variable angle of attack t-wing

Abstract

The invention discloses a T-shaped wing with a variable angle of attack, which comprises: a tie rod, a vertical wing, a horizontal wing, a fixed shaft and a movable shaft; the horizontal wing and the vertical wing are mated and connected; a longitudinal groove; the vertical wing has a horizontal portion and a vertical portion; the lower end of the vertical portion is placed in the longitudinal groove; the pull rod is inserted into the vertical portion along the vertical direction; the vertical The lower end of the part is provided with a curved hole matched with the movable shaft; the movable shaft is connected to the horizontal wing through the curved hole and the pull rod; the lower end of the vertical part is connected to the horizontal wing through a fixed shaft; the present invention can To solve the problem that the T-shaped wing provided by the prior art has poor anti-rolling effect due to the non-adjustable or timely adjustment of the horizontal wing angle of attack, the present invention has a better anti-rolling effect and can efficiently reduce heave, making the ship It is safer and more comfortable during operation, and the installation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of ship design, and in particular relates to a variable angle of attack type T-shaped wing. Background technique [0002] Ships are prone to encounter extreme sea conditions when sailing, and the ship produces large heave and pitch, which reduces the maneuverability, safety and comfort of the ship. In order to reduce the adverse effects of vertical motion on the speed and structural safety of ships when navigating in waves, various anti-rolling devices have emerged, among which T-shaped wing is a simple-structured, low-cost and effective anti-rolling device that is widely used. focus on. [0003] At present, the T-wings on the market are mainly divided into two types, one is fixed and non-adjustable angle-of-attack T-wings, this type of T-wings cannot actively adjust the angle of attack according to the state of the ship, and can only passively withstand the pressure brought by the state of the ship. The o...

Problems solved by technology

[0003] At present, the T-wings on the market are mainly divided into two types, one is fixed and non-adjustable angle-of-attack T-wings, this type of T-wings cannot actively adjust the angle of attack according to the state of the ship, and can only passively withstand the pressure brought by the state of the ship. The other type is the adjustable angle of attack T-wing, but it can only predict an angle of attack according to the possible sea conditions before the ship travels, and it cannot be changed in time during the ship’s travel; using the existing technology These two kinds of T-shaped wings will cause poor anti-rolling effect due to the non-adjustable or timely adjustment of the horizontal wing angle of attack, resulting in unsatisfactory comfort and safety of the ship.
