ALL the theories relating to the nature of the airflow through a helicopter rotor which have been reviewed in the first three parts of this paper relate to vertical velocities only; that is, to the downwards acceleration of the air whereby rotor thrust is generated. But since a practical rotor blade also experiences in-plane forces it is evident that in-plane movements of the air in the slipstream must also occur. In point of fact the slipstream rotation behind the propeller of a single engined aeroplane of conventional design is an important factor in its design, particularly when considering take-off conditions.
