Adjustment of elasticity characteristics of a composite elastic hub of helicopter main rotor for a range of operational temperature conditions

A procedure of ANSYS software application for solving an inverse problem of composite elastic element strength of the helicopter main rotor is presented. The simplex method is used to select parameters in minimization of the objective residual functional. Both one-dimensional and three-dimensional variants of searching are considered. The elasticity characteristics of elastic hub materials as a function of temperature, obtained as a result of adjustment, are presented.
