During the Wenchuan earthquake, more than 100 military and civilian helicopters were actually deployed, while accumulating more than 1,000 flights. At that time, there were only 500 helicopters in the country, so it can be said that a quarter of the helicopters went to Wenchuan. It can be said that the Wenchuan earthquake in 2008, is China's helicopter rescue year.
Now as of 2017, there are 354 professional medical rescue helicopters in China alone, while in 2015 the number was, 27. In the middle of a major earthquake, it's the medium and heavy helicopters that are really needed.
Longer endurance and the ability to carry more equipment to hover over the destination for extended periods of time. Regular light helicopters simply can't accomplish such a task. Also, a lot of specialized equipment is needed, such as searchlights, optical/infrared imagers, radar, beacon equipment, and winches and baskets. When an earthquake occurs, the earth trembles for the first few seconds, houses sway from side to side, and continue to start collapsing and landslides. Sichuan is a hilly basin terrain, more mountains, the terrain undulation, Wenchuan is located in the west of Sichuan, is located in China's second and third step of the excessive section of the mountain undulation, canyons and gullies are numerous, just in the Longmen Mountain seismic zone, seismically active. Wenchuan earthquake, can not let the helicopter directly into, I think there are several reasons:
1, the more flat terrain is mainly concentrated in the Minjiang River riverbed along the coast, due to the collapse of many mountains, the road is interrupted, the gully on both sides of the flat riverbed into the weir, with the aftershock of the mountain tops keep falling rocks and landslides, can not make room for helicopters, even if there is not safe.2, Wenchuan more mountains, the elevation of Wenchuan is a high mountain, high altitude, the mountains are cloudy, after the earthquake weather conditions are not good for helicopters into the mountains can not provide a good line of sight forced to go in will increase the risk of death. 3, Wenchuan to enter, is a canyon area, you need to follow the Minjiang River River, through the canyon need to have experienced pilots to explore, marked out the route and obstacles in position, the earthquake occurred, there is no pilot aircraft to explore the road, there is not an accurate route, the large-scale helicopter to enter, will also increase the risk of loss of life and death. A large-scale helicopter entry would also increase the risk.
In order to race against time to save more lives and property in the disaster area, our people's army chose to parachute into, but also a helpless move, so that our young soldiers from 10,000 meters high altitude parachute with their own lives, to save other people's lives, this noble spirit, it is really worthwhile for us to learn, really should be applauded for them, do you think that the quality of the military so that you are touched by it?
