Where is the best centre of gravity for planes like the Berkut 360?
I cannot tell you the exact location or the locus of the CoG for the current aircraft but I can provide you a method that you can use to find the appropriate location for the aircraft to be statically …

Are canards useful for ultra low flying aircraft?
This highly depends on the overall conceptual design of the aircraft and there is no ideal configuration for any flight mission profile, except if you have very specific design constraints that will f …

How can leading edge separation bubbles be prevented?
The velocity-jump at $\simeq 0.5c$ is due to a laminar separation bubble.
But you ask two different things here:
Prevent leading edge separation
A leading edge separation may happen as the lami …

How does the A350 variable camber system decrease drag?
Briefly speaking, there at two types of drag: profile drag and induced drag. Profile drag can be said to be composed of viscous drag and shock-wave drag (these two often interact). Induced drag is a r …

Does zero-lift angle of attack depend on Reynolds number?
The aerodynamic coefficients $c_l,c_d,c_m$ are in general functions of the angle of attack $\alpha$, Reynolds $Re$ and Mach number $Ma$. For your experiments, since you are operating in a very low $R …
