Please tell us a bit about your UAV interest

I focused on UAV propulsion in my education as an aeronautical engineer, which led to now doing personal projects in building and experimenting with UAVs.

"Arnie, 
As you say, it varies greatly depending on exactly what your setup is. On an aerodynamically efficient setup the power consumption for equivalent thrust would vary by a small amount, perhaps 1-2%. An inefficient setup would yield much larger…"

"The air above the prop is static at a distance, but the frames are often built very close to the propellor disk meaning that the inflow speed at the frame is almost that at the propeller disk. So the effect on power consumption and thrust is still…"

Chris D commented on Gary McCray's blog post Some MultiCopter Design Thoughts.
"Gary, I've done significant testing on prop blockage both experimentally and computationally. I tested fuselage interference on fixed wing platforms, but it's essentially the same issue as frame interference on a multirotor. My results showed that…"
