The behavior of a VLFS an airplane during takeoff/landing run in wave condition

摘要

The main aim of this paper is a transient behavior of a VLFS subjected to dynamic load induced by airplane landing and takeoff. A time-domain analysis method is applied to the hydroelasticity problems for this purpose. The method based on FEM scheme is to treat the structure and on Wilson's θ method to pursue time-step procedure taking advantage of the memory effect function for hydrodynamic effects. MF-300 which was designed as the first Mega-Float prototype structure is adopted as an example for VLFS runway.
