U.S. F22 due to the oxygen supply system problems forced grounded indefinitely
data for: the old” Raptor “F22 has been life-long fly
中广网 Beijing on May 7, according to Voice of China” peak evening news “report, May 12, 2005, with the The first type of F-22 combat aircraft delivered to U.S. Langley Air Force Base 27th Fighter Squadron, known as the “Raptor” the F22 was put into active service, also marks the world is beginning to enter the “invisible Air Force Times.”
Moderator: However, in the F22 into active duty for six years, the No. 6 local time, on the F22, but the U.S. Pentagon has made “grounded indefinitely” decision. So why make such a decision? Let’s connect the Voice of China Wang Zongying international news editor.
Moderator: Wang Zongying, why the indefinite grounding of the U.S. Air Force F22? Tell us about the relevant circumstances.
Wang Zongying: The Air Force grounded the reasons given to the machine room F22 Raptor fighter aircraft oxygen system, oxygen supply problems, so the U.S. military is checking F22, focus is on oxygen check on the system. We know that before November 17 of last year, when there is a F22 fault occurred because the oxygen system is crashed in Alaska. Investigation shows the pilot before the incident are likely to be a serious lack of oxygen, followed by entering a coma, it was decided to F22 Raptor Air Force fighter jets in routine training flight when the height restrictions, the specific height is limited to less than 7600 m .
other defects as well for the F22 report revealed that its ability to communicate is very limited, only a single squadron and the other F22 stand and exchange of information, but last year the United States decided to completely give up F22 communications system upgrade project, this time to fully grounded indefinitely, the news came out, most users commented that the issue would not be so simple, it is estimated the United States to upgrade the.
F22 Raptor is a fighter from the U.S. Lockheed Martin, Boeing and General Dynamics and other companies jointly designed heavy-duty U.S. Air Force stealth fighter, the main task is to achieve and maintain air superiority battle, F22, 2005 U.S. Air Force began to join the grouping, to replace the main grouping of the previous era British fighter F15, F22 is a contemporary one of the most expensive fighter aircraft, the device has a supersonic cruise, BVR combat, high mobility, the radar and infrared stealth characteristics, it is estimated that the operational capacity of the older generation F15 of 2 to 4 times the dominant group is one of the new generation heavy fighter, and after the U.S. movie “Transformers” turned in front of spider that is F22 fighters.
crashed due to a fault, following after the previous year, in March, F22 “Raptor” fighter’s image has again been hit. Air strikes against Libya in which the United States has a 6-year-old’s F-22 did not show up to accept reality check.
In fact, since 2005 the U.S. Air Force equipped with F-22 has been such a fighter from a U.S. military did not participate in any armed conflict. So what exactly is the absence of defects so that F22 has been real? The reason behind the grounding of what is?
National Defense University professor Zhang Zhaozhong: F22 service since a lot of people on the plane there is a dispute, some of it’s own technical defects, such as communications, control, cooperative engagement capability is a saying, but also There is an argument that is grounded in fact this is quietly upgrading, I feel that two statements are a problem, from my experience speaking or a hidden world’s most advanced fighter aircraft, it is the poor performance of communication because it is unwilling to communicate with others, there is a not rule out that this aircraft is now in borrowed space such as the X37 and other new technology aircraft, the fifth-generation fighter for the foundation, but for now this is good grounding like a very simple technical problems.
put into service as the world’s first fourth-generation fighter aircraft, F-22 in the landmark aviation history, many aviation enthusiasts and even that will be the U.S. F-22 fighter of the highest level of development point, Zhang Zhaozhong that, F22 should soon be missed, but he is still under development which we outlined the contours of the U.S. fifth generation fighter.
Zhang Zhaozhong: I believe that before the F22 grounded for too long it can go around, F22 and now serving a total of U.S. Air Force bought 165, the production line had stopped, about five generations of machine problems four generations of machines in service at the same time the United States launched the next generation fighter, and now the next generation of fighter jets still do not see a profile, I have been a view that the biggest difference between the fifth-generation fighter aircraft may be unmanned-based, strengthened on the basis of the stealth speed increase, the rate of future space may be mentioned that the speed of the aircraft, a dozen Mach, and can travel between space, this may become a feature of future Five fighters.
