PAF JF-17 in Farnborough Air Show 2010

[dbc]

Looks like this smoke is normal thing ...or maybe the use of low quality Jet fuel provided by the farnborough Administration to them...

..all engines smoke when throttle is pushed forward to MIL, it rapidly increases the amount of fuel sent to the combustion chamber. The engine is initial not ready for the increased fuel causing partially consumed hydrocarbons and consequently smoke. This lasts a few seconds until the compressor is able to provide more oxygen and the core temperature is increased to cope with the additional fuel.

The below video shows an F-16 engine smoke when throttle is increased. But all things considered the RD-93 does smoke too much...

Exactly, all engines emit smoke.

I do think PAF has made efforts to resolve the issue as we have seen reduced/no smoke in recent videos; just as in the video we see the first JF-17 with not too much smoke the other with a little bit more. Nevertheless, I do agree RD-93 does emit considerable amount of smoke as do all Russian engines.

The second pilot appeared to have pushed the throttle wide open perhaps he wanted to get home ASAP.

lol, quite a possible scenario. However, a more logical/interesting analysis I found online:

The smoke comes from the engine when it is at or near MIL power. (Which is top shaft speed/power the engine can run.)

The engine is trying to accelerate at the fastest possible rate. To accelerate a turbine engine you add fuel. When the burner kicks in, the smoke goes away as the flame of the augmentor cleans up the exhaust of the engine. (The smoke still enters the augmentor duct, but it burns off before it can emerge.)

When you cancel 'burner, the smoke will return as it is still pouring from the engine at MIL. When the throttle is pulled back towards mid-range the smoke does subside as the engine isn't trying to make so much power.

I've really enjoyed this thread a lot over the past few weeks. Some terrific photography and very interesting information has been shared. Thanks to all the contributors, your efforts are much appreciated. Keep up the good work.

but were you was its important qes for me sir jee?.

My PAF Techinician friend yahoo has been vindicated. Try to read the paragraph above the photo showing all the weapons, describing the Integrated Avionics System, somewhere towards the bottom it says,

"Secure communication and datalink system, enabling real-time target sorting and engagement:"

The explanation/expansion/simplification of this is "sharing radar data to prioritise and to shoot targets"!

guys i asked for these booklets but no one posted please some one post them in good quality.

Before anyone creates a new thread on JFT is a third gen fighter, let me clarify that this is a Chinese brochure and Chinese third gen= western fourth gen.

Good news guys, as per my info Azerbaijan has placed an order of 24 JFTs. Zimbabwe have already placed order in 2005 and they are just waiting for delivery. Egypt is most likely next customer as they like the aircraft and final negotiations on license setup are going on.

The guy at website you showed us is trying to get better quality images. I am on the look-out for the too.

Nabil can you confirm STOL Capability of JFT ?

Nabil can you confirm STOL Capability of JFT ?

Why would PAF need STOL capability?
