Why should it focused on bombing when this mission profile can be more easily shoved onto the CCAs, which are in their current form at an inherent disadvantage in air warfare. If anything it's reasonable to assume that direct strike gets sourced out towards low observable or expendable CCAs while the F-47 reserves long range air warfare for itself.
I’m not suggesting a focus on bombing. I speculating on a more broadly focused multirole fighter like the F-14 Tom/Bombcat. CCA’s will be little swiss-army knives; electronic warfare/jamming, fueling, strike etc. Those will add to the capabilities of whatever is deployed but, I’m sure they won’t rely on those factors for the NGAD’s entire design config.

I’m envisioning an F-47 that’s larger than the F-22. It’s unlikely adaptive-cycle engines will yield any advantages until CMC’s catchup and cut weight down. So range is still reliant on fuel. A larger airframe could carry more fuel, larger weapon compartments for more flexibility, including internal auxiliary fuel tanks.

The B-1B is phasing out and the Raider can’t replace it’s mission. Whether it may be penetrating strikes or heading out over the coast incepting a nosy navy. I think the F-47 may bridge that gap.
 
Commentators have expressed CCAs might be: isr, ew, bomb truck and finally forward decoy ie likely counter-air.. some one could update us.
Yes, and I'm one of them that's been pushing the CCA bomb truck idea.


So, given that the DOD wants penetrating counterair to be successful in a modern IADS environment, that points to heavy EW. I wonder how much of the EW load the NGAD will carry vs EW CCAs. That kind of warfare requires some powerful engines in a heavily networked anti-air environment like the SCS.
And a large airframe for the engine(s), fuel, and emitters.
 
I was expecting closer to F-15 maneuverability, but definitely not F-22 levels.
Given the currently known capabilities of the AIM-9x, is there anything that more maneuverability would even add? If they don't have separate sidewinder bays like the F-22 there might be an argument for more effective dogfighting capabilities in a full BVR loadout, but I don't believe the air force is going to think that's easier than just adding the dedicated sidewinder bays.

The problem is that Sidewinders are bulky, only 2ft/60cm shorter than an AMRAAM. Plus the earlier fins had the same span as AIM-120Cs. So overall you're better off making a self-defense bay AMRAAM sized and sticking a Sidewinder in it than making the bays specifically sized for Sidewinders.

At most some limited bay depth for 2 SiAW or AGM-88ERs at the expense of AAM space. It was designed to be the PCA element and whether its from the name or the descriptions, PCA seems very much air to air focused with little mention of any A2G work.
I’m sure they won’t rely on those factors for the NGAD’s entire design config.
This was one of the reasons for the NGAD review and program pause. There were reports before this that NGAD was designed to not require the support of CCAs (apparently per Kendall during an interview with Vago), but one of the major things that came up during the review was building NGAD with CCAs in mind.

Of the things that could actually be offloaded to CCAs at the expense of the manned platform, a certain degree of magazine depth / employment of certain weapons would make sense.

Additionally, I do not think any single type of aircraft can survive and remain inside a peer power's area denial network without CCA support on some level. Broadly speaking, in a system of systems fight, CCAs are the bare minimum it takes to not lose ground while PCA elements are the maneuvering element that can take advantage of temporary gaps to dismantle parts of the enemy system of systems.
It’s unlikely adaptive-cycle engines will yield any advantages until CMC’s catchup and cut weight down. So range is still reliant on fuel.
Im curious where this comes from. Im not knowledgeable in any part of aerospace, but reporting over the years do contradict what you said here.

Will it have more static thrust than F119s? Probably not significantly. 35k - 40k lb is probably likely.

But efficiency and fuel consumption wise, its been stated on numerous occasions that being able to transition between low and high bypass improves fuel consumption and efficiency. Conceptually it makes sense as well even if the high bypass isnt that much highwr
The B-1B is phasing out and the Raider can’t replace it’s mission.
That is true. It remains to be seen what the USAF plans to do for strike. It could be that they arent going to adhere too closely to the PCA definition and opt for a multirole F-47, though theres been no indication of that.

Penetrating strikes either in the form of direct bombing or standoff strikes doesnt necessarily require a manned fighter either.
Whether it may be penetrating strikes or heading out over the coast incepting a nosy navy. I think the F-47 may bridge that gap.
Throughout NGAD development, I really havent seen anything to indicate strike focus either as a primary or secondary role. Maybe some limited standoff missiles and SDBs at best. For the purpose of intercepting surface combatants, F/A-XX and the navy would be in much better position to handle that assuming F/A-XX isnt cancelled. It'll have greater availability and a fitting role for the job.

I read the article and didnt see anything about being set on the exhausts or not, but its also unclear to me how representative the rendered engine configuration will be for the actual exhaust section.

