Problems solved by technology

[0003] Existing aircraft skins are made of metal materials such as aluminum alloys. Usually, paint is applied to the surface of the metal skin to prevent the skin from being corroded by substances such as acid rain. However, the protective effect of paint is limited and cannot completely prevent the skin from Corroded by unfavorable substances

Embodiment Construction

[0017] like figure 1 Shown is an acid rain-resistant airfoil, which includes an upper skin and a lower skin, and the cladding 3 formed by the upper skin and the lower skin includes a front cladding 3-1 and a rear cladding 3 -2, the front cladding 3-1 of the rectangular strip structure is equipped with a horizontal strip-shaped water spray head 3-1-1, and the water spray head is connected with the water spray device in the rear cladding 3-2; the front The outer cladding 3-1 is connected with the rear cladding 3-2 through a rotating shaft 3-3.

[0018] like figure 2 As shown, a hydraulic support rod 2 is provided between the front cladding 3-1 and the rear cladding 3-2.

[0019] like image 3 As shown, further, the surface of the upper skin and the lower skin is covered with a polyolefin layer 1 .

[0020] With the above structure, when unfavorable substances such as acid rain fall on the surface of the skin, under the control of the water spray device, the water sprayed fr...

Abstract

An acid-rain erosion resistant wing comprises an upper skin and a lower skin. A cladding formed by the upper skin and the lower skin comprises a front cladding and a rear cladding. Horizontal-bar barrier-shaped sprinkler heads are arranged on the front cladding with a rectangular bar structure. The sprinkler heads are connected to a water sprinkler in the rear cladding. The front cladding and the rear cladding are connected through a rotating shaft. By the above structure, when unfavorable substances such as acid rain, etc. fall on the surface of the skin, the barrier-shaped sprinkler heads sprinkle water under the control of the water sprinkler so as to easily and fully wash out the unfavorable substances on the skin. Thus, the metallic skin is prevented from being eroded.

Description

technical field [0001] The invention relates to a component of a wing, in particular to a skin covering the surface of the wing. Background technique [0002] The role of the aircraft skin is to maintain the shape of the aircraft so that it has good aerodynamic characteristics. After the skin is subjected to aerodynamic action, the force is transmitted to the connected fuselage and wing frame. The force is complex, and the skin is in direct contact with the outside world. Therefore, not only the skin material is required to have high strength and good plasticity, but also a smooth surface. It has high corrosion resistance. [0003] Existing aircraft skins are made of metal materials such as aluminum alloys. Usually, paint is applied to the surface of the metal skin to prevent the skin from being corroded by substances such as acid rain. However, the protective effect of paint is limited and cannot completely prevent the skin Corroded by unfavorable substances. Contents o...
