Description

Technical Field

[0001] The invention belongs to the technical field of aerospace manufacturing. Background Art

[0002] As the demand for the flight speed of hypersonic aircraft in the aerospace field increases, the hypersonic aircraft manufactured also need to become lighter and more compact. In order to solve the problem of severe lack of fuel storage during the weight loss of aircraft, an innovative design that integrates fuel storage function with wing and rudder wing structure function is often adopted. This design can effectively utilize the internal space of the rudder wing, reduce the overall weight, optimize the fuel distribution, and improve the stability and range of the aircraft. It is the main optimization and design direction of today's hypersonic aircraft.

[0003] Unlike traditional aircraft, the wings and rudders of hypersonic aircraft will face greater heat environments and huge aerodynamic loads. These high-temperature thermal environments bring about problems such as material thermal expansion, strength attenuation, and heat transfer to the fuel tank, which puts higher demands on the structural strength and thermal insulation performance of the rudder and wing structures. Existing thermal insulation structures often use honeycomb panel insulation structures, plate rib insulation structures, columnar insulation structures, etc., but these thermal insulation structures have the limitations of poor thermal insulation capabilities, unavoidable thermal bridges, and excessive weight. There is still a lot of room for optimization and improvement in the lightweight and anti-thermal insulation performance of oil storage wings and rudder wings. Summary of the invention

[0004] The present invention aims to solve the problems of lightweight, high stress coordination and strong thermal insulation requirements faced by existing oil storage wings and rudder wing structures, and further provide a columnar support with a suspended oil tank wing / rudder wing with a stress coordination platform.

[0005] A columnar support with a suspension tank wing / rudder wing with a stress coordination platform, which is composed of an outer skin, a middle thermal insulation layer, a perforated suspension tank, a plurality of supporting vertical columns, a plurality of side coordination columns and a plurality of perforated coordination columns; the outer skin is a sealing structure composed of an upper outer skin, a lower outer skin and a side outer skin;

[0006] A plurality of holes are arranged in the middle of the perforated suspension oil tank; the gaps around the perforated suspension oil tank and between the upper and lower surfaces and the outer skin, and the holes of the perforated suspension oil tank are filled with a middle insulation layer, and a plurality of supporting vertical columns, a plurality of side coordination columns and a plurality of perforated coordination columns are arranged in the middle insulation layer;

[0007] The plurality of supporting vertical columns are distributed along the length direction of the wing / rudder wing between the connecting end of the wing / rudder wing and the fuselage and the perforated suspension oil tank, and are arranged in a row along the axis of the center line of the length direction of the wing / rudder wing in a symmetrical manner; the supporting vertical columns are composed of a top vertical column stress coordination platform, a bottom vertical column stress coordination platform and an intermediate vertical column, and the top vertical column stress coordination platform and the bottom vertical column stress coordination platform are respectively arranged at both ends of the intermediate vertical column, and the cross-sectional centers of the top vertical column stress coordination platform, the bottom vertical column stress coordination platform and the intermediate vertical column coincide;

[0008] The plurality of side coordination columns are distributed on both sides of the perforated suspension oil tank along the width direction of the wing / rudder wing, and are arranged symmetrically along the center line of the length direction of the wing / rudder wing;

[0009] The plurality of perforated coordination columns are arranged in the holes of the perforated suspension oil tank and are arranged symmetrically along the center line of the wing / rudder wing length direction;

[0010] The plurality of supporting vertical columns are vertically connected to the upper outer skin and the lower outer skin, and the plurality of side coordination columns and the plurality of perforated coordination columns are connected to the upper outer skin and the lower outer skin at an inclined angle.

[0011] The beneficial effects of the present invention are:

[0012] The present invention provides a columnar support with a suspended fuel tank / rudder wing structure design with a stress coordination platform, and the connected column is passed through the fuel tank by digging a hole. The thermal connection between the wing / rudder wing outer skin and the fuel tank can be effectively avoided, the heat propagation is blocked to the greatest extent, and the heat insulation ability of the structure is greatly improved.

[0013] The present invention relies on the structure of the perforated fuel tank to divide different areas to achieve different functions. The key stress-bearing area can avoid the fuel tank through perforations, thereby effectively ensuring the stability of the overall structure and greatly improving the stress bearing capacity of the wing / rudder wing. At the same time, a more reasonable distribution reduces the number of columns, further reduces the mass of the wing and rudder wing, and further improves the load resistance of the wing and rudder wing while achieving lightweight.

[0029] The technical solution of the present invention is not limited to the specific implementation modes listed below, but also includes any combination of the specific implementation modes.

