And good ol' F-15. And Su-27, Mig-29, Su-35, MiG-35
That they are all much faster, fly much higher. Happen to have much better radars. F-22 has tremendous acceleration.
No amount ofcan help you weasel out.
Ask them to participate and get shortlisted then. Did you forget that the Mig-35 did not get shortlisted? And the F-15C is no longer in production, only the strike version called F-15E is. So, nope.
All obsolete jets. Even the Su-35 and the Mig-35.
Of course F-22 has tremendous acceleration, it has a very powerful engine.
Let's see what its TWR is with full fuel.
F-22
Empty weight = 19.5T
Internal fuel = 8.3T
Thrust = 165x2 = 330KN = 33.6T
TWR = 1.20 @fuel fraction = 0.29
Typhoon
Empty weight = 11.5T
Internal fuel = 4.5T
Thrust = 90x2 = 180KN = 18.4T
TWR = 1.15 @fuel fraction = 0.28
Rafale
Empty weight = 9.5T
Internal fuel = 4.7T
Thrust, engine 1 = 75x2 = 150KN = 15.3T
Thrust, engine 2 = 83x2 = 166KN = 16.9T
TWR, engine 1 = 1.08 @fuel fraction = 0.33
TWR, engine 2 = 1.19 @fuel fraction = 0.33
AMCA
Empty weight = 12T
Internal fuel = 6.5T
Thrust = 115x2 = 230KN = 23.5T
TWR = 1.21 @fuel fraction = 0.35
Oh, and the Typhoon can supercruise at mach 1.5 in cold climates with 2 supersonic fuel tanks and 6 missiles. So can the Rafale, but at lower speeds and with only 1 tank and 4 missiles.
If the Typhoon and Rafale M can supercruise with external loads, do you really think AMCA cannot with internal loads?
The AMCA will have higher TWR with a much higher fuel fraction than the F-22.
If we bring the AMCA's fuel fraction down to 0.29, in order to match the F-22's range, AMCA will only have to carry 5T of fuel, then the AMCA's TWR will be 1.38.
In fact, the AMCA's engines will be rated higher than western engines due to our higher ambient temperature, since we are closer to the equator than they are. The temperature rating is in fact much higher for Indian conditions, at least ISA+20deg instead of the western standards of ISA+10 or ISA+15deg. It means if you bring the F-22 down to hotter climates, the thrust will actually decrease, while AMCA will retain its full thrust even in hot summers.
Even the F-22 can't compare to the AMCA, let alone the Eurocanards, and you actually want to compare Cold War relics to the AMCA?
Dude, you have a lot to learn.
Nah, he's talking about this one little parameter that the Typhoon scored over the Rafale during Swiss evaluations, even though the Rafale beats the Typhoon in all other parameters convincingly.
It's because the Typhoon has more thrust in comparison.
But the Rafale already beats the Typhoon convincingly in all the parameters that are actually relevant to the IAF.
Note that this is the NWA Phase II evaluations. These evaluations considered the Rafale and Tyhoon as to what they will be in 2015 compared to Phase I which took into consideration the actual flight tests in 2008. And the Rafale achieved all the Phase II metrics in 2013 while the Typhoon may or may not achieve it even by 2020, like the famed Captor-E AESA radar. So the actual score for the Rafale is higher than what's shown while the Typhoon's is lower.
But hey, the Typhoon can run away pretty quickly due to the performance advantage.
The Typhoon is not 2t heavier than a Rafale. A Rafale B weighs 33,000lb with fuel and a C is 1,000lb lighter. Fuel weight is 10,300lbs, giving 21,700lbs empty weight. Typhoon is 11t (24,200lbs) empty with 11,000lbs of fuel. This calculates to a TWR of 1.15 for the Typhoon and 1.06 for the Rafale, although BAE quote 1.2+ for the Typhoon largely because the engine thrust rating is highly conservative.

This why the Typhoon got a 9 for performance and the Rafale a 7.

