Last Week
• AFRL CDR and Reports!!!!!!!!!!!– Structural feedback
• Excellent work –– “Consider putting the battery box on the bottom, not the
top. If you put it on top, you make the structure do something you don’t want it to do.”
– “Don’t need to use so many nodes.” • Chasing the convergence• More sims in progress
– Thermal feedback• “In general, the analysis lines up ‘very well’ with others
seen before.” • Use SINDA/Thermal Desktop• Radio RF powers loss vs. thermal power loss• We have many nodes.

Next Week
• General– Prepare for FDR
• Structural– Create a structural analysis handbook for subsequent
Nanosat teams– Report revisions
• Thermal– Create a thermal analysis handbook for subsequent
Nanosat Teams– Use student version of ANSYS with reduced nodes– Report revisions

Outstanding IssuesGeneral
-ANSYS license expires 30 April 2008-update reports as necessary-exit interviews
Structural-continue to run sims and make structural modifications to ensure the satellite meets all AFRL structural requirements-all structural requirements now fulfilled
Thermal-cold case sims -take into account thermal control issues since ANSYS license expires

Future Work
•Possible satellite attitude effects on temperature extremes
•Thermal control methods (fins, coatings, etc)
•Component relocations
•Mesh refinement for convergence verification
