Embodiment Construction

[0032] Below in conjunction with accompanying drawing, technical scheme of the present invention is further described as follows:

[0033] see Figure 1 to Figure 4 As shown, an aileron rotating and retractable flapping wing device of the present invention specifically includes: aileron rotating and retractable flapping wing wings and corresponding drive devices, wherein

[0034] (1) flapping wing

[0035] According to the direction of the wingspan, the wing is divided into two parts, the main wing and the aileron. The part close to the wing root and with a larger area is the main wing, and the part of the wing spanning to the outer edge is the aileron. The main support and movement tasks of the wing are undertaken by its leading edge skeleton, and the specific airfoil and the secondary skeleton of the airfoil can be selected according to actual needs. The main wing leading edge frame 7 and the aileron leading edge frame 13 are connected by a hinge, and the two can take the ...

Abstract

The invention relates to an aileron rotary folding and unfolding type flapping wing device, which includes aileron rotary folding and unfolding type flapping wings and a related drive device, wherein the wings are divided into main wings and ailerons along the wingspan direction, exterior edges of the main wings and exterior edges of the ailerons which are connected via butt hinge can relatively rotate on the wings plane with the butt hinge as an axis, and the aileron plane can be folded under the main wings plane, the drive device comprises a main wings drive device and an aileron drive device which are driven to be connected via a main drive shaft, the main wings drive device is positioned in the head section, and composed of two symmetrical crank rocker mechanisms which respectively drive the left wing and the right wing, and the aileron drive device is positioned in the middle-rear portion of the wings chordwise direction. The aileron rotary folding and unfolding type flapping wing device employs a bevel gear pair to realize rotation shaft changes, thereby multi-degree-of-freedom motion can be driven by single power, approximately saving one main drive shaft and related motors, and greatly reducing weight.

Description

1. Technical field [0001] The invention relates to an aileron rotating and retractable flapping wing device, in particular to a flapping wing airfoil and a driving device thereof which rely on the aileron rotating and retracting to change the wing area and increase lift, and belongs to the technical field of flapping wing aircraft. 2. Background technology [0002] Flapping-wing flight can take off in situ or in a small field, and lift, hover and propel are realized only by flapping wings. It has strong air maneuverability, high flight aerodynamic efficiency and low energy consumption. Therefore, the research on flapping-wing aircraft has great prospects and value. . However, flapping wing research is still immature in all aspects and needs to be developed. [0003] A single-degree-of-freedom flapping simple wing produces little lift and poor flight effects. To increase lift and improve load capacity, it is necessary to achieve multi-degree-of-freedom flapping wings similar...
