Isn't this just some sort of experimental Mig-21 that never went into service?

 

Yes

It mst better than MIG-21MF [Fly longer,turn faster,more loadout,maybe 2 X R-23+2/4 R-60]

I believe this was going to be a Mig-23 at some stage before requirments changed and it was used to test the radar for the 25 if I remember correctly. I doubt it had any influence on the J-10 as there is over 30yrs between the two.

The Je-8 was the planned successor of the MiG-21. It should be named MiG-23, but had nothing in common with the later MiG-23 swing wing fighters.

Je-8 was developed from the MiG-21PF. It had the same tail, the same wings, the same gears etc. It got a different nose to incorporate the new Saphire-23 radar, the later MiG-23 radar. Also was planned to implement the R-23 missile family. The air intake was build below the cockpit, 10 years before the F-16. (Is the F-16 a copy of the Je-8, could i ask with the same gestus some people always ask wheter this or that soviet plane is a copy of an american bird.)

This was neccessary, because the new engine had need a much higher air flow.

The E-8 was built in 2 prototypes and it proved much superior to the MiG-21 in all aspects of speed, accelleration, climb rate, agility and weaponary. But the engine was still "green". It had major weakpoints which cause a fatal plane crash when the first stage of the engine exploded. The problem could not be solved and at this time no other engine of this class was available. Thatswhy Je-8 project was canceled. The surviving plane was scrapped. It was not used in MiG-25 radar trials. It was much to small for it.

 

To say the chinese J-10 based on the Je-8 is as wrong as the idea, that the F-16 is a copy of the Je-8.

 

Its pitty that the Je-8 never came to the troops. It would have been a much better MiG-23 than the swing wing Floggers.

Reading accounts in the Past from the F-16 designers the Intake was going to be further forward but this caused air flow problems so it was moved back to where it ended - that being the optimal position for the best air flow to the engine I believe.

Silverbolt, the Je-8 is a plane with normal design, the J-10 is a plane of canard design. A Mirage is closer to the J-10 than a MiG.

The J-10, like other deltas, also has no tailplane like this and other MiG-21s have.

 

The Mig-21 is however unique in that like the A-4 it is one of the few tailed deltas to see widespread service.

The other major difference is, that J-10, Eurofighter, Rafale etc use their canards for maneuvering. The Je-8 canards were only stabilisers.
