Embodiment Construction

[0028] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0029] like figure 1 As shown, a miniature double flapping wing aircraft of the present invention takes the direction of the arrow in the figure as the front, and is controlled by two completely identical flapping wing systems, an intermediate connection structure 6, an attitude control steering gear 7, and a wing root position. The organization consists of 8. Each flapping wing system includes a reduction gear set 1, a flapping angle amplification mechanism 2, a hollow cup motor 3, a base 4, and flapping wings 5.

[0030] like figure 2 As shown, the reduction gear set 1 includes a main shaft gear 101 , a double-layer gear 102 and a bull gear 103 . The main shaft gear 101 is installed on the output shaft of the hollow cup motor, the large gear 103 and the double-layer gear 102 are installed in the middle mounting hole of the base 4, and the upper ...

Abstract

The invention discloses a miniature double flapping-wing aircraft, which comprises an intermediate connecting structure, an attitude control servo, a wing root position control mechanism and two completely identical flapping-wing systems. The miniature double-flapping-wing aircraft of the present invention further enhances the lift generation by means of the "opening-closing" mechanism of the wings; by changing the motor speed to affect the flapping frequency of the front and rear two pairs of wings, the two pairs of wings generate front and rear asymmetric lift, and then produce pitch control Moment: through an attitude control steering gear to control the wing root position control mechanism to change the position of the two sets of wing root rods, change the tension of the flapping wing membrane, cause the left and right wings to generate different lift forces, and generate roll control torque. In addition to using one steering gear to control two sets of wing roots, the present invention simplifies the control mechanism, reduces control difficulty, realizes weight reduction and saves resources, and also uses the "open-close" high-lift mechanism to realize aerodynamic lift.

Description

technical field [0001] The invention relates to the field of micro-aircraft, in particular to a miniature double flapping-wing aircraft. Background technique [0002] With the continuous innovation of aircraft design concepts and the great progress of microelectronics technology at the end of the last century, micro air vehicles were proposed and developed rapidly. With the characteristics of small size, light weight and strong maneuverability, micro air vehicles are suitable for reconnaissance, exploration and rescue assistance in complex environments, and have broad application prospects. As an important branch of micro-aircraft, the bionic flapping-wing micro-aircraft gradually began to appear with the development of bionics design. The flapping-wing micro-aircraft relies on the reciprocating flapping of the flapping wings to generate lift, and generates control torque through the fine control of the flapping-wing flapping process, which can maintain high aerodynamic eff...
