Aircraft hinge connection device

Abstract

The invention discloses a hinge connecting device of an aircraft. The hinge connecting device comprises a runway-like arm connecting block, a wing hinge block, a longitudinal plate and a piezoelectricbimorph, wherein the longitudinal plate is arranged at the top part and the bottom part of the arm connecting block; lining jackets are arranged in the arm connecting block and the wing hinge block;one end of each lining jacket is connected with a silica gel filling head; the silica gel filling heads are located in the opposite surfaces of the arm connecting block and the wing hinge block; the top parts and the bottom parts of the silica gel filling heads are in one-quarter arc shapes, and are consistent with the right side surface of the arm connecting block and the left side surface of thewing hinge block; the piezoelectric bimorph transversely penetrates through the lining jacket arranged in the arm connecting block to enter the lining jacket arranged in the wing hinge block; the right end of the wing hinge block is fixedly connected with a spherical hinge mechanism. By using combination of the spherical hinge mechanism and a piezoelectric effect, a traditional direct hinging mode is changed, and more effective power transmission is achieved.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a hinge connection device for an aircraft. Background technique [0002] Micro air vehicle is a new research focus and direction in the field of international aviation. Researchers at home and abroad have developed various types of MAVs. According to the current research and development situation, according to the flight mode, they can be divided into: fixed-wing MAVs, rotary-wing MAVs, and flapping-wing MAVs. Compared with fixed-wing MAVs, rotor MAVs The biggest advantage of aircraft is that it can take off and land vertically and hover, which is more suitable for use in more complex environments. However, existing rotorcraft require motors or oil engines to drive the rotor to actively rotate, and the tail rotor is required to offset the impact of the rotor on the body. Torsion, resulting in complex structure, large mass and low aerodynamic efficiency. The flapping-wing micro-...

However, existing rotorcraft require motors or oil engines to drive the rotor to actively rotate, and the tail rotor is required to offset the impact of the rotor on the body. Torsion, resulting in complex structure, large mass and low aerodynamic efficiency. The flapping-wing micro-aircraft is a new type of aircraft that imitates the flight of birds or insects. Compared with miniature fixed-wing and rotary-wing aircraft, its main feature is to lift, hover It is integrated with the propulsion function, and most of the articulation devices of the existing flapping aircraft adopt the form of direct articulation, so that the articulation connection between the aircraft and the wings consumes the kinetic energy of the transmission, and increases the power consumption of the aircraft driving device
