GEAR DRIVE SYSTEM OF GAS TURBINE ENGINE FAN AND GAS TURBINE ENGINE CONTAINING SUCH SYSTEM

摘要

FIELD: engines and pumps.;SUBSTANCE: gas turbine engine fan gear drive system, providing reduced speed between turbine fan drive and fan, comprises suspension enabling flexible support to gear system parts, and lubrication system made with possibility to feed lubricant to gear system and removal of heat energy generated in gear system. Lubrication system has functional possibility of heat energy removal in amount of up to 2 % of power at gear system inlet. Gear system is made with possibility to transmit input power from fan drive turbine to fan with efficiency exceeding 98 %. Another invention of group relates to gas turbine engine with blower, compressor section, combustion chamber, fan drive turbine and the said fan drive gear system.;EFFECT: decreased overall dimensions, weight and lubrication system volume, due to limitation of its efficiency.;18 cl, 3 dwg
