Did the Backfires ever come out to play HeyJoe?
Certainly on my Bucket List but never saw them
Did the Backfires ever come out to play HeyJoe?
That is a very casual observation. In the world of supersonic fighters, if you mean that they are both swept wings with pointy noses and v-tails, then sure -- along with a lot of other planes. As a former windtunnel engineer, I would strongly argue the two are aerodynamically very dissimilar. There is a lot more going on here.Have you seen the J-20? Uncanny resemblance to the F-22
Point taken, but if you had everyone else's design specs, then you wouldn't require a tremendous amount of R&D to build from someone else's design, right? That's the point I was making is that while the PRC does spend some money on R&D, it's not nearly as much.That is a very casual observation.

The J-20 is a standard delta wing with a canard. This is extremely significant in terms of aerodynamics and center of gravity. Not only is it fairly tricky to design, but a canard directly reduces longitudinal (pitch) static stability. The F-22 is a clipped delta wing with lots of reverse sweep and a standard eleron. If you walked into a room of engineers and said "Let's build a fighter with a canard" they're all going to wince and say "Are you sure?" It's a lot more work. So why would they do it? Well, as it currently stands, the Chinese are still testing vectored thrust on the J-20 and the original design doesn't incorporate it. A fully movable canard adds boatloads of maneuverability in the same vein as vectored thrust. It's a design trade-off much like anything else.
That said, every design team does significant amounts of research on other planes in their category and plenty of aerodynamic concepts are rehashed from one manufacturer to another. They'd be doing themselves and their company/customer a disservice by designing in a vaccum -- it's their responsibility and the first step in the design process to do this research. If anything, I think we would be better served to take the J-10, Dassault Rafale, and Eurofighter Typhoon into account when discussing the J-20:
The J-20 takes a lot more cues from their J-10 and our French friends than it does the F-22. If we're having a look-a-like contest, the SU-57/T-50 wins hands down. And here's some canard porn from my former life...
Israelis were able to build Nesher/Kfir that way from purloined Daussalt Mirage V blueprints. In both cases, that’s a lot of NRE you don’t have to invest if you are merely tooling up to build to print!Point taken, but if you had everyone else's design specs, then you wouldn't require a tremendous amount of R&D to build from someone else's design, right?

I thought that they didn't do R&D....they just steal others R&D and go into production. Have you seen the J-20? Uncanny resemblance to the F-22...They certainly spend a lot less than the US.
With a GE J-79 for us to still have muscle in the game.Israelis were able to build Nesher/Kfir that way from purloined Daussalt Mirage V blueprints. In both cases, that’s a lot of NRE you don’t have to invest if you are merely tooling up to build to print!

Funny you should say that as George hired the same designer who did Sled Driver to lay out our book. I think our book was a bit more affordable!
Just checking out the lumps and bumps from below.
We easily left the tattletales in our wake
