This report presents the contribution of the characteristic values to the lift acting on a circular cylinder with a tangential blowing jet immersed in a uniform shear flow. The characteristic values include the angle and the pressure coefficient of the stagnation point, separation points, minimum pressure and back pressure. A series of experiments was made for seven shear parameters K=0, ±0.03, ±0.045, ±0.15 and Reynolds number 6×10⁴. All variable characteristics with increasing lift coefficient were clearly distinguished into three categories of which one was influenced only by the shear parameter, another was influenced only by the location of the tangential blowing jet, and the third was influenced by both parameters.
