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3.9亿小时。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。■•iI.rtfEXHAUSTOGTLEAIRIMLFtEQUCTrCHMGEARBOXFREE{POWER)TURBINECOMPRESSORTURBINEC如叩阳隔Powerlvr-bine&PropalltrshaftI7'■PO^ER"士规MMTOFt艾灯诒□L□uiput加tAccessorygearboConiprEss口『turbine口ry护>dalcgrpipre^PT6A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Figure了-枣民Propelfafsdrivefig«freelurtiinfirotateindepon-dvnttYalth甘仙mpre需arlurbEn*.■r^j□2ndstag;Etsl^cdiribLiitronir口ontitfiugHLUirtim-xrnprwwr二r^ductf^ngEfhrfaqk■円—7>HVariantsPT6Ahttp://www.pwc.ca/en/engines/pt6aPT6A家族包括了一系列自由涡轮涡桨发动机，输出功率500-1940shp(433-1447kW)ThermodynamicPowerClass*(ESHP***)MechanicalPowerClass*(SHP)PropellerLength**(Inches)Speed(Max.RPM)Height**(Inches)Width**(Inches)PT6A'Small'600to500to1,900to21to21.561.5to(A-11toA-140)10759002,2002564PT6A'Medium'1,000to850to1,700to2219.566to(A-41toA-62)1,4001,0502,00072PT6A'Large'1,400to700to1,700to2219.569to(A-64toA-68)1,9001,7002,00075.5ThePT6Afamilyisaseriesoffreeturbineturbopropengineproviding500to1,94Qhp(433to1,447kW)SmallvariantequivalentshafthorsepowershafthorsepowerapplicationsPT6A-6525eshp500shpPT6A-11AG528eshp500shpAirTractorAT-400SchweizerAg-CatG-164BTurbinePT6A-15AG715eshp680shpAirTractorAT-400AirTractorAT-501FrakesTurbocatSchweizerAg-CatG-164BTurbinePT6A-20579eshp550shpPT6A-21580eshp550shpBeechcraftKingAirC90A/B/SEBeechcraftBonanza(turbineconversion)PT6A-25,-25A580eshp550shpPT6A-25C783eshp750shpEmbraerEMB312TucanoPilatusPC-7/PC-7MKIITurboTrainerPZL-130Orlik/TC-IITurbo-OrlikPT6A-27715eshp680shpBeechcraftModel99A,B99deHavillandCanadaDHC-6TwinOtter300HarbinY-12EmbraerEMB110BandeiranteLetL-410TurboletPilatusPC-6/BTurbo-PorterPT6A-28715eshp680shpPT6A-29778eshp750shpPT6A-34783eshp750shpEmbraerEMB110Bandeirante/111EmbraerEMB821CarajaGrummanMallard(turbineconversion)JetPROPDIXPACP-750XSTOIQuestKodiakVazarDash3TurbineOtterVikingDHC-6TwinOtter400PT6A-34AG783eshp750shpAirTractorAT-502BFrakes/GrummanTurbo-CatModelA/B/CPacificAerospace750XIPZI-OkeciePZI-106TurboKrukSchweizerAg-CatG-164B/DTurbineThrushModel510PPT6A-35787eshp750shpBlue35JetPROPDIXPT6A-36783eshp750shpPT6A-38801eshp750shpPT6A-110502eshp475shpPT6A-112528eshp500shpPT6A-114632eshp600shpPT6A-114A725eshp675shpCessna208CaravanPT6A-116736eshp700shpPT6A-121647eshp615shpPT6A-135787eshp750shpBeechcraftKingAirF90-1/C90GT/C90GTi/C90GTxBlackhawkXP135ACheyenneSeriesBlackhawkXP135AConquestIBlackhawkXP135AKingAir90SeriesCessnaConquestIIancairEvolutionSilverhawk135/StandardAeroC90/E90StandardAeroCheyenneSeriesStandardAeroKingAirF90T-GAviationSuperCheyenneVazarDash3TurbineOtterMediumequivalentshaftvariantapplicationsshafthorsepowerhorsepowerPT6A-40749eshp700shpPT6A-41903eshp850shpBeechcraftKingAir200/B200PiperCheyenneTTT/TTTAPT6A-42903eshp850shpBeechcraftC-12HuronFBeec...
