Description

Technical Field

[0001] The present invention relates to the technical field of aircraft and its peripheral accessories, and in particular to an aircraft and a deformable wing. Background Art

[0002] With the rapid development of advanced manufacturing technology, improving the aerodynamic efficiency of aircraft has always been the focus of attention and research by aeronautical engineering researchers. A variety of deformable structural designs have emerged for deformable wings. The use of rigid structures can achieve variable curvature to drive wing deformation. The optimized design of the wing can be used to find an airfoil structure with better aerodynamic efficiency. The use of flexible skin structures can achieve continuous deformation of the wing. The use of artificial muscle drive units can achieve bending deformation of the wing. Deformable wings can be divided into large deformation, medium deformation and local deformation. This pneumatic-electric coupled deformable wing structure can achieve large deformation.

[0003] With the continuous development of science and technology, people's requirements for aerodynamic efficiency, weight requirements, fuel consumption, noise, environmental protection, safety and reliability of aircraft are constantly increasing. Morphing is a promising bionic technology that has the potential to make aircraft more economical and sustainable by adjusting the shape of the wing to achieve optimal efficiency under any flight conditions. In order to further reduce flight costs and environmental pollution, it is necessary to deviate more thoroughly from traditional aircraft design. A promising technology that has emerged is active morphing, which enables aircraft to transform their shape in flight and achieve sustainable deformation. In recent years, advanced developments in materials science such as shape memory alloys, compliant mechanisms and piezoelectric materials have made morphing possible. Online optimization has the potential to customize the shape of the wing according to any specific flight conditions to achieve the best aerodynamic performance based on in-flight measurements. Intelligent morphing wings can sense the environment and adjust the shape of the wing to achieve optimal performance in any situation, making it fully adapted to the mission.

[0004] Cai Yong, a teacher at Xi'an Jiaotong University, first proposed a hinged wing skeleton structure and a skin drive unit structure corresponding to the skeleton structure. The drive unit was prepared, and the drive performance was analyzed and optimized. The prepared skin drive unit was assembled with the wing skeleton, and the skin structure produced a 45° bending deformation under the drive of the electric load, meeting the design requirement of a bending deformation angle of 15°. Secondly, a fiber layer was added to the skin drive unit to increase the stiffness adjustment function of the drive unit, provide technical support for the research and development of small variant UAVs, and improve the intelligence of existing wing deformation technology. For mechanical transmission structures, a large friction force will be generated in the process of bending, affecting the aerodynamic efficiency and controllability of the wing during flight.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The purpose of the present invention is to provide an aircraft and a deformable wing to solve the problems existing in the above-mentioned prior art, reduce the friction during the deformation of the wing, and improve the safety and reliability of the wing.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] The present invention provides a deformable wing 100, comprising a plurality of groups of deformation mechanisms 200 connected in sequence, wherein the deformation mechanism 200 comprises a leading edge wing 1, a main body and a trailing edge wing 4 connected in sequence, wherein the main body comprises an airbag 2 and a skin 3 arranged on the upper and lower sides of the airbag 2, the airbag 2 is made of a flexible material, and the airbag 2 is a hollow structure and is divided into an upper cavity and a lower cavity, the upper cavity and the lower cavity are respectively connected to an air source, the skin 3 is connected to the airbag 2, the skin 3 is an intelligent skin 3, and the skin 3 can drive the airbag 2 to deform; between the skin 3 and the airbag 2 A first electrostatic adsorption variable stiffness element is provided, and second electrostatic adsorption variable stiffness elements 5 are connected to both side surfaces of the airbag 2, and main parts of adjacent deformation mechanisms 200 are adsorbed and connected by the second electrostatic adsorption variable stiffness elements 5; third electrostatic adsorption variable stiffness elements 7 are connected to both side surfaces of the trailing edge wings 4, and trailing edge wings 4 of adjacent deformation mechanisms 200 are adsorbed and connected by the third electrostatic adsorption variable stiffness element 7; the skin 3, the first electrostatic adsorption variable stiffness element, the second electrostatic adsorption variable stiffness element 5 and the third electrostatic adsorption variable stiffness element 7 are all connected to a power supply.

