The aim of research - the development of techniques of mathematical description and variation of surfaces for the purposes of aerodynamic improvement of blade channels within gas turbine engine compressors. The research methods - analytical geometry methods, methods for function spline interpolation and construction of surfaces. The results obtained. The technique for the mathematical description of compressor wheel blades taking into account possibility of ones variation is developed; several ways of parametric description and variation of ones form are realized within the bounds of this technique. The technique for the mathematical description and variation of surfaces, bounding the blade channels of compressor wheels. The analysis of possibility compressor wheel blade channels description and variation is carried out. The estimations of variable parameters number, which are required for blade channel form description with acceptable accuracy is performed. Field of application - aviation gasturbine engine compressors design. Product Description popup.authors Болотова Наталія Вікторівна Мелашич Сергій Васильович popup.nrat_date 2020-04-02 Close
