Preliminary Design Review
Wind Turbine with Gearbox
Team G
Nick Koerner (Lead), Meteb Almutairi, Chris Batsch, Mike Villamar
System Design
Overview
● Convert mechanical energy to electrical energy while
maintaining high efficiency
● Maintain control to obtain maximum power output
o Maintain a constant 5 V supply
● Durability
o Avoid components maximum ratings
● Upon completion of assembled project, data can be
gathered to produce the power curve performance
