FIELD: engines and pumps.
SUBSTANCE: system of plasma screening of boundary layer downstream includes film cooling holes and plasma generator. Film cooling holes are made through a wall, they are arranged at an angle directed downstream from cold wall surface to warm wall surface. Plasma generator is arranged downstream in relation to film cooling holes in order to generate plasma spreading downstream in relation to film cooling holes. Another invention refers to above mentioned system of plasma screening based on aerodynamic profile of gas turbine engine blades. One more invention of the group refers to method of operation of system of plasma screening of boundary layer, according to this method actuation of plasma generator for plasma generation spreading downstream in relation to film cooling holes, made through the wall, and along external hot wall surface is performed.
EFFECT: increasing efficiency of film cooling of gas turbine hot surfaces.
