041] The inventive idea of ​​the present application is that the wing structure needs at least three independent closed-loop deformation units to realize the gradual change of the camber of the mechanism. The essence of the smooth and continuous change of the wing camber is that the independent closed-loop units in series in the mechanism have gradually increasing deformation displacements in the same deformation direction. When the displacements of the three closed-loop units in the vertical deformation direction increase sequentially, the entire structure A smooth and gradual curvature can be formed. Therefore, in the design of the continuously variable camber wing structure, there must be a basic unit with amplified displacement between adjacent closed-loop units, so that the next closed-loop unit can obtain the enlarged deformation displacement in the same direction. By analo...

Abstract

The invention provides a complex hinge-containing continuously variable camber wing structure for a high-speed aircraft, the complex hinge-containing continuously variable camber wing structure comprises a closed-loop deformation unit, a displacement amplification mechanism and a driving mechanism, the closed-loop deformation unit is a closed-loop four-side structure, and every two adjacent sides of the closed-loop four-side structure are hinged; the closed-loop deformation unit comprises a fixed closed-loop unit, a tail closed-loop unit and at least one middle closed-loop unit located between the fixed closed-loop unit and the tail closed-loop unit, and the fixed edge of the fixed closed-loop deformation unit is fixed to the aircraft body. The driving device is used for driving the fixed closed-loop deformation unit to deform; the displacement amplification mechanism is connected between two adjacent closed-loop deformation units, the previous closed-loop deformation unit deforms and can drive the displacement amplification rod to move, and the displacement amplification rod enables the next closed-loop deformation unit to obtain deformation displacement amplified in the same direction. The wing structure has high camber adjusting capacity, and continuous and smooth adjustment of the camber of the mechanism can be achieved.

Description

technical field [0001] The application relates to a continuously variable camber wing structure with multiple hinges for high-speed aircraft, which belongs to the technical field of aircraft. Background technique [0002] A hypersonic aircraft refers to an aircraft that cruises in the atmosphere or across the atmosphere at a speed above Mach 5. It has the characteristics of fast flight speed, moderate altitude, strong maneuverability, and short reaction time.
