Buffeting in aircraft
WebJul 1, 1993 · 1. If the control surface assumes a trailing-edge-low attitude, it is statically underbalanced and a tail-heavy condition exists. See Figure 1. 2. If the control surface remains in a level (horizontal) attitude, it is said to be statically 100% balanced and its center of gravity (cg) is co-located with the hinge axis. 3. Dynamic aeroelasticity studies the interactions among aerodynamic, elastic, and inertial forces. Examples of dynamic aeroelastic phenomena are: Flutter is a dynamic instability of an elastic structure in a fluid flow, caused by positive feedback between the body's deflection and the force exerted by the fluid flow. In a linear system, "flutter point" is the point at which the structure is …
