The MiG-15 was not derived from the Ta 183. There's no need to repeat this well-known myth here.

But it was derived from what jet now ?
Saab 29 Tunnan ?

It was started in 1945.

I thought it was a reverse engineered RR Nene centrifugal engine !
I thought so too...it was Mig-9 that used reverse engineered BMW 003s.
Sorry and thank you.
Yak-15 and 17 used Jumo 004 reverse engineered.

Original development (except for the engine). Some elements from the MiG-9 and I-270.
Doesn't it matter to you that the MiG-15's maiden flight took place nine month earlier?

What's your take on the suggestion of development being influenced by the Pulqui II (itself a HeS 011/Ta 183 derivative)?
No because Tunnan was started in 1945.Original development (except for the engine). Some elements from the MiG-9 and I-270.

Where do you think they got the swept wings on it ?
I-270 was nothing like it.

In 1946.
And what do they have in common, besides the fact that they're monoplanes with swept-back wings and a high-mounted tailplane? (Spoiler: NOTHING) They're completely different designs. Using your logic, one could say that all airplanes are simply evolutions of the Wright brothers' aircraft, since they all have wings and an engine.
The Soviets didn't need the Saab - by mid-1949, mass production of the MiG had already begun, and it outperformed the J.29 in virtually every respect; by the time production of the Tunnan began, mass production of the MiG-15bis - with even higher performance characteristics - had already started.
All arguments regarding "which aircraft the MiG-15 was a copy of" stem solely from a lack of knowledge of the facts.
The USSR conducted its own research into swept-wing designs, for which it had the necessary facilities (wind tunnels), and several experimental gliders and aircraft were built. Undoubtedly, the results of German research could have been utilized, though to what extent is difficult to say; personally, I believe it was very limited.
The I-270 was used to test high-mounted tailplanes and to refine a two-part fuselage design with a mid-section joint for easier engine maintenance.
Design work on the IAe-27a Pulqui II began after the MiG-15 had already made its first flight.
Yup....and is nothing like Ta-183....which was not Kurt tank design in the first place ( Hans Multhopp )...it ( Pulqui 2 ) was ugly as ****. Surely Tank was over seeing the design.
Where did you get that nonsense from? I-310 flew with a Rolls-Royce NeneBut it was derived from what jet now ?

The Pulqui II was derived from the HeS 011 programme, and the aircraft itself bears a visible similarity to Design III of the programme, the alternate design of what became the Ta 183.

From what I've read on other sites, the issue with the Pulqui II was that Hans Multhopp didn't leave for Argentina with the rest of the Focke-Wulf staff. He was apparently the most knowledgeable on how to work the wing set up around a central air intake+engine. Without him, the higher risk shoulder mounted wing set up was chosen, and this lead to stability issues.

And yet, the shoulder mounted wing of the La-15 did not appear to cause flight problems. I have read the La-15 outperformed the MiG-15 but not built because the MiG-15 was far easier to build.
Not exactly. The La-15 had performance characteristics comparable to those of the MiG-15, but the MiG's more powerful engine gave it an advantage in rate of climb. The La-15's most significant advantage consisted in the absence of stability and controllability issues at high speeds, thanks to its sturdier wing and its superior build quality; however, it was more complex - the manufacturing of many parts was poorly suited for mass production. Lavochkin was tasked with designing a fighter equipped with a Derwent engine - if he had received the Nene right away, the result would most likely have been better than that of Mikoyan and Gurevich, judging by the test results of the "168" aircraft with the RD-45 (Nene).
