F-35 Engines From United Technologies Called Unreliable by GAO
[Link mogu videti samo ulogovani korisnici]
Citat:Data from flight tests evaluated by the Government Accountability Office show the reliability of engines from the company’s Pratt & Whitney unit is “very poor (less than half of what it should be) and has limited” progress for the F-35, the costliest U.S. weapons system, the watchdog agency said in a report sent to lawmakers this month.
Citat:The GAO cited the need to make design changes to the engines and then retrofit planes already built, along with continuing flaws in the plane’s software, in a report that warned the Defense Department’s “procurement plan may not be affordable.”
As of late December, engines on the Marine Corps’ complex version of the F-35, designed for short takeoffs and vertical landings, flew about 47 hours between failures caused by engine design issues instead of the 90 hours planned for this point, according to GAO officials. Air Force and Navy model engines flew about 25 hours between failures instead of the 120 hours planned.
... i odgovor firme...
Citat:The Marine Corps model’s reliability “is at 71 percent of where it is expected to be” and “has made consistent improvement progress” since 2013, Bates said. He said the Air Force model’s engine “is at 147 percent of where it is expected at this point.”

The agency “has confused engine spec reliability and aircraft spec reliability, which are measured differently,” he said. “While the report lists some propulsion concerns,” the Pentagon has “validated our reliability performance.”

Sullivan of the GAO said Pratt & Whitney’s figures “include design changes that are validated and are now being incorporated into the engine, but have not yet been demonstrated through flight testing.”
Koje su brojke, to će se još natezati ali modernizacija motora u avionima i elektronike u već proizvedenima avionima, će skupa.
Nešto još o ceni. Stavio sam negde članak o inflaciji u vojnoj industriji, gde je navedeno, da je negde od 7% do 11%.
miljon USD LETO PLUS 10%
77,
84,7
93,17
102,487
112,7357
124,00927
136,410197
Ovako izgleda od početne cene 70 m.$ dolara i 7 godina zaostatka do 136 m.$. O te cene do prodajne su realni troškovi.

lep po dizajnu,ali ovaj i f22 (familija) nikad nece nadmasiti svedjane.....Zanima me sta se toliko cimaju sa STOVL sistemima,kad na primeru harriera se moze primetiti (ili ja bar tako mislim) da je to bas neefikasna stvar???

Bilo kako bilo ovaj avion ce uraditi posao za to sto je napravljen a to su strike misije, nije problem za USAF lose karakteristike JSFa , nego mali broj Raptora , vjerovatno kad bude dostigao broj od 700-800 u nekim napadima ce morati da polovinu aviona salju samo sa v-v raketama, F35 ima iste performance full natovaren ko i prazan dok to nije slucaj sa njegovim protivnicima mogucim sem Pak Fa..

Marinci na jedan taj brod mogu da nakrcaju bataljon pesadinaca i eskadrilu STVOL aviona, i da dejstvuju skoro nezavisno.

Pa upravo je kod STOVL verzije najveci napredak nacinjen u odnosu na prethodnika (Harijera). F-35B je supersonican i ima veci dolet. Na to ide stelt kao slag na tortu.
