We are thrilled about JF-17 static display, however.......
these pictures are good examples of some rusts you can notice (second picture clearly), I am a bit surprised that it is too early starting rusts/browns dry already on these parts. It must solved immediately.
In pic 1, what is that metal-bar pointing out, sideways, from the nose cone? Could that be some kind of tool to open the cone? It looks oddly positioned for it to be a sensor
In pic2, small gaps can be clearly seen between the canopy and frame..is that normal? Is the cockpit pressurized ? if yes, how is it possible?
I wonder if "smoke" is really a problem? The entire Russian line up of aircraft which includes Su-30/27 and Mig-29/35 series gives off smoke in certain conditions. I do not believe the smoke is let off during the entire flight, but at certain altitudes and certain conditions, it becomes more visible.
In close in combat this may be an issue, however most of the Russian engines in their past fighters like the Mig-21 had the same issues and they did alright in close in fights.
So it is what it is...the engine is solid, works well and the crews like the response times so I think its a minor issue.
Smoke is a problem, it increases observability both by naked eye and radar. In combat, it reduces the survivability factor of the fighter. Smoke is particularly worrisome because its presence indicates incomplete vaporization and combustion caused by unburned hydrocarbons (fuel). In layperson vernacular, it means low gas mileage - or wasted fuel.
Several studies including one conducted by MIT conclude that smoke is a result of poor atomization of fuel. An example of an atomization is the cologne some spray or atomize before a hot date.
Poor atomization(spraying) results in fuel size distributed droplets (some droplets are larger) and not optimally disbursed in the combustion chamber. Larger droplets cause incomplete combustion and smoke(pollution).
See below image of a fuel nozzle, an array of turning vanes deliver atomized fuel uniformly (size and distribution) to the combustion chamber improving engine performance.

What you see as a gap is quite normal and sits flush. The cockpit is obviously pressurized given the operational altitude of the aircraft.
How flush do you think this is? Although the cockpit is not shut all the way, but the finishing on the JF-17 is better in my opinion than on Tejas.
To your first question, its the AoA probe.
Theories aside, its a problem which Air Forces live and fight with. I have not seen RD-93 smoke in all of the flight profiles so this needs to be looked into some more. Pretty much the entire Russian line up is notorious for smoking, yet it has not had a major impact on the decisions of the buyers.
A couple of years ago, I spoke with an officer involved in the program and he said that one solution is switching the jet fuel type to reduce the smoke. Given that JF-17 still gives off as much smoke as initially, either that idea did not pan out or the PAF did not feel that it was as big of an issue.
in cold weather when most engines produce white exhaust for a minute or two after first starting. This is because the exhaust gas cools down when it runs through the pipes and muffler. The cool water droplets can freeze rapidly when they hit the outside air, producing a visible cloud of ice crystals. As the pipes heat up, so does the exhaust gas. It still ends up freezing, but over a wider zone because it takes longer for the water drops to cool down, and they're farther from the tailpipe.
