摘要

Objective of development of a low cost, light weight and compact gas turbine engine (GTE) can be achieved producing its parts and components of structural ceramics. Economic effectiveness of a GTE is enhanced through turbine inlet initial temperature increase, cooling air How reduction and waste heat recovery.
A ceramic material of high resistance and relatively low density enabies to develop light-weight and small size tubular heat exchangers (I IE) viable for a long-term service- with gas temperature being above l.000 ° C HE compactness is achieved by heat exchange enhancement over its paths, utilization of hybrid structures and resorting to a modular design concept Compactness factor tor these HEs is 515...720 m 2 m 3 while its specific output is 1.8. .6.6 kW/kg.
