Engine smoke is still an issue. Sherdils fly the T-37 Tweety birds.
Sir! thankyou for clearing up the model. If you happened to see this parade and the one last year, as compared to the previous year the smoke was very much more. Whereas if we go by the theory it should had been less because according to the offical claims, smoke issue was resolved to some extent, why was the smoke more as compared to last year when we got the first 2 prototypes for a flypast on 23rd march?
I really have a bad feeling about this.
so does anyone know a bit about this
"Although the 60% of the airframe will be manufactured in pakistan, does this mean that we will produce the parts through our own metallurgical experience or will we just ship those parts from china and assemble it?
I don't take assembling an aircraft to be the same as producing one. What can this mean for pakistan's defense industry? I know that PAC has its own wind tunnel, will we be able to design and produce our own aircraft in the future if necessary? Can someone please answer these questions, I don't want my patriotism getting in the way of facts."
Hon Batman, gas turbines donot necessarily use natural gas as fuel. Gas turbine merely refers to the fact the hot gases are used to derive the turbine blades, where as steam turbines use steam and wind turbines use power from the wind.
Nearly all the refineries that I have worked, used gas turbines to generate power. The last one used fuel oil ( Furnace Oil in Pakistan) as gas turbine fuel. The fuel is injected into a combustion chamber and the resulting hot gases push thru turbine blades, thereby runing the supercharger for the air used in the combustion chamber as well as turning the alternator.
I also had the opportunity of visiting the Rolls Royce plant in East Kilbirde near Glasgow during my brief tenure at the National Engineering Laboratories and have seen the aircraft engines being assembled.
Early jet engines were pure jets but now nearly all the aircraft engines use some kind of gas turbines. Even the turbo props use turbines. While no expert on aircraft engines, it is safe to say that unless it is described as a ramjet or pure jet; an aircraft engine would be a sophisticated gas turbine. Thus RD-93 is a gas turbine using Jet A-1 ( a purified kerosene) as fuel.
Regret to sound like a lecturer, but I have the bad habit of not accepting an incorrect statement.
I think PAF is aiming WS-12 or EJ200 standard.
conformal fuel tanks perhaps!
no I am sure its not CFT, and I am not an engg so my guess by looking at it I see a white Antena. Or the Chinese just decided to change the design a little bit to see how the forces react with a flat top. Drag ( less or more ).
