Hydrofoil equipped seaglider takeoff
A craft comprises a hull, a wing, a hydrofoil, and a control system. The wing is configured to generate upwards aero lift as air flows past the wing to facilitate wing-borne flight of the craft. The hydrofoil is configured to generate upwards hydrofoil lift during a first mode of operation as water flows past the hydrofoil to facilitate hydrofoil-borne movement of the craft through the water. While the craft is hydrofoil-borne, the control system is configured to determine the upwards aero lift generated by the wing. The control system is further configured to control the hydrofoil to generate downwards hydrofoil lift to counteract the upwards aero lift generated by the wing that maintains the hydrofoil at least partially submerged in the water while the determined upwards aero lift is below a threshold lift.

Air-entrapping closed-loop system for lower air cushion bin of flat-bottomed ship and technology for changing balloon into ship bottom bin
The invention discloses a novel flat-bottomed ship, which is characterized in that a downward air cushion bin is arranged under the ship bottom, the air cushion bin is filled with air, the air cushion is called an air cushion, the direct contact between the ship bottom and water is isolated by the air cushion, the air cushion is like a maglev train which floats in the air to walk, and the resistance is very small. However, the two sides of the wet ship bottom are still soaked in water, and the resistance is still large. If the air cushion bins are inflated, the ship body can be lifted, namely the contact area between the two sides of the ship and water can be reduced, namely, the resistance is reduced. When the inflation air pressure is increased to a certain degree, the air cushion bin cannot wrap the air, and the air leaks. If the leaked gas is collected and sent back to the air compressor, a closed loop is formed, and the difference between the air pressure of the collected leaked gas and the air pressure sent out by the pressure sink is the work to be done by the pressure sink. The invention provides a collection method. Due to the fact that leakage is reduced, the power of the pressure sink machine is small, the air cushion bin is slowly filled with small power at ordinary times, and air is supplemented when the ship is opened. In addition, a ship bottom bin is sealed, air in the ship bottom bin is pumped out, and a big balloon is formed. Therefore, the loading capacity of the ship is improved, and the draft of the ship is shallow. In general, the invention is energy-saving and speed-increasing.
