News of advanced aircraft: Boeing 787 Dreamliner takes place, F-35 is shelled

Fuel leak was detected in Boeing 787 Dreamliner at Narita International Airport near Tokyo. This is not the first incident with the "Dreamliner" in recent times.

For example, Monday, January 7, at the airport after landing in Boston after the passengers left the plane, a Boeing 787 Dreamliner of Japan Airlines on fire. The fire was quickly extinguished, no casualties.

The next day at the same airport, the pilots of another "Dreamliner" the same airline had to go back to the terminal from the runway due to the fact that for a few minutes before take-off was accidentally discovered a fuel leak.

In the same "Dreamliner", owned by another Japanese airline All Nippon Airways, the past week has also been fixed a fuel leak. In addition, this plane was found several other problems.

Japanese company Japan Airlines and All Nippon Airways are one of the main buyers of the Boeing 787 Dreamliner, in total, they have bought 45 of these aircraft.

Boeing 787 Dreamliner is the brainchild of the largest American aircraft manufacturer Boeing. Planes of this series are in operation since October 2011 and they, as experts, often goes wrong.

In February 2012, representatives of Boeing warned that the fifty-five Boeing 787 may have problems with the fuselage, in July — that the five aircraft in need of repair due to a failure in the engines. There have also been cases of problems in the electrical system of the airplane, and now — a fuel leak.

F-35 Fighter Lockheed Martin's completed more than a third of planned flight tests, but still faces challenges with a helmet-mounted system pilot, a software development and integration of weapons, according to a Pentagon report of 18 pages.

According to the "military parity" with reference to agency Reuters, in the past year, the number of flight tests and special tests onboard systems exceeded the planned schedule, but still remain unsolved old problems are fixed and the newly identified shortcomings. The program made more than 20,000 special test structures and equipment, but you need to perform for about 40,000 tests.

Lockheed Martin is building three versions of the aircraft to equip the U.S. Air Force and 8 of the participating countries — Britain, Canada, Italy, Turkey, Denmark, the Netherlands, Australia and Norway. The Pentagon plans to purchase a total of 2,443 fighters of this type, although many analysts believe that, given the budget constraints, the amount can be reduced.

F-35A model for the Air Force reached a checkpoint less than 30%, due to operational constraints and problems with the weapons bay doors. The problems are also associated with a system of aerial refueling aircraft, which affected the trials of all three models of fighter.

Boarding the plane, reducing its ESR, faced with a "peeling" in the execution of high-speed high-altitude flights due to higher than expected temperature regimes, which are calculated on the cover. Version of the F-35B for the Marine Corps flew more than planned, but reached a checkpoint less than 49% due to problems with the weapons bay doors and the lift fan motor when the vertical mode during landing. Also revealed few cracks in the lower part of the cell, whereby the suspended fly in December.

Version of the F-35C for carrier-based naval aviation faced challenges to transfer video to the ships, and during a live-fire revealed serious problems with the cooling system, which is currently being addressed.

More work is required to protect the fuel tanks from the explosion, which could cause a lightning strike, it is reported that currently flying is prohibited at a distance of 25 km from molnieopasnyh areas.

These issues are the company office and the Pentagon F-35 program has not yet commented.
