Abstract: An unmanned semi-submarine, including a main hull; airfoil buoyancy chambers; an antenna; a radar; a propeller; a rudder; and compartments. The airfoil buoyancy chambers include a front buoyancy chamber and a rear buoyancy chamber. The front buoyancy chamber and the rear airfoil buoyancy chamber are longitudinally distributed on the main hull. The radar and the antenna are disposed on the top end of the front buoyancy chamber. The rudder is disposed on the rear buoyancy chamber. The propeller is disposed at the tail of the main hull to drive the unmanned semi-submarine. The horizontal sections of the front buoyancy chamber and the rear buoyancy chamber are symmetrical airfoil. The compartments include a front equipment compartment, a rear equipment compartment, a control equipment compartment, a battery compartment, and a propelling compartment. The compartments are separated from one another using watertight walls.

Abstract: The present invention belongs to the field of advanced manufacturing technology and relates to one set-up and method of electrohydrodynamic jet 3D printing based on resultant effect of electric field and thermal field. This method is used to fabricate micro/nano 3D structure, under the resultant effects of electro hydrodynamic force and thermal field. First of all, the ink reaches needle orifice at a constant speed under the resultant effect of fluid field and gravity field. Then a high voltage electric field is applied between needle and substrate. And the ink is dragged to form stable micro/nano scale jet which is far smaller than the needle size using the electric field shear force generated at needle orifice. The solvent evaporation rate of ink increases combined with the radiation of thermal field at the same time. Finally, the micro/nano scale 3D structure is fabricated on substrate with the accumulation of jet layer by layer. Compared with liquid jet printing technology, this method describing in present invention owns many advantages, including wide adaptability of material and manufacturing complex micro/nano scale 3D structures.

Abstract: An unmanned surface vehicle (USV) including a main body; a slideway; and an automatic recovery unit. The slideway includes pulleys, slide rails, sleepers, end plates disposed at two sides of the sleepers, and baffle plates. The automatic recovery unit includes a buoy, a connection rod, a downhaul, an electromagnetic fixer, a winch, an upper cable, a storage box, and a recovery net. The slideway is fixed on the afterdeck of the main body and the tail end of the slideway sticks out the side boundary of the afterdeck. The baffle plates are disposed on the upper end of the end plates. The vertical height of the end plates is larger than the maximum vertical height of the pulleys and the slide rails. The baffle plates on the upper end of the end plates limit the displacement of the buoy in the vertical direction.
