L‘Garde Programs - SSP Truss
Space Solar Power Truss
Objective: design, build and test a representative inflatable rigidifiable truss column for space solar power photovoltaic arrays.
The goals are:
- Low mass
- Low packaging volume
- Scalable
- Robust deployment
Here are some of the specifications of the truss test article:
