Abstract

The procedure and results of a numerical analysis of an aircraft's dynamic state at abnormal falling at a takeoff stage are submitted. The problem about impact of an aircraft's bearing structure by an obstruction reproducing properties of a ground under the given impact's conditions is considered. The problem about non-stationary interaction is solved with use of a of finite element method (FEM) on the basis of which models of a load-bearing structure and an obstruction are designed. Operation is carried out at a support of the Russian Fundamental Researches Fund (the design N 06-08-01005).
