It does not matter the 'who' but the contents and it does not matter what happens outside this forum. Going by your criteria, we should dismiss you completely because YOU have not produced anything while the likes of Lockheed, Boeing, Sukhoi, and Airbus produced much more. Inside this forum, you boasted and boasting will result in a challenge. I used your own words in your own claim. Now back up your claim.
Why is a 'round nose' less effective at RCS control than a 'non-round nose'? You are correct but that is from guessing in comparing 'looks'. You violated your own rule. To redeem yourself, you need to explain your guess.
I will play your game this one time.
I believe a round nose reflects radar in all directions at a relatively constant intensity. This means the radar reflection is detectable depending on the sensitivity and distance of the enemy radar.
However, the shaped nose is superior for stealth because if you examine the shape carefully, it redirects the incoming radar energy below the chine line into only a few directions.
An examination of the shaped nose above the chine line shows that it relies on the "continuous curvature" principle for stealth.
An examination of the shaped nose below the chine line shows that it mostly relies on the facet principle for stealth. Below the chine line, the nose is not completely faceted due to aerodynamic considerations. However, it is mostly faceted.
J-20 Mighty Dragon nose follows the "continuous curvature" principle above the chine/ridge line. Below the chine/ridge line, the nose follows the facet principle.
You mean you are busy scrambling to find an explanation to support your claim but so far have failed miserably.
No. If I play your little game then DrSomanth999 will demand that I reply to his thread. After that, every troll on this forum will keep challenging me. I do not want to go down this slippery slope.
If I agree to your bait, it sets a dangerous precedent. I'll have to keep replying to trolls indefinitely.
I still think replying to your little game is a bad idea, but I'm willing to try most things once.
