Great pics!
I've seen pics from the rear on another forum, with a person standing close by, and the engine cans on the rear are massive.
You get a distinct impression of the power and speed intended for this big but sleek beast.

For me not to the weibo-main page but to Songbird's page and how he drew that artwork based on Paralay's 3-side drawing ...

[Lascaris]

A probably belated question but how accurate is the 5th generation description being tossed around for the MiG MFI? I could be wrong but the design doesn't look particularly stealthy to me, much closer to the European 4.5 gen fighters or Silent Eagle probably?

 

[GARGEAN]

"Xth generation" is mostly marketing term, being bend here and there when needed. As example - previously it included supercruise and supermaneuverability when determined by LM. Then F-35 appeared.

 

[riggerrob]

Nice pics in that link.


A question....are the engine intakes and exhausts covered on static displays as a matter of routine/for health and safety reasons?
I assumed that it was there to protect the aircraft and its engines.
The 1.44 in the photos linked by Lancer21 above has all the covers...were the engines left in the aircraft after its two (reported) flights?


Wouldn't that be surprising, considering the advanced nature of the original AL41?

Standard practice (airlines, military and commercial) is to plug pitot tubes, intakes, exhausts, etc. when parked to prevent foreign object debris, birds’ nests, etc. Canopy covers are commonly used on aircraft parked outside.

This was posted to ausairpower net back in 1998 on how to make the i-44/42 stealthier.

A curious aspect of the various Russian reports are statements in which the aircraft is claimed to have RCS performance competitive with the F-22A. Even cursory analysis of the MFI design indicates that this cannot be the case. In particular the inlet and nose layout will be a major source of broadband wide angle RCS which the application of radar absorbers is unlikely to remedy. The beam aspect RCS will also be problematic, due to the vertical tails and keel surfaces, ventral wing stations and upper fuselage geometry. The absence of chining altogether on the nose will also contribute to beam and forward sector RCS.

The conclusion which can be drawn is that the MFI may outperform the Eurocanards for RCS performance if radar absorbent materials are used generously, the nose chined, the fuselage wing interface and spine blended, and internal weapons carried. It will never be competitive with the edge aligned, faceted, and chined F-22A design (or the chined and blended YF-23 ATF demonstrator).

1, The first picture is of the i-44 technology test aircraft.
2 The second picture is of the aircraft carrier fighter just shown in model form at MAKS it looks like mig had those particular RCS upgrades in mind already possibly for the i-42 production fighter from the 90's. Big question is do you think Mig would have stuck to the euro style air intake of the i-44? The new intakes look like they give more room for internal weapons bay. I see nose chines, better upper fuselage geometry, spine blending on the new design model .

 

[Dreamfighter]

If it ever gets on a flight-line (or flight-deck): I would suggest 'Facelift' as NATO-reporting name.

 

[Empire]

My take on the Mig I.42 Foxglove is they would have cleaned up the fuselage as they did with the model at MAKS to lower the RCS. Add a stealthier radome that is a chine for the nose (same as the model). I think they would keep the euro fighter style air intake even though it would impinge the internal weapons bay but they could add a stealthy smiley face to it just like the Typhoon. I mean the soviets had many spies in the West German aerospace industry in the 80's and 90's they probably had the information on how to lower the RCS of the intake if they already didn't know how to do it themselves.

 

[kaiserbill]

The operational version (1.42) was to have the different, wedge shaped ventral intake, as shown earlier in this thread.

Knowing how to lower RCS in principle doesn't take spies - it simply takes professionals in this field, supported with necessary level of fundamental science and computing power. Soviet Union (hence early Russian Federation) easily had all 3.
It isn't like principles of radio wave propagation are a mystery hidden on open forums, unavailable to anyone else.

Particular technologies and engineering solutions may (and always will) be borrowed when suitable, but this happens on a far "lower" level than internet discussions typically touch.

The operational version (1.42) was to have the different, wedge shaped ventral intake, as shown earlier in this thread.

