  1. Brandon AndersonWeek 3: February 1st, 2007 Structures GroupTaxi Capsule, Electric Propulsion System

  2. Electric Propulsion System • Truss • Supports EP system and various vehicles being transported • 4 segments • Standard 1.5x Safety Factor • 2.5g Max Load • Cube, width = 2m • Al 7075-T6 • Payloads based on Dan Maguire’s calculations

  3. EP Continued • How to lower this size • Staged Mars Launch Vehicle will reduce payload • 2-axis Trusses • Material Choice AlLi Alloy shows advantage in other structures

  4. Backup Slides

  5. Backup Slides

  6. Equations • Buckling Yield

  7. Dimensions Each Truss Contains 4 Sections, 1-4 are for near truss, 5-8 from far truss. Designed assuming payloads will be max 8.7m diameter. Allows for minimum 1.3m between payloads. Cross bars to connect to vertical sections are .09m radius.

  8. Mass and Volume This is for each side.
