This resulted out of a curiosity experiment where I wanted to figure out if the 2022 SAE AERO Micro Class competition would have benefited from a variable pitch propeller system. As shown in the scoring equation, the flight score is inversely correlated to flight time (to 300 ft), so any improvements to speed would have a compounding benefit on score. To provide some context, the 2022 TAMU SAE Micro Class airplane had a 300 ft time of ~13 sec. Decreasing that flight time to 10 sec would result in a 30% larger flight score, which is quite significant.

So, I decided to try making a micro scale variable pitch system to see how it may increase thrust - the idea being, the pitch of the propellor can be continuously adjusted to the most optimum angle. 

This prototype is fully designed and constructed, but has yet to be tested because I have taken a semester off of school for an internship. Once I return, I intend to put it in the wind tunnel to determine how it performs in 0-30 mph airspeed.
