- Which modes are dominant now?
- Does coma reduction correlate with lateral support changes?
3. Comparison with V15 NSGA-II
Analysis pending
- How does best trajectory result compare to V15 Pareto front?
- Is trajectory method competitive?
- What insights does trajectory provide that discrete WFE doesn't?
4. Lateral vs Axial Sensitivity
Analysis pending
- Which parameters affect which modes?
- Are lateral supports primarily controlling coma (as predicted)?
- Are axial supports (whiffle tree) controlling spherical?
Recommendations
Next Steps
Analysis pending - based on results, suggest:
- Whether to proceed with SAT trajectory optimization
- Which modes need further attention
- Whether to refine parameter bounds
- Additional angles to include in trajectory
Parameter Bounds Refinement
Analysis pending
- Did any parameters hit bounds?
- Should ranges be expanded or narrowed?
Future Studies
Analysis pending
- SAT3_Trajectory_SAT (100 FEA + 10K surrogate)
- Multi-objective trajectory (optimize modes separately)
- Trajectory + mass trade-off
