Experimental and Design, CFD, Modal analysis of E 387 Helicopter Blade

Abstract

Now a days it is observed that weight parameter is a specific issue for many companies for better efficiency of any product. So, in resent a specific profile of E 387 light weight helicopter blade is designed. Due to composite material of carbon epoxy it is light in weight but also high strength carrying blade. In present research, design using standard airfoil tool website is presented along with CFD simulation is been performed to know lift carrying capacity and also modal analysis is been performed using ANSYS software. Similarly, validation is concluded with FFT technique in which results obtained through modal analysis with mode shape and respective natural frequency are compared.
