An overview of the physics, concepts, theories, and models underlying
the discipline of aerodynamics.
This book offers a general overview of the physics, concepts, theories,
and models underlying the discipline of aerodynamics. A particular focus
is the technique of velocity field representation and modeling via
source and vorticity fields and via their sheet, filament, or
point-singularity idealizations. These models provide an intuitive feel
for aerodynamic flow-field behavior and are the basis of aerodynamic
force analysis, drag decomposition, flow interference estimation, and
other important applications. The models are applied to both low speed
and high speed flows. Viscous flows are also covered, with a focus on
understanding boundary layer behavior and its influence on aerodynamic
flows.
The book covers some topics in depth while offering introductions and
summaries of others. Computational methods are indispensable for the
practicing aerodynamicist, and the book covers several computational
methods in detail, with a focus on vortex lattice and panel methods. The
goal is to improve understanding of the physical models that underlie
such methods. The book also covers the aerodynamic models that describe
the forces and moments on maneuvering aircraft, and provides a good
introduction to the concepts and methods used in flight dynamics. It
also offers an introduction to unsteady flows and to the subject of wind
tunnel measurements.
The book is based on the MIT graduate-level course "Flight Vehicle
Aerodynamics" and has been developed for use not only in conventional
classrooms but also in a massive open online course (or MOOC) offered on
the pioneering MOOC platform edX. It will also serve as a valuable
reference for professionals in the field. The text assumes that the
reader is well versed in basic physics and vector calculus, has had some
exposure to basic fluid dynamics and aerodynamics, and is somewhat
familiar with aerodynamics and aeronautics terminology.
