Abstract
An experimental investigation has been undertaken to investigate the potential of streamwise slots as a shock / boundary layer interaction control device. Results indicate that slots delay the onset and reduce the extent of shock induced separation. Due to the reduction in separation, flow breakdown is delayed until higher Mach numbers, resulting in increased lift and decreased drag. As well as the delay in fully separated flow, the shock wave position was found to be practically constant on the aerofoil fitted with control, suggesting that slots may also delay buffet onset.