[0037] The deformable wing 100 of the present invention includes a plurality of deformation mechanisms 200, wherein the deformation mechanism 200 includes a leading edge wing 1, a main body and a trailing edge wing 4, wherein the airbag 2 includes an upper cavity and a lower cavity, when the air source inflates the upper cavity, the main body bends downward, and when the air source inflates the lower cavity, the main body bends upward; skins 3 are arranged on both upper and lower sides of the airbag 2, and the skins 3 are intelligent skins 3, and when the skin 3 on the upper part of the airbag 2 is energized, the skins 3 can drive the airbag 2 to bend downward When the skin 3 at the bottom of the airbag 2 is energized, the skin 3 can drive the airbag 2 to generate an upward bending deformation. Under the joint action of the skin 3 and the airbag 2, the deformation mechanism 200 can generate continuous deformation. When the deformation mechanism 200 is deformed to a preset angle, the first electrostatic adsorption variable stiffness element between the skin 3 and the airbag 2 is energized, and the air pressure applied to the airbag 2 and the voltage on the skin 3 are removed. The first electrostatic adsorption variable stiffness element can stabilize the deformation mechanism 200 at this preset deformation angle. The deformable wing 100 of the present invention comprises a plurality of groups of deformation mechanisms 200 connected in sequence, and the two sides of the airbag 2 are provided with a second electrostatic adsorption variable stiffness element 5 to realize the adsorption connection of the main parts of the adjacent deformation mechanisms 200, and the trailing edge wings 4 of the adjacent deformation mechanisms 200 are connected by the third electrostatic adsorption variable stiffness element 7. While independently controlling each deformation mechanism 200 to realize its corresponding deformation amount, by controlling the second electrostatic adsorption variable stiffness element 5 and the third electrostatic adsorption variable stiffness element 7, it is possible to control the plurality of groups of deformation mechanisms 200 to realize continuous deformation. The deformable wing 100 of the present invention adopts a control method combining pneumatic and electric, which reduces the friction force in the bending process compared with the motor mechanical drive in the prior art, is conducive to improving the controllability of the wing during flight, and reduces the wing mass at the same time. In addition, when a group of deformation mechanisms 200 fails, it does not affect the normal operation of other deformation mechanisms 200, thereby improving the safety and reliability of the wing during flight.

[0038] It should be explained here that the first electrostatic adsorption variable stiffness element, the second electrostatic adsorption variable stiffness element 5 and the third electrostatic adsorption variable stiffness element 7 are all electrostatic adsorption variable stiffness structures, and the electrostatic adsorption variable stiffness structure is common knowledge to those skilled in the art and will not be described in detail here. In addition, in this specific embodiment, the first electrostatic adsorption variable stiffness element, the second electrostatic adsorption variable stiffness element 5 and the third electrostatic adsorption variable stiffness element 7 are mainly composed of ink, PI film, Pet film, and conductive tape, and are made by screen printing.

[0039] Specifically, the airbag 2 includes a middle partition 201, and a plurality of branches 202 are symmetrically arranged on the upper and lower sides of the middle partition 201. The branches 202 are arranged along the connecting direction of the leading edge wing 1 and the trailing edge wing 4. The branches 202 are hollow structures. The inner cavities of the branches 202 located on the same side of the middle partition 201 are connected to form an upper cavity and a lower cavity, wherein the inner cavities of the branches 202 located on the upper side of the middle partition 201 are connected to form an upper cavity, and the inner cavities of the branches 202 located on the lower side of the middle partition 201 are connected to form a lower cavity. The airbag 2 includes the structure of the middle partition 201 and the branches 202, which ensures that the airbag 2 has a strong deformation ability, thereby improving the deformation range of the deformation mechanism 200.

[0040] In this specific embodiment, the branches 202 are arranged at equal intervals along the direction of the line connecting the leading edge wing 1 and the trailing edge wing 4. The equally spaced branches 202 improve the force uniformity of the airbag 2, and improve the deformation uniformity of the airbag 2 when the skin 3 drives the airbag 2 to generate bending deformation.

[0041] In practical applications, the height of the branch 202 can be set to gradually decrease along the direction from the leading edge wing 1 to the trailing edge wing 4 to achieve a smooth transition between the leading edge wing 1 and the trailing edge wing 4. In practical applications, the height change trend of the branch 202 can also be adjusted according to actual conditions to meet the needs of different aircraft.

