METHOD OF AND DEVICE FOR INJECTION COOLING AND PARTITION FOR SAID DEVICE Russian patent published in 2007 - IPC F02C7/12 

FIELD: mechanical engineering; gas-turbine engines.

SUBSTANCE: device for injection cooling of parts of gas-turbine engine, having elongated form and providing cooling beyond the limits of air pressure chamber, has inner wall, injecting sheet and set of supports providing holding of inner wall at distance from injecting sheet. Device is furnished with partition installed between inner wall and injecting sheet and provided with collecting zone into which force - cooling air gets. Channel made in partition communicates with collecting zone and projects beyond the limits of air pressure chamber. Channel is provided with holes to pass force-cooling air. Projecting sections made on partition limit channel. They are arranged near outlet holes for force-cooling air made in inner wall.

EFFECT: increased velocity of air used for injection cooling, improved film cooling.
