Summary

The influence of tangential slot injection in an attached, turbulent boundary layer on the pressure distribution of an airfoil is investigated for transonic freestream Mach numbers. The flow field is calculated by matching finite-difference solutions of the transonic small disturbance equation and the boundary layer equations. The results, obtained for different slot positions and injection rates, indicate that the surface pressure distribution can significantly be changed by tangential injection.
