The role of time-history effects in the formulation of the aerodynamics of aircraft dynamics [PDF]

The scope of any aerodynamic formulation proposing to embrace a range of possible maneuvers is shown to be determined principally by the extent to which the aerodynamic indicial response is allowed to depend on the past motion.

The Dynamic Characteristic and Hysteresis Effect of an Air Spring

International Journal of Applied Mechanics and Engineering, 2015
In many applications of vibration technology, especially in chassis, air springs present a common alternative to steel spring concepts. A design-independent and therefore universal approach is presented to describe the dynamic characteristic of such ...
