evo nekih cinjenica o t50 skupljenih od strane takozvanih insajdera....
This is T-50-1, it's leaked and someone's head's gonna roll (there was
another photo with bay doors opened, but it didn't spread)
* What we see is indeed the engine front: as I suspected, for the airframe testing it was decided to drop the engine shielding completely
* The configuration is nowhere close to the final, and will be changed, perhaps rather dramatically, including the shape of a duct
* The radar blocker will be installed into the intake, which is NOT the fan-like contraption we often see, but a 3D coaxial labyrinth
* The radar blocker is already designed and produced, but now is installed only on T-50-KNS, and is absent on the T-50-1
* The radar blocker significantly alters the airflow in the inlet duct and current engines on T-50-1 aren't optimized for it => power drop
* That's why it isn't installed on the airworthy prototype, which suggests that it still uses older 117S engines
lacko ::Citat: S-shaped channel is worse that the aircraft have to wear a lot of empty space, the larger the midship area and front projection. And with regard to non-zero ESR radar-blocker, Duc have s-shaped channel EPR also not zero. a radar blocker can make multi-mode. Let me explain: we take 2 rings, among them "blade" made of flexible RPM. If you need more traction, then leave the blade straight, if you want invisibility, that povrachivaem one ring relative to the other and the blades become s-shaped, twisting Everyone remembers a hint about the "interesting" lattice and "elegant solution"? And critics nonplanar Broch want to say that this does not increase the belly of the EPR in the frontal projection, zoto reduces midsection. EPR at such a layout increases only with irradiation from the side-bottom, and this is when the aircraft is already protetel over radar
malo sam cesljao jedan ruski forum pa prevede preko gtrans-a i ispade zanimljivo....
ok j ovo, donekle.
sta cemo ako zelimo stelt na velikoj brzini superkrstarenja? kaze da ako treba ostvariti veci potisak, onda teba ici na ravnu konfiguraciju. gde je onda stelt?
jos nesto-ja na onoj slici jasno vidim dva reda lopatica, a lopatice su jasno iza glavnog tocka stajnog trapa, sto bi znacilo da je to u stvari motor, jer nema prostora za blokator, koji bi treblao da ima odredjenu duzinu.
naravno, moguce je da blokator bude postavljen u kasnijoj fazi projekta, li to ujedno znaci i danije zavrsen njegov razvoj.
Superkrstarenje ili supersonican let pod forsazom, svejedno vazduh do motora mora dolaziti brzinom manjom od brzine zvuka.
Nije potpuno iskljuceno da je ono AL31 motor, da li neko ima sliku kompresora ovog motora ?
al31 21 lopatica u prvom redu, al41 23 lopatice. znaci u jednom kvadrantu 5,25 lopatica kod al31 ili 5,75 kod al41. na slici se vidi da je u 1 kvadrantu (vidljivom) priblizno 5 lopatica, odnosno, reklo bi se da je, ako je ovo motor, u pitanju al31.
Zasto slabo ?
Jasno je od pocetka da nije leteo sa novim motorima, vec nekom proverenom varijantom. A u vezi price oko polozaja motora, lica kompresora, radar blokatora, "S" zavoja uvodnika, zasto se uopste opterecivati time ?
Sve te tehnologije su ruski projektni biroi vec isprobali i napravili na raznim modelima i demonstratorima. Uopste nije pitanje da li znaju kako da naprave uvodnike stelt karakteristika, jer definitivno znaju. Vec koje ce resenje primeniti za PAK-FA, a u ovoj prototip fazi dok je jos uvek bez svojih motora, to sigirno necemo saznati...
