This comprehensive book presents, in depth, what engineers need to know about modeling rotorcraft aeromechanics. The focus is on analysis, and calculated results are presented to illustrate analysis characteristics and rotor behavior. The book begins with an introduction to rotorcraft aerodynamics, blade motion, and performance and then covers advanced topics in rotary wing aerodynamics and dynamics.

Abstract: Aerodynamic simulation has reached a level of sufficient maturity, that not only benchmark problems are solved easily, but real application data can be delivered even for such complex configurations like rotorcraft. Leaving behind generic cases like driven cavity or isotropic turbulence and moving on to actual engineering, several fields more or less remotely related to aerodynamics have to be taken into account to provide accurate and reliable value. This is less a matter of ingenious invention, but much more so a careful selection of usable procedures for problems identified to matter, and mostly hard work, putting the pieces together and shaking all the wrinkles out.

Helicopter rotor aeroelastic and aeromechanical stability predictions for four data sets were made using industry and government stability analyses and compared with data at a workshop held at Ames Research Center, August 2-3, 1988. The present report contains the workshop comparisons. Keywords: Aeromechanic stability; Rotary wing aircraft; Aeroelastic stability; Rotorcraft dynamics; Aerodynamic stability; Aeroelasticity; Helicopter rotors. (edc).
