<P>PROBLEM TO BE SOLVED: To estimate pressure fluctuation, which is generated in a periphery associated with rotation of a propeller, with sufficient accuracy. <P>SOLUTION: A device 1 for estimating pressure fluctuation of the propeller includes an estimation part 23 for estimating pressure fluctuation of the propeller in an actual machine corresponding to pressure fluctuation data of the propeller acquired by a model test, by using data correlation information between actual machine measurement and the model test generated based on pressure fluctuation data of the propeller acquired by the actual machine measurement in the past and on pressure fluctuation data of the propeller acquired by the model test in the past. <P>COPYRIGHT: (C)2010,JPO&INPIT |
