From Wikipedia, the free encyclopedia
Helicopter dynamics is a field within aerospace engineering concerned with theoretical and practical aspects of helicopter flight. Its comprises helicopter aerodynamics, stability, control, structural dynamics, vibration, and aeroelastic and aeromechanical stability.[1]

By studying the forces in helicopter flight, improved helicopter designs can be made, though due to the scale and speed of the dynamics, physical testing is non-trivial and expensive. In 2013, a combination of stereophotogrammetry and rigid-body correction in post processing was shown to be a valid tool for performing these studies, and the dynamics of a Robinson R44 helicopter were measured during hovering flight, to determine blade dynamics (e.g. harmonics) and the deflection profile.[2]
