description: The purpose of this paper is to research the usage expediency of aviation engine turbine spools counter-rotation technology. In order to do this, the special program code was written and the gas flow multiregime quasi-two-dimensional calculations were done in three different turbine schemes of two different aircraft engines classes. According to the obtained data, two objective functions were calculated â turbine inner efficiency Î·T and theoretical flight cycle fuel consumption ; and also, losses-reactivity and losses-twist depedency graphics, and gaspath distribution plot of working fluid velocity were drawn. The next step was to validate gained data with the computer CFD calculations in the Ansys CFX software. Afterall, based on the data obtained, the conclusion about the counter-rotating turbine usage expediency was made from the turbine inner efficiency and fuel consumption point of view of two aviation engine classes.