The render had been posted by PW before with the same paddle exhaust piping.

I dont know a whole lot about the engine but there doesnt seem to be an augmenter section depicted (unless its the section between the exhaust and the lattice casing section) and wouldnt such a nozzle reduce thrust from the engine? In the video you posted in the other thread, the overlay on the aircraft model also left no room for an augmenter, which is usually something like another 30 inches of engine length.

The lack of augmentor maybe just for testing - unless some magic is done such that the augmentor isnt needed. Not sure if demonstrator engines necessarily needs augmentors either. The flat exhausts plumbing would probably be good for observability, and it may reflect the shape of the production design, but I think i read elsewhere that the exhausts may also have variable geometry.

The exhaust nozzle is certainly just a placeholder and has absolutely no relation to an actual technical implementation.
 
It looks way more like this but, I suspect the final rendition will be airframe dependent. I would imagine 2D vector nozzles again, assuming it’s a tail-less design.

It’s just that - a rendering. Theres nothing from it to be gained.
There doesnt have to be anything gained. Its literally a forum for speculating and talking about secret projects and designs, many of which exist only on paper.

I fully understand renders are just renders and im not here to take them too seriously, however often times different renders produce a pattern that can be conremplated.

So....maybe I should be more clear. This kind of design had been depicted more than once elsewhere. I am simply curious of how thrust would be affected by such an exhaust shape and what options are there, if any, to mitigate thrust loss. These designs will also have similarly flattened internal cross sections even if they arent the smooth paddle in the render.

These just appear to be a more advanced asymmetrical convergent-divergent nozzle like on the YF-23/GE YF120 engines. I'm sure the thrust loss is minimal.

The bottom photo is a P&W YF119 configured for the YF-23. Not sure why it is strapped down to a pallet with old mattresses as cushions when there were specific shipping adapters to hold it on a 3000 trailer. The convergent section of the nozzle is symmetrical top and bottom, then the sliding lower tracked divergent aligning with the aft trough and independent upper divergent flap.
 
:confused:
Edit: This unofficial render is a screenshot, which was taken from the video by Pratt and Whitney.
See also: https://www.secretprojects.co.uk/th...ion-air-dominance-news-only.48613/post-881322
Source:
The model used by Pratt and Whitney is actually based on Rodrigo Avella's, using what appears to be VTOLicious's design from here, or one of his older models. It was also featured in the other XA103 video 7 months ago. A lot of people are claiming it is the F-47 design though. Edit: It has been modified though.

If we look at these images from the official P&W video, the plane also appears to have legs, but in this case, straight, not oblique.
I find it strange that a company like P&W doesn't hire a modeler to modify the model (my model in this case, haha) so that the engine outlets fit. Unless these exhaust outlets extending from the fuselage are a feature of the new NGAD.

It is difficult to imagine 2D from 3D.
Observations -
- superimposed XA engine doesn't match the CG jet aiframe
- YF-23 like diamond wing
- humped engine bays
- ventral tail strakes
- pitot's tube
- blade antenna behind cockpit
- anhedral wing
- horizontal or slightly dihedral canard
- 4x bigger heat exchanger exhaust dorsal grill b/w engines
- Animation mistake - for rolling right, the left flaperon, aeleron should move down, the right ones should move up.

So these features indicate a X-jet as it is said to be flying secretly since 5 years.
These days original photos & videos can be edited at will.
So either it could be an initial X-jet, a modified F-22 to keep it economical, or it is just CG by a quick edit of F-22.

So translating its view from roughly 45 degrees in azimuth b/w side & rear to 2D, it might look like this (2)

If I remember correctly, the exhaust duct on the X-47B behind the non-afterburning F100-220 was a manufacturing demonstration duct, showing how it could be formed and operate, while not having the full serpentine LO shape of a proposed production version.
 
I'm aware this is a render, but would we be thinking that the light colored stripe is a formation "slime light" or is it a large air nozzle for control-surface-free maneuvers?
 
This is literally a Franken-Raptor. It looks like they've swapped the tailplanes, attached them to align at the intakes. Then stretch the main wing end to end. Also removed the vert stabs. Note the wing similarities. Has the small aileron and the tip notch. The whole wing looks stretched on the X-axis.
 

It might have been just the thing to say but at the Warfare Symposium a USAF general said “we will soon fly the world’s ONLY 6th Generation fighter”
 
Whomever created that artwork. . .if the F-47 or F/A-XX actually looked like that (and performed, obviously) I'd be delighted.
I wonder why patiently discuss another marketing fluff aircraft (gosh, just look at that nose boom) from PW that apparently nothing more than [AI] art imagination just like [no less stupid] VTOL design from their recent ads?

A friend of mine emphasized that whats to come is the first true Sixth Generation Fighter in the world and is excited to see what the public thinks when they first see it.
