Description

Technical Field

[0001] This utility model relates to the field of aviation equipment technology, and in particular to an integrated aircraft deck for stabilizing and guiding airflow. Background Technology

[0002] Aircraft decks are crucial facilities for aircraft takeoff, landing, and docking. Currently, aircraft decks generally use flat steel plates or simple anti-slip surfaces, which have the following drawbacks: the deck surface lacks a flow-guiding structure, causing rainwater or wash water to accumulate and reduce tire adhesion. At the same time, during aircraft takeoff and landing, the strong downwash generated by the engine or rotor impacts the flat deck and spreads outwards in a disorderly manner, forming an external wash and reflected upward vortex, causing the aircraft to sway laterally and reducing takeoff and landing stability. Traditional solid decks lack pressure relief channels, and the high-speed downwash creates an "air cushion" effect between the deck and the aircraft, generating additional lift disturbances and causing helicopters to "jump." Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is that: in the prior art, the aircraft deck has no flow guiding structure, and the external wash flow, reflected upward vortex and downward wash flow will affect the take-off and landing of the aircraft, causing safety problems.

[0004] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes an integrated air deck for stabilizing and guiding airflow, which includes a plate-shaped main body. The plate-shaped main body extends in an undulating manner in its own thickness direction. The plate-shaped main body is provided with multiple guide protrusions and grooves located between adjacent guide protrusions. The bottom of the groove is provided with a through hole for guiding airflow or water flow through. A support portion is provided on the bottom side of the plate-shaped main body and together with the plate-shaped main body, it encloses and forms an accommodating space M.

[0005] In a preferred embodiment of the integrated flow stabilization and guidance aircraft deck of this utility model: the guide boss is provided with a slope to guide the direction of water flow or airflow.

[0006] In a preferred embodiment of the integrated flow stabilization and diversion flight deck of this utility model, the slope inclination angle is 1°~15°.

[0007] In a preferred embodiment of the integrated flow stabilization and diversion aircraft deck of this utility model: the through holes are arranged at intervals along the extension direction of the groove.

[0008] In a preferred embodiment of the integrated flow stabilization and diversion aircraft deck of this utility model: the support part includes a vertical support member and a side support member, and the accommodating space M is formed by the plate-shaped main body and the mirror-arranged side support member.

[0009] In a preferred embodiment of the integrated flow stabilization and guidance aircraft deck of this utility model: the bottom width of the guide boss is h1, the width of the groove is h2, and the ratio of h1 to h2 is 1:0.6~1:1.

[0010] In a preferred embodiment of the integrated flow stabilization and diversion aircraft deck of this utility model: the diameter of the through hole is d1, and the ratio of the diameter of the through hole d1 to the width of the groove h2 is 1:1.03~1:3.

[0011] In a preferred embodiment of the integrated flow stabilization and diversion aircraft deck of this utility model: the ratio of the height H of the vertical support member to the diameter d1 of the through hole is 1:0.02~1:0.145.

[0012] In a preferred embodiment of the integrated flow stabilization and diversion aircraft deck of this utility model, a support base is further included, which is disposed at the bottom end of the support part and parallel to the plate-shaped main body.

[0013] In a preferred embodiment of the integrated flow stabilization and diversion aircraft deck of this utility model: the support base includes a base plate and connecting buckles disposed on both sides, the connecting buckles being used for rigid connection with the platform beam to achieve deck fixation.

[0014] The beneficial effects of this utility model are as follows: through the three-level drainage of the slope guide boss and groove, through hole and accommodating space, part of the external and downward wash flow can be eliminated, significantly suppressing the "air cushion jump" and lateral sway during the take-off and landing of the aircraft, and improving the stability of take-off and landing. At the same time, the slope of the guide boss can achieve rapid drainage, reduce the time of rainwater residence, and meet the braking effect of the aircraft deck under wet and slippery conditions.

Detailed Implementation

[0016] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0017] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0018] Reference Figure 1 This embodiment provides an integrated airflow stabilization and guidance flight deck, including a plate-shaped main body 1. The plate-shaped main body 1 extends in an undulating manner in its own thickness direction. In this embodiment, the plate-shaped main body 1 constitutes the load-bearing surface of the flight deck. It is integrally formed from high-strength aluminum alloy or composite material. The thickness direction (i.e., the direction perpendicular to the aircraft take-off and landing surface) extends in a periodic undulating manner. The plate-shaped main body 1 is provided with multiple guide protrusions 11 and grooves 12 located between adjacent guide protrusions 11. The grooves 12 extend continuously along the longitudinal direction of the deck. The bottom of the grooves 12 is provided with through holes 13 for guiding airflow or water flow.

