The paper considers the results of mathematical modeling of strain state of a non-uniformly heated ceramic frame of rotary heat exchanger of multi-purpose gas turbine engine with the power of 300 kW . Received a conclusion that the implementation of frame heat exchanger made from ceramics will enable the design of the rotary heat exchanger with high degree of regeneration (95-97%), without increasing the amount of air leaks through the seals of the heat exchanger.
