On the Transient Response of a Two-Dimensional Floating Runway During Airplane Take-Off

The transient response of a two-dimensional floating runway subject to dynamic moving load due to airplane landing and take-off is studied in this paper. This hydroelastic problem is formulated by directly coupling the structure with fluid, by use of the Level I Green-Naghdi theory for the fluid motion and the Kirchhoff thin plate theory for the runway. The coupled fluid-structure system, together with the appropriate jump conditions are solved by the finite difference method. The results, including hydroelastic deformation of the runway and the drag force on the airplane are predicted and compared with the available results. Favorable agreements are observed. Parametric studies are carried out to identify the important factors for the design of floating runways.
