Abstract
In static aeroelasticity we have considered various mathematical models of aeroelastic systems. In all of these, however, the fundamental physical content consisted of two distinct phenomena, ‘divergence’ or static instability, and loss of aerodynamic effectiveness as typified by ‘control surface reversal’. Turning to dynamic aeroelasticity we shall again be concerned with only a few distinct fundamental physical phenomena. However, they will appear in various theoretical models of increasing sophistication. The principal phenomena of interest are (1) ‘flutter’ or dynamic instability and (2) response to various dynamic loadings as modified by aeroelastic effects. In the latter category primary attention will be devoted to (external) aerodynamic loadings such as atmospheric turbulence or ‘gusts’. These loadings are essentially random in nature and must be treated accordingly. Other loadings of interest may be impulsive or discrete in nature such as the sudden loading due to maneuvering of a flight vehicle as a result of control surface rotation.
