Problems solved by technology

[0005] The patent No. 200910017614.X introduces a two-way synchronous automatic flipping wing aircraft. The flapping of its ailerons is passively flipped relying on the force of the airflow on them, and the flapping is irregular and uncontrollable. Wing asymmetry, it is difficult to achieve actual flight

Embodiment Construction

[0033] combine Figure 1-Figure 17 The present invention is described further:

[0034]The double-joint bionic flapping-wing aircraft includes a fuselage beam 11, a flapping-wing drive device 10, a main-wing bar 13, an aileron bar 7, a main-wing reinforcing bar 6, a main-wing linkage bar 26, a main-wing joint 12, an aileron joint 8, and a fuselage skeleton 15 , main wing framework 9, aileron framework 1, empennage driving device 5, empennage vertical rudder 3, empennage horizontal rudder 4, power supply and control module 5. The flapping wing driving device 10 provides the power of the flapping wing, and transmits the power to the main wing lever 13 and the main wing linkage lever 26. The aileron lever 7 moves synchronously with the main wing under the action of the main wing linkage lever 26, and the characteristics of the up and down movement are similar to those of birds. Similarly, the main wing frame 9 and the aileron frame 1 are used to ensure that the cross-sectional s...

Abstract

The invention provides a bionic double-joint flapping wing air vehicle and belongs to the field of aerospace. The bionic double-joint flapping wing air vehicle comprises a fuselage, a flapping wing driving device, a main wing, an aileron, a main wing joint, an aileron joint, an empennage driving device and an empennage. The bionic double-joint flapping wing air vehicle is characterized in that the fuselage comprises a fuselage transverse beam and two fuselage frameworks, wherein the two same fuselage frameworks are arrayed in parallel and are fixedly connected with the fuselage transverse beam; the fuselage transverse beam penetrates through the centers of the fuselage frameworks. The flapping wing driving device is fixedly connected with the fuselage frameworks; the main wing is connected with the fuselage frameworks by the main wing joint; the main wing can rotate relatively around the fuselage frameworks by taking the main wing joint as a rotary axis. The aileron is connected with the main wing by the aileron joint; the aileron can rotate relatively around the main wing by taking the main wing joint and the aileron joint as rotary axes. The empennage driving device 5 is fixedly arranged at the rear end of the fuselage transverse beam and the empennage is connected with the empennage driving device. According to the double-joint bionic flapping wing air vehicle, left and right flapping wing devices are fully symmetrical and the flight stability is improved.

Description

technical field [0001] The invention relates to a bionic flapping-wing aircraft with double joints. The main wing and the aileron are driven by a connecting rod to realize a flapping action with a high degree of bionics. The flapping of the aileron is definite and regular, and belongs to the field of aerospace . Background technique [0002] Flapping wing flight is one of the best ways for animals to fly in nature. Compared with fixed-wing and propeller aircraft, flapping-wing aircraft has the advantages of high aerodynamic efficiency, large load, and easy take-off and landing, and can be used in manned transportation and unmanned aerial vehicles. [0003] Considering the potential use value and technological promotion of flapping-wing aircraft, developed countries such as Japan and the United States have attached great importance to it. In addition to the deficiencies encountered by fixed-wing and rotary-wing aircraft in performing missions and applications today, in orde...
