Abstract

This report presents analysis of an isolated blade of NAL designed windmill SAMIRA. The blade has an aluminium skin mounted on a mild steel spar and frame work. The blade has a full span loading edge regulating flap. The flap is connected to the spar by four sets of spring plates and a shock absorber to damp the flapping vibrations. A single blade is modelled using a preprocesser FEMGEN and analysed using a finite element analysis package called ASKA. The static analysis is carried out with pressure loading equivalent to a normal load calculated at a velocity of 50 m/sec. The dynamic analysis is carried out to get the modes and modeshapes of the blade. The validity of the model is established by an experimental study.
