Principles of helicopter flight under
various conditions are reviewed in this note, 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.
This book
describes the recent progress in some engine technologies and active flow
control and morphing technologies and in topics related to aeroacoustics and
aircraft controllers. Both the researchers and students should find the material
useful in their work.
