The stability of the two-dimensional air-filled cavity is discussed in the current study. The experimental results of two types of air lubrication hull bottom are provided to discuss the factors that affect the resistance performance of the air lubrication ships. The optimal air chamber height and the best speed range are recommended for the inland air lubrication barge based on the analysis of the experimental data. Some new suggestions are also proposed to provide reference for the development of the new inland air lubrication ship.

China Association of the National Shipbuilding Industry (CANSI) has issued a group standard “Marine propeller with hollow structure”, which is a unique propeller product standard with the innovative blade structure design and the weld assembly process. It introduces the technical background, the development at home and abroad, the contents and the process of the standard, as well as the standardized research results.
