Beschreibung
The book addresses computational methods for solving the problem of vibration, response, loads and stability of a helicopter rotor blade modeled as a rotating beam with flap or out-of-plane bending. The focus is on explaining the implementation of the finite element method in the space and time domain for the free vibration, aeroelastic response and stability problems. The use of Floquet analysis for the aeroelastic stability analysis of rotor blades is also shown. The contents of the book will be useful to researchers in aerodynamics and applied mechanics, and will also serve well professionals working in the aerospace industry.
Fills a gap in the literature between textbooks on helicopter dynamics and papers published in journals
Illustrates finite element in space and finite element in time, a powerful method for systems governed by periodic differential equations
Uses many examples to illustrate the numerical methods, provides correlation of results with published literature
Provides Matlab code for material used in the book
