Description: The usefulness of helicopters lies in their unique ability to take off and land vertically, to hover, and to fly forward, backward, or sideways. These very qualities, however, come at a high cost involving complex aerodynamic problems. This modern treatment, written by an internationally recognized expert, explains the aerodynamic principles of helicopters and other rotating-wing vertical lift aircraft. Besides the history of helicopter flight, basic methods of analysis, and performance and design issues, the author covers airfoil flows, unsteady aerodynamics, dynamic stall, and rotor wakes. Each chapter concludes with homework problems.
