ROTARY-WING AERODYNAMICS

Recent literature related to rotary-wing aerodynamics has increased geometrically; yet the field has long been without the benefit of a solid practical basic text. To fill that void in technical data NASA (National Aeronautics and Space Administration) commissioned the highly respected practicing engineers and authors W. Z. Stepniewski and C. N. Keys to write one. The result: Rotary-Wing Aerodynamics a clear concise introduction highly recommended by U.S. Army experts that provides students of helicopter and aeronautical engineering with an understanding of the aerodynamic phenomena of the rotor. In addition it furnishes the tools for quantitative evaluation of both rotor performance and the helicopter as a whole. Now both volumes of the original have been reprinted together in this inexpensive Dover edition. In Volume I: Basic Theories of Rotor Aerodynamics the concept of rotary-wing aircraft in general is defined followed by comparison of the energy effectiveness of helicopters with that of other static-thrust generators in hover as well as with various air and ground vehicles in forward translation. Volume II: Performance Prediction of Helicopters offers practical application of the rotary-wing aerodynamic theories discussed in Volume I and contains complete and detailed performance calculations for conventional single-rotor winged and tandem-rotor helicopters. Graduate students with some background in general aerodynamics or those engaged in other fields of aeronautical or nonaeronautical engineering will find this an essential and thoroughly practical reference text on basic rotor dynamics. While the material deals primarily with the conventional helicopter and its typical regimes of flight Rotary-Wing Aerodynamics also provides a comprehensive insight into other fields of rotary-wing aircraft analysis as well.
