Abstract

Several theoretical studies have been addressed to the evaluation of natural frequencies of rotating structural elements as space frames, windmill rotors, aircraft propeller, etc. This paper presents the results of the natural frequencies calculation for an airscrew through finite element method. The same numerical method has been used to simulate a laboratory test for inducing the stiffening effect by means of tensile loads. The advantages and the accuracy of such a test are also reported.
