Progress D-436

The Progress D-436 is a three-shaft high by-pass turbofan engine developed by the Ukrainian company Ivchenko-Progress. 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.[1] Several variants have been developed and are currently in service with a variety of aircraft.

Developed from Lotarev D-36

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.

Variants
A Progress D-436 installed on an Antonov An-158
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[2]
D-436M
  • The "M" variant was proposed for use on the Yak-42M.[3]
D-436T1
  • The "T1" variant is used on the Tu-334 and has been offered for use on the in-development Tu-414.[4] 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 Tu-134
D-436T2
  • 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.[5]
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 93 kN (21,000 lbf).[6] The T3 variant was also considered for the Il-214, but the aircraft's thrust requirements exceeded the max engine thrust of 93 kN (21,000 lbf).[7]
D-436-148
  • The "-148" variant was developed specifically for the An-148.[8] This version is derated to 67 kN (15,000 lbf) of thrust for longer engine life[9]
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 117–135 kN (26,000–30,000 lbf)class.[10]

Derivatives
AI-436T12
  • 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.[11] Irkut has since replaced the AI-436T12 with the 137.89 kN (31,000 lbf) Aviadvigatel PD-14.
