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.Wayne Johnson ... A wing extension, outboard of the nacelle, can be used to increase the wing aspect ratio. ... The wing also is responsible for a large hover download (10% is typical), and avoiding the coupled rotor and wing aeroelastic instability called whirl flutter requires a thick wing ... To reduce the profile power and increase propulsive efficiency, the rotor is slowed for airplane mode operation.
