Ever since the very beginning of aerodynamic flight, the accurate prediction of aerodynamic drag has been a major challenge in the aircraft design process. During the past 20 years, Computational Fluid Dynamics (CFD) has come to play an increasingly important role in this respect, but significant advances in CFD modeling capabilities are still needed. Future improvements in the performance of transport aircraft (notably fuel efficiency and hence direct operating costs) will largely depend on reducing aerodynamic drag. This will be achieved by design optimization and techniques such as laminar flow control, areas in which CFD will play a vital role.
The objective of this Lecture Series is therefore to present the state-of-the-art and current research directions in CFD-based drag prediction. The course is aimed at applied aerodynamicists and CFD researchers as well as aircraft designers.
An introductory lecture will discuss the importance of drag prediction for aircraft design and give an overview of the major factors involved in CFD-based drag prediction, which will be covered in detail in subsequent lectures. Novel methods for drag evaluation and decomposition from CFD solutions will be presented, as well as the latest advances of the wake integration method for drag prediction from wind tunnel tests.
The state-of-the-art of drag prediction capabilities of flow solvers using both multi-block structured grid and unstructured grid technology will be discussed.
Applications will focus mainly on the subsonic and transonic flight regimes of transport aircraft, including particular topics such as the design of high-lift systems and engine/airframe integration.
This course was previously delivered at the von Karman Institute in February 2003. The current offering represents an updating and repeat of the course at the National Institute of Aerospace in Hampton Virginia, USA. The directors of this course are Prof. H. Deconinck of the von Karman Institute, and Dr. Dimitri Mavriplis, of the National Institute of Aerospace (NIA).
