USPC 244/45 is a patent technology subclass is for arrangements between airfoils or between airfoils and a fuselage.[1]

USPC 244/45A and USPC 244/45R mark a temporary division of these patents, which we are not carefully tracking here, based on advice from a specialist at the US PTO (per the discussion at Talk:USPC 244/35) It is possible that the 45As were for "compressed airflows" and the 45Rs were for all others, the residual category.
