METHOD OF FILM COOLING AND APPLIANCE FOR ITS IMPLEMENTATION

A cooling by a film method includes blowing of the cooling air onto a hot blade surface. By delivering a hot air to the blade surface across the main gas flow at least one row of the pulsed vortexes is formed. A device for the cooling by a film method implementation contains a gas turbine blade with...

Zusammenfassung:A cooling by a film method includes blowing of the cooling air onto a hot blade surface. By delivering a hot air to the blade surface across the main gas flow at least one row of the pulsed vortexes is formed. A device for the cooling by a film method implementation contains a gas turbine blade with the grooves, in which on the rarefaction and pressure surface along the blade height the pits are disposed, and in every of which at the upper by the flow direction half the holes are made for introducing the cooling air.
