Description

Technical Field

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

[0002] With the rapid development of aerospace technology, hypersonic vehicles have become a key research topic in the modern aerospace field. However, hypersonic vehicles face extreme challenges in terms of aerodynamic loads, thermal environments, and structural stresses. Wings and rudders are key control components of hypersonic vehicles, primarily responsible for adjusting flight attitude and heading. Furthermore, due to the aircraft's extreme lightweight and high fuel consumption requirements, fuel-storage wings and rudders are often required to maximize space utilization. Therefore, the structural design and optimization of these fuel-storage wings and rudders are particularly critical.

[0003] Existing fuel storage wings and rudder wings include honeycomb structures, columnar skeletal structures, and multi-layer composite panels. Each of these structures has its own drawbacks. Honeycomb structures are excessively heavy, columnar skeletal structures have weak stress-bearing capacity, and multi-layer composite panels offer poor thermal insulation. Therefore, a rudder wing structure that combines high load-bearing capacity with strong thermal insulation is urgently needed to meet the increasingly complex service environments of high-speed aircraft. Summary of the Invention

[0007] The vertical thick plate is composed of a long thick plate and a plurality of short thick plates, and the long thick plate is arranged between the connection end of the wing / rudder wing and the fuselage and the perforated fuel tank, and is arranged along the length direction of the wing / rudder wing. Assuming that the length of the wing / rudder wing is L and the width is D, the length of the long thick plate is l, and the distance between the long thick plate and the connection end of the wing / rudder wing and the fuselage is d1, l=L, d1=(0.1-0.25)D; the plurality of short thick plates are distributed between the long thick plate and the perforated fuel tank along the length direction of the wing / rudder wing, and are arranged in a row symmetrically along the center line of the length direction of the wing / rudder wing.

[0025] The vertical thick plate 1 is composed of a long thick plate 11 and a plurality of short thick plates 12, and the long thick plate 11 is arranged between the connection end of the wing / rudder wing and the fuselage and the perforated fuel tank 3, and is arranged along the length direction of the wing / rudder wing. Assuming that the length of the wing / rudder wing is L and the width is D, the length of the long thick plate 11 is l, and the distance between the long thick plate 11 and the connection end of the wing / rudder wing and the fuselage is d1, l = L, d1 = (0.1-0.25) D; the plurality of short thick plates 12 are distributed between the long thick plate 11 and the perforated fuel tank 3 along the length direction of the wing / rudder wing, and are arranged in a row symmetrically along the center line of the length direction of the wing / rudder wing;

[0026] The multiple rows of side trusses 2 are distributed on both sides of the perforated fuel tank 3 along the width direction of the wing / rudder wing and are arranged symmetrically along the centerline of the length direction of the wing / rudder wing; each row of side trusses 2 is composed of multiple vertical rods 21 and multiple diagonal rods 22; the long thick plate 11 is provided with multiple vertical grooves, and the vertical rods 21 at one end of each row of side trusses 2 are embedded in the vertical grooves of the long thick plate 11, and the other end is located at the tail streamline end of the wing / rudder wing;

[0027] The plurality of intermediate oblique columns 4 are arranged in the holes of the perforated fuel tank 3 and are arranged symmetrically along the center line of the wing / rudder wing length direction;

[0028] The vertical thick plates 1 and the vertical rods 21 are vertically connected to the upper and lower panels of the wing shell 5 , and the oblique rods 22 and the middle oblique columns 4 are connected to the upper and lower panels of the wing shell 5 at an inclined angle.

[0029] The shape and size of the perforated fuel tank 3 described in this embodiment are determined according to the specific requirements of the aircraft, and the position and size of the perforations are determined by the position and size of the middle inclined column.

[0030] The shape and dimensions of the wing shell 5 described in this embodiment are determined by the specific requirements of the aircraft. It is made of a high-temperature, high-strength alloy to ensure stress-bearing capacity in high-temperature environments. It is connected to the vertical thick plates 1, side girders 2, and central diagonal columns 4 through welding to ensure structural integrity and sealing.

[0031] In this embodiment, vertical thick plates 1, side girders 2, and central diagonal columns 4 connect the upper and lower panels of the wing shell 5, forming the wing and rudder fins as a single unit. The perforated fuel tank 3 and wing shell 5 are both sealed structures, with the gap between them filled with thermal insulation 6 to isolate the perforated fuel tank and achieve a thermal insulation effect.

[0032] In this embodiment, the vertical slabs 1, side girders 2, and central diagonal columns 4 are the primary components that bear stress on the wings and rudder, maintaining overall structural stability. The vertical slabs 1 are composed of multiple long, thick sections perpendicular to the wing shell 5, consisting of long slabs 11 and short slabs 12. The short slabs 12 are primarily designed to match the shape of the fuel tank, maximizing the structure's stress-bearing capacity.

[0033] In this embodiment, the vertical rod 21 at one end of the side truss beam 2 is embedded in the vertical groove of the long thick plate 11 to form a stable cross-tenon structure, thereby greatly improving the overall stability of the structure.

[0034] In this embodiment, the middle oblique columns 4 are all oblique columns that pass through the perforated fuel tank 3 and are inclined at a certain angle to the upper and lower panels of the wing shell 5. The middle oblique columns 4 in two adjacent rows are staggered to form a cross, which facilitates coordinated strain and deformation control.

[0036] The tail of a wing is generally a streamlined curved surface, which is mostly a semicircle. In this specific embodiment, the streamlined end of the tail is the starting point of the curved surface of the wing.

Multiple columns and trusses are used in areas with high deformation to significantly reduce density, while maintaining a certain degree of deformation tolerance and improving the structure's thermal insulation properties, achieving multifunctional optimization of the wing and rudder.

[0039] This implementation introduces a truss structure into the bridge. On the one hand, it forms a cross-tenon between the truss and the thick plate, thereby greatly improving the overall stability of the structure and better transferring stress. On the other hand, in areas with large deformation and stress, the truss structure has greater stress bearing capacity and strain coordination ability, and also achieves weight reduction, which is a highly creative breakthrough.
