Theoretical analysis and experimental researches regarding the asymmetrical fluid flow applied in aeronautics

Abstract

The current paper has been written in order to find the best solutions to replace the antitorque rotor of single-rotor helicopters, with removal of its disadvantages through the Coandə Effect. This would significantly increase the flight performance. The research mainly aims at obtaining a controlled lateral force due to Coandə flows through the tail boom, a force which would be useful for the stabilization needed because of the lifting rotor during the flight of single-rotor helicopters.
