  • Cracking and reduction in the strength of products of structural ceramics and cermet is an  unresolved   challenge   for  laser additive processes. Its solution was   realized using  non-shrink ceramics for all CGTE devices.

As a  result,

-          abandonment of cooling at temperatures of 1600±50°К, increasing the engine efficiency to 44-46%;

-          elimination of NOx and СО  emissions (the flame with temperature below 1773 К);

-           3-4 times reduction in the engine mass;

-          operation hours expansion without refueling;

-          increasing the operation  reliability for the multi-module engine execution by switching off and connecting  of separate modules that always operate  at the most reliable nominal duty. 

A 2kW uncooled micro engine, which testing verified  the design parameters (TIT = 1623 K, efficiency = 29%, NOx = 0%, CO = 0%),  was manufactured as a working model of the designed ceramic engine of 500 kW output (TIT = 1623 K,  efficiency = 46%, NOx£10 mg/Nm3, CO£10 mg/Nm3).
