MiG-21 precursors and developments

IIRC, MiG-21PD was a testbed for the lift engine installation installed in the MiG prototype codenamed Faithless/

Hi!

question: Since the ye 7 seem to be the prototype for the PF variant, was it the prototype used to test other such as the R and if not do we have any drawing or pic of the corresponding protoype? I'd like to know how similar/different they are from the production model (verry tempted to start modern jet model with a what if Ye 7 using eduard mig 21).
Thanks for your answer!

Yes the Ye-2A was going to be put in service as MiG-23. Then the Ye-8 was going to be MiG-23. Finally we get to the actual MiG-23. Third try.

My dear PaulMM,

actually there was four attempts,Ye-2A first,Ye-50A second,Ye-8 third and
the MiG-23 fourth (finally).

Fourth try, actually. The Ye-152M was also believed to be the MiG-23 at one point; hence the old 1/144 kits by Crown.

Ye-152M was believed to be the MiG-23 in the West, but Mikoyan don't seem to have used MiG-23 for it.

Ye-50A was a Ye-2A derivative and was called MiG-23U. This was still the 1st MiG-23.

they wanted to make the mig-21 lift vertically by putting two smaller engines in the middle, but that would increase the size of the mig-21, so they gave up.
Maybe because there was not enough space for fuel, but also increased weight due to the two engines behind the pilot

This is a flying stand for testing lifting engines, its landing gear does not retract. It was created as part of the MiG-23PD program - short takeoff and landing fighter

I think they rejected the s wings at a 45 or 55 degree angle because the E-2 developed speeds of up to Mach 1.7, so delta wings were adopted to achieve the required speed of Mach 2.By the way, in the last test, the MiG-E2 reached a speed of 1930 km/h.
