- fighter - Can doppler radar be used to detect stealth aircraft by . . .
Both stealth and non-stealth aircraft can be detected or avoid detection, and stealth acts like setting your opponent's radar back by 20 years But it's not set back by 100 years Successful covert missions are much more achievable with a stealth aircraft, but still require planning and avoidance
- What is in stealth paint to absorb radar, and how does it work?
What is in the 'stealth paint' that coats stealth bombers e g B-2 spirit, and stealth aircraft, e g SR-71, and how does it absorb deflect radar?
- Do stealth airplanes need to limit contrail generation?
Stealth aircraft include options to reduce visual signatures, so yes This is achieved as a side effect of reducing the infra red signature, which is done by mixing the engine exhaust with environmental air before it is ejected, cooling the air a lot and thus making contrail generation far less likely
- Is the F-117 actually inferior in its RCS than the F-22 and B-2?
The only other stealth aircraft with RCS without RAM in the -3 to -16 dB range is the Su-57, modeled here, which is consistent with the manufacturer's patent And it's a sure bet that Lockheed's 3rd and 4th attempts at stealth are better at it than Sukhoi's first, especially being more of a "Silent Flanker" than a pure stealth design
- If stealth aircraft are invisible to radar, then how do friendlies . . .
If a stealth aircraft like the F-22 Raptor is almost invisible as said, it has cross section of very small metal ball Then, how do friendlies see their own aircraft in the air? Perhaps GPS datalink? As often said, stealth aircraft are not invisible to radar, merely harder to detect
- Why do many stealth aircraft have a similar shape and design?
0 Briefly, the design of stealth aircraft aims to reflect the minimum possible amount of radar energy back towards the radar This is achieved in two ways; firstly, the aircraft's shape is designed to reflect the radar energy, which is electromagnetic radiation, away from the radar This is what gives stealth aircraft their distinctive "look"
- Do stealth plane need to turn off its radar to remain in stealth?
If yes, the radar needs to be off, how can it detect enemy plane, locked-one and fire missles? If stealth plane still operates its radar, can enemy planes detect its radar emission and pinpoint it
- wing - What trade-offs are being made in the design of the planform . . .
Stealth technology uses angles in the aircraft shape, and homogeneous orientation of the surfaces In the F-22A Raptor wing leading edges, tail surfaces, air intake bypass doors, refueling aperture
