This is where you are making the mistake, Also if don`t know shop ranting and trolling hopelessly..
I don`t have to look back what i said, I stand what i said, You cannot GOOGLE for my qestion because it something very basic..
Either you replay straight what i asked in #137, Or don`t reply or you can ask, Any more of this BS will be reported next time..
Are you HIGH? You said:
"Btw, Do you know what is technology demonstration ?, Yes the present J-20 is a technology demonstration so does was T-50-1.."
And when I corrected your error, you said:
"Define, What is technology demonstration in technical terms not some one copy paste ?
How technology demonstration are related to Prototypes ?
Technology demonstration and Prototypes are both related to experiment..
Find out what are these and the relation and then you may post, Post quality not rubbish
Indeed i know better than this.."
I gave you a definition for BOTH of them, TWICE already, I even gave you examples. You just don't want to admit that you were wrong to call the T50 and J20 tech demonstrators. Again
google the definition of a technology demonstrator:
"A rough example or an otherwise incomplete version of a product, put together with the primary purpose of showcasing the idea, performance, method or the features of the product. They can be used as demonstrations to the
investors, partners, journalists or even to potential customers in order to convince them of the viability of the chosen approach." They aren't meant to enter serrvice, eg:
Su 47 Berkut
T50: "The Sukhoi
T-50 is the
prototype for PAK FA" That's from Wiki
J20: The
Chengdu J-20 (
Jian-20;
simplified Chinese:
æ¼-
二å;
traditional Chinese:
殲-二å;
pinyin:
JiÄn èr shÃ) is a purported[SUP]
[5][/SUP]
fifth-generation,
stealth,
twin-engine fighter aircraft prototype developed by
Chengdu Aircraft Industry Group for the Chinese
People's Liberation Army Air Force (PLAAF)" Again from Wiki.
The T50 and J20 are PROTOTYPES, not technology demonstrators, PERIOD. Stop running around in circles, calling people trolls because you don't know the difference between the two. Good day.
