DROP ANALYSIS OF THE SKID LANDING GEAR OF THE LIGHT HELICOPTER

The analysis of helicopter during landing includes both complicated experimental tests and numerical calculation. Up to now very simple models in helicopter engineering have been used in Russia. Contemporary investigation of these problems involves using modern engineering software. The mechanical models included in these software allow to describe highly nonlinear dynamic behavior of engineering structure. This article contains rudimentary step-by-step development of numerical model to analyze behavior of skid landing gear in order to obtain optimal numerical model. Main points of the optimal numerical model are related to reducing cost of the verification experiment as well as hardware requirements. The base software for numerical activities is LS-DYNA with pre- and post- processors in ANSYS.
