About an original method of optimizing the design of axial compressor cascades operating in the stability domain
Journal Title: INCAS BULLETIN - Year 2013, Vol 5, Issue 4
Abstract
The purpose of this paper is to present the development of an original optimization method, designed in order to obtain improved performances due to the fact that all the operating regimes of the axial compressor AC cascades are found within the stability domain. The optimization method is based on new correlations between the cascade’s geometric and aerodynamic parameters and the universal map of cascades. A new criterion was introduced in purpose to assess the stability range of the running regimes in case of the AC cascades, by using the Zweifel number and the universal map of cascades. The optimization method elaborated by the author finds its practical validation in the wide-chord fan and compressor blades constructions that are already being built for modern turbofans, by constructors, as the General Electric, Pratt & Whitney and Rolls-Royce. The motivation of the constructors is to achieve the dynamic stability, but from the author’s point of view, the static stability was also included.
