JF-17 Thunder / FC-1 Xiaolong

[Abdus Salem killed]

If the ejection seat was chinese then PAF pilots would be strawberry jam in ground

Is this crash revealed by ISPR yet ?

 

[kamaal]

Pak official sources still not claiming that it was a Jf. This should be 4th publicly accepted crash for Jf. I wonder if rd-33 is crashing this much, then what about those j-11 and j-10s flying with the Chinese indigenous engines. Thank God, martin baker seats were state of the art and performed its duty well.

Lol, 5th gen marketing for Martin Baker by PAF, now Martin Baker can say filed tested by PAF,

2 successful ejaculation simultaneously...

JF17 is a liability with faulty engine. Chinese claims about this aircraft specs are not true .

 

[Srinivas_K]

JF17 has become a liability for PAF.

In addition to engine and structural issues. The performance is diminishing and maintenance is costly for this 3.5 generation aircraft.

In fact, the performance of RD33 is better than that of F404. The red is the thrust curve of F404, and the black is the thrust curve of RD33. The high-altitude performance of РD33 is outstanding. Compared with F404, the high-altitude thrust is obviously better than the latter.
It can be seen from the above figure that at a height of 11,000 meters and a speed of Mach of 1.6, the afterburner thrust of РD33 exceeds 60 kN, which is equivalent to the afterburner thrust of F404 at a height of 6000 meters and at the same speed. It can be clearly seen from the figure that the lower the height, the greater the thrust. The F404's afterburner thrust at an altitude of 35,000 feet (about 10,500 meters) at the same speed is only slightly higher than 50 kN. It shows that the high-altitude and high-speed performance of the RD33 is quite powerful

1) RD33 max usuage is 3000 hours with heavy maintenance
2) Black smoke emissions coming from engine is a dead give away during WVR fights.

F404 is a reliable, low maintenance and gives consistence performance.

I am not sure about the graph you posted, I do not see any authorized analysis from a reputed source.

I feel this graph should not be taken seriously.

Can you tell me why they are going after J10 fighters ignoring JF17's?

There are question marks on J10 fighter performances also.

Do you know how black smoke is produced? RD33 uses a centrifugal nozzle. The engine is in a fuel-rich combustion state during low-altitude flight. At this time, the fuel supply is sufficient and the atomization quality is good, most of which are small-diameter oil droplets. However, the small oil droplets have low momentum and are concentrated in the recirculation zone near the nozzle. Thermal cracking and decomposition occurs in the high-temperature and oxygen-deficient recirculation zone. A large number of carbon atoms gather near the nozzle to form carbon deposits on the nozzle and head and make the exhaust smoke concentration.. The combustion efficiency at this time is not low,

The design of РD33 is not lagging behind. Like the F404, it adopts the unit structure design idea that facilitates the implementation of condition-based maintenance. It is divided into 11 units to simplify the engine structure. In terms of material selection, РД33 mostly uses titanium alloy materials. All parts whose working temperature is lower than 610°C are made of titanium alloy, while F404 uses titanium alloy parts whose temperature is not higher than 450°C.
РD33 is more willing to use advanced materials in the hot end parts. For example, the third stage of the high-pressure compressor and the high- and low-pressure turbine discs and the high-pressure rotor drum shaft are all made of powder metallurgy materials, but F404 is not used. РD33's high-pressure turbine blades are made of single crystal material, while F404 uses polycrystalline material Rene80. Therefore, don't wishfully think that the Soviet design is simple and crude. Russia is actually very willing to invest in key parts.

When you choose an aircraft, you can’t just consider the performance of the aircraft. Although JF17 has excellent low-altitude subsonic performance, it has poor climb performance. When a war with India breaks out, India will organize su30 raids to the rear of Pakistan. At this time, a supersonic performance Excellent aircraft J10 is needed.

JF17 as per the design requirements, is basically designed as an interceptor. Seems the design has not met the specifications.

 

[Marliii]

Pakis were mocking russian engines of IAF fighters without realising that their junkfighter too has a russian engine

If the JF17 is designed as an interceptor, it will not use a large side wing similar to the F18. It is only to protect the Pakistani ground forces. In fact, LCA pays more attention to interception performance.

The initial requirement was to replace F16 but they wanted to tweak the design to accommodate low speed performance as well.

No, at first it was the J7 upgrade plan, also called the Super Seven Plan. Pakistan provided funding, the United States provided the engine, and China and the United States jointly designed it. However, after the Cold War, the United States Grumman withdrew from the plan, and then Pakistan also terminated the plan. China did not want to To let this nearly completed aircraft abolish, China decided to develop its own independent development. When the Singapore Air Show, China showed its research results to Pakistan. At this time, Russia was willing to provide engines, the project restarted, and Pakistan wanted to purchase Italian radars, but the project would be postponed. After that, China showed the Chinese radar to Pakistan, which has the same performance as the European radar, which did not delay the project.
If it weren’t for China, no airline would provide JF17 at such a low price. JF17 would not be completed at all. Pakistan’s China-Pakistan joint development is wrong. Pakistani pilots have basically no influence on the development of JF17.
