| D-436-148 turbofan engine for An-148 |
The Progress D-436 is a triple-spool high-bypass turbofan engine developed by the Ukrainian company Ivchenko-Progress during the Soviet era, and manufactured by Motor Sich in Ukraine.[1] It was initially developed to meet the requirements for late versions of the Yakovlev Yak-42 and the Antonov An-72 in the 1980s. The engine first ran in 1985 and was subsequently certified in 1987.[2] Several variants have been developed and are currently in service with a variety of aircraft.
Design and development
The D-436 engine was developed as a follow on to the Lotarev D-36. The engine took several of its design features from that engine and another Progress engine, the Progress D-18. The D-436 incorporated an updated, higher RPM fan, a lower emissions combustor, and new compressor sections. Several variants of the engine incorporate a FADEC.
The Motor-Sich plant in Zaporozhie, where the assembly line for D-436 engines was located,[3] was destroyed by Russian forces in late May 2022 following the 2022 Russian invasion of Ukraine.[4]
Variants
.jpg){kind=link}
- D-436K
- The "K" variant was the initial model of the engine. It had a bypass ratio of 6.2 and a pressure ratio of 21.0. Proposed for use in the defunct Antonov An-71.[5]
- D-436M
- The "M" variant was proposed for use on the Yak-42M.[6]
- D-436T1
- The "T1" variant is used on the Tu-334 and has been offered for use on the in-development Tu-414.[7] See detailed specifications below. The variant was also proposed for use on the now-defunct An-174.
- D-436T1-134
- The "T1-134" variant was proposed as a replacement for the engines on the Tupolev Tu-134.
- D-436T2
- The "T2" variant is uprated to Script error: No such module "convert". of thrust and is used on the Tu-334-100D and the Tu-334-200D.[8]
- D-436TP
- The "TP" variant is a specific "maritime" corrosion-resistant version developed for use in the Be-200 amphibious aircraft. This variant produces 7,500 kgf (16,534 lbf) each.
- D-436T3
- The "T3" variant added a booster section behind the new wide-chord fan and had a maximum thrust around Script error: No such module "convert"..[9] The T3 variant was also considered for the Il-214, but the aircraft's thrust requirements exceeded the max engine thrust of Template:Cvt.[10]
- D-436-148
- The "-148" variant was developed specifically for the An-148.[11] This version is derated to Script error: No such module "convert". of thrust for longer engine life.[12]
- D-436TX
- The "TX" variant uses the same core at the "T3", but includes an updated turbine and a geared fan. It is in the Script error: No such module "convert". class.[9]
Derivatives
- AI-436T12
- This derivative engine was designed for use on the Irkut/Ilyushin MC-21. It was projected to produce Script error: No such module "convert". of thrust.[13] Irkut has since replaced the AI-436T12 with the Template:Cvt Aviadvigatel PD-14.[14]
