GAS-TURBINE ENGINE AND ITS CENTRAL STAGE AND REHEAT UNIT

摘要

FIELD: mechanical engineering; gas-turbine engine. ^ SUBSTANCE: proposed gas-turbine engine has central stage arranged in gas duct of engine and part arranged higher in direction of main gas flow and part arranged lower, converging in radial direction, and flame stabilizer. Flame stabilizer is located in gas duct out of the limits of central stage. Central stage contains device to change direction of preliminary flow arranged in zone of edge of said converging in radial direction part arranged lower in direction of main gas flow and provided with surface diverging in direction of main gas flow. ^ EFFECT: provision of effective and reliable firing of reheat unit. ^ 9 cl, 4 dwg
