Embodiment Construction
[0042] On the basis of comprehensive analysis of the two drag reduction technologies of bubble injection and supercavitation gas film, the invention proposes a new drag reduction principle: resident micro-bubble drag reduction. The bubbles are not injected into the fluid boundary layer, but controlled to be stably attached to and reside on the water surface and the outer surface of the underwater vehicle. A large number of attached fine bubbles isolate most of the water-solid interface, changing the liquid-solid interface to liquid. -Air interface, so that the surface friction resistance of the vehicle during travel is significantly reduced. Combined with flexible MEMS technology, a flexible thin film structure is made, and a drag reduction skin suitable for water surface and underwater vehicle is obtained.
[0043] The following are the embodiments of the present invention, and the embodiments of the present invention are described with reference to the accompanying drawings....
