Developed from Lotarev D-36

The Progress D-436 is a triple-spool high-bypass turbofan engine developed by the Ukrainian company Ivchenko-Progress, 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]

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 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. [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 93 kN (21,000 lbf). [9] 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). [10]
D-436-148
The "-148" variant was developed specifically for the An-148. [11] This version is derated to 67 kN (15,000 lbf) 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 117–135 kN (26,000–30,000 lbf) class. [9]

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

The Yakovlev Yak-42 is a 100/120-seat three-engined mid-range passenger jet developed in the mid 1970s to replace the technically obsolete Tupolev Tu-134. It was the first airliner produced in the Soviet Union to be powered by modern high-bypass turbofan engines.

The Aviadvigatel PS-90 is a Russian high-bypass commercial turbofan rated at 16000 kgf thrust. It powers Russian airliners such as the Ilyushin Il-96 and the Tupolev Tu-204/Tu-214 series and transport aircraft such as the Ilyushin Il-76. It is made by the Russian aircraft engine company Aviadvigatel, which is the successor of the Soviet Soloviev Design Bureau. "PS" are the initials of Pavel Soloviev.

<span class="mw-page-title-main">Propfan</span> Type of aircraft engine

A propfan, also called an open rotor engine, open fan engine or unducted fan, is a type of aircraft engine related in concept to both the turboprop and turbofan, but distinct from both. The design is intended to offer the speed and performance of a turbofan, with the fuel economy of a turboprop. A propfan is typically designed with a large number of short, highly twisted blades, similar to the (ducted) fan in a turbofan engine. For this reason, the propfan has been variously described as an "unducted fan" (UDF) or an "ultra-high-bypass (UHB) turbofan".

<span class="mw-page-title-main">Tupolev Tu-334</span> Airliner by Tupolev

The Tupolev Tu-334 was a Russian short-to-medium range airliner project that was developed to replace the aging Tu-134s and Yak-42s in service around the world. The airframe was based on a shortened Tu-204 fuselage and a scaled-down version of that aircraft's wing. Unlike the Tu-204, however, the Tu-334 has a T-tail and engines mounted on the sides of the rear fuselage instead of under the wings. With the nationalisation of the Russian aircraft companies in 2009 to form United Aircraft Corporation it was decided not to continue with the programme.

<span class="mw-page-title-main">Kuznetsov NK-93</span> 1980s Soviet propfan aircraft engine

The Kuznetsov NK-93 was a civilian aircraft engine, a hybrid between a turbofan and a turboprop known as a propfan. The engine was also unique in having a separate duct around the contra-rotating propellers, as most other propfans are unducted. Once described in a respected aviation encyclopedia as "potentially the most fuel-efficient aircraft jet engine ever to be tested", the NK-93 was targeted for derivatives of Soviet/Russian airliners such as the Ilyushin Il-96, Tupolev Tu-204, and Tupolev Tu-330. Five in-flight engine tests were conducted on the NK-93 from December 2006 to December 2008.

The Progress AI-22 is a turbofan engine, developed by ZMKB Progress, Motor Sich JSC, KMPO and KAPO.
