Description
This underwater glider of Tianjin University is called Haiyan (Petrel II HUG) Chinese Autonomous Underwater Glider (AUG), which uses the latest hybrid propulsion technology and can work continuously for about 30 days. Compared with the traditional unmanned cableless submersible (AUV), the "Haiyan" is light and thin. It is shaped like a torpedo, 1.8 meters in length, 0.3 meters in diameter, and weighs about 70 kilograms. It combines buoyancy drive and propeller propulsion technology, not only can achieve the same turning and horizontal movement as AUV, but also has the ability of traditional glider profile gliding (that is, performing zigzag movement).

Components
The Haiyan (Petrel II HUG) Chinese Autonomous Underwater Glider (AUG) consists of two parts: the mechanical part and the electrical control part.
Mechanical Parts
The mechanical part can be functionally divided into five subsystems: the pressure hull, the buoyancy regulating unit, the attitude regulating unit, the propeller unit, wings, tail antenna, and the emergency unit.
Electrical Control Parts
The electrical control part of Petrel-II has the following subsystems: the processing unit, the navigation unit, the energy unit, the communication and position unit, and the scientific sensor suites.
Modes of Operation
The Haiyan (Petrel II HUG) Chinese Autonomous Underwater Glider (AUG) has two working modes, buoyancy-driven gliding, and propeller-driven level flight. Petrel-II can automatically switch between the two modes according to commands or environmental circumstances.
