Hi! MiG-17SN.
http://ourairports.biz/?p=942
https://forum.warthunder.com/index.php?/topic/311375-mig-17-sn-experimental/

"When the guns were fired, other unpleasant surprises occurred. For example, firing in gusts with the three weapons rotated upward or downward altered the aircraft’s flight path in the opposite direction. It was impossible to fire the cannons at all when the weapons’ slew angle exceeded 10 degrees upward unless special equipment was used to balance the angular momentum of their recoil. The setbacks suffered while experimenting with rotating weaponry on both the MiG-15 and the MiG-17 convinced the OKB once and for all that any such system would be useless if installed too far from the center of gravity in singleseat fighters. All research work in that direction was subsequently abandoned."

It is interesting that nobody had enough forethought to anticipate that before wasting resources on building it.

Obviously a rotating 'turret' in the nose was nonsense. If my memory serves me well the Americans also tried similar solutions with quite similar results (F-87, F-89, F9F).
I'm curious why the Soviets didn't use the solid nose with side intakes for a photo-reconnaissance or ground attack variants of the MiG-17 (as the Chinese did with the MiG-19/J-6 to make the Q-5). Polish designers of the Lim-5M/Lim-6 (ground attack variants of the licence-built MiG-17F) did consider such an arrangement, but they concluded that it would require a major redesign of the fuselage, which would be more costly and would make a rebuilt of existing fighters into ground attack planes impossible. Therefore the idea was dropped (unfortunately in my opinion).

The two air intakes didn't fit well with the engine layout and caused many flame outs.

Тhe problem was the large firing forces оf the gun and and poor precision perhaps reccoilless gun maybe be a better solution ?
