|D-436-148 turbofan engine for An-148|
|National origin||Soviet Union/Ukraine|
|Manufacturer||Ivchenko-Progress, UMPO and NPC Saljut|
|Major applications||Antonov An-148|
|Developed from||Lotarev D-36|
The Progress D-436 is a three-shaft high by-pass turbofan engine developed by the Ukrainian company Ivchenko-Progress, and manufactured by Motor Sich in Ukraine. 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. 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 "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.
- The "M" variant was proposed for use on the Yak-42M.
- The "T1" variant is used on the Tu-334 and has been offered for use on the in-development Tu-414. See detailed specifications below. The variant was also proposed for use on the now-defunct An-174.
- The "T1-134" variant was proposed as a replacement for the engines on the Tu-134.
- The "T2" variant is uprated to 80 kN (18,000 lbf) of thrust and is used on the Tu-334-100D and the Tu-334-200D.
- 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.
- The "T3" variant added a booster section behind the new wide-chord fan and had a maximum thrust around 93 kN (21,000 lbf). The T3 variant was also considered for the Il-214, but the aircraft's thrust requirements exceeded the max engine thrust of 98 kN (22,000 lbf).
- The "-148" variant was developed specifically for the An-148. This version is derated to 67 kN (15,000 lbf) of thrust for longer engine life.
- The "TX" variant uses the same core at the "T3", but includes an updated turbine and a geared fan. It is in the 117–135 kN (26,000–30,000 lbf) class.
- This derivative engine was designed for use on the Irkut/Ilyushin MC-21. It was projected to produce 117 kN (26,000 lbf) of thrust. Irkut has since replaced the AI-436T12 with the 137.89 kN (31,000 lbf) Aviadvigatel PD-14.
