摘要

Aero elasticity is a relatively new branch of applied mechanics that studies the interaction of fluids and flexible solid bodies. It is concerned with the interaction of aerodynamics, dynamics, and elasticity. Aerodynamic forces acting on the aircraft during flight cause deformations of the elastic structure, resulting in variations in aerodynamic forces. Aero elasticity is commonly used in the field of aircraft engineering. Aero elasticity can be broadly divided into two fields: static aero elasticity, which deals with an elastic body’s static or steady-state response to a fluid flow, and dynamic aero elasticity, which engages with the body’s dynamic (commonly vibrational) response. Static aero elastic phenomena that do not include inertial forces are distinguished by unidirectional structure deformation, whereas dynamic aero elastic phenomena that do include inertial forces are distinguished by the oscillatory property of structure deformation. Since aircraft must be lightweight and withstand high aerodynamic loads, they are susceptible to aero elastic effects. The following aeroelastic problems are avoided by aircraft:1. Divergence occurs when aerodynamic forces increase the angle of attack of a wing, increasing the force.2. Control reversal occurs when control activation produces a contrary aerodynamic moment, which minimizes or, in extreme cases, reverses control effectiveness; and 3. Flutter, which is an unacceptable vibration that can lead to an aircraft’s destruction.
