Again, its all in the question. two scenarios for a ducted prop in hover:
- inlet guide vanes close to the prop to control the angle of attack
- just a prop with a variable pitch mechanism.
obviously, the first option is mechanically simpler, as we are not dealing with a rotating component. so my question is more specifically about the aerodynamic side of things. how accurate/responsive are guide vanes at controlling AoA? how draggy are they?
thx in advance!
