Technical Field

The invention relates to the technical fields of variable aircraft design, airfoil deformation mechanism design and aircraft mechanism transmission, in particular to a coupling deformation mechanism device for pushing out wings, rotating out wings and operating wings and a working method.

Background

Modern aircraft are moving towards high mach numbers, high maneuverability, and ultra-far attack ranges, which require their ability to accommodate multiple flight modes: subsonic flight, transonic flight, supersonic flight, etc., and should have good handling, maneuverability, good lift-drag ratio, large pitch angle range, stable flight, easy handling, etc. The aerodynamic profile of a simple fixed-wing aircraft hardly meets the requirements, so that the deformable airfoil surface becomes a hot spot for research at home and abroad at present. The deformed airfoil surface mainly comprises an expandable airfoil surface, a folding airfoil surface, a flexible deformed airfoil surface and the like. The deformed airfoil can adapt to the aircraft to provide better aerodynamic lift-drag ratio characteristics under different flight conditions, and the lift force of the aircraft is improved by changing the lift surface of the airfoil, so that the fuel utilization rate is improved, and the flight distance is increased.

The difficulty of the structural design of the variant aircraft is that: 1. the design problem of the internal structure of the variant wing with large deformation and high bearing capacity is solved; 2. the deformation decision problem of the variant wing under different flight conditions is solved; 3. the problems of drive control and stiffness retention of airfoil deformation at extreme high mach conditions. Technical means such as multidisciplinary optimal design, intelligent material and structural design provide feasible thinking for variant aircraft research.

The large-scale deformation of the aircraft is the most effective, reliable and direct deformation mode of the variant aircraft. The mature deformation mode of the aircraft at the present stage mainly comprises local small deformation and medium-scale deformation, has certain limitation on the whole flight mode of the aircraft, and has little improvement on the flight efficiency of the aircraft. The aircraft is deformed in a large scale, the requirements of different flight modes are met mainly by changing the overall aerodynamic configuration of the aircraft, wherein the most typical deformation mode is to take the main aerodynamic lift component wing of the aircraft as a deformation object, and the influence of the large-scale deformation on the appearance structure of the aircraft is the greatest, and the degree of change on the aerodynamic performance of the aircraft is the greatest.
