The phenomenon of dynamic stall
TL;DR: In this paper, the general features of dynamic stall on oscillating airfoils are explained in terms of the vortex shedding phenomenon, and the important differences between static stall, light dynamic stall, and deep stall are described.
Journal ArticleDOI
Computational prediction of airfoil dynamic stall
TL;DR: In this paper, the authors present the major approaches and results obtained in recent years and to point out existing deficiencies and possibilities for improvements for the prediction of dynamic stall in aerodynamic bodies such as airfoils and wings.
Book
Bramwell's Helicopter Dynamics
TL;DR: The second edition of Helicopter Dynamics by A.R. Bramwell as mentioned in this paper provides a detailed summary of helicopter aerodynamics, stability, control, structural dynamics, vibration, and aeroelastic and aeromechanical stability.
Rotorcraft Aerodynamics Models for a Comprehensive Analysis
TL;DR: In this paper, a force balance method for calculating section loads of a bearingless rotor rotor was proposed, and the results were compared with the results from a full-scale wind tunnel test.

Dynamic Stall in Pitching Airfoils: Aerodynamic Damping and Compressibility Effects
Thomas Corke,Flint O. Thomas +1 more
TL;DR: The topic is technologically important owing to the desire to develop next-generation rotorcraft that employ adaptive rotor dynamic stall control and large-eddy simulation could be a viable approach although it remains computationally intensive.

An investigation of full-scale helicopter rotors at high advance ratios and advancing tip Mach numbers
TL;DR: Tabulated performance data of full-scale rotary wings at high advance ratios and advancing tip Mach numbers based on wind tunnel tests are presented in this article, where the authors show that rotary wing performance is comparable to that of a single-rotor aircraft.
ReportDOI
Two-dimensional tests of airfoils oscillating near stall. volume ii: data report
Lewis Gray,Jann Liiva +1 more
TL;DR: In this article, the authors present a discussion of the test facility, models, and data gathering and reduction system used in the tests of oscillating airfoils, and actual computer data that resulted from the wind tunnel tests of the airfoILS.
ReportDOI
Two-dimensional wind tunnel tests of an h-34 main rotor airfoil section
TL;DR: In this article, a Sikorsky H-34 main rotor production blade was tested in the two-dimensional channel of the United Aircraft Corporation 8 foot wind tunnel at Mach Numbers from 0.30 to 0.80.
