The invention relates to the technical field of underwater vehicles, and discloses a flexible empennage structure and an underwater vehicle, the flexible empennage structure comprises a tail rod, a tail line, a gas tank, an air bag and an antenna, the tail rod is connected with the tail line, the tail line is a bendable flexible material, the end, away from the tail rod, of the tail line is connected with the gas tank, the antenna is arranged in the air bag, the air bag is communicated with the gas tank, and the antenna is arranged in the air bag. The tail line is in communication connection with the antenna to transmit signals. When the underwater vehicle sinks underwater and sails, the flexible empennage structure is subjected to the resistance effect of water, the tail line is in a straightened state, and when the underwater vehicle deviates from the set direction, the gas tank and the air bag pull the tail rod through the tail line, restoring torque is applied to the vehicle body through the tail rod, and the underwater vehicle is driven to move. The stability of underwater navigation of the aircraft is improved while the empennage structure is simplified; when the underwater vehicle floats on the water surface, the air bag expands, the tail line is in a bent state, the effect on the underwater vehicle is small, the air bag is exposed out of the water surface, the antenna located in the air bag is exposed out of the water surface along with the air bag, and the communication quality is guaranteed.
本发明涉及水下航行器技术领域,公开了一种柔性尾翼结构及水下航行器,包括尾杆、尾线、气罐、气囊和天线,尾杆上连接有尾线,尾线为可弯折的柔性材料,尾线远离尾杆的一端与气罐连接,天线布置在气囊内,气囊与气罐之间连通,尾线与天线通信连接以传输信号。水下航行器下沉到水下时,水下航行器航行时柔性尾翼结构受到水的阻力作用,尾线处于拉直状态,水下航行器偏离既定方向时,气罐和气囊通过尾线拉扯尾杆,通过尾杆向航行器本体施加回复力矩,简化尾翼结构的同时提高航行器水下航行的稳定性;水下航行器上浮水面时,气囊膨胀,尾线处于弯曲状态,对水下航行器的作用很小,气囊露出水面,位于气囊内的天线随气囊露出水面,保证了通信质量。
