| 内容記述 | In order to calculate the critical speed of a propeller shaft, it is necessary to know the accurate values of the added mass and the added moment of inertia of a marine propeller. When the principal specifications of a propeller are given, the values of the added mass and the added moment of inertia can be calculated by a two-dimensional theory. However, in practice, a three-dimensional correction is necessary for the value obtained through a two-dimensional theory because the three-dimensional influence exerted on a propeller is great. This study aims to evaluate accurately the added effect of water on a propller. The authors defined that the coefficient of the three-dimensional correction JT is the ratio of the three-dimensional lift coefficient to the two-dimensional lift coefficient. The former is obtained through the lifting line theory. The latter is given by the KUTTA-JOUKOWSKI condition. In order to confirm the effect of Jr for the added polar moment of inertia of the propellers under torsional vibration, the experiments were carried out using two propellers each with a different aspect ratio. As a result, the calculated values of the added polar moment of inertia obtained from the two-dimensional oscillating airfoil theory became almost equal to the experimental values by using the three-dimensional coefficient JT. Therefore, it can be understood that the three-dimensional coefficient Jr is very effective for calculating the added polar moment of inertia. | |||||
