The growing number of scientific and technological applications of
plasma physics in the field of Aerospace Engineering requires that
graduate students and professionals understand their principles.
This introductory book is the expanded version of class notes of
lectures I taught for several years to students of Aerospace
Engineering and Physics. It is intended as a reading guide,
addressed to students and non-specialists to tackle later with more
advanced texts. To make the subject more accessible the book does
not follow the usual organization of standard textbooks in this
field and is divided in two parts. The first introduces the basic
kinetic theory (molecular collisions, mean free path, etc.) of
neutral gases in equilibrium in connection to the undergraduate
physics courses. The basic properties of ionized gases and plasmas
(Debye length, plasma frequencies, etc.) are addressed in relation
to their equilibrium states and the collisional processes at the
microscopic level. The physical description of short and long-range
(Coulomb) collisions and the more relevant collisions (elementary
processes) between electrons' ions and neutral atoms or molecules
are discussed. The second part introduces the physical description
of plasmas as a statistical system of interacting particles
introducing advanced concepts of kinetic theory, (non-equilibrium
distribution functions, Boltzmann collision operator, etc). The
fluid transport equations for plasmas of electron ions and neutral
atoms and the hydrodynamic models of interest in space science and
plasma technology are derived. The plasma production in the
laboratory in the context of the physics of electric breakdown is
also discussed. Finally, among the myriad of aerospace applications
of plasma physics, the low pressure microwave electron multipactor
breakdown and plasma thrusters for space propulsion are presented
in two separate chapters.
