Abstract
One of the most specific important problems for coaxial helicopter rot ors is to ensure an adequate clearance between upper and lower rotor b lade tips. The results of investigations made in this field are presen ted and discussed in the present paper. The results of analysis and ac tual experimental flight data are compared for steady horizontal fligh t and maneuvering flight conditions.
