JF-17 vs Tejas at Dubai Airshow

[ozranger]

Tejas

JF-17

What are the aerodynamical differences you can notice between their demo flights?

 

[Windjammer]

Even before the wheels are retracted, the JF-17 can virtually go ballistic.

@waz @LeGenD please close this thread it will bring only flame bait and trolling thanks

JF17 foran khara hojata hai, Tejas needs a lot of viagra.

What is the turn rate comparison?

What is the turn rate comparison?

In sustain turn rate jf17 is better but in intentenaous turn rate Tejas is better

@Windjammer Whenever I read your comments, you remind me of the Munir (May Allah forgive his soul) from Pakdef. He was also very enthusiastic about JF17.

Tejas grounded after single sortie

Tejas grounded after single sortie

Very sad news. Another day, another aircraft grounded.

TBH , Tejas looks like hangar queen demo aircraft that only looks good on airshows


while PAF JF17 looks like a workhorse that highly experienced in combat against real enemy (not simulated)

after all PAF JF17 shot down IAF mig 21 and SU30MKI and drove away IAF mirage 2000

which prove the PAF training quality is far higher than IAF training quality , even though IAF have higher number of pilots/jets

The reserve unit of the Indian LCA Tejas, scheduled to fly today at the Dubai Air Show 2023, once again was forced to make an emergency landing shortly after take-off due to failure of onboard electronic systems.

tejas trust to weigh ration is apparently better. JFT looks a bit under powered

 

[CriticalThought]

In the Tejas video in OP, the opening sequence gives away the poor inlet design of Tejas. This means it is unable to go into high Angle of Attack maneuvers when starting from slow speed.

Imagine first the aircraft moving at high speed. The very speed of the aircraft ensures abundant airflow. As the pilot pulls up into a high AoA maneuver, the airflow continues to provide the engine with enough thrust.

Now imagine the aircraft flying at low speed, then the pilot suddenly pulls up into high AoA and trys to increase thrust. Due to poor inlet geometry, the suction created by the engine blades cannot draw enough air into the inlet. The engine struggles, you can hear the high pitch in the video, and the aircraft seems to be flying through treacle as it fails to attain height or gain speed, until the pilot pulls back and allows the aircraft to go into a controlled stall from which he then recovers.

This shows both poor pilot training, but also poor design for dog fighting. If the pilot needs to worry about his horizontal speed when deciding to go into high AoA, he is out of the fight already.

Make no mistakes, the rules of aerodynamics apply to all aircraft. But good aircraft like the JF-17 Thunder manage the airflow in a wider range of speeds than the poorly designed Tejas. It is probably the reason why we don’t see Tejas performing a meaningful high alpha pass followed by muscle climb.

Jf17 is far better than Tejas delta wings built only for speed at high altitudes like Sr-71/f106 whereas cropped tail delta wings like f15/f16 are built on agility/maneuverability

This is why the JF-17 needs the WS-19 engine once it’s available, a 42-44% increase in thrust will let the plane perform to the full possibility of its flight envelope. The JF-17 won’t be underpowered then. It will have nearly the same amount of thrust as the PAF’s F-16s!

The JF-17 with its current engine is akin for the F-16/79 (both planes have similar empty weight and similar thrust), but with the WS-19 it will make the JF-17 equal on many levels with a standard F-16.

As of this year, it is accepted that the WS-19 engine is ready but it will be time until it goes into mass production. After meeting the demand for the J-35 project, sparing a few engines to develop a JF-17 model with this engine will take some time. So perhaps we will see a JF-17D by the end of the decade. If the plane needs to be redesigned to fit the engine, perhaps the plane will get more enhancements to maximize the use of the new engine; especially in EW but also in being able to do heavier strike role as well as ability to supercruise in the way the Gripen can supercruise with its F414 engine.

China's WS-10 and WS-15 turbofan engines are now in serial production following the finalization of material verifications.

Any indication how the JF-17 compares to the following specs from the F-16/79?:
