Known as the builder of the Ivchenko (sometimes Ivtchenko) radial piston engines from the great designer Aleksandr Georiyevich Ivchenko.

-His piston engines were well known and manufactured in many of the industrialized countries under Soviet influence.

-After the division of the USSR in 1989 it was renamed "Ivchenko Progress ZMKB" and finally only "Progress".

-ZMKB are the initials of “Zaporozhye Machine-Building Design Bureau” (Progress State Enterprise).

-The activity of Ivchenko began in 1916 and after the chaos of the revolution they began to build engines such as the M-11 and M-22 (Bristol Jupiter), M-85, M-86 and M-87.

-At that time, the Head of the Design Office (OKB) in Zaporozhye was A.S. Nazarov

-Later Tumanskii and Umin passed, until Ivchenko entered in 1945.

“AI-14”

-He used the initials AI of A. Ivchenko and the AI-14 and AI-26 piston engines came out. They are still in production today.

-For example the AI-14 of 9 radial cylinders, with powers between 225 and 300 CV. The AI-26 with 9 cylinders too, but with nominal 575 CV, varying according to the series (the AI-26B 575 CV on the MIL-M-1, the same power as the AI-26W and AI-26GR).

“AI-14, side view”

-An AI-4V with 55 CV at 4,500 rpm, with 4 opposite horizontal cylinders, is known. This engine was built from 1948 to 1955.

-Another one was the AI-V. This was an AI-7 ramjet propulsion system at the tips of the rotor blades of an experimental helicopter.

-The AI-9 is a small turbine - auxiliary? - that we see in the photograph below.

“Ivchenko AI-9”

-By 1953 he got to know the Kuznetsov TV-2 engine and developed it to the TV-2T turboprop and the TV-2K turboshaft.

-The former, in turn, continued to be developed to the TV-20 (AI-20).

“Ivchenko AI-20, right side”

“AI-20, left side”

-Since 1958 when it entered production, several series have been made, such as the A and the K with 4,000 shp, the M with 4192 shp, the DK with 4190 shp, the D and DM with 5180 shp and then the DME and DMU for land vehicles.

“AI-20D”

-The AI-20 turboprop is an engine with a large 10-stage axial compressor with 4 single-shaft discharge valves (by-pass for start-up, etc.), and with a large gearbox. It has a three-stage turbine and an annular combustion chamber with 10 injectors. These engines have been mounted on AN-10 and Il-18 aircraft.

“AI-20, cross-section”

“Ivchenko AI-20M”

We obtained a cutaway drawing of the Type-K engine (possibly from the AI-20K), a successful turboprop engine in countries of Russia's orbit.

“Ivtchenko, tipo K”

-More than 15,000 AI-20 engines have been manufactured. The engines designed by the MKB (OKB) “Progress” are manufactured by Kazan Motorbuilding Plant and by Motor Sich.

-The AI-21 was used on the Yak-38.

-The AI-22 is a turbofan of 3,850 Kgf of thrust that was used on the Tu-324 and Yak-48 aircraft. It is a small fan type turbine for business or regional aircraft. It uses the core of the Lotarev DV-2.

“AI-22”

-It is of recent design -relatively- with the following maximum power performance: 8,532 lbf of thrust in one of his latest evolutions.

“Ivchenko AI-222”

-The current AI-222 too, is being developed (like the previous one) jointly by Ukrainian and Russian aviation engine construction companies, such as A.G. Ivchenko, ZMKB Progress, FSUE-MMPP, Salyut and Motor-Sich. With the participation of Baranov, among others.

“AI-222-25”

-The AI-222-25 gives from 2,800 to 3,000 Kgf of thrust varying according to the -B, -F, -FK, or -28F version.

“AI-222 variants”

-The AI-24 is a propeller turbine designed in 1960, in fact it is a power-reduced AI-20 to equip the An-24. In its different versions the delivered power varies around 2,500 shp.

“Ivchenko AI-24”

-The AI-25 is the turbofan for the small well-known Yak-25 trijet and the Czechoslovak L-39 trainer.

“AI-25”

-The AI-25 gives the order of 3,300 lbf of thrust, and the -25TL version can reach 3,790 lbf.

“AI-25, cutaway”

-In the illustration above we can see this engine's cutaway with a 3-stage fan. The design is of the basic AI-25 engine from 1965.

-Today with just one fan you get the same results. It continues with a very generous bypass duct.

-The AI-30. Under this designation the TV3-117 was prepared for several airplanes. It delivered 2,800 shp. At this time it has not entered production.

“AI-450”

-The AI-450 is a newly designed 550 shp turboshaft for light helicopters. This project by L. Martynenko was started in 1998, and is built together with Motor-Sich.

