NOTE: The M250- -C20R/1 se ries engine s contain eith er a large compr essor scr oll or a reduced scroll. A M250- -C20R/1 engine assembly contain ing a large compres sor scroll (single port customer bleed) is identified as P/N 23034148.
A M250- -C20R/1 engine assembly containing a reduced scroll (dual port cust omer bleed) is identifi ed as P/N 230382 00. For illustra tion purpos es, the reduce d scroll engine configur ation P/N 23038200 will be referred to as M250-C20R/1(RS) throughout this manual. NOTE: The M250- -C20R/2 Ser ies engine (P/N 2303 5212) has a Sundstr and/Pe sco, Argot ech/TR W or CECO fuel pump assembly. A M250- -C20R/2 engine assembly (P/N 23053265) has a CECO suction fuel pump. For identification purposes, the M250- -C20R/2 engine with a CECO fuel pump will be identified as M250-C20R/2(SP) throughout this manual.
NOTE: The M250- -C20R engine (P/ N23033 373) is the same as the M250- -C20R/1 (RS) exce pt that the C20R gearbox has a kidney pad housing, impending by-pass oil filter indicator, and the ignitio n exciter is airfra me mounted. A M250- -C20R engine assembly with a rear mount, two 6 cubic inch accum ulator s and a double check valv e is identifie d as P/N 2305959 7. For identification purposes, this second M250-C20R engine assembly will be identified as M250-C20R(ST).
NOTE: This manual addresses M250- -C20R, M250- -C20R/1, M250- -C20R/2 and M250- -C20R/4 en- gines. For additional information concerning M250- -C20R series engine designations or air- frame applications, refer to M250-C20R CSL 4002. Components The major engine components are a compressor, combustion section, turbine, and power and acces- sory gearbo x. Compressor The compressor assembly consists of a compressor front support assembly, compressor rotor assembly, compr essor case assembly, and compressor diffuser assembly. Air enters the engine throug h the compre ssor inlet and is compressed by four axial compresso r stages and one centri f- ugal stage. The compres sed air is dischar ged through the scroll type dif fuser into two ducts which convey the air to the combus tion section.
Co mb us ti on Se ct ion The combustio n section consists of the outer combustion case and the combus tion liner. A spark igniter and a fuel nozzl e are mounted in the aft end of the outer combus tion case. Air enters the single comb ustion liner at the aft end, through holes in the liner dome and skin. The air is mixed with fuel spraye d from the fuel nozzle and combustion takes place. Combu stion gases move for- ward out of the combustion liner to the first-stage gas producer turbine nozzle. T ur bi ne The turbine consists of a gas producer turbine support, a power turbine support, a turbine and exhaus t collector support, a gas producer turbi ne rotor and a power turbine rotor. The turbine is mount ed be tween the combusti on section and the power and accessor y gearbox.
The two-stage gas producer turbine drives the compressor and accessory gear train. The two- -stage pow- er turbine furni shes the output power of the engine. The expanded gas dischar ges in an upward direction through the twin ducts of the turbine and exhaust collector support.
