AnnotationThe results of the calculation of the stress-strain and limit states of the rotor blade of the ANSAT helicopter under different flight conditions, taking into account the possible damage of the blade in the butt section, are presented. The safety factors of the blade in the butt section depending on the azimuth angle of rotation of the blade are determined for the case when all the generalized forces change in proportion to one loading parameter.
Keywordslimit equilibrium theory, safety factor, method of variation of elastic constants, composite rotor blade of the helicopter, damage.
