Perhaps, this fighter is further development of Tairov (not Tyrov) OKO-6 twin-engine fighter.
It has been described here http://www.airwar.ru/enc/fww2/ta3.html

Transliterations

In 1940 Tairov was developed preliminary design of fighter 0K0-7 with more powerful engines and improved design of the aircraft.

Fuselage of the plane was supposed to make a wooden timber of the delta. A perfect canopy was a pilot. Front and rear provided bulletproof. Should it be a partial booking cockpit sides. Stabilizer adjustment in flight.

One of the design features of the aircraft: the central plane the aircraft was put under the fuselage at the nodes and removed from them during transport.

December 9, 1940 was approved by the Air Force at the conclusion of the draft design 0K0-7 engines AM-37 or M-90.

Appointment of aircraft - fighter-interceptor, fighter escort aircraft to combat major ground targets, easy high-speed bomber.

Conclusion on the outline sketch was made positive: "... consider a preliminary draft, to include in the plan of an experienced construction in 1941 and survivability better option with the M-90".

Yes of course, it’s the same person. But in Russian his surname is Таиров, so Tairov is the only correct spelling. Yes, in English transcription “Tyrov” can sound like [‘tairov]; but Russian words don’t obey English rules, and the transliteration from Cyrillic to Latin isn’t phonetically-based. “Tyrov” in Latin would be Тыров in Cyrillic, not Таиров anyway.

Now about OKO-7: it was actually OKO-6 (Ta-1/3) derivative, designed as interceptor fighter, escort fighter, light high-speed bomber and an aircraft operating against large ground targets. Its new features were a fuselage completely made from phenol-impregnated modified wood (so-called Delta wood – the same material LaGG-3 was made from; OKO-6 had nose and middle fuselage parts made from metal) and improved cockpit canopy. Also the center wing section allowed its separation from fuselage for better transportation (on the OKO-6 it was designed as a single unit with fuselage middle section). OKO-7 with M-90 engines was entered into 1941 prototype aircraft production schedule, as well as OKO-8 twin-engine fighter with Mikulin AM-36 engines. But the Nazi invasion and then Tairov’s death in air crash at October 29, 1941 were fatal for both these projects. Unfortunately I have no pictures for any of them.

Those OKO-2,3 appears to be projected versions of OKO-1 passenger aircraft

OKO-2 - ambulance version for 6 stretchers
OKO-3 - cargo/paratrooper-carrier

Hi all,
I'm looking for more informations about the Tairov OKO-4. According to Gunston, it would be a biplane single-seat fighter and attack aircraft, powered by single 1100hp M-88 armed with two 12.7mm BS and 100kg bombs, cancelled in 1939.

Thanks a lot.

Related to the previous topic, more questions:
Polikarpov TsKB-44 is the VIT-1? And TsKB-48 is the VIT-2?
What about Polikarpov DIT? I don't remember where I saw this last one, maybe a fake (my guess is: Dvukhmotornyi Istrebitel' Tankov or Dalnij Istrebitel' Tankov).

I can't see how this relates to Tairov... but anyway, DIT is not a typo. It appears in this list as a fighter/trainer, Polikarpov's 12th design... Haven't been able to find a picture of that project in my files yet, though... :(

Hi Visvirtusvoluntas,


do you mean the Tairov OKO-4 (Ta.2) was developed from Polikarpov DIT ?,
that's your point.

Tairov topics merged.
Ta-1 was the OKO-6, Ta-2 was the OKO-4, Ta-3 was the OKO-6bis, Ta-5 was the OKO-8... Any idea what the Ta-4 was?

And a text:

OKO-4 fighter project

In 1938, plans were made for experimental construction of a very maneuverable single-seat sesquiplane fighter initiated by designer Vsevolod Konstantinovich Tairov. The OKO-4 was a cantilever biplane of very original layout with an M-88 gearless engine. The first copy of the fighter had to be delivered for state trials in December 1938, and the second in February 1939.
Specs (preliminary draft):
  • Maximum speed (at an altitude of 7500 m): 522 km/h
  • Landing speed: 100 km/h
  • Service ceiling :eek:ver 12,000 m
  • Climb rate: 8000 m in 7.7 min.
  • Typical range: 600 km
  • Maximum range: 1000 km
  • Armament : four synchronized ShKAS 7.62 mm machine guns with 850 rounds of ammunition,
    or 2 synchronous BS-caliber 12.7 mm machine guns with 250 rounds of ammunition and two synchronized ShKAS 7.62 mm machine guns with 850 rounds of ammunition.
    Under the wings were suspended two bombs weighing 50 kg each.
At the conceptual design stage, an attack version of the aircraft was considered. However, due to the strong involvement of V.K. Tairov's works on the OKO-6 aircraft (the future Ta-3 experimental twin-engine fighter), and with the inability to produce the required M -88 engine at the time, the designer requested that the manufacturing of the OKO-4 be postponed for ten months. Shortly thereafter, the fighter was cancelled while its construction was 40% complete. One of the reasons for stopping work on the aircraft, besides the fact that the workforce was already busy with other programs, was Tairov's understanding of the fact that the OKO-4 would not be able to outperform the serious competition which the Polikarpov I-190 and the Borovkov-Florov I-207 represented, and that it would be hard to be fully consistent with the tactical and technical requirements as defined in the preliminary draft flight characteristics.

Often overlooked was the OKO-9 project, a cantilever wing monoplane heavy fighter with four M-105 or М-107 engines (depending on the source) arranged in pairs in the front end of the fuselage, with pilot and gunner seated in the middle section. I really wonder what that would have looked like, and I wish I could find a general arrangement of it...
