PROJECT DESCRIPTION Orbital ATK has commissioned this capstone team to design a low-shock payload separation system that can be built in-house at a fraction of the cost compared to what is currently on the market by their competitors. (1) Work with Orbital ATK mechanical engineers to understand the needs and desires of the delivered project. (2) Survey commercially available separation systems. (3) Develop design concepts that meet all requirements. (4) Perform trade studies to down select to a single design. (5) Manufacture a prototype. (6) Provide Orbital ATK with PDR and CDR presentations. (7) Final product will include design, analysis and manufactured prototype. October 24, 2016 Garrett Wright Orbital ATK Team A
