AbstractA hot topic in today's debate on global warming is drag reduction in aeronautics. The most bene cial concept for drag reduction is to maintain the major portion of the airfoil laminar. Estimations show that the potential drag reduction can be as much as 15%, which would give a signi cant reduction of NOx and CO emissions in the atmosphere considering that the number of aircraft take o s, only in the EU, is over 19 million per year. An important element for successful fow control, which can lead to a reduced aerodynamic drag, is enhanced physical understanding of the transition to turbulence process.
