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

[0048] like Figure 7 As shown in the closed diagram of the movable fins of the horizontal fin rearward pop-up stabilization device, when the revolving body AUV 1 does not have high stability requirements, the movable fins 4 are in the position grooves of the fixed fins 3. The pin shaft 5, the long pin shaft 6, the hydraulic push rod 8, the horizontal slideway 9 and the vertical slideway 10 ensure that the movable fin 4 is in a fixed position.

[0049] In the working state with high stability requirements for the revolving body AUV 1, such as Figure 8 As shown in the schematic diagram of the opening of the movable fins of the horizontal fin backward popping up the stabilization device, the hydraulic push rod 8 works and contracts, pulling the long pin 6 to move forward along the longitudinal slide 10, and at the same time, the long pin 6 drives one end of the movable fin 4 forward Move and make it rotate around the short pin 5. Since the distance between the two pins is fixe...

Abstract

The invention discloses a rearward pop-up stabilization device for a revolving body type AUV horizontal fin, which belongs to the fields of fluid mechanics, maneuverability and stability of an underwater vehicle, and comprises an AUV cross-fin rudder and a cross-fin rudder disposed on the horizontal fin of the AUV cross-fin rudder. The horizontal pop-up movable fin mechanism, the left and right horizontal pop-up movable fin mechanisms are symmetrically arranged on the horizontal fins on both sides; the left horizontal pop-up movable fin mechanism includes a movable fin and a fin eject mechanism, and the rear end of the movable fin is The fin ejection mechanism is installed on the end surface of the horizontal fin, and the rotation of the movable fin can be controlled by the fin ejection mechanism, so as to realize the outward ejection or retraction of the movable fin relative to the horizontal fin; the fin ejection mechanism is located at the tail end of the horizontal fin, That is, close to the end of the AUV propeller. This mechanism is compact in structure, does not affect the overall shape and layout of the aircraft, and can be used in the steering system of the revolving AUV.

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 rearward ejection stabilization device for a revolving body type AUV horizontal fin. Background technique [0002] The ocean is an important field for human survival and sustainable development. The development and utilization of the ocean has become one of the basic factors that determine the rise and fall of a country. 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 economy, politics and military, as the main tool of maritime transportation, unmanned underwater vehicle has the characteristics of small size, easy manipulation and high economy, and has become a hot spot of marine engin...
