tech demostrator or fully fledge prototype

What's the difference between a tech demonstrator and a prototype?

One is intended for production, and another isn't. The J-20 is intended for production, thus it is a prototype (however incomplete you think it is).

not necessarily, the Rafale A flew with F404 and was a tech demostrator, it was not until the Rafale C and M real prototypes emerged.

YF-22 flew with F-119 engines and TVC nozzles

Nominal semantics.

The point is the J-20 is a design intended for production.

The term tech demonstrator is only significantly different from prototype if it's meant to imply something different. Your usage of it doesn't seem to be the case, so this discussion is somewhat pointless.

i agree in that, but in its current form?

the EAP is basicly a Eurofighter and the YF-22 a F-22 too


how can you be certain the production aircraft might not change radically as the YF-22 changed into the F-22 or the EAP into the Eurofighter?

Re: J-20... The New Generation Fighter III

if this thread is only for news then i suggest all comments based upon no other thing than news being repress, otherwise i feel is really unjust some people here can say is not a tech demostrator while other are denied the oportunity to have their own opinion.

If we are going to play by rules everybody should play by the same rules.

You won't be repressed, but the mods will just move all posts to the other J-20 thread.

Everyone is playing by the same rules, but there are some... "facts" which are near universal.

Like if someone went to the J-10 thread and started writing about how the J-10 was just a Lavi with a different intake (but without quite trolling) people will not have much patience either. It's a similar case with the J-20 being a "technology demonstrator". Of course it would be out of line to put in the real rules "everyone must accept this and this as fact otherwise you will be banned," but there are some unwritten constants everyone should abide by.
If you choose not to, well no one's going to "repress" you but they sure as hell will not be leaving you unanswered.

I don't, but you don't know that it will. Either way that doesn't mean the design isn't intended for production. I wouldn't called the change from the YF-22 to the F-22 radical either. It was a refinement of the design. I expect that if there are any changes to the J-20, it will be the same case. Either way, I don't think that distinction will tell us much about when the design goes into production. Every country (and even every project) has a different pace and process.

tell me what news are these?

I find it ironic those who claim the J-20 is a tech demonstrator. What tech is there to demonstrate? I thought all of China's technology is someone elses in the first place already in production.

It is quit funny other can say their opinions freely and if i say something they said moves migs comments
by airsuperiority

Can someone move Mig's post to that other thread? He lost his way again. And seriously, he is NOT a news source, so I don't think he belongs here if he's gonna try and announce anything, especially regarding his wee personal opinion of the J-20 that no one really cares about. This thread is for people to follow the J-20, not his rants. Yea I'm also saying this thread is a haven away from his words.

Also anyone can see how Mig deliberately slides his way into bashing the J-20 in his post



These only proves one thing i have oppinions which are not shared by others while i do not share then i am an outcast.


if the thread is news it should be only news and pictures and commenst should be kept to a minimun

Otherwise it shows discriminatory application of the rules how come some can say it is not a tech demostrator and others do not?

If it is a News thread only news should be posted and coments kept to a minimun.

the rules sould then be kept fair for all

what i said is the J-20 has not cleared the prototypel stage and is hard to know if this is the real configuration or not, you might be right but also i might be right too, but without the right engines it is hard to tell it has fulfill its requierements

I don't think anyone has stated that the J-20 has cleared the prototype stage. It's only been test flying for half a year. I doubt anyone think it's fulfilled its requirements either.

yeah but i meant for example

The Rafale A was fitted with the F-404 but the later Rafale C and M used the french engine.

Similar could be the J-20, it might use its WS-? and later the intended engines, the Rafale A was a proof of concept.

The EAP was more different, it was powered by Tornado engines but most of it was a Eurofighter.

The YF-22 carried the core engine F-119 and most of the basic configuration, they were tech demostrator not research aircraft.

the X-29 was a research aircraft and same was the X-31 but the EAP was, i do not see why people think is offensive to say the J-20 is a tech demostrator that might be refined and change like the EAP turned into the Eurofighter.

Sigh, let me ask you this. Do you consider the Su-47 and Mig MFI to be technology demonstrators? Because when you say J-20 is a tech demonstrator those two aircraft, are what I compare it with in my mind.

At the end of the day we are going to say that a tech demonstrator is not meant for production while a prototype is. J-20 is meant for production. Bingo.
