This book presents a detailed look at high-lift aerodynamics, which deals with the aerodynamic behavior of lift augmentation means from various approaches. After an introductory chapter, the book discusses the physical limits of lift generation, giving the lift generation potential. It then explains what is needed for an aircraft to fly safely by analyzing the high-lift-related requirements for certifying an aircraft. Aircraft needs are also analyzed to improve performance during takeoff, approach, and landing. The book discusses in detail the applied means to increase the lift coefficient by either passive and active high-lift systems. It includes slotless and slotted high-lift flaps, active and passive vortex generating devices, boundary and circulation control, and powered lift. Describing methods that are used to evaluate and design high-lift systems in an aerodynamic sense, the book briefly covers numerical as well as experimental simulation methods. It also includes a chapter on the aerodynamic design of high-lift systems. FEATURES Provides an understanding of the physics of flight during takeoff and landing from aerodynamics to flight performance and from simulation to design Discusses the physical limits of lift generation, giving the lift generation potential Concentrates on the specifics of high-lift aerodynamics to provide a first insight Analyzes aircraft needs to improve performance during takeoff, approach, and landing Focuses on civil transport aircraft applications but also includes the associated physics that apply to all aircraft This book is intended for graduate students in aerospace programs studying advanced aerodynamics and aircraft design. It also serves as a professional reference for practicing aerospace and mechanical engineers who are working on aircraft design issues related to takeoff and landing.

In aircraft design the constraints between the high speed cruise and the low speed takeoff and landing conditions force the designer to incorporate some form of high lift to device to improve the lift at low speed. Most aircraft, be they civil or military, have some form of high lift device that is normally used exclusively during take-off and landing, and for many years this has mainly been a mechanical alteration of the wing section shape over the inboard part of the wing. The complications of sweep, be it forward or backward, engine installation, lateral controls, undercarriage installation and high speed wing design have always been accommodated within the configuration of a trailing edge flap and in some cases a leading edge slat. This paper concentrates principally on the mechanical high lift device as it is used on transport type aircraft and examines the design process and recent progress on both the development of high lift device design and on the understanding of the physics of the flows that has been reached. It also suggests the likely future development and the way in which this may be achieved.

Since the education of aeronautical engineers at Delft University of Technology started in 1940 under tae inspiring leadership of Professor H.J. van der Maas, much emphasis has been placed on the design of aircraft as part of the student's curriculum. Not only is aircraft design an optional subject for thesis work, but every aeronautical student has to carry out a preliminary airplane design in the course of his study. The main purpose of this preliminary design work is to enable the student to synthesize the knowledge ob tained separately in courses on aerodynamics, aircraft performances, stability and con trol, aircraft structures, etc. The student's exercises in preliminary design have been directed through the years by a number of staff members of the Department of Aerospace Engineering in Delft. The author of this book, Mr. E. Torenbeek, has made a large contribution to this part of the study programme for many years. Not only has he acquired vast experience in teaching airplane design at university level, but he has also been deeply involved in design-oriented re search, e.g. developing rational design methods and systematizing design information. I am very pleased that this wealth of experience, methods and data is now presented in this book.

The U.S. air transportation system is very important for our economic well-being and national security. The nation is also the global leader in civil and military aeronautics, a position that needs to be maintained to help assure a strong future for the domestic and international air transportation system. Strong action is needed, however, to ensure that leadership role continues. To that end, the Congress and NASA requested the NRC to undertake a decadal survey of civil aeronautics research and technology (R&T) priorities that would help NASA fulfill its responsibility to preserve U.S. leadership in aeronautics technology. This report presents a set of strategic objectives for the next decade of R&T. It provides a set of high-priority R&T challengesâ€"-characterized by five common themesâ€"-for both NASA and non-NASA researchers, and an analysis of key barriers that must be overcome to reach the strategic objectives. The report also notes the importance of synergies between civil aeronautics R&T objectives and those of national security.
