The design of the high lift system has a profound effect on the sizing and total performance of transport aircraft, both civil and military. This paper first reviews the fundamentals of high-lift systems design and the phenomena that govern their performance. A review of the computational methods available to the high lift designer, with examples of their validity, is then presented. New developments in flow diagnostic techniques are reviewed. Finally, examples of several Boeing high-lift design efforts are presented. Emphasis is placed on the use of computational aerodynamic methods and the synergistic effect of using those methods in parallel with testing. Finally a list of todays ten most important issues is presented.
