Viscous drag reduction on transport aircraft [link]Paper  doi  abstract   bibtex   
In order to remain successful airframe manufacturers need to improve aircraft efficiency, performance, safety and comfort by consequently employing adequate technologies. In the very near future environmental aspects will be of growing importance challenging not only engine manufacturers but also the development of airframes. In all respects the classical field of aerodynamics offers still a large potential for aircraft improvement. Viscous drag accounts for about 50 % of the total drag of an aircraft. The present paper describes two possibilities of reducing drag; in a turbulent boundary layer by riblet film and secondly by keeping the boundary layer laminar over a major part of the wing. In both fields extensive research programs have been carried out culminating in successful flight tests with transport aircraft.
