This project was made in collaboration with Dr Masters for the ESSIE wind tunnel at the University of Florida. The design goal was to create a mechanism that translates a roughness element upward while rotating the element. The elements cross sectional area is used to create a turbulent boundary layer. The mechanism is able to hold a 1 degree rotational tolerance with the translated height being a strict function of the rotation. As the element spins upward the cross section has the same effective area for every 90 degrees which gives four heights to choose from for every period of rotation.
