The paper presents a methodology which helps to avoid a great amount of costly experimental research. This methodology includes thermo-gas dynamic design of an engine and its mounts, the profiling of compressor flow path and cascade design of guide vanes. Employing a method elaborated by Howell, we provide a theoretical solution to the task of assessing the influence of the VGV blades' angle of rotation on the characteristic of a compressor. The finite element model of a VGV blade helps to solve some problems of strength and tune-out of resonance in the domain of a compressor's operating frequencies as well as the problem of determining the position of the pressure center and the location of a blade's pivotal point. Cinematic and dynamic analysis of the control linkage of VGVs is carried out in a MSC.ADAMS package. The investigation is based on geometric 2D and 3D models, gas-dynamic and strength analysis taking into account geometrical nonlinearity and based on the finite element method. The study is also based on the dynamic analysis according to the Euler-Lagrange equation, which describes the behavior of mechanical systems comprised of markers and the Craig-Bampton method implying the theory of superposition of vibrational modes.
