Summary
Blade Element Theory
is a method for
Analyzing the behavior
and
Performance of rotating machines
like
Propellers and turbines
by
Dividing their blades
into
Small elements
, making
Aerodynamic calculations
for each element, and summarizing the results. This theory allows for the approximation of
Forces and moments
to
Design more efficient blades
by considering
Variables such as lift and drag
at numerous
Sections along the blade's length
.
