Novel butterfly-like flapping wing air vehicle

Abstract

The invention provides a novel butterfly-like flapping wing air vehicle which comprises a main trunk framework, a power mechanism, a transmission mechanism, a steering mechanism, wings, a power supplysystem and a flight control system. The power mechanism is arranged at the front end of the main trunk framework; the transmission mechanism is in transmission connection with the power mechanism; the wings comprise a left wing and a right wing which are symmetrically distributed on two sides of the main trunk framework and are connected with the transmission mechanism; the power mechanism is used for driving the left wing and the right wing to do flapping wing motion through the transmission mechanism; the steering mechanism is arranged at the back end of the main trunk framework; the powersupply system is connected to the back end of the steering mechanism and is electrically connected with the flight control system; the flight control system is fixed onto the main trunk framework; andthe power mechanism and the steering mechanism are electrically connected with the flight control system. According to the novel butterfly-like flapping wing air vehicle provided by the invention, adouble-wing symmetry driven flapping wing structure is realized, and the air vehicle can fly forwards, steer and pitch through controlling the rotating speed of the power mechanism and a swinging angle of the steering mechanism.

technical field [0001] The invention relates to the technical field of aircraft, in particular to a novel butterfly-like flapping-wing aircraft. Background technique [0002] The flapping wing aircraft refers to the aircraft whose wings can flutter up and down.

Due to the current theoretical research on the flapping-wing flight method is still insufficient, and the manufacturing process is highly complicated. Most of the flapping-wing aircraft can not reach the goal of miniaturization and high endurance, and there is still a long way to go for military and commercial applications.

[0002] The flapping-wing aircraft refers to the aircraft whose wings can flap up and down. It can be divided into bird-like flapping-wing aircraft and insect-like flapping-wing aircraft. Due to the current theoretical research on the flapping-wing flight method is still insufficient, and the manufacturing process is highly complicated. Most of the flapping-wing aircraft can not achieve the goal of miniaturization and high endurance, and there is still a long way to go from military and commercial applications

[0003] The design of traditional small flapping-wing aircraft is generally divided into two types. One is that two or more wings are driven and controlled separately, and no steering mechanism is provided. This structure is conducive to improving the flexibility of the flapping-wing aircraft, but the controllability is poor. Structural redundancy is not conducive to the miniaturization of the flapping wing aircraft and the improvement of mechanical efficiency

The second is that the left and right wings flutter in the same phase, and the turning action is realized through the tail fin with adjustable windward angle. This structure is generally only used for the design of bird-like flapping wing aircraft, and is not suitable for the design of bionic insects without tail fins.

[0004] The existing bionic butterfly flapping-wing aircraft is heavy, and the mechanical transmission efficiency is not high. If the flapping-wing aircraft is to be further miniaturized, it is necessary to optimize and innovate the drive structure and control methods
