While the chinese forum lore troll were saying J-20 was a Mach 2.5 mach, science triumphed, DSI have a max mach 2 speed limit with an ideal Mach 1.6, (J-20 barely will fly near Mach 2).

It also showed the 20.1 meters long fantasy was pure fantasy

this picture showed it was as big as Su-27 but chinese forum lore said it was smaller

There is a lot of discussion about the maximum speed of J20,
Some people think this is a practical Mach number, not a maximum Mach number.
Some people think that this is the data of the early 2001 unit.
And this data does not indicate what state it is, what height data,
There are many official data that are different
So the credibility is not high,
Also, the length is obviously the J20 data from the early use of the airspeed tube,
I remember someone analyzed
There are many different data for the maximum speed of the F22 air show

Didn't you often post that J20 couldn't reach Mach 2.0 and was limited to M1.8 or M1.6?🤔

It seems you were wrong. Why are you pretending you were right?

And claims that J20 was a "fighter bomber" bigger than a flanker were proved wrong long ago. Those stats and pic prove J20 is slightly shorter than the SU30 airframe at 21.2m VS 21.9m respectively.

You added a lot of Fantasy.

J-20 is not a fast design why?

well like Rafale has fixed intakes.

Pressure recovery for the DSI is around 89% by around Mach 1.7

basically all DSI intakes top up at mach 1.6. JF-17 is not fast and same applies to J-31 or F-35.
These aircraft top up at mach 1.7.
This you bro?

Do you understand what is design number for an air intake? ideally DSI have a Mach 1.6 design number after that the aircraft can reach Mach 1.8 or even Mach 2 but the risks are damage the engine or increase fuel comsumption.

Of course you do not know, most aircraft can fly faster than what you think, MiG-25s were flown at Mach 3.2 but they damaged the engines so they were capped at Mach 2.8.

F-16 theoretically can reach Mach 2+ speeds but the engine can also be damage and the aircraft is basically a 0.9 Mach aircraft with very short incursions into Mach 1.8 and very rarely Mach 2.

So is J-20 it is a Mach 1.6 aircraft but it can be flown into Mach 1.8 or even Mach 2 what you do not see is fuel will be pumped so fast its range will be reduced considerably and the engines will be operating with lots of turbulance forcing more fuel to compensate for air flow thurst

that is for ignorants read any paper on DSI intakes and the ideal design number is Mach 1.6.

Can they go faster? of course a F-14 can fly at Mach 2.7 but the damages and intake air mass conditions are not ideal.

Most aircraft are capped at an ideal Max speed, F-16 is a Mach 2 aircraft, it can fly a bit faster but it may damage the engine.

MiG-23 was flown at Mach 2.6 but ideally it has a Max Mach 2.35 speed.

J-20 is a Mach 1.6 aircraft with very short and rare incursions at Mach 2.

A relatively nice view for me of J-20

1632955880395.png


but I find nicer the Su-27 or Su-35
