I need you guys to explain something to me. On one hand for any object moving through the liquid ,shape is very important to reduce drag. we know that shape of the front part of this object is equally important as shape of the back side.
On other hand I am hearing this explanation that airflow on the back side of abruptly shaped object will form turbulent Triangle that will work like a bearing and this void will be naturally filled. So, we should stop worrying about building anything for this area?
I believe Peter Garrison at one point was telling me that all this fancy looking Spinners that you guys using on canards complete nonsense.
I also see how they shape fuselage on icon A5 right before propeller. They must have the same logic as far as airflow concern.
when we standing on the bridge and looking down we can see how water is moving around concrete columns. You can clearly see still water forming that kind of area that’s really not moving at all and acting like filler.
so, do I see it correctly? In certain area like prop spinner for pusher or backside of fuselage after body doesn’t need to be perfect?
