Dynamic stall has been a technical challenge and a fluid dynamical subject of interest for
more than fifty years; but in the last decade significant advances have been made in the …

This study aims to investigate the effect of forward speeds on the flow structure and dynamic
stall events of a single rotating blade with pitching motion. Two flight speeds are examined …

The study presents an optimized pressure-sensitive paint (PSP) measurement system that
was applied to investigate unsteady surface pressures on recently developed double-swept …

Recently, fluid–structure coupling simulations of helicopter rotors in high-thrust forward flight
suggested that dynamic stall might be triggered by the blade–vortex interaction. However …

Experimental investigations of three-dimensional dynamic stall on a four-bladed Mach-
scaled semielastic rotor with an innovative double-swept rotor blade planform are …

Recently aeroelastic simulations of rotors in dynamic stall conditions based on a weak
coupling between CFD (Computational Fluid Dynamics) and CA (Comprehensive Analysis) …

Dynamic stall has been studied for more than fifty years; in the last decade significant
advances have been accomplished in the understanding, prediction, modeling and control …

传统直升机气动设计较多依赖升力线理论, 涡流理论等工程分析方法, 高性能计算使采用CFD

Le décrochage dynamique se produit sur les rotors d'hélicoptère fortement chargés ou à
grande vitesse d'avancement. Il engendre des efforts dynamiques importants et d'intenses …

In this study, numerical simulations are used to investigate the dynamic stall phenomenon at
two advance ratios, μ= 0.3 and μ= 0.35, on a single blade with cyclic pitching motion. To …
