METHODS OF AVOIDING THE YAW OF HELICOPTERS

Abstract

The purpose of this paper is a comparative analysis of the various types of helicopter rotor configurations used to avoid the yaw phenomenon of these types of aircrafts. An helicopter is a motorized aircraft whose support and movement are provided by one or more propellers rotating about vertical axes and which can land in an extremely small space or be held in the air at one point, fixed. The rotor blades rotate about a vertical axis. The rotor must develop a traction force with good efficiency to support the weight of the helicopter [1]. Helicopters can use different rotor configurations (such as a single main rotor with a tail one, tandem rotors, coaxial, side-by-side rotors), on which their aerodynamic complexity depends [2].
