Abstract (English):
The analysis of results of technological impact research upon operation characteristics of science intensive products and the ways to increase parts life of a hot area in aircraft and rocket jet engines is shown. It is shown that the basic factor of promising products for life increase consists in thermal-insulation increase and cooling jet nozzles and combustion chambers. For this the investigations are carried out for new heat-resistant material and protective coating development.
