PAF J-10C News, Updates and Discussion

[SQ8]

With or without reciting the Divinely Blessed Battle Chant of the Fighter Pilot? Many of the exact figures of jets currently in service remain classified, and routine scrambles are intentionally toned down to mislead estimates of true wartime performance.

Exact figures may be classified - but physics isn’t. Air density reduces with altitude which means lesser lift and reduced engine performance as you go higher and higher so your initial hot rod performances start dropping off. Modern turbofans mitigate engine performance but they cannot magically create more air molecules at 30000ft to have them keep flowing around your wing pushing you up via newtons second law.

Of course your point is valid. The combination of lift and engine performance changes also means careful calibration and use of flight controls too. Getting there is only half the battle. Keeping it there to do what one needs to do is an even more complex problem. The narrow difference between top speed and stall speed of the U-2 at its designed altitude is a great example.

 

[MastanKhan]

Nope - its record is 50kft in 2min.

There is a difference between rate of climb - and time to altitude

The rate of climb is at sea level - so when the F-104 takes off its capable of going at 50000ft a minute. But that is not what happens - as it climbs and the air loses density at altitude this rate drops significantly.

Hi,

Lessons in physics---.

Hi
so if we all agree to 59k/sec is it with load
or without load probably clean sheet without
any fuel tanks too
thank you

If it is 59k/sec then it is a star wars spaceship

But

The max climb at sea level are figures that are calculated are special cases with a clean airplane or minimal payload and fuel fraction.

That'll kill the pilot for sure.

That'll kill the pilot for sure.

Its a starship - probably has inertia compensation

Nice catch. Does that mean my "cover" is blown as many suspected?

It was already blown for the cultists who don't share your opinions.

Back on topic, that difference I mentioned earlier for the U2 at 70k feet was only ten (10) knots. A stall at that speed or exceeding the VNE would probably result in a breakup of the aircraft. Now let's think about the planes like the J-10C and any others being compared and how they would fare. The F-15 scooted up very high too, but that was designed to fire an anti-satellite missile and then head back, vewy vewy cayfully.

Bonus facts: The space shuttle took about 70 seconds to reach 50k feet. The Saturn V took about 90 seconds to get past 50k feet.

(BTW, I have never had any cover. I am WYSIWYG.)

Beautiful Illustration of what we will witness in near future! J-10CE and JF-17C flying together over Northern Pakistan. With similar armament & technologies but differing flight performance, the duo will complement each other to form strong deterrent aerial defence of Pakistan.
