1. Steven Izzo 2/21/2008 Structures Buckling Support Design Code with help from Brandon White
AAE 450 Spring 2008

2. Outputs Method Mass and cost of rings.
New tank thickness if necessary.
Method
For final design check.
Same buckling vs. applied stress from previous.
Titanium rings for minimum mass and volume.
Minimum ring size, then use cost functions.
If rings are very thin, change tank thickness instead.

3. Results Future Work Ran for test case- no rings needed yet.
Re-verify method to
use in final design.
