Abstract
The primary sources of drag for a straight-bladed vertical axis wind turbine (SB-VAWT) are the blades which are also responsible for generating lift. The supporting struts of a SB-VAWT are also responsible for generating additional parasitic drag which reduces the overall power output. It is one of the major disadvantages of the SB-VAWTs as the loss of power due to its effect is proportional to the cube of tip speed ratio. The aim of this paper is to present an alternative airfoil for the shape of the supporting struts of smaller-capacity fixed-pitch SB-VAWTs to reduce the parasitic drag losses. A new airfoil "MI-STRUT1" has been designed which performs better than another available streamlined strut, namely E862, especially at low RN range. Based on the finding it has been proposed that MI-STRUT1 can be considered as a potential candidate for the profile of supporting struts of SB-VAWT for better performance.

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