[0019] Preferably, the support part 2 is disposed on the bottom side of the plate-shaped main body 1 and together with the plate-shaped main body 1 encloses the accommodating space M. The accommodating space M constitutes a transit buffer chamber for airflow and water flow. The aircraft deck guides the airflow or water flow through the guide boss 11 and flows into the accommodating space M through the through hole 13 provided at the bottom of the groove 12, thereby eliminating some of the external wash flow and downwash flow generated by the aircraft during take-off and landing, which plays a role in improving the stability of the aircraft during take-off and landing. At the same time, it can quickly guide the precipitation and artificial wash water into the groove 12, reducing the water accumulation on the guide boss 11.

[0020] Reference Figures 1-3 As an optional embodiment, the guide boss 11 is provided with a slope 111 for guiding the direction of water flow or airflow. In this embodiment, the guide boss 11 is a strip-shaped raised structure with a trapezoidal cross-section, or it can be other shapes such as triangle, as long as it can guide the airflow or precipitation or artificial washing water generated during the take-off and landing of the aircraft. No specific limitation is made here.

[0021] Furthermore, the inclination angle of the slope 111 is 1°~15°, that is, the angle α between the slope 111 and the horizontal plane is in the range of 1°~15°. In this embodiment, when the angle α is 4°, the centripetal acceleration generated by the downwash airflow on the slope 111 can reach 15m / s², effectively constraining the airflow diffusion angle to be less than 15°.

[0022] Reference Figure 1 As an optional embodiment, the through holes 13 are arranged at intervals along the extension direction of the groove 12. The interval arrangement follows the principle of fluid dynamics optimization to ensure that the airflow and water flow are evenly discharged within the entire length of the groove 12, avoiding local overload or blockage.

[0023] Reference Figure 2 As an optional embodiment, the support part 2 includes a vertical support member 21 and a side support member 22. The accommodating space M is formed by the plate-shaped main body 1, the mirror-arranged support part 2 and support base 3 together to form a closed section with dual functions of bearing and guiding. This support structure ensures the bending stiffness of the plate-shaped main body 1 while forming a sealed chamber to achieve orderly guidance of airflow and water flow.

[0024] Furthermore, the bottom wide side 112 of the guide boss 11 has a width of h1, and the groove 12 has a width of h2. The ratio of h1 to h2 is 1:0.6 to 1:1. In this embodiment, this ratio range is determined based on the coupling optimization of the tire ground pressure distribution law of the aircraft and the fluid confluence efficiency, ensuring that the plate-shaped body 1 achieves the best balance between load bearing, airflow guidance and weight reduction. It should be noted that, in addition to guiding the airflow during the take-off and landing of the aircraft, the slope 111 of the guide boss 11 can also generate a greater friction effect during the take-off and landing of the aircraft.

[0025] Furthermore, the diameter of the through hole 13 is d1, and the ratio of the diameter d1 of the through hole 13 to the width h2 of the groove 12 is 1:1.03 to 1:3. In this embodiment, this ratio range is determined based on the comprehensive optimization of the flow discharge efficiency of the through hole 13 orifice, the strength of the plate structure, and the anti-clogging ability, to ensure that the airflow and water flow achieve maximum flow efficiency and minimum pressure loss when passing through the through hole 13.

[0026] Furthermore, the ratio of the height H of the vertical support member 21 to the diameter d1 of the through hole 13 is 1:0.02 to 1:0.145. In this embodiment, this ratio range is determined based on multi-objective optimization of the pressure relief cavity volume efficiency, structural weight control and fluid kinetic energy dissipation characteristics to ensure that the accommodating space M can fully buffer the high-speed airflow, while ensuring the rigid support effect of the support part 2 during the take-off and landing of the aircraft.

[0027] Reference Figures 1-2 As an optional embodiment, it also includes a support base 3, which is disposed at the bottom of the support part 2 and parallel to the plate-shaped main body 1. The support base 3 serves as the basic load-bearing and installation interface layer of the deck system.

[0028] Preferably, the support base 3 includes a base plate 31 and connecting buckles 32 disposed on both sides. The connecting buckles 32 are used for rigid connection with the platform beam to achieve deck fixation.

[0029] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways, as long as they do not depart from the scope of this utility model.
