Fighter F-35 Lockheed Martin’s graduated more than a third of planned flight tests, but as before encounters with neuvvyazkami helmet Pilot system, software development and integration of weapons, according to a Pentagon report of 18 pages. Now this report agency Reuters.
In 2012, the number of flight tests and special tests onboard systems exceeded the planned schedule, but still remain some old prepyadstviya newly identified and fixed bugs. Within applets made more than 20 thousand special test structures and equipment, but you must perform another 40 thousand tests.
Lockheed Martin is building three versions of the aircraft to equip U.S. military aircraft and 8 programs from participating countries — Britain, Canada, Italy, Turkey, Denmark, the Netherlands, Australia and Norway. The Pentagon plans to purchase a total difficulties of this type of fighter in 2443, although many analysts believe that, given the budget constraints, the amount can be reduced.
Still reported the highest level of «duplication and overlap» in the program development, production and testing, which, in the views of the 1st of dignitaries associated with «abuse of authority».
The report states that in 2012 was conducted flight tests in 1092, which is 18% more than planned (927 flights).
Model F-35A for the Air Force reached the checkpoint less than 30%, due to operational constraints and neuvvyazkami with wings compartment guns. Tasks are also associated with a system of aerial refueling aircraft, which affected the trials of all 3 models of fighter.
Stealth aircraft skin, which makes it virtually invisible to enemy radar, faced with «exfoliation» in the execution of high-speed high-altitude flights because of the larger than expected temperature regimes for which coverage was calculated. Version F-35B Marine Corps flew more than planned, but reached the checkpoint less than 49% due to problems with the bay doors guns and lift fan motor when the vertical mode during landing. Also identified several cracks in the lower part of the cell, resulting in December suspended flights.
Aircraft weight remains relatively unchanged over the past year, but the average time-critical failures increased, the report said.
Version F-35C carrier-based aircraft for the Navy faced neuvvyazkami video transmission on ships, and during a live-fire were identified severe problems with the cooling system, which currently being addressed.
Required more work to protect the fuel tank from the explosion, which could cause a lightning strike, it is reported that the currently banned flights at a distance of 25 km from molnieopasnyh areas.
