[0002] The cross-medium flying submarine is an aircraft capable of underwater and air movement, which can alternately navigate for a long time and freely cross the water-air interface. It has great development potential in the professional technical fields of military reconnaissance, underwater exploration and emergency rescue.

[0003] The cross-medium flying submarine on the market, such as patent No. 202410213292.0, uses a connecting rod to drive a flat wing to rotate around the mounting pillar to expand and fold. The flat and folded wing can only realize simple expansion / folding action, and cannot dynamically adjust the wing lateral angle according to the flight attitude, resulting in low air turning efficiency. At the same time, there is a large gap in the internal space of the fuselage, which can easily affect the dynamic characteristics and lose part of the kinetic energy during high-speed travel.

[0004] Therefore, the medium transition process of the cross-medium flying submarine is very critical. Different medium transition methods have different requirements for the control method, propulsion technology and even the shape design of the flying submarine, but there are still technical challenges.

[0013] As preferred, a limiting structure is further arranged on the rotating seat to ensure the universal coupling switches between the unfolded and folded states.

[0014] As preferred, the aileron is controlled to swing up and down by a rudder to control the maneuvering action of the flying submarine in the air.

[0015] As preferred, the telescopic double hydrofoil unit comprises a first connecting strut, a second connecting strut, a connecting plate and a streamlined hydrofoil.

[0016] The first connecting strut is connected with the connecting plate and the streamlined hydrofoils symmetrically arranged on both sides of the connecting plate to form the first hydrofoil.

[0017] The second connecting strut is connected with the connecting plate and the streamlined hydrofoils symmetrically arranged on both sides of the connecting plate to form the second hydrofoil.

[0018] The water inlet is arranged at the bottom of the streamlined hydrofoil in the first hydrofoil and is in communication with the water storage tank.

[0019] As preferred, a driving element is arranged inside the carrier body to drive the extension and contraction of the first connecting strut and the second connecting strut.

[0024] As preferred, the hydraulic boosting unit further comprises a water pump in communication with the first hydrofoil and a gas resistance valve for controlling the gas flow rate.

[0026] Preferably, the retractable wing unit, the retractable dual hydrofoil unit, the hydro-aerodynamic unit, and the hydro-boost unit are all encapsulated and waterproofed.

[0027] This utility model provides a hydrofoil-equipped cross-medium flying submersible, comprising: a flying submersible body, a side-retractable wing unit, a retractable dual hydrofoil unit, a hydro-aerodynamic unit, and a hydro-pump unit. Utilizing the stable deceleration function of the dual hydrofoils and the water storage in the water tank within the hydro-pump unit, the flying submersible can quickly decelerate and enter the water, completing the cross-medium transition from air to water in a short and stable time. During the cross-medium water exit process, the cooperation between the gas cylinder and the water tank in the hydro-pump unit propels the submersible out of the water in a manner similar to a flying squid's jet propulsion, enabling the flying submersible to quickly complete the cross-medium transition from water to air. During air navigation, the universal joint structure allows the side-retractable wing to unfold, facilitating flight control and stability. During underwater navigation, the universal joint structure allows the side-retractable wing to retract tightly to both sides of the flying submersible body, reducing drag during underwater navigation.
