Evil Twin - thx for sharing us this interresting video
crab - the tial rotor vortex ring state, is similar to the main rotor vortex ring state; if we have a left cross wind (anti-clockwise), the induced flow of the tail rotor is encountered by the left cross wind which reduces the induced flow and increases the angle of attack to reach the critical angle and the blade looses its efficiency; it's similar to the main rotor vortex ring state(settling with power). But this is not our objective of discussion, this is a fact, but between the two evils: the left cross wind(resulting T/R VRS) and the right cross wind(resulting reduction of power) which evil do you choose?
Your thoughts guys ?
