It is incredible that the raptor could turn around in about 10 seconds.

i think the video is speed up

Very likely different speeds, altitudes and weather etc.. very hard to visually compare most performance parameters.

In fact T-50 also engaged in afterburner. Russian engines generate blue flame when afterburner is on (instead of yellow flame like US engines), making it less visible.

Flame color is mostly a function of fuel type, flame temperature and oxygen mix, so may tell an engine expert a thing or two.

No Burn, same plane 1= burn,same plane 2= burn
Burn Su-47
Izdeliye 117 Burn

Do you see difference ?
Non burn = ring of flame
Burn = disk of flame

[gta4]

the flame color of afterburner relies heavily on fuel. Here are some blue ones

It is not in the color of the flame but in the degree of luminosity of it.

It's a airshow, even if the F-22 finished first he had literally no energy at the end of the turn, not how that pilot is prob trained to fight that aircraft IRL. All of the videos shown are airshow clips which really don't mean much, if all fighter aircraft were chosen based off air show performance we would have a lot of useless aircraft flying in the world today.

LOL, ain't it the truth ... Oh Yeah !!! Let's see the Russians keep up with armed Extra 300's https://www.youtube.com/watch?v=NYMzj3E_Xw0
(note: see SU-31 https://www.youtube.com/watch?v=eghdHbnERVo )

Well we know now what makes a great fighter ... Cobra that dude!

The color of the augmentor plume is mainly dependent on the temperature (read into this efficiency) of the flame. More heat = more power. Visibility of the flame is dependent on ambient conditions and background lighting. Photographs and videos can be highly misleading because most do not capture the true transparency, visible light, shock wave movement, or flame variance within these supersonic exhaust plumes.

If you look at photographs or videos of the F-16 with the F100-PW-220/220E engine versus the F100-PW-229/229EEP engine, you will notice a huge difference in flame color. This is not due to the fuel or it's additives; they're all burning JP8. (Even the +100 additive did not change the color of the augmentor plume) When you watch PW220, PW229, GE100 and/or GE129 powered Vipers taking off from a field at the same time, you can specifically call them out based on noise and color.

The PW229 series engine is hundreds of degrees hotter than the PW220 series. The PW229 has a lower BPR than the PW220, but has a higher exhaust gas velocity, better augmentor fuel system, wider range of staging, more advanced flame holder.

This difference is also very noticeable in the F-15E Strike Eagle fleet which uses both engine types. (Typically not in the same Wing)

An important thing to remember is that although the newer Russian engines have a 'bluer' flame (hotter) their engines only last a fraction of the life as their Western counterparts. While they may have more performance in the short-term, their maintenance cost will be magnitudes higher in the long term.

Anyone can 'turn it up' when it comes to jet engines; the trick is turning it up enough for the required performance without killing the engine. The key to longevity is turning it up with the proper technology to make a LASTING engine, that will not burn out after a few bursts of speed, or 12+ years of use.

PS - if you see a 'ring of flame' inside an engine nozzle, the engine is in augmentation/reheat/augmentor. If not THERE IS NO VISIBLE FLAME that will appear in the engine's exhaust.The exception seeing 'light' inside the nozzle is the F119 who's turbine CAN be seen during certain phases of operation due to the turbine blades glowing at their maximum operating temperature. (Other new engine types may do this as well, but it is a constant glow not a flickering fire.)
