The purpose of this document is to introduce the localized development procedure for socket head cap screw used for satellite application. For localized development and verification of socket head cap screws, manufacturing process was composed of head forming, heat treatment, rolling process and surface treatment to meet aerospace hardware requirements based on MIL-B-7838, ECSS-Q-70-46A and KS W 8168 aerospace specification. In order to verify the quality and performance of localized screw, several kinds of qualification tests are successfully completed. By comparing the quality and performance for the localized screws and the same size oversea-procured screws, we can sure that localized socket head cap screws have good quality performance enough to use for aerospace application.

The propellant mixer for charging of solid rocket motors is one of the most important equipments. For the propellant mixer is export control item, it's hard to purchase it directly from abroad. The Mixer was developed locally to overcome export control which precludes us from import. This paper includes the introduction for general mixers and the process of mixer development progressed by LIGNex1. Finally, The mixer is verified the performance using measurements of clearance between blade-blade and blade-bowl and flow simulation with ADINA.
