Rotary-Wings

The basic concepts and mathematical tools for the development of the aeroelastic models of rotary wing systems are outlined. The chapter begins with a general introduction to the problems associated with the aeroelasticity of rotary wings, including a physical insight into the nature of the specific phenomena involved. Next, the development of simplified aeroelastic models for rotary wings in hovering and forward flight is presented and the characteristic mechanical and aerodynamic contributions are discussed. Finally, the solution methods that are of interest to rotorcraft designers are described.
