Abstract
A turbine blade having an extensible tail is described. The extensible tail is selectively positionable during engine operation, enabling fine-tuning for maximum power and efficiency during engine operation. During periods of operation exhibiting low Reynolds number flows, the extensible tail is projected out from the trailing edge of the turbine blade, into the gas path. As Reynolds number flows increase, the extensible tail is retracted back into the turbine blade, maximizing turbine engine efficiency.
