RESUMO

A numerical simulation technique at the stage of conceptual design of aircraft mechanical systems is considered. The results of a kinematic analysis and load design using the light helicopter mathematical model and calculations of rotor blade flutter are given. Examples of bench and flight test simulations are presented. Using the prediction of the routine flying trajectory of a light helicopter, the possibility of determining cyclically alternating loadings in rotor system elements is considered.
