Intended for use in graduate-level courses and by practicing engineers, the volume covers all of the important topics needed for the complete understanding of rotorcraft structural dynamics and aeroelasticity, including basic analysis tools, rotating beams, gyroscopic phenomena, drive system dynamics, fuselage vibrations, methods for controlling vibrations, dynamic test procedures, stability analysis, mechanical and aeromechanical instabilities of rotors and rotor-pylon assemblies, unsteady aerodynamics and flutter of rotors, and model testing. The second edition provides more up-to-date solution techniques, as well as new material that the author has developed since the first edition. New chapters have been included dealing with elastomeric devices, airfoil sections with an emphasis on composites, "cross-over" topics, and a historical perspective on the subject material. A new appendix has been provided presenting basic material on composites. The text is further enhanced by the inclusion of problems in each chapter. 410 0$aAIAA education series. 606 $aHelicopters$xAerodynamics 606 $aAeroelasticity 615 0$aHelicopters$xAerodynamics. 615 0$aAeroelasticity. 676 $a629.132/362 700 $aBielawa$b Richard L$0316054 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910953225003321 996 $aRotary wing structural dynamics and aeroelasticity$9810121 997 $aUNINA
