The invention relates to an automatic pop-up rudder of an unmanned underwater vehicle and a working method of the automatic pop-up rudder. The problems that a folding rudder plate of an existing pipe-mounted launching unmanned underwater vehicle is limited by the internal space of a launching pipe, the area of the rudder plate is limited, and a rudder plate mechanism cannot be installed are solved. According to the technical scheme, the device comprises a U-shaped base, a pin shaft of the base is sleeved with a torsion spring, the root of each fan blade of a rudder blade set is provided with a hole and penetrates through a rotating shaft of the base through the hole, the root of each rudder blade is provided with a notch, the positions of the notches are in the same line after the rudder blade set is unfolded, a boss is arranged on a rudder plate, one end of the torsion spring is fixed to the base, and the other end of the torsion spring is fixed to the boss. A locking block is arranged on the base at the lower end of the pin shaft, one end of the locking block is sleeved with a locking spring, the other end of the locking block is clamped at the position of a notch of the rudder piece set, limiting pins are arranged on the same side of the root of the fixed rudder piece and the root of the auxiliary rudder piece, and kidney-shaped holes are formed in the auxiliary rudder piece and the rudder plate respectively. The limiting pin of the rear rudder sheet is inserted into the kidney-shaped hole of the front rudder sheet and limited through the kidney-shaped hole.
