PLA F-11 fighters flying over the exercises in Tibet.
LONDON August 10 report, according to Global Strategic Network 6 reported that the Chinese F -11 fighter flight training for the first time in Tibet. J -11 is the most advanced system of planes in China. Although 90 years since the last century, China is only less than 150 which built fighter planes, but they have appeared in many unexpected places. Reported that the Chinese Air Force planes stationed in Tibet is not, despite the old F -7 regular fighters often fly in the area, but mainly in large commercial airport, temporary assignments.
Report, said the past five years, the model of friction between China and Russia to become one of the reasons. In 1995, the price of 25 billion won from the construction of 200 Russian Su -27 fighter permissions. Russia is responsible for providing engines and aerospace electronic equipment, while the Chinese side is responsible for the drawings and specifications in accordance with the Russian construction of other parts. However, the construction of 95 Su -27 fighter, the Russian side to cancel this agreement. Russia says China has used Su -27 fighter procurement project from the knowledge gained, the construction of its replica of the Soviet Union -27, that is, F -11 fighter. Russia warned that China simply copy the Russian technology, can build a low-quality aircraft. Obviously, China does not think so, its use of technology to the development of the Chinese fighter J--11.
It is believed that F -11 fighter is now more advanced equipment, including aerospace electronic equipment and some other Chinese design improvement. China to produce F -11 fighter most of the parts, the main problem is its still has to import engines. China believes that in the next five to ten years, it will get rid of dependence on Russian military aircraft engines. At present, China imports two Russian engines - priced 3.5 million U.S. dollars of the AL-31 (Su -27/30, F -11, F -10) and Unit 2.5 million U.S. dollars of the RD-93 (MiG -29 dispensed RD-33 engine in a version).
Reported that the People's Liberation Army Air Force fighter planes stationed in Tibet is not the main reason was the region's high altitude, large quantities of fuel costs as well as in Tibet and other supplies required for the maintenance of aircraft. At present, only one railway to Tibet (made recently built), and one of the few passable roads for heavy trucks.
Moreover, the PLA officers and men of altitude sickness in Tibet is the Chinese presence in Tibet fighters to a major problem. When people who grew up from the plain areas (most of the world population is so) migrate to the high mountain areas, will be insufficient oxygen due to air in such a reaction occurs. This "mountain sickness," the main symptoms of shortness of breath, a sense of direction, confusion, nosebleeds, nausea, dehydration, decreased quality of sleep and eating problems, headaches, etc., if there is "Altitude Sickness" and stay at altitude for too long time loss of labor force will slow.
Reported that the average altitude of Tibet 4100 meters. Most people can adapt to local environment, but some people can not. Most of the soldiers came to the Tibetan plateau need to spend a few days or weeks to adjust to the local environment. But if they overworked, especially long exertion, still prone to altitude sickness. This has weakened the combat effectiveness of the Chinese troops stationed in Tibet.
Researchers recently found that in the past 3 1000-6 thousand years, Tibetans have evolved to adapt to this environment. The reason these people will become the main inhabitants of Tibet, mainly because they are more robust at high altitudes. Almost all Tibetans have this gene (control red blood cell activity, to maintain adequate oxygen levels). Low elevations, but very few Chinese people these genes.
Reported that the Chinese army is now putting in a lot of time, money and effort to solve this problem. Now, most of China's Chengdu Military Region, troops are deployed in the basin of the eastern half of the points. In Chengdu, western Tibet, China has deployed 52 and 53 Mountain Brigade, and strive to maintain the ability to perform tasks of 5,000 troops. The event of emergencies, like two years ago, as 13 and 14 near the army to its base in the lowlands to send troops overseas. However, once reached heights of more than 20% of soldiers are suffering from high disease, leading to disruption of work, but commanders have been trained to adapt to this situation.
Now, based in the plateau (the Sino-Indian border highland 4,500 meters) of the Chinese troops have the training room, training room in one of 1,000 square meters, and another 3,000 square meters, the training room are in oxygen-rich state. In the training room for training of soldiers, soldiers of the body can increase the oxygen content in the blood and reduce the prevalence of risk of altitude sickness. In this way, the soldiers deployed there can stay healthy. In addition, the Department of soldiers in high altitude patrol the border areas, usually carry oxygen bottles and breathing masks.
However, so far, China can only alleviate altitude sickness, not eradicate. Taking into account the aircraft maintenance personnel awareness of requirements, and the pilots prepare for flight, coupled with logistical problems, the PLA Air Force has announced timely training in Tibet, but not the air force deployed there. However, perhaps one day the Chinese Air Force will have to fight over in Tibet, so they should be there for related training.
