A forward pop-up stabilization device for a revolving body type AUV horizontal fin

Abstract

The invention relates to a forward pop-up stabilization device for a revolving AUV horizontal fin, which belongs to the fields of fluid mechanics, maneuverability and stability of an underwater vehicle. 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 hydraulic eject mechanism, and the front end of the movable fin is ejected by hydraulic pressure The mechanism is installed on the end face of the horizontal fin, and can control the rotation of the movable fin plate through the hydraulic ejection mechanism to realize the outward ejection or retraction of the movable fin relative to the horizontal fin; the hydraulic ejection mechanism is located at the front end of the horizontal fin. The invention can quickly realize the deceleration effect by popping up the stabilization device, and the deceleration effect is increased by 30%; at the same time, the area of ​​the control fin plate is increased by 70%, and the extension of the fin plate is increased by 460%. The present invention increases the wetted area of ​​the stabilizing fin after the horizontal fin is ejected.

Description

technical field [0001] The invention belongs to the fields of fluid mechanics, maneuverability and stability of an underwater vehicle, and particularly relates to a forward pop-up 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 ve...

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.
