A NEW FORM OF EXPRESSION FOR POWER ON BLADING IN A STAGE OF A TURBOMACHINE BASED ON THE METHOD OF EQUIVALENT REPLACEMENTS.

Abstract

A previous paperl presented the investigation of power transfer in a stage of a turbo machine by the method of equivalent replacements and a general scheme of development of mathematical profiles, W8S given. The manner of development of turbine and compressor profiles and their attendant characteristics were also given in the same paper. In this paper, the method of equivalent replacements is extended to formulate analytical expression for power on blading in a stage of a  turbomachine. The expression can be given in such a form that further analysis of stage characteristics can be done easily. A similar form has, till how, been applied sometimes in the theory of axial compressor, with certain limitations. The manner of computing the characteristics and their application to the analysis of stage characteristics of a turbomachine, are presented in this paper,
