Take Off My Aviation Era

"After research, we found that this new model of your aircraft is very suitable for flying in high altitude areas." After entering the lounge, a few orderly soldiers served a few cups of hot tea and Wu Changcheng took a sip before continuing the introduction. Looking at the situation of the army: "Our Air Force believes that once this aircraft can be successfully developed, it will have a qualitative improvement in the logistics support capability of our army in plateau areas, especially in the border areas of Tibet..."

　　 Then Wu Changcheng talked about the intentions of the chief of the Air Force and the thoughts of several of their review panel.

Tibetan areas, especially the southern border areas of Tibetan areas, are not only often affected by the border situation, but also have extremely backward economic levels. Let’s take the southernmost counties. It has been more than 30 years since the founding of the country, and there is even an external highway. nothing.

　　 This has led to a frequent shortage of supplies for the border officers and soldiers stationed here all year round, and the livelihood of local residents is also difficult to guarantee.

　　 It’s better in summer. With mules, horses and livestock along the winding mountain roads, they can also transport some salt, food, medicine, etc. from the hinterland of Tibet.

　　In the winter, when the mountains are closed by heavy snow, several counties in the southern region completely cut off traffic from the hinterland of Tibet.

　　 It doesn’t usually matter. I’m afraid that such uncertainties as natural disasters will happen. I’ll leave it alone. Everyone at the border can make up for it. Natural disasters happen from time to time. At this time, cutting off land transportation means cutting off the passage of life.

　　 Therefore, air transport shoulders the important task of maintaining the links between the southern region and opening up the passage of life.

　　 It is precisely this problem that has plagued the country for a long time. There is no other reason. It is really impossible to find a plane that can fly over the mountains at an altitude of 7,000 meters and land accurately in southern Tibet.

　　 Therefore, since the 1960s, the country has always used the deterrence left by the foreign self-defense counterattack that year; but it is really powerless to deal with natural disasters.

　　 It was not until the S-70 "Black Hawk" helicopter was introduced from the United States in the 1980s that it was the first time that it had the ability to deliver winter supplies to southern Tibet.

　　 But having it does not mean that it can completely solve the problem. The first introduced S-70 "Black Hawk" helicopters totaled only 24, which is insufficient in number.

Secondly, although the S-70 "Black Hawk" helicopter can fly on the plateau, it is based on a powerful turboshaft engine, but the other supporting facilities do not have this condition. The most typical one is the S-70 "Black Hawk" helicopter. Oxygen and heat preservation facilities are so lacking that the pilots of the S-70 "Black Hawk" helicopter have to wear thick aviation suits and fly over 7,000-meter high-altitude mountains with oxygen masks to and from southern Tibet. And the hinterland of Tibet.

Finally, no matter how strong the performance of the S-70 "Black Hawk" helicopter is, it will be a helicopter after all, not to mention its inherent short range, and its ability to resist turbulence in high-altitude mountainous areas is not strong; therefore, it takes several transitions for each mission. Enter the mission forward base.

　　 During the mission, he took great risks. There was even a plane crash and death accident the year before, which caused great losses.

All these make the Air Force an urgent need for a model that can carry a certain amount of cargo, has a certain long-distance flight capability, has a practical ceiling of more than 8,000 meters, and has the basic performance of flying at higher altitudes and mountains, while being able to fly freely on a simple runway of hundreds of meters Landing fixed-wing, low-cost, multi-purpose small transport aircraft.

　　As the main aircraft type for supply and transportation to southern Tibet.

　　 If these requirements are placed inland, Old Fortune 5 can be easily completed, but once on the plateau, these indicators are not generally harsh.

　　 You must know that satisfying these conditions at the same time can not be solved by simply increasing the engine horsepower. If it is so simple, the Allied hump route during World War II would not be called a death transport line by pilots.

　　 It is because the Himalayas are not only high in elevation, but the internal turbulence is also extremely complicated, and it is possible to be involved in it by accident.

　　 Lightly makes the airplane's flight attitude unstable. In severe cases, it can directly freeze the moving parts of the airplane. If there is no efficient and fast de-icing system, the airplane will immediately crash like an icy head.

　　 In addition, the low temperature and hypoxia in high altitude areas, how to solve the basic oxygen supply and temperature control is also a problem.

　　Of course, there are also highly adaptable short-distance takeoff and landing capabilities. Fortunately, the hinterland of Tibetan areas has complex terrain and lack of materials. At most, a sand-gravel flat land several hundred meters long can be leveled. This is still in summer.

　　 In winter, the mountains are covered by heavy snow, and even such flat land is hard to find. You can only take off and land on the snowy field.

　　 This requires the aircraft to be extremely adaptable.

Such a difficult index, let alone difficult to achieve in China, or even looking at the world, it is difficult to find a suitable one. It is not capable of short takeoff and landing, and the carrying capacity and practical ceiling are not up to the standard; it is the flying altitude that can easily exceed 10,000 meters. , But a medium-sized runway with a takeoff and landing distance of at least one kilometer.

　　 In short, nothing can meet the requirements of the Air Force.

　　 Just as the Air Force was preparing to wait another two years to see if there was a suitable aircraft type to perform this task in the 1990s, Wu Changcheng, Ding Laixiang and others submitted the basic information of the improved Yun-5 to the Air Force.

　　A few air force chiefs took a look. Isn’t this what they want these years, with a load of 1.8 tons, a maximum flight distance of 1,500 kilometers, and a practical ceiling of 7,500 meters.

　　The most important thing is the pioneering application of key technologies for high-altitude flight such as rapid de-icing of the wing surface, pressurized cabin and air circulation on the improved Yun-5.

　　 What’s even better is that this aircraft has inherited the excellent performance of the old Yun 5 short take-off and landing, enough to take off and land on the complex terrain in southern Tibet.

Of course ~www.readwn.com~ Although the improved Yun 5 is very satisfied with the air force chiefs in terms of basic performance, some details still make them feel a little unsatisfactory. The first is the practical ceiling. 7500 meters is not low, but If you know that many of the mountains in the southern part of the Tibetan area are high mountains above 7,000 meters above sea level, this practical ceiling is somewhat pediatric, so it is best to be able to achieve more than 8,000 meters, so as not to rub the peak Erfei.

The second is the voyage. The 1,500 meters is still a bit short. If it can be increased to more than 2,200 kilometers, it will be possible to fly directly from the capital of Tibet to Medog in the south of Tibet without refueling. Take off easily and return to the capital of Tibet.

"If these two points can be achieved, the troops will be able to reduce the input of military stations along the southern part of the Tibetan area, and directly take off from the capital of the Tibetan area to provide support to the southern part of the Tibetan area. Based on this, we feel that the improved Yun-5 has followed Yun 5 doesn’t matter much, so when the head of the Air Force came to investigate not long ago, several of us proposed that the improved Yun 5 be officially renamed to Yun 6. The head of the Air Force agreed in principle."

Talking about Wu Changcheng, looking at Zhuang Jianye on the opposite side: "For this reason, the Air Force is ready to allocate funds to assist your Ascendas Headquarters to further improve the Yun-6. If everything meets the requirements of the Air Force, I can’t guarantee the purchase of forty aircraft. I don’t think scale is a problem."

The models have been renamed, and the funding is very happy. The most important thing is that they don’t shy away from the purchase amount. What can Zhuang Jianye say, simply pat his chest and say in awe: "Please rest assured, the chiefs of the Air Force, I represent Ascendas Aviation. The manufacturing company took a stand to ensure that the development of the Yun-6 is completed in accordance with the requirements of the Air Force in quality and quantity."
