Poll - What inlet design would you like to see on the NGFA ?

[CriticalThought]

That would mean additional mechanics and sort of takes away from the idea of simplicity that came with a DSI. Well, nothing is for free so always compromises on something to gain another.

According to what I have read, the actuators for active flow control have no moving parts.

 

[Indos]

But the problem is, barely anyone here is competent enough to discuss and argue this topic simply due to a lack of understanding, even more without any information on the NGFA's requirements such a discussion even by the better informed members makes only little sense and will end up either in a plain useless poll based on pure aesthetics or personnel favour and in the worst case scenario in the possibility to mock and ridicule certain member's decision again since barely anyone here is competent enough to discuss and argue this topic.

Just my two cents.

Inlet design needs a Phd educated with broad experience, KF 21/IFX inlet design chief designer is from Indonesia though, not from Indonesian Aerospace, but ITB (Bandung Institute of Technology).

Many of the NGFA features will already have matured by the time its on the tarmac. Take note.

I had dynamic DSI in mind, but didn't know if the technology has matured enough because this is a 6th gen concept. If we can have it, then I am all for it.

Broadly correct. Under active development.

Think dynamic DSI with active flow control to control boundary layer before it enters the engine. Active flow control has been used to eliminate control surfaces. It would be a novel application to try and use it for removing the deficiencies of DSI. Maybe, you don't need DDSI to affect a wide range of morphing if you supplant with active flow control? @messiach

If PAF going for a clean design and not J-31/35 approach, so far the only hint of Azm fighter we have on video is a 3D model analysis similar to the F-23 design. Combining the elevator and stabilizer is a approach also used on Russian Checkmate for reducing material cost and for added low observability.

If the F-23 had been built with today know how, here is a representation of what the production model would have looked like.

Intakes on this jet have DSI and jagged edges. Hybrid of J-10C and F-23 intake. Rear end on production F-23 was supposed to be narrower because original intakes were designed for future reverse thrust capability which was later not a requirement.

Since Azm is supposed to be a strike fighter as well the F-23 design gives additional IR suppression on exhaust.

This Is What A Northrop F-23A Would've Looked Like If It Had Beaten Lockheed's F-22

Many argue that the YF-23 should have been selected over the YF-22 and these exclusive renderings show what a production F-23 would have looked like.

If I am not wrong, this is about testing such features onto Block-III and onwards.

@ All
What inlet design would you like to see on the NGFA ?

That is a moot question,
unless the flight characteristics and mission requirements are specified.

 

[messiach]

This is estimated guess. I have given it elsewhere.

Length 18.3 m, Wingspan 12.0 m, height 4.4 m, wingarea 70.7 m2, gross weight 24,500 kg approx, max takeoff 38000 kg,fuel 10000 kg, power plant 144 kN x 2 (afterburner), max base speed number 2.5 M with cruise speed 2000 kmp, range 5790 km approx, combat radius half of range with ceiling at 65000 ft, G limits +9/-4, rate of climb 370 m/s, wing loading 70 lb/ft2, estimated T/W 0.95 (fully loaded with 70% fuel)

@ everyone
So we have the the data...to begin with the subject.

The most efficient design to that equation would be probably same as Grippen.
DSI puts a restriction on plane speed; which is almost at the cusp of what was provided to me.

Bhai plz tell us which engine gives 144kN thrust.some wild guess.

I had the same thought too right that moment she posted it ... concerning a Chinese engine, only a WS-10 derivate would fit (unless it is not a new design)

Thanks a lot, that's something to start with and exactly what I requested in my first comment in this thread.

Bhai Jan, there isn't one but there can be similar to Chinese engine. At-least start with data to configure an inlet and worry not about engine alone. You have engine details to help you out for inlet. Ab sab bata dain.

144 kn
there aren’t many options available in the world in that class for us

even f100-229 we use in f16 is 129kn
i can think of ws10 that isn’t much powerful either
or maybe u can shed some light

My guess is that the data provided here is proportionately adjusted to get feedback and it does not point to something that exist or built in its current form
