Our Naval Warships and naval architecture have leaped on a level with the best of the world. Also, technology of underwater intimidatory forces has improved. A acoustic stealth warship of the newest type is developing in order to insure survivability of the warship from the underwater threat of an enemy. Advanced countries give impetus to the researches for the need core technology. In special, Underwater Radiated Noise(URN) reduction and control are an important problem in the performance of underwater acoustic stealth systems. The URN level is decreased for submarines warships. This paper analyses the design characteristics of the warship propeller and derives the core technology as lower noise design, propeller design methods. In order to reduce the URN, it suggested the systematic plan of the mid and long term core technology and the experimental analysis method using the warships design ability, modeling & simulation test.
Therefore, this paper understand the domestic warships lower noise propeller design technology level and the dominant noise source of the underwater propeller is analyzed, which will provide a basis for proper noise control strategies. It was suggested that the roles of research institutes in naval warship core technologies should extended for the future.
