After looking at many cowl inlets shapes, round, rectangle, annular, etc. etc. I'd like to know how the design on Sean D. Tuckers highly modified airplane works. His system appears to be a downdraft design with a large lower cowl outlet and two side cowl outlets. I was wondering how they came up with this design? I'm assuming it works or they would not of designed it the way it is. This design reminds me of the annular cowl design like on the Reno Racer 'Rare Bear', but that airplane has a radial engine. I'd like to hear some comments about anyone's thoughts on this design and why are there so few cowl inlets designed like this. I actually like the looks of it, maybe because it's different and not normal looking like everything else, very clean and I like the shape. Anyone interested in experimenting and changing the looks of your RV into one looking like S.D. Tuckers would have a one of a kind.
VAN and others might frown,,, but hey it's a free world. It also reminds me of how turboprop airplanes are designed with the same shape inlet for the turbine engine. After looking at the design, I could see how the stock RV cowl could be more profiled and not so blunt on the sides. No I'm not going to whack my cowl up and try it as my very small round cowling inlets are working great! I'll let someone else experiment on this one.
Bob Axsom, does this give you any ideas??? I also added the next post with the Reno racer to give you some ideas with your search for cooling drag reduction. Hope some of these ideas help.
I don't think the annular design is for racing purposes as S.D. Tuckers plane is for Aerobatics and not speed/racing.
