Development of modern civil aviation has a tendency to obtain maximum engine power at as less fuel comsumption as possible. Mainly this is reached by increasing temperature of gases before high-pressure turbine. One of possibility to increase temperature in the engine is to find out new materials, which were able to resist the necessary temperatures. One of such new materials is ceramics. It is able to survive at very high temperatures, but has low resistance at compression and pulling stresses. This work introduces with new construction blade. Ceramics are used in the construction elements of turbine. To provide necessary strength of ceramics an unusual way of elements loading is used, allowing the elements to work under compressing stresses. Using of blades from ceramic allows decries specific fuel consumption up to 6-12% because decreasing of consumption of air for blades cooling.
