Just because the process is relatively simple to describe, doesn't mean it's simple to actually do this. There are decades of test and prototype data comtained in car computer models. And that's on top of decades of car development and building know how. And then there is the fact that the next car will be mostly the same.

 

This means that for stealth aircraft you need to have decades of tests and prototype data for these models to be as good as what the car industry has for cars. And even then the results of the models will only be valid as long as your next design is roughly similar to what your models are based on.

The US started with building and testing a lot of stealth prototypes around the 1970's, this means 3 to 4 decades of prototypes and tests. Not my definition of easy.

 

PS

One of my vague hunches is that the wing configuration of the reaper UAV (front wings straight tail wings V), might be an application of some data learned from developing the YF23 (front wings straight tail wings V).

> That is a direct derivative of the Delta 1



Yes, Daewoo took over the engineering responsibility of Delta platforms from Opel, and converted Delta 1 into Delta 2. It was Daewoo engineers that handled that conversion, and this is why you see first wave of Delta 2 vehicles are Daewoos, and this is why the first Volt demonstrator wore Daewoo grill.



> Exactly backwards. Who owns OPEL?  At least for now GM.



Opel engineers are Germans, not Americans, and Opel engineering takes place in Germany.



>  (That is actually Subaru and GM Canada that dopes the design for the chassis classes.)



I get a strong sense that you and I belong to different parallel universe. In our universe, Subaru is a subsidiary of Toyota and engineers Toyota AE86 remake and Toyota mini-cars. I don't know how things are like in your universe.



> GM designe all of its powertrains in the US.



Not in our universe.



> A lot of the Bodywork now comes out of ITALY.



Again, not in our universe. None of GM models are styled in Italy in our universe.



> Source data including commercial.



You may have failed to notice that that was the older previous-gen Lacetti in your youtube video, unrelated to the current one on sale since last year.



> Compact Power.LTD which developed the tech



Well, I see CPI's web site covered with LG logo all over. Furthermore, this is what CPI states <link... >








> Just like Thales claiming that their American software subsidiaries are French? 



But you said Opel tech was American because it was American owned.



> And that too is one of your lies. SUBARU ring a bell?



Yes, Subaru the subsidiary of Toyota Corporation. At least in our universe. I don't know how things are over there. Maybe the Soviets are still around and China is still dirt-eater instead of being USA's No. 1 creditor in your universe.

Seems to me that you just make up the lies as you go along. I really wonder about you.

The vender(KAI) mock up of KFX surfaced in one of its development road map.

 

 

So all this hullaballoo you spilled all this forum  is over an uprated T-50 with a reheat engine and a split tail? Just what kind of a fanboy are you?

 

We built something like those once. They were called F-5s. 

 

Sheesh.

1. T-50 already has an afterburner.

2. KFX is a twin engine aircraft, as the vendor mock-up makes it clear.

3. I don't see any external weapons store, do you? Guess where the weapons are stored.

And you expect to be taken seriously with a reply like that?

And ask someone sane why that is the only answer you deserve.

That's right, kid. I'll hurt your feelings by telling you the exact truth.
