    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.


    • 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.

    Dr. Jochen Wild is a Research Scientist at the Institute of Aerodynamics and Flow Technology of the German Aerospace Center DLR. After studying aerospace engineering at Technical University Munich and Mechanical Engineering at Technical University Darmstadt, he joined DLR as a PhD candidate. In 2001, he received his doctorate from the Technical University Braunschweig. From 2008 to 2018, he led the High-Lift Aerodynamics team within the Transport Aircraft Department, which he headed in 2018/2019.

    He has 25 years of experience in high-lift aerodynamics, high-lift system design and active flow control, with CFD and by wind tunnel testing. He has more than 100 contributions to scientific conferences, and about 50 contributions to books and scientific journals. For his scientific work, he was awarded with the Deutsche Lufthansa Stiftungspreis (1996), the Hermann-Blenk-Award (2013) and the EREA Best Paper Award (2015 and 2019). Since 2014, he has lectured on High-Lift Aerodynamics at the Technical University Braunschweig.

    He has participated in numerous national and international projects, including the coordination of high-lift aerodynamics projects. He contributed to the EUROLIFT I+II projects, the CleanSky Smart Fixed Wing Aircraft project and the European FP7 project AFLoNext and currently to the CleanSky 2 LPA HLFC-Wing project. He coordinated the European FP7 project DeSiReH and the Active Flow Control activities within the AFLoNext project. Currently, he coordinates the Horizon 2020 project UHURA dealing with unsteady aerodynamics of high-lift systems.