-A turboprop version of the AI-450CV is underway through Motor-Sich director, V. Boguslayev. It has a free turbine, a centrifugal compressor and inverted annular chamber.

“D-18”

“D-18”

-The D-18 engine was projected in 1977, and has a long historical journey on airline aircraft.

-It is still being built today, in the versions -T, -T1 and TR / TM. They have a single fan with two shafts. These engines have a reverse system for the fan as we can see in the illustration.

-It gives 51,600 lbf. thrust in the D-18-T version and increases to 57,320 in the -T1, to 55,777 lbf. in the -TM, to reach 60,627 lbf in the -TR version.

“D-27, PropFan”

-The D-27 is a contra-rotating turboprop of multi-bladed propellers from Ivchenko-Progress-ZMKB.

-In fact it is an impressive looking propfan. See D-27 and D-127 that will be handled later in this chapter.

“D-36”

-The D-36 is a turbofan, projected in 1977 with 6,500 Kgf of thrust.

-It is the base for the D-136 turboshaft family, the D-236 propfan, the D-336 industrial engine and the D-436 turbofans.

“D-136”

-The turboshafts are used on helicopters such as the Mi-26 with 11,000 CV on the shaft approximately.

“D-136”

The D-236 contrafan had the same power and flew for the first time in 1987. Below we see it installed on a Yak-42.

“D-236”

-The contrafan that drives the above mentioned D-27 turboprop, although it seems derived from the D-236, it is larger because it delivers 14,000 shp.

D-627
“D-27 cross-section”

-The spectacular propellers are of Aerosila's Stupino brand. This is model SV-36 with 8 front blades and 6 rear ones.

“D-27”

-For the D-27, the Stupino SV-27 model propellers are contra-rotating as we have seen above. The front propeller has eight blades, while the rear one only has six. All blades are made of composite.

-The D-127 is the turboshaft version for helicopters in a modernization and performance-increase plan, with 14,350 CV to the shaft, they can lift heavy weights, as on the Mi-26M.

-They have a modular design and are equipped with a FADEC control system.

“D-127”

-The D-627 is a high-bypass turbofan, with reverse thrust. It is based on the D-27 and delivers 26,000 lbf of thrust. Possibly for the Yak-46.

-From aviation engines, the Ivchenko Office has developed industrial engines.

“Ivchenko industrial engine”

-Industrial turbine with shaft power output for driving large generators, pumps, etc.

“Another Ivchenko industrial engine”

From Appendix 6: The AI-22 is a 3,820 Kgf turbofan designed and evolved by Ivchenko Progress and built by Motor Sich, both in Zaporozhye.

“Ivchenko AI-22”

-The AI-25 have evolved from the basic engine to the AI-25W and the AI-25T, -TL, -TL2 and -TLK.

“Ivchenko AI-25”

“Ivchenko AI-25TL”

-The Ivchenko AI-25 is not a large engine because the maximum diameter is 510 mm. Therefore it is an engine for training aircraft such as the L-39.

“Real look of the Ivchenko AI-25TL”

-We have got a better view of Ivchenko's APU engine, the AI-9, used as starter for the TW3-117 on the Mi-14 and Mi-24 helicopters. And for the TW2-117 on the Mi-8.

“The AI-9”

-The AI-9V version is a gas generator. The AI-9B gives 16 Kilowatts of electrical power output.

-The AI-26 engine does not appear in the main text. Now we have pictures of the AI-26V, that was installed on the Mi-1 helicopter. These two photographs have been taken at the Stolnok AirMuseum.

“AI-26V” (AEHS)

“Another view of the same engine” (AEHS)

-As we can see, it has a generous fan, necessary while the helicopter is in hover, so it does not advance and requires forced cooling air.

-It is visible that a rotating shaft for the main rotor sticks out from the gearbox.

-And from the Budapest Museum of Technology another very colorful photograph of the AI-20M, a large turboprop of 4,250 shp that was (and is) installed on the IL-18.

“AI-20M” (photo AEHS)

From Appendix 9: There are more AI-450 versions. Precisely at the German Aero-13 Show, the DA-50 aircraft was shown with two propulsion systems, one with the Austro AE-440 V8 piston engine, and the other with an Ivchenko AI-450-S conversion.

“AI-450-MC turboshaft”

-Both AI-450-S and S-2 versions are aimed at propeller planes. This in addition to the -TP.

“AI-450-S turboprop”

“Installed on Diamond D-50, with 5-blade propeller”

“AI-450-BP and -BP-2 turbofans”

-All AI-450 engines have the same "Core" with the same centrifugal compressor and the same combustor.
