Micro-bubble drag reduction technology is a method of energy-saving that has been applied on high-speed air cavity crafts effectively. A The high resistance reduction obtained by micro-bubble resistance transition-class ship always has large length-breadth ratio and a certain reduction attracted many researchers focusing on this topic. Murai Y, deadrise angle because of the consideration of hydrodynamic Fukuda H, Shi Y, et al. (2007) measured wall shear stress and bubble performance, so the application of the micro-bubble drag reduction on image synchronously, they used time resolution measurement method this kind of ship is more complex and attractive. A high-speed and discovered the local surface frictional resistance and the local transition-class passenger ship (with the volume Froude number about porosity negatively correlated. Jang J, AHN J, Kim, et al.(2001) did a 2, with high length-breadth ratio and big deadrise angle) is tested series of experiments on three small geometrically similar high speed numerically and experimentally, the effects of air injection pattern, launches in towing tank, and discovered that the energy conservation, position and size of the air injection device on the micro-bubble drag cavitations area and the needed airflow rate related to the effective reduction rate are discussed, methods to determine the position and wetted surface directly are restricted by the Froude number. Takahashi dimensions of the air injection device for this kind of transition-class et al. (2000) did experiments on plane plate, and researched about the ship are studied. The effects of width of the air injection slot, number scale effect and the application of the micro bubbles on the ship. of air injection outlet, air injection amount, ship velocity, stern flap angles and navigation state on bubble distribution and resistance Until now, micro-bubble drag reduction technology is mainly applied reduction are obtained, influence of spray deflectors and shape of ship on flat-bottom ships and high-speed boats. It is because that these kinds stern on bubble control and resistance reduction are found.
