Unsteady aerodynamic and stall effects on helicopter rotor blade airfoil sections
6th Aerospace Sciences Meeting, 1968Oscillatory tests in pitch and in vertical translation were performed on symmetrical and cambered airfoils, at full-scale Reynolds numbers, to provide dynamic stall data for rotor blade analyses. The Mach number range applicable to the retreating side of the rotor disk was covered at frequencies up to the first bending and the first torsional natural ...

Roughness Tolerant Airfoil Design for Rotor and Propeller Applications
Proceedings of the Vertical Lift Aircraft Design and Aeromechanics Specialists Conference, San Jose, California, Jan 2026A technique for rapidly designing roughness tolerant low drag airfoils has been developed. Airfoils of varying thickness to chord ratio, ranging from 10% to 22% have been designed. A target pressure distribution is specified by the designer for a notional lift coefficient, Reynolds number, and Mach number.

Studies of the Dynamic Stall or Airfoil Profiles for Helicopter Rotors.
1979Abstract : The interaction of oscillations of the mean velocity of the relative flow with the periodic changes in angle of attack that are produced in the forward flight of helicopters on the airfoil profiles of the rotors has been investigated for the first time.
