Abstract
SAMIRA is a three bladed water pumping windmill driving a 2 Hp centrifugal pump. The blades have full span regulation. In the existing design Samira has a single level guyed tower. To meet a specific requirement from a particular area, it was decided to substitute the guyed tower by a free standing tower. This report presents a method and calculations carried out for designing the free standing tower. The preliminary design is carried out using graphic statics and the dimensions of tower members obtained are then refined using a more versatile finite element package ASKA. Further, the effect of different base widths on the cost of the tower is examined. The static analysis of the tower with refined tower members is also presented.
