摘要
A method for inhibiting dynamic stall of an airfoil (10) having a leading edge and a trailing edge (18) that define a chord therebetween, as the airfoil executes a pitching motion at a frequency of airfoil oscillation, comprising a step selected from 385 כ" ו באדר התשס" ב - March 10, 2002 the group consisting of: (a) causing a fluid to flow through at least one location (33) on the airfoil within about one quarter of the chord from the leading edge, said flow being with a zero net mass flux; (b) causing a fluid to flow through at least one location on the airfoil within about one quarter of the chord from the leading edge, said flow being with a non-zero net mass flux and modulated at a first frequency of oscillatory forcing described by a Strouhal ratio greater than about one; and (c) causing said fluid to flow through at least one location on the airfoil beyond about one quarter of the chord from the leading edge.