Rafale, TWR 1.06 @ fuel fraction 0.32. But actually EJ200s are underrated, which is why BAE state TWR as 1.2+.

The Rafale C all-up weight of 30,900lbs was a big lie, it was always 32,000lbs.

And engage very well too. It's called hit and run. And that was with the mechanically scanned radar too. With the AESA Kuwait and SA are getting, you can bump the engagement, detection and acquisition figures up to 9.But hey, the Typhoon can run away pretty quickly due to the performance advantage.
This is not F-16.net and TWR is not the be all and end all of aerojet performance. F-14A had 93kn×2 engines with a TWR of 0.56 yet achieved a top speed of Mach2+. Aero and engine characteristics play anequally important role. That's why Tejas despite having a slightly better engine than Gripen C with a lower empty weight still can't compete on performance.

BS. That retarded feature is only part of Kaveri, not F414. What that really means is that Kaveri performance is much lower than traditional engines during take off and climb and only comes up to match them when they have reached 10000ft.
For god's sake, use non after burner thrust, not the top thrust for calculating supercruise. Super cruise is without after burner
Do you have evidence that Tejas can't compete with Gripen C? Are you making up things or is there some source?
Top speed is top speed. You talk as though you drive you car or motorcycle only at top speed. Do you even know what top speed is?
You open up the throttle, then you will eventually reach top speed. That's worthless. What you need is acceleration, the amount of time you take to reach top speed.
And once you reach top speed, it's about how long you can maintain it and at what cost. The Mig-25s engines have to be thrown away after it reaches top speed once.
Also a 20-year experienced fighter pilot has probably only spent 1 or 2% of his life at speeds above mach 1.5, only a few minutes. Most combat happens at subsonic speeds. Supersonic speeds are only for one purpose, for transit, which nobody does at top speed.
Even the Su-30MKI, it uses afterburners to take off, once it reaches a high enough altitude, 100-200m, it shuts off the AB and climbs to either a few Kms or 9+Kms, then turns on AB to generate speed up to mach 1.4, then turns down AB to minimum and maintains a mach 1.3+ speed for the duration of the flight for transit. The AB is used because they want to quickly transition from subsonic speed to supersonic speed without bleeding fuel in the transonic region. So the F-22 and AMCA will better this speed by mach 0.3+ and maintain that for twice as long without AB instead of minimum AB.
Nobody flies at an aircraft's top speed unless they are actually testing something. So most pilots in fact don't even reach top speed in their entire life.
Complete trite. All engagements see the use of AB. Every aircraft tries to fly as fast and high as it can to impart the maximum energy possible - potential and kinetict , to the missile. That's why combat Radius in A2A segment includes some minutes of Afterburner usage. Also applies to dogfights.
The rest of the post; Please see -Complete trite
You are being utterly stupid. Using afterburner and top speed are two completely different things.
You can turn on afterburner and fly at subsonic speeds also.
No you are. F-14 was just to illustrate that TWR only paints an incomplete picture. Aero plays a massive role dealing with transonic drag and high altitude performance. You can only optimize your aircraft for a certain flight profile.
F14 had empty weight of 19.8tons, fuel of 7.2 tons and MToW of 33tons. The engines were twin TF30 having 65/112kN thrust each.
So, I want to know from where did you get TWR figure of 0.56?

As per wiki super cruise is possible in Gripen NG which uses F414 G and at a max speed of 1.2 Mach where as F22 can fly at 1.7 Mach with super cruise i.e without using after burner.This feature mainly impact fuel fraction,heat signature and efficiency of engine.Though f18 uses same engine can’t do super cruise may be due to naval based design.As AMCA is a stealth design fighter plane hope we will get super cruise >Mach 1.5 ... no doubt it would be a great achievement.

BLC suction is also a kind of BLC which is based on suction rather than blowing. But BLC blowing has more benefits as it increases the effective MAC of the wing.A great video explaining Supercruise in F16XL (Delta Wing LCA MK2
