80’s design, check better the F-35 or this
The Raptor is old, is a old design based on old technology and old tolerances
And as the Yf-22 zigzag panels decreased when they went to the F-22, and decreased again when they went to the F-35, they decreased on every new design
people can’t realize it because their raptor fetish, but such thing has happened, the F-22 and the J-20 are old engineering
The F-35 and the Pakfa are modern engineering
1. Zigzag panels are increased as YF-22 became F-22.
2. Number of bay doors may decrease due to better integrated design but parallel edge principle will never die…
3. Because that’s the basics of any radar stealth design, new six-gen toys included…
so… talk about old engineering, i don’t see any 1-3 gen fighters have zigzag doors do they??
Production F-22.

you sure? :diablo:
oh well, and what about YF-23A? X-32A/B? X-35A/B/C, these kinda prototypes of LO aircrafts?
There you go mate, very first prototype of YF-23 as you requested:cool:
About the shiny nozzle
From Wiki,
…shiny metal surfaces, which have low emissivities both in the visible wavelengths and in the far infrared. Such surfaces can be used to reduce heat transfer in both directions; an example of this is the multi-layer insulation used to insulate spacecraft.
and from lecture notes:diablo:
as the lecture notes goes on:
The emissivity for most paints is about 0.9 regardless of colour, in the infra-red region.
they deliberately made the polished shiny surface to reduce IR radiation then?
Do you realize I made that J-20 image by modifying Paralay’s drawing? It shows what the canards might look like if it had forward sweep on the trailing edge. I did not have the Rafael in mind when I drew that.
I find it hilarous you used my fake picture to prove the J-20 is influenced by another aircraft. I also notice you’ve posted this on another website as well. Maybe some day it will be traced back here where this silly rumour started. :diablo:
apparently people can say J-20 has the same layout as the Wright Brothers’ design as both aircraft have canard and all-moving rudder:diablo:
