Abstract
The low pressure steam turbine blade rows have a history of stress failure. They suffer from tensile and bending stresses partly due to the centrifugal force as a result of high rotational speeds and partly due to high pressure, temperature and speed steam loading. The centrifugal force is one of the problems that face the designers of turbine blades especially the long ones. The primary objective of design is to deeply understand the needs of customers to define product function and utility, to satisfy the user’s request and indicators and to guide the product designer accordingly with the value engineering thought. The way of realizing product’s function must be firstly considered, and at the same time, the cost. The statistical result indicates that about 70-80% of the product cost has been already decided as designing, hence, this topic approaches towards reducing the cost at design phase by considering optimum parameters like FOS, & Life
