In this paper, based on the technical theory developed by the article contributors and the theory designed for twisting of a composite laminated rod of any cross section, a computer program for numerical stress-strain analysis of laminated composite blades in the centrifugal forces field is presented. The naturally twisted laminated composite blade is considered to be under the combined action of the tensile stresses, bending and twisting moments or under the influence of centrifugal forces. In the program, the technological problem of blade unfolding into petals is solved. These petals lie in planes which are parallel to the rod axis and appear due to the varying cross-section along the length of the blade. The investigated blade is represented with eight sections. The results of research on stress-strain behaviour of boron aluminium laminated compressor blades which operate in the fields of centrifugal forces are analysed.
