The present disclosure relates generally to the field of facilitating a laminar flow and sound mitigation between a wetted hull of a vessel and surrounding fluid. More specifically, the present disclosure includes methods, systems, and apparatuses to facilitate providing and sustaining a laminar flow of a fluid across a vessel. A system for sustaining laminar flow of a fluid across a vessel comprising a main control unit. The main control unit comprises one or more air compressor units configured to generate air. An integrated longitudinal air distribution assembly is secured to a wetted hull of the vessel. The distribution assembly comprises a series of air dispersal modules configured to distribute the generated air across the wetted hull of the vessel to create at least one air layer between the wetted hull of the vessel and the fluid to sustain the laminar flow of the fluid across the vessel.

A wind-water machine set is an evolving jet machine that moves the internal engine to the outside of the sleeve to work, instead of using a water jet as the main and air-jet as the auxiliary. When a ship uses multiple groups of wind-water machine set, there is a master control center for overall control and coordinated operation. Controlling the propulsion system makes the ship move forward and backward in an orderly manner. Control the surfing system to eliminate the bow water resistance and cooperate with the propulsion system. The steering control system is controlled to make the ship easy to operate the steering. Control the balance system to keep the ship balanced without swaying the roll angle. Control the draught system so that ships do not need ballast water. So that the ship can sail at super high speed, super fuel-efficient and safe.

The novel bladder systems and tie down systems set forth herein provide systems and apparatuses that mitigate or prevent damage, such as tipping over/capsizing, of a watercraft stored on shore or an aircraft secured to a ground surface during adverse wind, rising water, or storm events. Further, novel apparatuses and methods for storing a watercraft using the bladders as cushioning or holding devices when installed within a cavity, whether the cavity is created by digging a hole or building an enclosing berm, provides additional stability and security for the watercraft during adverse wind, rising water, or storm events.

This disclosure relates to a ship hull microbubble system used to reduce frictional drag on a ship hull while traveling through water. The microbubble system includes a water pump connected to an ejector which intern draws and compresses air within the ejector body. While in the ejector the compressed air becomes entrained within the pumped liquid as microbubbles creating a multiphase fluid which is then ejected at suitable pressure from the ship hull below the waterline through dedicated hull openings. The ejected air liquid multiphase fluid then creates plurality of microbubbles within the below water boundary layer reducing frictional drag generated by the hull as it travels through water. This disclosure has advantages when compared to related art through minimizing ship structure modifications, reducing wear on the ballast pump, operational autonomy from the ballast system, reducing the systems area footprint, independent control of the air injection rate, simplifying the installation through reducing existing pipework modifications and removing the need for riser pipes and additional tanks.

The present invention is a device to reduce the skin friction drag on the hull surface of a marine vehicle. The device is in a form of a channel having a wider portion facing an incoming water stream (inlet) and a narrower portion (outlet) installed over an air orifice on the hull surface, forming an array of channels. A stream of water, generated by a marine vehicle motion, enters the channels and creates a low pressure region that pulls the air into the stream of water through the air intake holes, creating a stream of air bubbles. This structure increases water flow velocity close to each air orifice, creates larger turbulent components passing through and over each channel, injects more bubbles, and avoids dispersion of air bubbles to improve the existing skin friction drag.

Disclosed herein are a method and a system for forming an air layer over a portion of an engineered surface, wherein the air layer is formed with a reduced flux and preferentially steering gas away from, or toward, a specific location by way of a hydrophobic surface, a hydrophilic surface, and/or a structured surface. Moreover, disclosed are a method and a system for recovering or separating a portion of the gas or other fluid layer.