[0030] Specific implementation method 1, combined with Figures 1 to 11 Specific description: This embodiment is a columnar support with a suspension tank wing / rudder wing with a stress coordination platform, which is composed of an outer skin 1, a middle thermal insulation layer 2, a perforated suspension tank 3, a plurality of supporting vertical columns 4, a plurality of side coordination columns 5 and a plurality of perforated coordination columns 6; the outer skin 1 is a sealing structure composed of an upper outer skin 11, a lower outer skin 12 and a side outer skin 13;

[0031] A plurality of holes are arranged in the middle of the perforated suspension oil tank 3; the gaps around the perforated suspension oil tank 3 and between the upper and lower surfaces and the outer skin 1, and the holes of the perforated suspension oil tank 3 are filled with the middle insulation layer 2, and a plurality of supporting vertical columns 4, a plurality of side coordination columns 5 and a plurality of perforated coordination columns 6 are arranged in the middle insulation layer 2;

[0032] The plurality of supporting vertical columns 4 are distributed along the length direction of the wing / rudder wing between the connecting end of the wing / rudder wing and the fuselage and the perforated suspension oil tank 3, and are arranged in a row along the axis of the center line of the length direction of the wing / rudder wing in a symmetrical manner; the supporting vertical columns 4 are composed of a top vertical column stress coordination platform 41, a bottom vertical column stress coordination platform 42 and an intermediate vertical column 43, and the top vertical column stress coordination platform 41 and the bottom vertical column stress coordination platform 42 are respectively arranged at both ends of the intermediate vertical column 43, and the cross-sectional centers of the top vertical column stress coordination platform 41, the bottom vertical column stress coordination platform 42 and the intermediate vertical column 43 coincide;

[0033] The plurality of side coordination columns 5 are distributed on both sides of the perforated suspension oil tank 3 along the width direction of the wing / rudder wing, and are arranged symmetrically along the center line of the length direction of the wing / rudder wing;

[0034] The plurality of perforated coordination columns 6 are arranged in the holes of the perforated suspension oil tank 3 and are arranged symmetrically along the center line of the wing / rudder wing length direction;

[0035] The plurality of supporting vertical columns 4 are vertically connected to the upper outer skin 11 and the lower outer skin 12 , and the plurality of side coordination columns 5 and the plurality of perforated coordination columns 6 are connected to the upper outer skin 11 and the lower outer skin 12 at an inclined angle.

[0036] The shape and size of the outer skin 1 described in this embodiment are determined according to the specific requirements of the aircraft, and its material is a high-temperature high-strength alloy to ensure the stress bearing capacity in a high-temperature environment. The upper outer skin 11, the lower outer skin 12 and the side outer skin 13 are connected by welding to ensure sealing. The upper outer skin 11 is the top structure of the outer skin 1, and it and the lower outer skin 12 of the bottom structure of the outer skin 1 together constitute the main component of the wing / rudder wing that rubs against the air and bears stress and heat, while the side outer skin 13 is the structure on both sides of the wing / rudder wing, the connection structure around the fuselage and the streamlined structure of the wing edge.

[0037] The overall structure of the wing / rudder wing in this embodiment is, from top to bottom, an upper outer skin 11 , a middle thermal insulation layer 2 , a perforated suspension oil tank 3 , a middle thermal insulation layer 2 and a lower outer skin 1 .

[0038] The middle insulation layer 2 described in this embodiment is filled with aerogel, which is artificially stuffed between the outer skin 1 and the perforated suspension oil tank 3, removing all the space supporting the vertical columns 4, the side coordination columns 5 and the perforated coordination columns 6, thereby completely isolating the perforated suspension oil tank 3 and avoiding the formation of thermal bridges.

[0039] In this embodiment, the perforated suspension oil tank 3 has a large hole in the middle, which is convenient for the perforated coordination column 6 to pass through, and does not contact any components except the middle insulation layer 2, so it is in a state of floating up and down according to the force conditions of the wing / rudder wing.

[0040] The supporting vertical column 4 of this embodiment is a row of vertical column structures, and its upper and lower sides include two parts: a top vertical column stress coordination platform 41 and a bottom vertical column stress coordination platform 42, which are used to relieve stress concentration. The supporting vertical column 4 is located closest to the fuselage connection and does not pass through the perforated suspension oil tank 3. It is the largest load-bearing component.

[0041] The side coordination column 5 of this embodiment is an inclined column that does not pass through the perforated suspension oil tank 3. When the inclination angle of the side coordination column 5 is 60° to 80°, the top coordination column stress coordination platform 51 and the bottom coordination column stress coordination platform 52 are included on the upper and lower sides of the side coordination column 5 to relieve stress concentration. When the inclination angle of the side coordination column 5 is less than 60°, the side coordination column 5 does not need the upper and lower stress coordination platforms.

[0042] In this embodiment, the perforated coordination column 6 connects the upper outer skin 11 and the lower outer skin 12 and is inserted in the middle insulation layer 2 and the perforated suspension oil tank 3 to maintain the structural strength of the rudder wing. The perforated coordination column 6 is an inclined column with a certain inclination angle with the outer skin, and two adjacent rows of coordination columns are staggered to form a cross, which is convenient for coordinated deformation control of strain.

[0043] In this embodiment, the supporting vertical columns 4 , the side coordination columns 5 and the perforated coordination columns 6 are connected to the outer skin 1 by welding.

[0044] The shape and size of the perforated suspension oil tank 3 described in this embodiment are determined according to the specific requirements of the aircraft, and the perforation position and size are determined by the shape and size of the outer skin. The material of the perforated suspension oil tank 3 is a lightweight aluminum-lithium alloy.

[0047] This implementation method relies on the structure of the perforated fuel tank to divide different areas to achieve different functions. In the key stress-bearing area, the fuel tank can be avoided by perforation, thereby effectively ensuring the stability of the overall structure and greatly improving the stress bearing capacity of the wing / rudder wing.
