Most Soviet and Russian fighters have considered the take-off and landing requirements of front-line airports, so the design of the air intake duct and landing gear is very unique, such as Sukhoi series nose wheel fenders, and MiG series retractable air Road bezel.
Some people may not pay too much attention. In fact, the intake of the Jacques-130 advanced trainer is also baffled, which can be retracted during take-off and landing to avoid inhaling the gravel on the runway.
It should be noted that the inlet baffle of the Yak-130 and the MiG-29 is not yet the same. The inlet baffle of the Yak-130 is a dual-purpose board. From the beginning, it became the opening of the auxiliary air inlet, and the design is very delicate.
