T-type wing with wavy tailing edges

Abstract

The invention provides a T-type wing with wavy tailing edges. The T-type wing comprises a supporting column (3) and a hydrofoil (4). The supporting column (3) is a straight type supporting column. Thesupporting column (3) and the hydrofoil (4) are perpendicularly connected in the central line position of the hydrofoil (4). The tailing edge of the hydrofoil (4) and the tailing edge of the supporting column (3) are each of a wavy structure, and the crest and trough of the wavy structure are equal in amplitude and are in a sinusoid shape. The tailing edge of hydrofoil (4) is symmetrical about the central line of the hydrofoil (4). The tailing edge of the supporting column (3) and the tailing edge of the hydrofoil (4) are aligned. The hydrofoil (4) is of a leading edge sweep type when lookeddown. By means of the wavy tailing edges of the T-type wing, the flow separation of back sides of blades and vortex in wake can be reduced, fluid can better fit the surface of the wing type, the angleof stall is increased, the lift force is increased, the original damping performance can be kept unchanged, and the T-type wing has a vibration and noise reduction effect.

Description

technical field [0001] The invention relates to a T-shaped wing, in particular to a T-shaped wing with a wavy trailing edge. Background technique [0002] With the continuous development of shipbuilding technology, ship designers have higher and higher requirements for ship comfort and safety. The pitch and heave of the ship will bring continuous changes in the vertical acceleration of the ship, and the vertical acceleration is one of the factors that have the greatest impact on the seaworthiness of the ship during navigation. The seasickness of the staff and passengers on board is the result of the accumulation of vertical acceleration during the ship's navigation. When the vertical acceleration reaches a certain level, it will pose a severe challenge to the structural strength of the ship. Therefore, it is very necessary to reduce the pitch and heave when sailing at high speed, no matter for civilian ships or warships. [0003] As the appendage of the ship, the T-shaped ...

Problems solved by technology

[0004] However, when the general T-shaped wing reduces the vertical motion of the ship when it is sailing, due to the large blocking effect of the wing section, it is often accompanied by large vibration and noise, which is undoubtedly a kind of fatigue damage to the strength of the hull structure. Measuring instruments installed in the bow will also cause greater interference
