Novel submersible with folding hang gliders

Abstract

The invention discloses a novel submersible with folding hang gliders. The novel submersible with the folding hang gliders comprises a hull body. A bow body of the hull body is provided with a bow rudder. Two sides of the middle of the hull body are provided with the symmetrical hang gliders. A tail part of the hull body is provided with a stern fin and a stern rudder. The stern rudder is connected with the hang gliders through the stern fin. The tail part of the hull body is further provided with a direction rudder through a vertical tail fin. The hull body is internally provided with a gravity adjusting mechanism. Two sides in the tail part of the hull body are provided with multiple groups of symmetrically installed hang glider folding and unfolding mechanisms. The submersible is simplein structure, the hang gliders are folded and unfolded in a rear part of the submersible, and a lift force for gliding is provided to the submersible. The hang gliders are longitudinally arranged along a length direction of the hull body of the submersible, and easily folded. Two sides of a gravity center of the submersible are provided with a water tank for adjusting a net buoyance of the submersible. A combined change of the gliding lift force and the net buoyance of the submersible can realize wave-shaped gliding movement of the submersible in the ocean, so the low-noise sailing is realized, and the underwater invisibility of the whole submersible is improved.

Description

technical field [0001] The invention relates to the technical field of deep sea equipment, in particular to a novel submersible with folding hang gliding wings. Background technique [0002] At present, all submersibles use propellers as propellers, which are the main noise signal source of the entire submersible. The size of the propeller of a large submersible is relatively large, so its noise signal strength is difficult to reduce, which is not conducive to the underwater invisibility of the entire submersible. [0003] With the development of glider hydrodynamic theory and technology, some small aircraft in the air and underwater can carry out long-term and long-distance unpowered gliding. Since the power system of the aircraft may not work when gliding forward, the noise intensity of the aircraft during gliding is relatively low. However, in order to provide sufficient lift, the wingspan of the glider's wings is generally relatively large, almost equal to the fuselage...
