普惠PT6涡桨、涡轴发动机结构及参数

PT6系列发动机是加拿大普惠公司的产品，包括涡桨和涡轴变种，是当前使用最为广泛的输出轴功率的航空发动机之一。在美国军用编号中，PT6的相应型号分别被命名为T74和T101。与首台在1963年面世的450SHP轴马力的PT6A发动机相比，如今PT6发动机系列的功率增加了四倍，功重比提高了40%，燃油消耗率降低了20%。据了解，PT6发动机已生产了52000多台，并被应用在130个不同领域，PT6发动机所在机队的飞行时间已累计多达亿小时。在全球航空领域普遍进行的重要任务中都能找到PT6发动机，从救援工作到预定的客运服务，从货运服务到要客接送，从农业应用到军事飞行培训、从消防救火到搜救任务。PT6A发动机高可靠性也加速了20世纪80到90年代的单发涡桨飞机的发展。EKHAUSTOUTLS'HEDUCTFONGEAnBOXFFtEE(POWEfliTUFieiNEFigure3-f导，frop«llfiisdrivflfi6/0freaturbineivTatain<igp<nd»nttyoEfti西EKHAUSTOUTLS'HEDUCTFONGEAnBOXFFtEE(POWEfliTUFieiNEFigure3-f导，frop«llfiisdrivflfi6/0freaturbineivTatain<igp<nd»nttyoEfti西£ornpr融±40「titrbiti。，PROPELLERDFEIVESH4FTCOMPRESSORCOMPRESSORTURBINEPT6A是涡桨发动机，PT6B和PT6C是涡轴发动机。PT6发动机的各变种及参数如下:VariantsPT6A家族包括了一系列自由涡轮涡桨发动机，输出功率500-1940shp(433-1447kWThermodynamicPowerMechanicalPropellerPower Height**Width**Length**ThermodynamicPowerClass*Class*PT6A'Small'600to500to1,900to21toto10759002,2002564PT6A'Medium'1,000to1,400850to1,0501,700to2,00066to2272PT6A'Large'1,400to1,900700to1,7001,700to2,0002269toThePT6Afamilysaseriesoffreeturbineturbopropengineproviding500to1,940shp(433tO1,447kW)SmallvariantequivalentshafthorsepowershafthorsepowerapplicationsPT6A-6525eshp500shpPT6A-11AG528eshp500shpAirTr二g十crAT-4。。Cckwai-7QrAcr—Pa-t (i—1A4RTlIKhInAPT6A-15AG715eshp680shpFrakesTurbocatPT6A-20579eshp550shpPT6A-21580eshp550shpBeechcraftKingAirC90A/B/SEBeechcraftBonanza(turbineconversion)PT6A-25,-25A580eshp550shpPT6A-25C783eshp750shpEmbraerEMB312TucanoPilatusPC-7/PC-7MKIITurboTrainerPZL-130Orlik/TC-IITurbo-OrlikPT6A-27715eshp680shpRppGhr*r十Mcrlp19QARQQdeHavillandCanadaDHC—6TwinOtter300HarbinY-12PmRroorPMR1iARondoivqxidLOIp+I-/if)ThrhoIfti-PilatusPC-6/BTurbo-PorterPT6A-28715eshp680shp
