Then how MiG-25 maintain its stability at low speed ?
Things like MiG-23 has swing-wing to increase stability at low speed, but MiG-25 doesn't. So what method MiG-25 uses to deal with it ?
MiG-25 aerodynamic design is the standard for 4th gen. The broad hull, made by adding 2 inhale-engine to the side of the cockpit, significantly increases the G-load, and concentrates the G-load into the hull rather than the wing. That enable MiG-25 to sustain much larger G-load, which is vital for 4th gen fighter.
MiG-25 has 2 vertical tails instead of one, and the tails were put at the border of the hull. That prevents the tails from being blocked by the hull at high AoA. Su-27...37, MiG-29, F-14/15/18/22/35 learn from it.
MiG-25 has electronic-controlled air inhale, which enable the air flow to be controlled and changed in different speed, payload, and conditions. Su-27...37, MiG-29, F-14/15 learn from it.
Can MiG-25 do the job of ground-attack ? Yes, it can. FBV, computer pilot, great payload and operational range... that means MiG-25/31 do have potential for multirole characteristic, although it is not designed to do so. Later, people modified the concept of MiG-25 to suit the multirole task, and gave birth to F-15, Su-27, MiG-29.
In order to deal with the low stability at low speed, MiG-25 approached fly-by-wire, or in my language, "computer pilot". The human pilot became similar to a game player with a joystick, sends electric message to the "computer", and the "computer" does the task of driving the aircraft.
That means the computer had to be very sensitive, like a circus actor walking on a small string. That explains why it took a very long time for developing MiG-25, because it took time for maturing the computer pilot.
In that time, MiG-23 was created as an intermediate, situational solution. MiG-23 replaced the computer pilot with the swing wing. Although the swing wing gear is heavy and weak, but MiG-23 is cheap and it was a good solution to fill the gap when MiG-25 is still developing.
MiG-25 and Ye-8 set the standard for MiG-29, Su-27, F-14/15/16/18/22/35 and Eurocanard to follow, that's the fact.
Before 199x, the West still had the sight of hundreds of oils stand toghether in closed area. That means it only had vertical drilling. But Russia have angled drilling and turbin drilling long long ago.
It is your Motherland who taught all over the world how to drill oil, and it is your Motherland stands at the top of oil drilling, no matter how you hate it.
Your dear Western civilization cannot make an acceptable aerospace rocket, that's why the US still buys RD-180, and the old man Soyuz still sends satellite and consonants to the space.
And ISS has the most vital parts from Russia.
For a long time I don't understand why Vann many times tagged you in his post, and I don't understand why Werewolf dislikes your thinking in politics.
But now I can roughly see why.
