Dive system comprising a submarine and a curtain device connected to the submarine via a tether

Abstract

The present invention relates to a dive system comprising a submarine without a ballast tank and a curtain device connected to the submarine via a tether. The system includes a tether driver installed in the submarine, configured to release or rewind the tether. The curtain device is equipped with a curtain that folds during diving and extends during rising. The system further includes a first propeller connected to the submarine, providing propulsion in the direction of the submarine's diving and rising in the water, and a second propeller connected to the curtain device, providing propulsion in the direction of the curtain device's diving and rising in the water. Without a ballast tank, this system and method enable efficient control of the dive system's movements, enhancing underwater operations.
