D-436
D-436-148 turbofan engine for An-148
Type	Turbofan
National origin	Soviet Union/Ukraine
Manufacturer	Ivchenko-Progress
First run	1985
Major applications	Antonov An-148 Tupolev Tu-334 Beriev Be-200
Developed from	Lotarev D-36

The Progress D-436 is a three-shaft high by-pass turbofan engine developed by the Ukrainian (then Soviet) 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.

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] This variant produces about 16,500 lbf (73,000 N) of thrust.^[5] It 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 18,070 lbf (80,400 N) of thrust and is used on the Tu-334-100D and the Tu-334-200D.^[6]

D-436TP

• The "TP" variant was developed for use in the Be-200 amphibious aircraft. This variant produces the same 16,500 lbf (73,000 N) of thrust as the "T1" model.^[7]

D-436T3

• The "T3" variant added a booster section behind the new wide-chord fan and had a maximum thrust around 21,000 lbf.^[8] The T3 variant was also considered for the Il-214, but the aircraft's thrust requirements exceeded the max engine thrust of 21,000 lbf (93 kN).^[9]

D-436-148

• The "-148" variant was developed specifically for the An-148.^[10] This version is derated to 15,000 lbf (67 kN) of thrust for longer engine life^[11]

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 26,500-30,000 lbf class.^[12]

Derivatives

AI-436T12

• This derivative engine is being designed for use on the MS-21. It is projected to produce 26,450 lbf (117 kN) of thrust.^[13]

Applications

• Antonov An-148
• Antonov An-72/74
• Beriev Be-200
• Tupolev Tu-334
• Yakovlev Yak-42M