[0042] In order to facilitate the connection, connecting plates 203 are provided at both ends of the middle partition 201, and the leading edge wing 1 and the trailing edge wing 4 are both provided with connecting grooves. The ends of the first electrostatically adsorbed variable stiffness element, the ends of the skin 3 and the connecting plate 203 are all extended into the connecting grooves and fixed. In actual operation, the connecting plate 203 can be first extended into the connecting groove and fixed with bolts, and then the skin 3 is covered on the upper and lower surfaces of the airbag 2 and fixed with positioning pins to ensure a tight connection. The connecting plate 203 connected to the leading edge wing 1 is also provided with two air inlets 204, which are used to inflate the upper cavity and the lower cavity respectively. A connecting port is also provided on the leading edge wing 1 to facilitate the extension of the inflation air pipe and connect with the air inlet 204.

[0043] In practical applications, the airbag 2 can be made by 3D printing to reduce the difficulty of processing and manufacturing. The airbag 2 can be made by printing TPU super elastic material. Similarly, the leading edge wing 1 and the trailing edge wing 4 can be made by printing epoxy resin material.

[0044] In this specific embodiment, the skin 3 includes a film 4 and a tape electrode 302 and a thick and thin glass strip 303 arranged on the film 4. The tape electrode 302 is connected to a power source. The number of the thick and thin glass strips 303 is multiple. The thick and thin glass strips 303 are arranged along the connecting direction of the leading edge wing 1 and the trailing edge wing 4. The thick and thin glass strips 303 are connected to the branch 202. When making the skin 3, firstly, the VHB4910 film is pre-stretched by multiples of 4X4, cut and fixed with a metal partition frame, and then the corresponding carbon paste electrode shape is cut out with a laser cutting machine, and respectively attached to the upper and lower surfaces of the film unit, and led out with a conductive electrode for convenient connection with a power source, and then the thick and thin glass strips 303 are bonded with a silicone rubber adhesive on the upper and lower surfaces of the film unit with the carbon paste electrode attached, and dried with a dryer, and then cut and used.

[0045] More specifically, the branch 202 has a slot, and the thick and thin glass strips 303 are plugged and connected to the slot, thereby improving the convenience of connecting the skin 3 and the airbag 2. It should be noted here that the size of the first electrostatic adsorption variable stiffness element is smaller than that of the skin 3 to avoid affecting the connection between the skin 3 and the airbag 2.

[0046] Furthermore, the side of the trailing edge wing 4 is also connected to an elastic body 6, which is a hollow structure. The elastic body 6 is connected to the air source. The elastic body 6 is located between the trailing edge wing 4 and the third electrostatic adsorption variable stiffness element 7. When the adjacent deformation mechanisms 200 are deformed, the elastic body 6 can be inflated, and the elastic body 6 is deformed, thereby "pushing" the third electrostatic adsorption variable stiffness element 7 away from the trailing edge wing 4, ensuring that the adjacent deformation mechanisms 200 can be adsorbed and connected, thereby achieving continuous deformation of the wing. Similarly, the second electrostatic adsorption variable stiffness element 5 connected to the airbag 2 ensures that the main parts of the adjacent deformation mechanisms 200 are adsorbed and connected under the action of the deformation of the airbag 2.

[0047] In other specific embodiments of the present invention, a hard plate 8 is further provided between the elastic body 6 and the third electrostatic adsorption variable stiffness element 7 to ensure the uniformity of force on the third electrostatic adsorption variable stiffness element 7 and improve the structural stability of the wing.

[0048] Furthermore, the present invention also provides an aircraft, including the above-mentioned deformable wing 100, which is beneficial to improving the aerodynamic efficiency of the aircraft during flight by reducing the friction during the bending process of the wing.

[0049] The deformable wing 100 of the present invention adopts the method of gas-electric coupling control, adopts the superposition of multiple groups of deformation mechanisms 200, uses the airbag 2 and the skin 3 to jointly drive the bending deformation of the wing, and sets the first electrostatic adsorption variable stiffness element between the skin 3 and the airbag 2, which can control the bending stability of the mechanism to a certain angle, and realizes the continuous deformation of the wing through the second electrostatic adsorption variable stiffness element 5 between adjacent deformation mechanisms 200, and realizes the smooth transition between multiple groups of deformation mechanisms 200, eliminating the cavity generated by the existing wing structure when bending. The airbag 2 of each group of deformation mechanisms 200, the pressure value input by the proportional valve and computer control can realize the coordinated continuous deformation of a certain shape, and the design of the second electrostatic adsorption variable stiffness element 5 and the airbag 2 can improve the stiffness and load-bearing capacity of the wing unit.

[0050] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
