HelioWAVE is a dual–axis tracking heliostat consisting of a steel U–channel chassis that structurally supports the reflecting surfaces. The idea for the heliostat is to optimize cost and design parts to improve manufacturability which was decided based on our diverse backgrounds and passions, including strengths in manufacturing, control theory, and computer aided design. We believe this design will not only achieve this concept, but also revolutionize the industry. Our main support structure for the heliostat, the chassis, uses varying steel U–channels, fasteners, and welded joints for easy manufacturing and cost effectiveness. This configuration serves as an aerodynamic frame that can withstand Las Vegas winds due to its simple alignment. Each reflecting surface is provided with its own motor to allow for a dual independent axis tracking system that rotates the connecting shafts of each reflecting surface. This will allow each surface to rotate horizontally about its center at the necessary independent angle towards the receiver tower. The reflecting surface design features a very compact configuration, which allows for optimal concentrated focal thermal output while also minimizing the size of the heliostat to allow for more space in the surrounding solar plant field. In terms of vertical rotation about the azimuth, the heliostat will include a rotating shaft along the steel chassis frame, powered by a motor and gear configuration which will angle all four reflecting surfaces synchronously. The use of only five motors will drive down cost and enhance power consumption, ultimately increasing our heliostat’s design life.
