Abstract
Dynamic stall delay of flow over airfoils rapidly pitching past the static stall angle has been
studied by many scientists. However, the effect of compressibility on this dynamic stall behavior has been
less comprehensively studied. This review presents a detailed assessment of research performed on this
subject, including a historical review of work performed on both aircraft and helicopters, and offers insight
into the impact of compressibility on the complex aerodynamic phenomenon known as dynamic stall. It
also documents the major effect that compressibility can have on dynamic stall events, and the complete
change of physics of the stall process that can occur as free-stream Mach number is increased.
