MiG MFI / I-90 - MiG 1.44 / MiG 1.42

overscan (PaulMM) · 23 June 2006

Well, we all know the 1.44 demonstrator. But how did Mikoyan arrive at this configuration? What was the design evolution? What might the production 1.42 look like?

What about the Sukhoi and Yakovlev designs?

First- from Yefim Gordon's Nowe Su i MiG published in Polish by PKL, a TsAGI originated diagram showing a notional "conventional fighter" and two new designs, which appear somewhat like Mikoyan and Sukhoi's MFI designs.

What seems to be a (CGI?) illustration of an MFI test model, somewhat like a Soviet "HIMAT".

DM5.12 MODEL

Weight range	480-520 kg
Altitude range	500-7000 m
Speed range	40-150 m/sec
Experiment duration	150 sec
Number of recorded parameters	128

Pneumatic control surfaces actuators;
Start from a Mi-8MT carrier helicopter;
Landing with a triple-canopy parachute cluster and airbag shock absorber.

The operations were conducted during 1986-1992.

The models had the modular design concept. The versions of aerodynamic layout permitting to realize controlled high-angle-of-attack flight under the full airflow breakaway were completed with these models. The problems of aerodynamic and gas-dynamic control methods combination, control system structure and laws were investigated during the flight tests at supercritical angles of attack, under the stall and spin conditions.

The obtained research results allowed to receive a series of advanced aerodynamic layouts for high manoeuvering aircraft.

Alex (paralay) has got a good answer:

PS: Look at the trailing edge technical solution

Matej · 23 June 2006

Yakovlev design is described in Jefim Gordon´s Sukhoi S-37 and Mikojan MFI book at pages 9 and 10 (I have it in my language mutation, so this can differ). Refused because its one engine configuration.

More pics of Yak MFI.

I'm not convinced your drawing is accurate in this case, Matej.

The best what I can do without any proven dimensions and only with photos from different angles. The same like with my MiG izdelije 33 drawing.

I'm not criticising, it just doesn't quite "feel" correct compared to the photos.

That's in fact illustrations from TI TzaGI reprinted from AIAA paper No.74-970

Regarding 'interesting techincal solution' - he mean, in fact, bunch of dozen aerodynamic control surfaces, but I'm not sure - may be, 1.42 would have all that novel jet flaps.

Do not hesitate to do that. Any constructive criticising is welcome. Where do you see differencies? Maybe i can redraw it.

Regarding to production version of MiG MFI (1.42), it is known that it should have double delta wing, refueling probe, wedged air intakes, rounded dielectric radome, some communication antenas, FLIR and a bit redesigned bomb bay. But the question is, if it is enough. These expectations are based only on two test flights. Maybe if the test program goes well, there should be a lot of another improvements.

overscan (PaulMM) · 23 June 2006

These pictures (from Paralay's site) appear to show the TsAGI test model which was seen by visiting French engineers and others in the early 90s and which generated the first speculative 3 views of S-32.

Matej · 23 June 2006

Just imagine the engine that they were going to use. Sojuz R-179-300 with 200,1 kN of thrust!! More thant JSF powerplant.

Over here modelers are awaiting 1.44 to be loaned to Monino nearest time to count all rivets.
Test program went nowhere. Last thing I remember Saturn returned AL-41F from MiG as MiG could not pay for them.

Or another example. Before the design/projection with all of known today aircraft with the sweepforward Of s-37 golden eagle "(in the working drawings it was named Su-27KM, which by itself about the much tells), was executed project with the complete (!) set of the working documentation of experimental single-engine aircraft with the wing with the sweepforward S-22. I on one of the solemn conferences (apropos some of anniversary) chief designer Mikhail Petrovich Simonov, enumerating achievements OKB during the accounting period, said exactly the following: "it's completely finished design with the release of the trash bin working documentation* of the supersonic aircraft, equipped with the forward swept wing. These works made it possible to collect experience and they make it possible for us to go further "

*trash bin working documentation - kinda of brain training exericise with zero metal cut in result, for designers to not stop their minds working

That really isn't saying anything regarding engine performance. There are alot of engines more powerful than other engines. The real metrics are the thrust to weight ratio of the engines, the thrust levels they can operate at for a given amount of time, and their life cycles and efficiency. The Russians build good engines, but they still don't have anywhere near the life cycles of the U.S. engines. I'm sure they're getting better, though, as that is one of the major drawbacks to Russian combat aircraft on the market, even considering their much lower prices.

I'm just looking forward to seeing what the T-50 will <i>actually</i> look like and what MiG's MiG-29 replacement is going to look like, since they are once again going with a high/low mix, in terms of size; i.e. the T-50 is replacing the Flanker (fighter variant) and the new MiG will replace the Fulcrum. I have to wonder if they will look at making a medium bomber out of the T-50 or if that is something that won't happen for another twenty years since the Su-34's are just now going into limited production.

Famous shot, but here it goes in much better quality than before.

flanker · 20 March 2008

Helo, i did a search and found a lot of interesting Su-47 pictures, but if someone got more rare ones, i will appriciate.

Same goes with MiG - 1.44.

Regards, Anton.

Hello Matej, i actully have that book. But you know, i cant get enough of Berkut and MiG 1.44. And that book was realesed in 2001, so it is 7 years old. In that time it should be more and newer pictures of especily berkut...So if someone have, post it here! ;D

Thanks, have most of them, only couple that i didnt have.

SOC · 29 March 2008

The jet in the pictures above is labeled Bort 01. Does anyone know if it was numbered Bort 144 before or after it flew?

I have never seen it with flag russian flag on fin, and 144 bort number.

flateric · 31 March 2008

...and now you can. '144' and tricolor was added after first flight, maiden flight was with '01' number at intake

flanker · 1 April 2008

Oh, thanks, never seen those before! Do you know where plane is now, or when pictures with 144 bort was taken? What year. (i understand that they were taken after first flight)

I thought that at least we had enough money for more than one 15-inch LCD display on 5th generation fighter, Sasha...

paralay · 28 November 2008

To me it the person told seeing breadboard model of a cabin - one big LCD display.

Trident · 29 November 2008

Paralay beat me to it - I was also going to point out that this purpoted 1.44 panel looks a lot like the Su-27SM cockpit...

Kim Margosein · 29 November 2008

Don't worry, Flateric. The 15" LCDs will be marked down 50% after Christnas

overscan (PaulMM) · 29 November 2008

It we are talking about 1.44, that makes a lot of sense. You wouldn't expect a full glass cockpit in that demonstrator at that point in time.

flanker · 30 November 2008

Awesome pictures Flateric. Does anyone know the faith of MiG-1.44? Where is it now?
