The results reported pertain mainly to the classical 
or "fundamental" subdivisions in the theory of heat and mass transfer. 
They correspond to the laminar mode of flow, which is considered to 
be a subject explored in detail owing to advances in computational 
mathematics. The laminar mode has turned out to be most important 
and interesting in creating a new generation of gas-turbine power 
plants distinguished by high efficiency (60%) 
and specific power per unit flow rate of air (1 MJ/kg). 
The thesis is confimed that applied scientific-engineering 
developments give a powerful impetus to the formulation of fundamental 
studies and often determine the trend of the search for physical regularities. 
Being confined by the framework of a plenary report, we could not 
touch on all the aspects of the studies devoted to gas-turbine plants 
conducted at the Institute of High Temperatures of the Russian Academy 
of Sciences. Some of the results obtained have been published [1-5], 
while others another are being prepared for publication.
