Problems solved by technology

Common underwater vehicles usually have a low navigation speed, and do not require high maneuverability of the vehicle, and the layout forms are also flexible and diverse. The shape required by some specific functions, such as cuboid or bionic shape, the commonly used methods to change the navigation attitude of the aircraft in the low-speed navigation state mainly include thrust vector control, multiple propeller control, fin-rudder combination control or water jet propulsion control, thrust vector control and The water jet propulsion device has good maneuverability when the aircraft is sailing at low speed, but it is more difficult to control when the aircraft is sailing at high speed. The control of multiple propellers has good maneuverability at low speed, but it is difficult to play more at high speed. The propeller control is efficient and multiple propellers are easy to increase the resistance of the attached body, which is not good for the navigation of the aircraft; the fin-rudder combination device has a simple structure and is widely used. Although its low-speed maneuverability is relatively low, it has better high-speed maneuverability and is relatively easy to control Realized; So far, there are not many rudder types that can handle well in high-speed and low-speed sailing conditions

Embodiment 1

[0029] A foldable double-sided rudder A, the foldable double-sided rudder A includes two opposing rudder surfaces 1, connected to the airfoil end plate 5 at the top of the two rudder surfaces 1, and adopts two rudder surfaces parallel to each other 1 As a group of control surfaces, compared with a single-sided rudder with the same aspect ratio, it can provide greater steering force and steering moment at the same incoming flow velocity; the airfoil end plate 5 connected to the rudder surface 1 can prevent the rudder end surface from Go around the flow to further improve the efficiency of the rudder. When the attitude of the aircraft remains unchanged, the double-sided rudder does not provide control force. When there is an external disturbance, the double-sided rudder can generate subversive moment to organize the attitude change of the aircraft and improve the navigation stability of the aircraft. sex;

Embodiment 2

[0036] An underwater vehicle, said underwater vehicle comprises an underwater vehicle main body 6, four embodiment-folding double-sided rudders A, a steering gear, and four underwater vehicle main body 6 tails. The aircraft main body 6 and the folding double-sided rudder A are connected by the steering gear shaft 7 on the steering gear.

[0037] The main body 6 of the underwater vehicle is in the shape of a revolving body, and the main body of the underwater vehicle is composed of a curved head section, a curved tail section and a parallel middle section, and a stabilizing fin 8 and a propeller 9 are installed on the shell of the curved tail section. Generally speaking, for the aircraft, the position and size of the stabilizer fin 8 can be used to change the position of the center of pressure of the aircraft when the navigation angle of attack is small, thereby changing the maneuverability of the aircraft. The flow field has a certain rectification effect, which is conducive t...

Abstract

The invention relates to a folding double-face rudder and an underwater vehicle with the double-face rudder. The double-face rudder comprises two rudder faces arranged oppositely and a base connectedbetween the two rudder faces. The folding double-face rudder has the beneficial effects that the double-face rudder has the high rudder effect relative to a single rudder face, and under the conditionof the same aspect ratio, the double-face rudder has larger control force and control torque; the double-face rudder can be folded to the tail of the vehicle, the mounting size is reduced, and when acarrying platform suffers from size limiting, the vehicle with the folding rudder faces has high adaptability; according to the vehicle controlled by the double-face rudder, the posture of the vehicle can be effectively adjusted under the conditions of a low speed and a high speed; and relative to other underwater vehicles, the underwater vehicle has the advantages of being simple in structure and flexible in control form and has the characteristics of energy saving, high efficiency and stability especially for the underwater high-speed navigational status.

Description

technical field [0001] The invention relates to the field of underwater vehicle design, and relates to a foldable double-sided rudder and an underwater vehicle with the double-sided rudder. Background technique [0002] With the improvement of deep-sea detection technology and the maturity of deep-water operation technology, the development of underwater vehicles is getting faster and faster. Especially in the military field, the application of unmanned underwater robots is becoming more and more extensive. Common underwater vehicles usually have a low navigation speed, and do not require high maneuverability of the vehicle, and the layout forms are also flexible and diverse. The shape required by some specific functions, such as cuboid or bionic shape, the commonly used methods to change the navigation attitude of the aircraft in the low-speed navigation state mainly include thrust vector control, multiple propeller control, fin-rudder combination control or water jet propu...
