FIELD: mechanical engineering+ADs- gas-turbine engines. SUBSTANCE: proposed reheat unit of gas-turbine engine contains prechamber with ring flame stabilizers arranged at outlet of diffuser formed by its housing and fairing of turbine rear support. Oscillations suppressor made in form of number of acoustic waveguides communicating peripheral zones of unit gas space is installed before prechamber. Length of acoustic waveguides is determined by patent protected equation. EFFECT: simplified design, reduced mass of reheat unit owing to suppression of tangential oscillations of Ist and 2 nd modes. 2 cl, 3 dwg |
