Abstract

The effects of climate change and rising fuel costs have caused airlines to search for new ways to decrease the drag and consequently fuel consumption of modern transport aircraft. One method that has been proposed is replacing the Fowler flap with a simplified plain flap and active flow control. This would allow for the removal of external support hardware and could result in fuel savings of up to 2.25%. Numerical simulations have been performed on the NASA Common Research Model in a Simplified High Lift configuration with Active Flow Control (CRM-SHL-AFC). The results of both steady state jets and transient fluidic oscillators applied to the SHL configuration are compared to the NASA Common Research Model with a conventional High Lift geometry (CRM-HL). It is shown that the use of AFC results in increased lift force and improved circulation on the entire wing. However, the steady state jets were found to be incapable of increasing the lift to the level of the conventional CRM-HL.
