- Note (General)
- This paper presents the torsional stress analysis of hollow fan blades by the Finite Element Method. The fans are considered to be double circular-arc blades, hollowed 30% and twisted by a component of the centrifugal force at the rated revolution. There are 0-7 webs inserted in the hollow section. The following became clear after stress and rigidity analysis of the hollow blades. 1)Making the fan blade hollow by 30% increases the torsional rigidity per cross section by 20-24%, and maximum shear stress by 17-27%. 2)The number and location of webs don't have a considerable effect on torsional rigidity. 3)There is an optimum web location for torsional rigidity, where the shear strain in webs is maximum. 4)Shear flows branch away to webs, and stress consentrations decrease.資料番号: NALTR0533000レポート番号: NAL TR-533
