Abstract : After citing several sources given different methods for calculating the temperature condition of a gas turbine rotor blade, the author concludes that, on the whole, the problem of temperature distribution along the rotor blade height, considering the variation of all factors entering into the system of differential equations describing the phenomenon of heat-exchange, remained unsolved. In the present paper, according to the author, the given problem is approximately solved using asymptotic methods for the most general case, whereby the error of actual relationships of the quantities entering into the system of equations does not exceed 1--3%.
