TURBOMACHINE COOLED BLADE Russian patent published in 1995 - IPC

Abstract RU 2028456 C1

FIELD: gas-turbine manufacture. SUBSTANCE: as jet flows over edge while lagging negative feedback provided by pressure waves propagating in cavities is acting, flow becomes unsteady and intensive oscillations are self-excited in jet-cavity system whose frequency approaches resonance-turned frequency of cavities. EFFECT: improved design. 3 dwg
