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
- f 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.
