GAS-TURBINE ENGINE REHEAT UNIT Russian patent published in 2004 - IPC

Abstract RU 2229616 C1

FIELD: mechanical engineering; gas-turbine engines. SUBSTANCE: proposed reheat unit of gas-turbine engine contains prechamber with ring flame stabilizers installed in housing and arranged at outlet of diffuser formed by its housing and fairing of turbine rear support. Oscillations suppressor installed before prechamber is made in form of row of acoustic waveguides communicating peripheral zones of unit gas space with central zone at fairing. Length of acoustic waveguides is found from equation where λ is wave-length of radial mode of oscillations. EFFECT: simplified design, reduced mass of reheat unit. 2 cl, 2 dwg
