Re: Preliminary analysis of aerodynamics of sparrow strainers (or not)
Hi Michael,

Not much time to fully absorb all the items you bring up, but let me hit a couple. Airfoil dimensions were normalized for my multifoil model representation including with the Eppler main wing so absolute chord equal to 1.0 (100%) is reduced for dimensional convenience to accommodate both airfoils and total lift calls. This changes Reynolds numbers slightly as well. So I am just comparing apples to apples within my personal modeling framework. The difference in Angle of LS1 in the QAC plans relative to the UIUC database was noted and discussed (in addition to actual wind tunnel data) in part 1 of the Q2xx modeling paper that I did. Have a look at that summary and see if it it squares up the discrepancy you observed. I am headed out of town for a week or so and I will see if I can wrap my head around the other points you make as time permits. Thanks for your inputs. Cheers, Jay
