Wing deformation structure of water and air amphibious aircraft

Abstract

The invention relates to a wing of an aircraft, in particular to a wing deformation structure of a water and air amphibious aircraft, aiming at solving the problems that the wing, adopting a vertical fin discontinuous deformation structure, of the existing antisubmarine aircraft is poor in stealth performance and aerodynamic performance, has influence on the flight speed and is not beneficial to reduction of radar return signals, and the wing, adopting a structure without a vertical fin, of the existing antisubmarine aircraft is poor in controllability and maneuvering characteristic. The wing deformation structure of the water and air amphibious aircraft comprises a rigidity-variable wing spar, two bending torsion deformation components and two wing ribs; two pneumatic muscle actuators of each bending torsion deformation component are arranged crosswise; the two bending torsion deformation components are respectively arranged at two sides of the rigidity-variable wing spar; two ends of each pneumatic muscle actuator are respectively connected with the two wing ribs; the rigidity-variable wing spar comprises a flexible bearing pneumatic muscle actuator and a wing spar main body; the flexible bearing pneumatic muscle actuator is inserted into a tubular elastic beam; two ends of the tubular elastic beam are respectively connected with the two wing ribs. The wing deformation structure is used for the water and air amphibious aircraft.

Description

technical field [0001] The invention relates to an aircraft wing, in particular to an unmanned anti-submersible air amphibious aircraft with both bending and torsion wing deformation structure. Background technique [0002] Anti-submarine aircraft can be roughly divided into anti-submarine helicopters, ship-borne fixed-wing anti-submarine aircraft, water-based anti-submarine aircraft and shore-based fixed-wing anti-submarine aircraft. Anti-submarine helicopters are widely equipped with various types of combat ships above naval frigates. This kind of anti-submarine force has the advantages of convenient take-off and landing, and the ability to hover and continue to work. At present, the anti-submarine helicopters equipped by various countries mainly include: the "Sea Eagle" of the United States, the "Sea King" of the United Kingdom, the "Super Hornet" of France, and the "Ka-27" of the former Soviet Union. Short, it is difficult to adapt to today's complex and changeable batt...

Problems solved by technology

[0004] The present invention aims to solve the problem that the wing of the existing anti-submarine aircraft uses a vertical tail discontinuous deformation structure, which has poor stealth performance, poor aerodynamic performance, affects flight speed, and is not conducive to reducing radar reflection signals, and has no vertical tail structure. The problem of poor maneuverability and maneuverability, and then provide a wing deformation structure of water-air amphibious aircraft
