Description

Technical Field

[0001] The utility model relates to a visible anti-vibration windshield, belonging to the technical field of aviation. Background Art

[0002] At present, the optical equipment on board small multi-purpose aircraft is mostly hung on the belly of the aircraft. When the aircraft is flying, impurities carried in the airflow will cause the lens to wear and tear. The windshield made of fiber composite materials is mostly opaque, which will reduce the field of view of the optical equipment. The general aviation organic glass adopts a flat structure and is easily cracked due to the stress concentration caused by the vibration during flight. It cannot protect the optical equipment on board, and has an adverse effect on flight safety. Utility Model Content

[0004] The utility model adopts the following technical solutions:

[0005] The utility model comprises a cover body fitting frame, an arc-shaped cover body embedded in the cover body fitting frame, lateral support components arranged on both sides of the cover body fitting frame and a C-shaped connecting component arranged on the top of the cover body fitting frame; the C-shaped connecting component is connected to the fuselage.

[0006] The arc-shaped cover body of the utility model is a hyperbolic shape, and its curvature is 0.008-0.01.

[0007] The utility model comprises a lateral support component which is arranged on both sides of the cover body fitting frame and the inner side of the bottom edge and is used to prevent the arc-shaped cover body tip from deforming.

[0008] The utility model C-shaped connecting assembly comprises an inner frame arranged on the inner side of the top of the cover body fitting frame and an outer frame arranged on the outer side of the top of the cover body fitting frame, and both the inner frame and the outer frame are connected to the fuselage.

[0009] The utility model is provided with triangular side wind shielding plates at the outer sides of the force transmission frames on both sides, and the top ends of the side wind shielding plates are folded outwards.

[0010] The arc-shaped cover body of the utility model is made of organic glass.

[0011] The positive effects of the utility model are as follows: the arc-shaped cover body of the utility model is made of plexiglass and has a hyperbolic shape, and its curvature is 0.008-0.01, which reduces wind resistance during flight; the windshield is made of plexiglass, has good light transmittance, and has a good forward field of vision; the force transmission frame reduces air resistance and prevents cracks from occurring in the arc-shaped cover body; the side windshield plate is used to connect the outer surface of the aircraft's belly skin, reducing stress concentration at the tip of the arc corner, and the fitting frame, lateral support assembly and C-shaped connection assembly reduce the vibration of the windshield and prevent the windshield from shaking and causing damage.
