It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
This paper presents a comparative study of five propeller configurations, each with four blades. Two configurations feature all blades on a single plane: one with even spacing and another with uneven spacing of 30°. The remaining three configurations have blades separated axially by 0.065D.Within the uneven setups, two propellers are examined where the forward blades either lead or lag the downstream blades. Computational fluid dynamics was utilized to generate
