The paper presents design approach to providing thermal protection of three-shaft turbofan engine turbine support oil cavities. The advantages and disadvantages of three-shaft engines are described. Basing upon the performed analysis, there are offered the potential decisions for providing thermal protection of turbine support oil cavities.
