Principles of helicopter flight under various conditions are reviewed, giving special attention to the operation of the main rotor. A brief history of helicopter development is presented, together with a summary of the main components of a helicopter and a classification of the various types of helicopters. The characteristics of the main rotor and its operation during autorotation and during axial and oblique flow are considered.

These are a set of class notes for a gas dynamics/viscous flow course taught to juniors in Aerospace Engineering. It is expected that the student has some familiarity with concepts such as material derivatives, control volume analysis, etc.

Hypersonics is the study of flight at speeds where aerodynamic heating dominates the physics of the problem. Typically this is Mach 5 and higher. Hypersonics is an engineering science with close links to supersonics and engine design.

A theory of subsonic flight based on a combination of analysis and computation. We uncover a mechanism for the generation of substantial lift at the expense of small drag of a wing, which is fundamentally different from the classical theories.

A documentary journey into the history of aerodynamics in America. How ideas about aerodynamics first developed and how the technology evolved to forge the airplane into the revolutionary machine is the epic story told in this book.
