普惠PT6渦槳、渦軸發(fā)動機結(jié)構(gòu)及參數(shù)

PT6系列發(fā)動機是加拿大普惠公司的產(chǎn)品，包括渦槳和渦軸變種，是當前使用最為廣泛的輸出軸功率的航空發(fā)動機之一。在美國軍用編號中，PT6的相應型號分別被命名為T74和T101。與首臺在1963年面世的450SHP軸馬力的PT6A發(fā)動機相比，如今PT6發(fā)動機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%。據(jù)了解，PT6發(fā)動機已生產(chǎn)了52000多臺，并被應用在130個不同領(lǐng)域，PT6發(fā)動機所在機隊的飛行時間已累計多達3.9億小時。在全球航空領(lǐng)域普遍進行的重要任務中都能找到PT6發(fā)動機，從救援工作到預定的客運服務，從貨運服務到要客接送，從農(nóng)業(yè)應用到軍事飛行培訓、從消防救火到搜救任務。PT6A發(fā)動機高可靠性也加速了20世紀80到90年代的單發(fā)渦槳飛機的發(fā)展。PT6A是渦槳發(fā)動機，PT6B和PT6C是渦軸發(fā)動機。PT6發(fā)動機的各變種及參數(shù)如下：VariantsPT6Ahttp:/www.pwc.ca/en/engines/pt6aPT6A家族包括了一系列自由渦輪渦槳發(fā)動機，輸出功率500-1940shp（433-1447kW）ThermodynamicPowerClass*(ESHP*)MechanicalPowerClass*(SHP)PropellerSpeed(Max.

A later mark of PT6B is rated at 981hp (731.5kW).PT6Chttp:/www.pwc.ca/en/engines/pt6cPT6CThePT6Cis a 1600 to 2300 horsepower (1190 to 1720kW) engine for helicopters and tiltrotors.PT6DPT6D-114AThe PT6D-114A is based on the PT6A-114A. The main difference is the deletion of the second stage reduction gearing and output shaft, because the engine is intended for integration with a combining gearbox incorporating power turbine governors and a propeller output shaft.Soloy Dual Pac2x PT6D-114A engines driving a single propeller through a combining gearbox, capable of independent operation.PT6Thttp:/www.pwc.ca/en/engines/pt6tPT6TTwin PT6 power units combining outputs through a gearbox for use in helicopters.ST6ST6TheST6is a variant of the PT6 that was originally developed as a powerplant for theUAC TurboTrainpower cars, but later developed as a stationary power generator andauxiliary power unit.ST6BTheST6B-62was a 550bhp (410kW) version of the PT6 developed
