Abstract
This Paper presents a linear model for a square solar sail spacecraft containing four pretensioned triangular sails supported by four flexible diagonal booms. The structural dynamics of the stretched sails and diagonal booms is explored by using a two-stage model including a static finite element or analytic model to solve for the sails in-plane stresses due to prestretching and a dynamic finite element model to calculate the in- and out-of-plane deflections of the interconnected sails and booms. The dynamic finite element model takes into account the effect of in-plane stresses, which are calculated by the static finite element or analytic model. Once the structural dynamic model is established, different modal cost analyses are used to evaluate and rank elastic modes of the solar sail. Two attitude controllers are developed for the solar sail, and the controller/structure interactions are studied using the linear model and considering an attitude maneuver.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
