The UTARA is an innovation that increases the thrust of an aircraft propeller.

Research ways to make an aircraft propeller more energy efficient. 

 Developed the UTARA (Universal Thrust Autorotation Augmenter), a textured surface, when placed on the back of an aircraft propeller with specific positioning, will increase its thrust.  The energy saving result;  to achieve the same thrust with less RPM means less fuel burned, less fuel burned is an environmental win.
