Theoretical Aerodynamics is designed to serve as a user friendly text for a full course on theoretical aerodynamics. The material is covered in such a way that the theory of aerofoil, its design features and performance aspects are introduced systematically, beginning with the basics required, and then gradually proceeding to higher level. The mathematics involved is presented in such a manner that it can be followed comfortably by even those who are not strong in mathematics. The examples are designed to fix the theory studied in an effective manner. Throughout the book, the physics behind the process is clearly explained. The book begins with the basics about aircraft geometry, and forces acting on that. A chapter giving the essence of fluid mechanics, which is vital for learning this subject, follows.  This chapter is unique in that a student new to fluid mechanics can catch up quickly with the one who has learned the elementary level and is ready to learn wing theory. The subsequent chapters cover the theory and application of Joukowski transformation, the vortex dynamics, and wing theory in a systematic manner.  The author describes the fundamental theory of wing for both the beginners to fluid dynamics and the engineers who want to understand it quickly. The mechanism of the aerodynamic force generation by two-dimensional and three-dimensional (finite span) wings is explained based on the elements of the fluid dynamics.        Contents includes: Essence of Fluid Mechanics, Kinematics of Fluid Flow, Source Sink Pair, Turbulence,  Conformal Transformation,  Joukowski Hypothesis, Vortex Theory, Stokes Theorem,  Helmholtzs Vortex Theorems, Thin Aerofoil Theory, Panel Method, and Finite Aerofoil Theory. Each chapter begins with an introduction and ends with a summary and exercises.
