Embodiment Construction

[0031] The high-performance water rudder of the amphibious aircraft provided by the present invention is explained below in conjunction with accompanying drawing.

[0032] Such as Figure 1-5 As shown, the present invention provides a high-performance water rudder for an amphibious aircraft, and adjusts and optimizes the structure of the commonly used water rudder 9 lines of the amphibious aircraft 1, and makes the water rudder performance significantly in a typical state through targeted design. improvement.

[0033] The present invention adjusts the structure and optimizes the design of the line type of the commonly used water rudder 9, wherein the commonly used water rudder 9 is composed of the water rudder main body 3 and the protruding structure 4 on the front side, and provides a high-performance amphibious aircraft 1 through modification design. A water rudder 10, the high-performance water rudder 10 is composed of a water rudder main body 3, an upper end surface baffl...

Abstract

The invention provides a water rudder of an amphibious aircraft. The water rudder comprises a water rudder body (3), a fish-shaped rectifying tail (5) and an upper end face flow baffle (6). The water rudder main body (3) is in a wing shape; the upper end face flow baffle (6) is in a direct trapezoid shape and is arranged on the upper end face of the water rudder body (3). And the fish-shaped rectifying tail (5) is an isosceles right triangle prism and is arranged at the tail edge of the water rudder main body (3). The structure is simple, large steering torque can be provided for the amphibious aircraft when the amphibious aircraft slides on the water surface at a low speed, and efficiency can be increased by 30% or above under the target working condition.

Description

technical field [0001] The invention belongs to the field of hydrodynamic design of amphibious aircraft, in particular to a water rudder of an amphibious aircraft. Background technique [0002] The surface maneuvering performance of an amphibious aircraft is a performance that must be studied for every amphibious aircraft. In the process of water surface taxiing, good maneuvering performance will greatly shorten the water surface voyage, which is important for improving the safety of the water surface taxiing of the amphibious aircraft. effect. [0003] Due to the influence of the ground-grazing angle of the fuselage when taking off on the ground, the water rudders used by domestic and foreign amphibious aircraft are mainly small-aspect-ratio water rudders, and the small-aspect-ratio water rudders have serious end-face flow phenomenon. Especially in the high-speed taxiing state, the rudder effect of the water rudder will be seriously reduced, and it is difficult to provide ...
