Turkey Postpones Order for Its First Two F-35 Fighters
http://www.defensenews.com/article/20130111/DEFREG.....dyssey=tab|topnews|text|FRONTPAGE
Citat:“Due to the current state of the JSF (Joint Strike Fighter) ... and the rising cost ... it was decided to postpone the order placed on Jan 5, 2012, for the two aircraft,” the Undersecretariat for Defence Industry (SSM) said in a statement.
The SSM, the public body responsible for Turkey’s arms purchases, said the decision was taken because the technical capabilities of the aircraft were ”not at the desired level yet.”

Hot Stuff: The F-35 Just Became 25% More Vulnerable

Citat:Two changes designed to cut the plane’s weight by 11 pounds have made it 25% more vulnerable to exploding in mid-air, and other unfavorable outcomes.

Recent tests show that removing nine pounds of fueldraulic fuses and two pounds coolant shutoff valves “results in a 25 percent increase in aircraft vulnerability.”

Citat: Notes the DOT&E report about those 32 ounces of valves:

The aircraft uses flammable PAO [Polyalphaolefin] in the avionics coolant system, which has a large footprint on the F-35. The threat in this ballistic test ruptured the PAO pressure line in the area just below the cockpit, causing a sustained PAO‑based fire with a leak rate of 2.2 gallons per minute (gpm). The program assessed that a similar event in flight would likely cause an immediate incapacitation and loss of the pilot and aircraft. The test article, like the production design, lacks a PAO shutoff system to mitigate this vulnerability.

The F-35’s developers are reconsidering that decision.

I ne samo to - dodatno su "olabavili" specifikacije vezane za opterecenje i transonicno ubrzanje (0,8-1,2Maha). Kod F-35C prvobitno je navedeno/trazeno vreme ubrzanja bilo 65 sek. a stvarno je 43 sek. duze, tj. celih 108 sek. (vise od minut ipo). Ovako lose ubrzanje dovodi do brzeg i veceg utroska goriva, pa se radijus dejstva znatno smanjuje.

Evo malo kvalitetne pljuvacine, ovo sad Carlo Kop cita uz kafu. Izvestaj za 2012 http://www.cnbc.com/id/100376019

Citat:The program has already completed over 20,000 specific tests of items and capabilities on the plane, but has 39,579 more such tests to go.

B i C su obavili i vise testova nego planirano

Citat:The report said the program conducted 1,092 flight tests in 2012, 18 percent more than the 927 flight tests planned, running more tests than scheduled for the Marine Corps B-model and the Navy's C-model or carrier variant.


Problemi sa A verzijom, opet se ljusti...

Citat:But it fell short of the flight tests planned for the Air Force's conventional takeoff A-model. That model completed 30 percent less test points than planned due to operating limits on the plane and problems with the weapon bay doors, it said.

It said flight tests were also limited by problems with the air refueling system, which led to restrictions on all A-model planes and required new instrumentation to isolate the cause.

The plane's stealthy coatings - which make it nearly invisible to enemy radars - were also peeling off on horizontal tail surfaces due to higher-than-expected temperatures during high-speed, high-altitude flights, the report said.

Problemi sa B

Citat:The Marine Corps version of the plane flew more than planned but lagged its target for test points by 49 percent due to issues with the weapon bay doors and an engine lift fan needed for that B-model's vertical landings, the report said.

Citat:Durability testing of the Marine's B-model had to be halted in December after multiple (zabranjeno)s were found on the underside of the plane's fuselage, the report said.

Problemi sa C

Citat:It also cited problems with the ability of the Navy's C-model to transfer video and imagery data to ships, and said one live-fire test revealed a potentially serious problem with the coolant system, which was now being addressed.

A inace kaciga ne radi i dalje, integracija oruzja kasni i nesme da pridje gromu da ga Djenka nebi slucajno spalio...

Citat:It said the complex helmet that integrates data for the pilot from all the plane's sensors was still facing issues, as is a computerized logistics system.

Weapons integration testing was delayed by a number of factors, including problems with the performance of a radar system and in tracking targets.

More work was also needed on a system aimed at protecting the plane from fuel tank explosions caused by lightning, the report concluded, noting that flight operations were currently banned within 25 miles of known lightning conditions.

Nije se nesto ugojio u 2012. ali je poceo da crkava cesce

Citat:The weight of the new plane remained fairly steady over the past year, and the mean time between critical failures increased, but the plane's performance remained below the level expected for this point in the program, the report said.

Otkazi su ređi, ali i dalje je ispod predviđenog nivoa.
