The paper gives the results of investigation of the inlet flow irregularity influence on the film cooling formation. It is shown that the total pressure diagram irregularity in the set of nozzles inlet changes the structure of the film cooling in the initial region of the nozzle vane pressure side. Cooler flow displacement is registered in the regions of the total pressure gradient, interference of the perforation rows is broken, and overheat regions appear.
