Ovo nije toliko bitno, nego koliko se daje pregled stanja ostalih vazuhoplovstva koka muku muce sa zanavljanjem dotrajale tehnike.

Missing F-35s Replaced By F-15 Refurbs
May 28, 2009: The U.S. Air Force is developing a refurbishment program for its F-15 fighters, most of which are over 20 years old, so they can extend their useful life from 8,000 flight hours, to 12,000 hours. The U.S. Air Force wants to extend the life of some F-15s because of delays in getting the new F-35 into production. The F-16C, which was originally designed for a service life of 4,000 hours in the air, took advantage of advances in engineering, materials and maintenance techniques have already extended that to over 8,000 hours.
Aging combat aircraft are a worldwide problem. Earlier this year, the Chinese Air Force began retiring its first Su-27 fighters, or at least the airframes. These aircraft were bought in the early 1990s, and 24 of them have reached their service life of 5,000 flight hours. "Service life" is a limitation all aircraft have, although it can often be extended. In addition to the F-16 and F-15 extension programs, the U.S. A-10 also had its service life extended from 8,000 to 28,000 hours. Same deal with the B-52, which had its useful life more than doubled, via several refurbishments, to 28,000 hours. Engines, electronics and other components have different service lives. So the retired Chinese Su-27s were stripped of most components, for reuse as spare parts.

Russian warplanes have, historically, had short service lives. This includes all components, especially engines. The MiG-29 was designed to last only 2,500 hours in the air. A refurbishment program has since been developed to extend that to 4,000 hours. The MiG-29 was a watershed design for the Russians in the 1970s, who were beginning to build more sturdy aircraft on the Western model. Thus the Su-27s, which were designed a few years after the MiG-29, had the longer, for Russian aircraft, service life of 5,000 hours. Before that, most Russian aircraft were only good for 2-3,000 flight hours.

The Chinese Su-27s, which normally have two pilots assigned (a common practice worldwide) apparently allowed each pilot to get 120-130 hours a year in the air. That's less than Western pilots get, but twice what pilots used to get in communist countries. That's because these nations had Russian aircraft that would be quickly worn out if you allowed the pilots to fly them as much as their Western counterparts. But the Russians saw the error of their ways before the end of the Cold War, but not in time to re-equip their air force with pilots trained to a Western standard

sada je pitanje da li se radi o f15se? u ovom textu se to nigde ne pominje, bi bili ludi da to ne urade.

...a, na osnovu ovoga još jednom vidimo da sigurno Su-30 nema 3.000 sati, kad su Su-27 iz 90-tih godina imali više od toga...

@neshaoct

hvala neshaoct na informaciji koliki resurs ima su30. da nije tebe, ne bismo znali tu cinjenicu.

jos da nam pronadjes cifru koliko kosta cas leta pa da idemo u kupovinu ovog za nas "idealnog" aviona...

samo me interesuje zasto kinezi nisu produzili resurs su27? da je bilo moguce, pretpostavljam da bi to uradili. avioni su im trajali nenormalno kratko. oceli su da ih nabavljaju 1992. danas je 2009. dakle, ako su leteli na njima 2x130 h, to mu izadje na 4420 h. moguce je da su neki vec ispunili cifru od 5000 h, ali, zasto to nije produzeno, kao sto je produzeno na nasim mig29?

Verovatno smatraju da nije isplativo, pogotovu što planiraju svoju proizvodnju zadnjeg modela F-11BS (J-11BS zavisi kako ko označava).

Sebab malo si pogresio za 260 h. Znaci 18 umesto 17 godina. Very Happy

Mislim da se lako da uvideti da su novi Su-30 koje Rusija isporucuje dosta ispred prvih su-27 koje je Kina dobila tokom '90. Zapravo mislim da su najbolje verzije Mig-29 tokom '90 bile bolje i isplativije resenje od tih Su-27.

A mozda je upravo to cena koju placas jer kupujes "jeftiniji" proizvod.

@leonard

uh, ne kontam bas, rekose da su dva pilota leteli po 130 h? mada, meni se cini da je brojka u godinama dosta manja, jer su i te isporuke trajale - nisu ih valjda dobili sve iste godine.

Prva dva koja su stigla, ukoliko su leteli na njima 2x130, trebali bi da imaju 4700h.

Nisam siguran sta se krije iza ove odluke da se povuku tih 50 Suhoj aviona umesto da im se produzi zivot. Moguce je da su Kinezi u nekim pregovorima sa Rusima i da stancaju svoje verzije pomenutog lovca. Odnosno Su-30/J-11B.

ne znam ni ja, mozda im je vek vec produzen, pa nema se kud? onda cela prica o 5000 h veku zmaja pada u vodu. i ovako, izgleda da punih 5000 h o kojima se prica nije iskorisceno, ili cifra jednostavno nije 5000 h.

svaka logika govori da iz postojecih treba izvuci koliko god se moze. imaju kinezi jos uvek isuvise onih kopija mig21, koji bi trebalo ranije da odu u penziju.
