Mechanical Engineering Winch Drum Design & Analysis, ME13 Anthony Armstrong Dane Goodman Mitchell Heesacker Samuel Oyen Advisor: Robert Stiger Sponsor: WinchEngineer Group Liaison: George Moore 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.
Boiling Cold Plates, ME14 John Sousa Greg Hutchinson Ryan Kellogg Obadiah Schwartzel Advisor: Robert Stiger Sponsor: Parker Aerospace Liaison: Andrew Johnston
The project with Parker Aerospace is the development of an effective cooling system for high heat load electronics. Specifically, there is a difficulty in distributing a two-phase fluid evenly across an array of channels. The boiling fluid needs to be distributed evenly in terms of quality and mass flow rate. This distribution is important because it is directly correlated to the performance of the cooling system. We addressed this problem by designing and building a refrigerant test loop capable of testing different distribution devices, which were assessed on the basis of a temperature gradient across a set of heated channels. Parker will be able to use this project for current and future designing of thermal management systems. Gonzaga Design Exposition Day 2014
