Inverse problem for axisymmetrical paraboloidal gas turbine stage

Romuald Puzyrewski, Krystyna Namieśnik
The paper presents a solution to the inverse problem for a gas turbine stage within the frame of axisymmetrical stationary flow model. The shapes of axisymmetrical stream surface are assumed to be paraboloi-dal and flow is isentropic. The solution yields the curvatures of blade channels and the distribution of parameters in the entire flow field.
