AB  - Shock control bumps (SCB) are a transonic flow control device that aim to reduce theoverall drag due to a normal shock on a typical passenger jet at cruise. The concept of adaptiveSCB which can be deployed for best use are investigated through an aero-structuraldesign tool that produces optimal geometries. The optimizer uses a surface based performancemetric to highlight the importance of the flow quality around the SCB as wellas including a structural element that is required to provide the necessary flexibility todeform. The performance metric produces the target pressure distribution and successfullysmears the shock. It is found that the structural constraint does not inhibit bumpheight and global airfoil performance is not significantly a↵ected, L/D varies < 0.6%. Theaerodynamic pressure loading can be utilised to produce a new family of SCB geometriesthat are unachievable with mechanical actuation alone. The study shows that adaptiveSCB that exploit the naturally occurring pressure field around an airfoil in a passive wayare a feasible technology to mitigate the poor o↵-design performance of static SCB.
