Wallops 6U Deployer Improvements

Completed Technology Project

Project Introduction

The current Wallops Flight Facility (WFF) 6U deployer has yielded innovation in the way CubeSat style satellites are being constrained. The concept has been proven through testing and is being considered in GSFC proposals. However, the design is in need of improvement to bring it to a level of performance and reliability that would put it in a class of its own. This effort looks to incorporate the needed improvements into the design and demonstrate them through testing.

The WFF 6U deployer will be improved in 11 key areas:   1. Mass & Joint Reduction 2. Two Stage Release 3. Door Orientation 4. Satellite Preload System Improvement 5. Sounding Rocket Fitment 6. Quick Disconnect 7. Launch Vehicle Interface Update 8. Deployment Verification System 9. Shear Pin Preload System Improvement 10. Deployment Spring Interface 11. Nitrogen Purge System Once the improvements have been incorporated into the design, detailed structural analysis will be completed to ensure survival under predicted environmental loading conditions.  A qualification unit of the improved design will be manufactured and undergo functional, vibration, and thermal testing.
