Abstract

The experience of using a set of programs that implement the finite element method to determine overloads during the splashdown process of a helicopter with and without installed emergency splashdown system, is considered. The calculation results are compared with experimental data in order to determine the applicability of the finite element method in solving problems of hydrodynamic loading of a helicopter.
