loads engineā€ makes it possible for the turbine designer to explore more options in
a shorter period of time and quickly adapt the overall value analysis program for
emergent component technology assessment.
Today, FLEX5 has as many as 34 degrees of freedom modelled for the upwind
three-bladed WT. There is a great deal of data available from the normal solution
results, but there is a smaller subset of this data that has the greatest impact on the
initial sizing of turbine components. Using FLEX5 naming conventions, Fig. 11
shows these primary forces and moments and the components they are related to
and act upon.
4.2.5 Load calculations
To gain an appreciation for the level of extreme loads developed in a WT,
and how they change with turbine size, a 10-turbine analysis group of today's
industry average technology was undertaken. These turbine design cases are
