Shepard Test Stand Preliminary Design v1.0

This document has been relinked to the Preliminary Design document here as part of our versioning system update.

Introduction

The preliminary design discussion is broken down into two parts in the forums.

  1. Mechanical systems
  2. Data Acquisition (DAQ) Systems

Most of this preliminary design work was done via Google+ Hangout. The meeting minutes from those hangouts will be distilled down into a form suitable for this document, but in the meantime you can find links to the raw meeting minutes below. You will most likely need to request permission to view the document.

  1. Mechanical Hangout Minutes
  2. Data Acquisition Hangout Minutes
