This project provides an open source for a cable drum as part of a system designed to launch sailplanes. Other CEDE teams designed the control systems and drive. The design of the drum needed to be lightweight, weather-resistant, cheap and easy to manufacture while conforming to the sponsor’s numerical specifications. The rib-reinforced design is the result of a series of refinement of four conceptual designs and the sponsor’s reference design. We developed both shop and assembly drawings and a bill of materials that includes material and finish specifications, as well as a cutting template for necessary parts and pieces. We used ANSIS for stress calculations, and released the design with a 3-D license held by Gonzaga University.
