GAS-TURBINE ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering; engines. SUBSTANCE: proposed gas turbine engine contains intake cone, engine shaft and external load drive shaft from side of engine intake housing. Flexible coupling is installed in inner space of cone between shafts of engine and external load drive. ratio of outer diameter of flexible coupling to distance from coupling to center of shaft bearing is 1-5. Ratio of outer diameter of flexible coupling to diameter of cone inlet hole is 1.2-3. Slot space formed between walls of intake cone is connected by radial channels with inner space of cone. invention improves reliability of gas-turbine engine owing to reduction of loads on engine shaft and prevention of icing and erosion wear of transmission members. EFFECT: improved reliability of gas-turbine engine. 2 cl, 2 dwg
