The examination shows that the aerodynamic
forces, i.e. lift and drag are hardly impacted by
active airflow. Figures 5-6 show that vacuum can
increase both lift and drag. The same graphs indicate
that the lift and drag forces decrease with
increasing overpressure. This fact can be proven
by the values of the coefficients of these two
forces given in Figures 7 and 8. Importantly, the
most beneficial case would be to increase the lift
force while reducing the aerodynamic drag force,
if these solutions were applied in aviation. These
results motivate to a more thorough examination of
this phenomenon on the airfoil upper surface. Any
further analysis should be carried out for a larger
model and a wider range of airflow velocities.
