The original author numerical and analytical methods, as well as finite element method and finite difference method were used. Results of the analysis are: - thermal and thermoelastic properties of the cooled blades from single crystal materials with taking into account on the orientation of the crystallographic axes; - singularities of vibratory stresses and their localization in the blades from single crystal material with damages; - stresses in the blades of the compressor at the vibrations in the gas-dynamic flow; - dynamic stress at impact and impulse loads; - aeroelasticity and crack resistance of elements of space technology. Practical recommendations to improve the strength of structural elements of promising energy constructions and aerospace engineering were developed. Results found the implementing at the enterprises of turbine engineering and aerospace engineering.
