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。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下：VariantsPT6Ahttp:/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)PropellerSpeed(Max.
