Aerodynamics of Tandem Wing Aircraft: From Dinosaurs to UAVs and Supersonic Planes

Description

This book contains extensive data about tandem wing aircraft. It includes a review of modern flying vehicles with four fixed wings, a review of analytical, numerical and experimental methods; results of the studies about aerodynamics; dependencies between geometrical parameters and aerodynamic characteristics, practical recommendations in development and optimizing of tandem wing aircraft to provide high lift-to-drag ratio, stability, and controllability. This is an ideal book for graduate students, researchers, and engineers working in fields of aerodynamics and conceptual design of the aircraft especially UAVs, ground-effect vehicles, and convertiplanes.   Preface Acknowledgments Contents About the Author Symbols and Abbreviations Chapter 1: Historical Review 1.1 Introduction 1.2 Review of Tandem Wing Aircraft 1.3 Conclusions References Chapter 2: Determination of Tandem Wing Aircraft Aerodynamic Characteristics 2.1 Physics of the Airflow Around a Tandem Wing Aircraft 2.2 Analytical Methods 2.2.1 Flow Deceleration 2.2.2 Flow Turbulization 2.2.3 Downwash and Upwash 2.2.4 Lift Coefficient 2.2.5 Drag Coefficient 2.2.6 Pitching Moment Coefficient 2.2.7 Rolling Moment Coefficient 2.2.8 Yawing Moment Coefficient 2.2.9 Control Surface Effectiveness 2.3 CFD Methods 2.4 Experimental Methods 2.5 Comparison of Analytical/CFD Method with Experimental Data 2.6 Conclusions References Chapter 3: Effect of Geometric Parameters on Aerodynamic Characteristics 3.1 High Wing and Low Wing 3.2 Wingspan Ratio 3.3 Airfoils and Angles of Setting 3.4 Stagger and Vertical Gap 3.5 Wings´ Dihedral Angles 3.6 Wingtip Devices on Forward and Rear Wings 3.7 Aerodynamic Features of Folding Design 3.8 Conclusions References Chapter 4: Recommendations Regarding Aerodynamic Design of Tandem Wing Aircraft References Conclusions Advantages of Tandem Wing Aircraft Drawbacks of Tandem Wings References Index
