For the purpose of the elucidation of resonance between vibrations of the propeller shaft and the propeller blade, this paper presents the measurements and calculations of the flexural natural frequency of the full scale propeller blade in .air and in water, the vibratory stress due to the resonance and the life of the fatigue failure. It is shown that there is a fair possibility for the high vibratory stress of about 60 N/mm2 to affect the early blade failure., 長崎大学工学部研究報告, 24(43), pp.135-140; 1994}, pages = {135--140}, title = {プロペラ翼の折損に及ぼす主要因子の解明(第2報:プロペラ軸とプロペラ翼の共振の影響)}, volume = {24}, year = {1994} }
