That’s not really an exception though; I can’t think of any new Chinese engine that was not test flown in relative secrecy. There is also a well established pattern that more important military projects tend to be more restricted in terms of the pictures and information released to the public.
[USER=”31611″]Blitzo[/USER] – True. The Chinese are far more secretive than anyone else. But they did allow their stealth fighter prototypes to be filmed and photographed while in their flight test phase. I don’t see any reason why they would then hold back on the engine for that stealth fighter.
If China ever wants to be more than a relatively minor player on the world’s aerospace and arms markets then they are going to have to embrace some openness.
14 sailors killed due to fire on Russian submersible. May they RIP.
If the initial reports are right and it was the Losharik, then it means one of their bottom dwellers (the ones who investigate ocean floor data cables and sonar arrays) might be inop for a while and that half of its compliment died.
[USER=”77107″]J-20[/USER] – BOTH the Ws-15 and XF9 are in bench testing at the very least. Rumors and such suggest the Ws-15 has been in such testing since at least 2015 and the Japanese, I think, started their testing last year. The Chinese engine has been undergoing testing on the bench longer, but the Japanese industry is more integrated with the major manufacturers and so can probably go through testing in a shorter amount of time. Thus the question I asked.
[USER=”20787″]QuantumFX[/USER] – If they are flying it in secret it says a lot…they still don’t fully trust it yet.
Big missiles. Moscow is saying their follow on to the A-135 ABM system is to be ready by 2022.

It looks like Antonov has got just enough of a contract to not go full corpse.

[USER=”76365″]RALL[/USER] – Yes, the FGFA – as the program was defined – is almost certainly dead. But the biggest reason why that is so is because the Indians scoped it as a two seater. They did this because, historically, they’ve had success with it. But past success really isn’t a good reason to keep doing something. I mean, armies have historically had great success with chariots too…but you would never use them on a battlefield now.
If you look at the information technology aspect of where all the 5th and 6th gen programs are going, it is all about sensor fusion, pilot assistance, battlespace management and networking – and expanding this on to UAV helpers. The goal is to use the greater processing power to assist the pilot as the weapons officer would have in the past. The goal is to put less people in the line of fire and to give the pilot the ability to have the necessary (and sorted, prioritized) information necessary so that when he does goes in the line of fire he can do so with minimal risk. Having a second man in the cockpit is both retro and useless.
Give the Indian military a while longer to watch the other programs while working with the Rafale and they will head down the same path. The Russians likely knew the two seater concept was a mistake from the start. I mean, they never really tried to woo the Indian military by flying a two seater.
But in the near future, India has to do one of two things – go with a Su-57 variant (a single seater) or solidly lock in a partnership deal to develop AMCA fast. It’s not going to take China more than a few years to solve its engine woes well enough to fight test and field Ws-15. If they do neither, they will lose a lot of power projection capability in SE Asia.
They don’t conceal the engine nozzles or exhaust plume anywhere near as much as our stealth designs do. Rear aspect stealth will be heavily dependent on how well they can stealth up their engine. But they do have plenty of time to work on it considering the service dates that they are forecasting.
Speaking of XF9, which do you think we will see flying in the air first – it or Ws-15?

Still conductivity difference between aircraft frame and canopy glass. Still a surface discontinuity which will cause a large amount of diffraction and surface wave reflection… Right back towards the emitter
.
No, ActionJackson. Because, as they have stated, they applied layers of ITO to the glass. And they can tailor the conductivity of that through the thickness and number of layers, as well as the ratio of indium oxide to tin oxide (there is no molecule ITO). Similarly, the conductivity of the carbon fiber shell and the exterior coatings can be tailored by doped conductive particle size and number.
So do you have any actual evidence that they didn’t do any of this? Because I know this is not something you can see. In fact, I would bet you had never thought about it.
Interesting that even the Turks have recognised the benefit of having the canopy leading edge coming to a point and not having exposed frame in the aircraft’s front aspect.
That’s cause they went with a clamshell. With the Su-57 though the front part is a fixed piece. And so there is no gap there and you can design a continuous conduction path. Irrelevant criticism.
You know, a lot of stealth is circuit analysis. I have some doubts about your eyeball’s ability to perceive that. 🙂
A DSI just won’t produce good airflow past Mach 1.9-2.0. So it isn’t going to be possible to go much beyond that because you are working your engines harder than you would have if you had used a diverter.
The project is brand new, and so I don’t know why they opted for the sleekness. (Maybe they thought it looked cool – I do.) A guess would be that they want a high supercruise together with stealth (a DSI is more complimentary to stealth than a diverter). Maybe it’s a design to supercruise at Mach 1.8 and it redlines at Mach 2.1. You get great stealth, a high and fuel efficient supercruise, and although the afterburners don’t give you much you won’t use them much anyways. It’s all speculation though until we hear what performance targets they are shooting for.
[USER=”8037″]Wanderlei[/USER] – It’s got a DSI. So it’s not likely to go much higher than Mach 2. That said, the point of a stealth aircraft is stealth. You won’t be going faster than that anyways because heating becomes too much of a concern.
The timeline is much tighter on FCAS (demonstrator by 2025? airframe possible, doubt engine will be ready, systems?). Meanwhile, the Tempest program needs to solidify partnerships. While I don’t see the two programs merging (Dassault will see to that), collaboration on propulsion would increase the odds both programs survive.
I wouldn’t go on to say that the timeline is much tighter. Everything I hear suggests they are about the same – post 2035. A demonstrator just validates proof of concept. Like with Japan’s Shinshin, it will run with a lot of existing equipment – engines, systems, etc. Like you though, I am skeptical that both European programs will make it to market.
Engine dev could delay the project considerably considering the timeline.
You bet. MTU is essentially just a contractor, and even Safran hasn’t ‘run the show’ with engine development in a long while. They got their work cut out for them in both technology development and program management. If it wasn’t for the fact that the Tempest is lacking partners I would be picking it to be the next gen European fighter just because I have a lot more faith in Rolls Royce. As it is…we’ll see.
European stealth fighter program to start with a demonstrator (so like Japan?).
“Airbus Defence & Space and Dassault promised that this would ‘initiate demonstrator programmes for launch at the Paris air show’.”
European sales impact of eliminating Turkey from F-35 program. (Of course, this only takes into account what is presently on the books. The lifetime footprint would be a lot lower.)
