Problems solved by technology

However, this technical solution cannot be applied to the existing rotary AUV due to the need to install the main and ailerons, and its internal space and shape have undergone major changes.
Secondly, its dual-mode navigation of gliding and high-speed direct flight cannot match most of the existing rotary AUVs that rely on power systems such as propellers, and its applicability is greatly limited.
At the same time, this technical solution is a related solution to the dynamic instability of high-speed direct navigation, and cannot effectively solve the problem of AUV low-speed navigation instability under low-speed or micro-speed conditions below 3kn.

Embodiment approach

[0047] like Image 6 As shown in the closed diagram of the movable fins of the horizontal fin lateral pop-up stabilization device, when the revolving body AUV 1 does not have high stability requirements, the movable fin mechanism 4 is in the position slot of the fixed fin 3 and the horizontal fin. In the middle, the fixed position of the movable fin 4 is ensured by the hydraulic push rod 5, the double pin shaft 9, the parallel slideway 11, and the single pin shaft 12.

[0048] In the working state with high stability requirements for the revolving body AUV 1, such as Figure 7 As shown in the schematic diagram of the opening of the movable fin of the lateral pop-up stabilization device for the horizontal fin, the hydraulic push rod 5 begins to extend, pulling the single pin 12 hinged to it, thereby driving the movable fin 4 to start to move, and the parallel on the movable fin 4 The slideway 11 cooperates with the double pin shaft 9 on the fixed fin 3 to restrict the movable ...

Abstract

The invention discloses a lateral pop-up stabilization device for a revolving body type AUV horizontal fin, belonging to the fields of fluid mechanics, maneuverability and stability of an underwater vehicle; comprising an AUV cross-fin rudder and a cross-fin rudder disposed on the horizontal fin of the AUV cross-fin rudder The laterally ejected movable fin mechanism, the left and right laterally ejected movable fin mechanisms are symmetrically arranged on the horizontal fins on both sides; the laterally ejected movable fin mechanism includes a movable fin and a fin ejection and retraction mechanism, the described The middle part of the movable fin is installed on the end surface of the horizontal fin through the fin pop-up and retraction mechanism, and the movable fin can be controlled to reciprocate along a straight line perpendicular to the AUV axis through the fin eject and retract mechanism, so that the movable fin is outward relative to the horizontal fin. The action of ejecting or retracting; the fin ejecting and retracting mechanism is located in the middle of the horizontal fin; this mechanism is compact in structure, does not affect the overall shape and layout of the aircraft, and can be used in a revolving AUV steering system.

Description

technical field [0001] The invention belongs to the fields of fluid mechanics, maneuverability and stability of an underwater vehicle, and in particular relates to a lateral ejection stabilization device for a revolving body type AUV horizontal fin. Background technique [0002] With the rapid development of human society, the demand for energy, food and other resources has greatly increased, while the resources of land have been consumed by human beings. The ocean covering four-fifths of the surface contains rich resources. Physical Geographical Unit Therefore, the 21st century is the Ocean Century, and the ocean will become the main field of competition for international development, including new economic competition guided by high technology. How to explore and exploit marine resources has become one of the most popular questions in this century. Strategically important in economics, politics and military, as the main tool of maritime transportation, unmanned underwater...