While 1.42 was intended operational variant, it wasn't where this design ended. This model matches rumors on 1.46 pretty well, for example.

 

[Empire]

Yes the euro fighter intake has a wedge shaped ventral in the intake. picture #1
Why is the wedge in picture 2 so thick and why dose it extend so far forward seems to serve no purpose. In a turn looks like it would distort the airflow into the inlet its so far forward. Not to mention a certain degree off the nose it becomes a radar trap. Thats just my feeling on it i'm sure i'm way off. lol

I got this from a russian article by Viktor MARKOVSKY : aircraft (i.44) is equipped with a ventral air intake, divided into two sections (each serves its own engine). The air intakes have an upper adjustable horizontal wedge and a lower tilt lip for smooth inlet flow control (the F-22 is equipped with non-adjustable, two-stroke air inlets optimized for supersonic operation). The design of the entrance device provided for 1.42 features side bevels and a vertical central wedge, which are more advantageous in terms of stealth.

https://khai.edu/assets/files/1_2014.pdf a history from Khai about the subscale flight testing program. It’s mostly older planes but it mentions the MFI aircraft and how the subscale testing was done.

 

[overscan (PaulMM)]

01/16/1989 By the decree of the Central Committee of the CPSU and the Council of Ministers of the USSR, on the basis of the branch research laboratories of the Kharkov Aviation Institute AGD-3 and ONIL-3, the Research Institute for the Problems of Physical Modeling of Aircraft Flight Modes (NII PFM KhAI) was established. Before the creation of the scientific research institute, the collectives of the KhAI laboratories had to go through a long and difficult path of recognition and proof of the relevance of the methodology they had mastered for researching new aviation technology using dynamically similar large-scale flying models. The first flights on the LL-17 flying laboratory in 1973 should be considered the beginning of work on the study of non-stationary flight regimes of aircraft on flying models.A report on their results was sent to the USSR Ministry of Aviation Industry and the country's aviation design bureaus with a proposal to use physical modeling on models of new aircraft created by them. Interested in the proposal of the OKB im. ON. Sukhoi and OKB im. A.I. Mikoyan, but if the first is active, then the second, at first, in the role of an observer. OKB im. ON. Sukhoi handed over to KhAI a model of the Su-7B aircraft on a scale of 1: 5 as a surface standard and, on an initiative basis, the KhAI began to work on the design and construction of a dynamically similar model of this aircraft. The general management was headed by O.R. Cheranovsky, and for the implementation of the project several groups were organized, led by S.A. Yashin, V.D. Bely and N.G. Shirt. The model project was based on S.A. Yashin. Customers helped with some materials and components. In the process of work, new materials, technologies, approaches were developed and introduced. For 1974-75. two models of the Su-7B aircraft were built, on which the Su-7B aircraft performed 12 flights. The characteristics of the model obtained in these flights completely coincided with the aerodynamic characteristics of the aircraft, which made it possible to proceed to research on models of new aircraft created in the country. At the end of 1978, the branch laboratory ONIL-3 was created at the KhAI to study combat fighters created by the OKB im. ON. Sukhoi and OKB im. A.I. Mikoyan. The head of work for the OKB im. ON. Sukhoi was appointed S.A. Yashin, according to the OKB them. A.I. Mikoyan - V.D. White. Intensive work began on researching the Su-27 and MiG-29 aircraft, fine-tuning the structure in order to obtain the best aerodynamic characteristics. When creating the Su-27 and Su-35 aircraft, 55 were performed on large-scale flying models! design changes and improvements with subsequent verification of their feasibility and effectiveness in the flight experiment. You can imagine what a huge amount of money would have to be invested if all these improvements were carried out on the plane, and not on the models. The MiG-29 aircraft and its flying model This is a joint work of specialists from the OKB im. ON. Sukhoi, OKB im. A.I. Mikoyan, Kharkiv Aviation Institute, TsAGI and Flight Research Institute. MM. Gromova gave the country the world's best Su-27 and MiG-29 fighters. By the way, the