In the 3 blade prop area, you have broken up the air with the previous prop a bit more so, the thicker the air, the more effiecient the prop, it's kind of like putting 2 motors and props operating independantly just behind each other, the rear prop only has the left overs from the front one -----
That does not actually happen in flight & only occurs under particular conditions on a test bench.
Can you elaborate upon this, I'm in the mindset of basic physics here, you are displacing the volume of molecules outward, causing them to be less dense within the traveling path of the blade, now within it's absence they equalize out due to the natural air pressure, then do the same yet again on the returning cut into the air, I'd think the longer the interval in between cutting the air and allowing it to reintigrate back into it's orignal configuration the more adventagous. I'm sure after enough velocity of the actual prop assembly moving foward, the volume of air molecules pushing into the field make up for this effect.
