GAS-TURBINE ENGINE REHEAT UP (VERSIONS) Russian patent published in 2004 - IPC

Abstract RU 2229614 C1

FIELD: mechanical engineering+ADs- gas0turbine 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. Inlet and outlet of diffuser are additionally communicating with at least one acoustic waveguide arranged over periphery or inside fairing. Length of acoustic waveguide is determined by patent protected equation. EFFECT: simplified design, reduced mass of reheat unit by suppressing pressure oscillations in reheat unit and thus providing operation of reheat unit without regular oscillations over entire working range. 3m cl, 1 dwg