famous aerobatics figure "Pugachev's Cobra" was first performed on the MiG-29 model in the study of the super-maneuverability of the aircraft, and then performed on the Su-27 aircraft by test pilot V.G. Pugachev. Under the leadership of A.I. Ryzhenko, on the Su-7B models, work was carried out to study the flutter, as well as the survivability of the aircraft during combat damage. In 1986, the staff of the laboratory was increased, and the KhAI received an order to work with the EMZ named after V.I. V.M. Myasishchev on the M-55 high-altitude aircraft, these works The start of the Su-27 aircraft model was headed by V.A. Yatsenko. In 1987, a model of the M-55 aircraft was built, on which flight tests were carried out until 1993. On the model, the modes of stall and spin of the aircraft were investigated with the provision of similar deformations of the bearing surfaces. As a result of flight studies, the boundaries of the beginning of the stall of the aircraft were determined, the values of the angle of attack of the M-55 "Geophysics" aircraft permissible in operation were clarified, and the methods for getting the aircraft out of a spin were worked out. One of the models of this aircraft was built using the "Stealth" technology with a special coating to reflect the beams of ground surveillance equipment, it was called the EPR LM-55. 1986-1987 our team has started building large-scale flying models of the aircraft of the future, i.e. to the 5th generation fighter aircraft. Models SLM22, SLM32, DM5.12 were built, on which flight tests were successfully performed. The elimination of the risk to the life of the test pilot, the reduction in the development time of new aircraft and the relative cheapness of the research method using dynamically similar models played a role in determining a leading role in the creation of research institutes. In the future, it was planned to widely introduce this method into the aviation industry and use it in the creation of all types of new aircraft created in the Soviet Union. Giproaviaprom has started designing research and production buildings for the Research Institute of PFM KhAI. All relevant building permits for the buildings have been obtained. Using large-scale flying models, the aerodynamic characteristics of aircraft were investigated: Su-7B, T-10, Su-27, Su27UB, Su-47 (Berkut), KhAI-70, Su-35, MiG-29, MiG-29UB, MiG- 29C, 4 January 2014 1.42, M-55 (Geophysics). In some years, up to 150 people worked at the institute, which indicates the scale of the work being done. And each of the employees made his contribution to our common cause, wherever he worked: design engineer, production worker, laboratory assistant, builder, supplier. They all deserve thanks. For their personal contribution to the development and implementation of research methods for new aviation technology, they were awarded the State Prize of Ukraine: V.D. Bely, A.V. Betin, A.I. Ryzhenko, V.I. Ryabkov, S.N. Sadovnichy, O.R. Cheranovsky, V.A. Yatsenko, S.A. Yashin. Many employees of the institute were awarded with certificates of honor of the USSR Ministry of Aviation Industry. t Unfortunately, due to the collapse of the Soviet Union, all work on the further development of this unique method of researching aviation technology was curtailed. The last tests of the SLM32 model were carrout in 1997. ied It should be said that a similar method of researching new technology in those years was used only in the United States.

Used AI processing to increase resolution of these tiny pics. Results are variable but SLM-22 pic is quite nice.

Dm 5.12 looks very different from the 1.44 and 1.42, however the model is described as modular like HiMAT was ment to be. The Mig-29 page mentions something similar. I’m curious if that render is actually representative of an MFI design or if it was a placeholder given how secretive the program was. Khai’s website says flights were being done till 1992 when the Mig 1.44 was being built.

If it’s a real cad model and you have the whole aircraft, and aerospace engineer could do a CFD study on it. It would be awesome to build a flight model for a flight simulator.

Not yet, but I'm working on it

 

[Erdosain]

Are these two wind tunnel models part of the MFI/I-90 program or are they both later studies? The second looks very similar to the MiG 1.44

 

[paralay]

The multiparametric "Lamprey" model was made in TsAGI in the early nineties. The MFI MiG 1.42 was already put into production in 1992 - 1994.
