    The wind tunnel group!

    "If you were in other industries, you probably wouldn't be able to figure out what that thing is. The problem is that they are all in the electricity department, and the wind tunnel group in Mianhua City is one of the largest consumers of electricity in the province.

    Some of you here have even been responsible for the maintenance and emergency repair work of the wind tunnel group in Mianmian City before. They know that it is a top scientific research institution and has close ties with the military and other national-level scientific research units. It also produces aircraft and rockets.  High-end, not something that ordinary people can use.

    So when they heard that the 23rd Factory could use cotton's wind tunnel group, the leaders of these power substation companies became a little uneasy. What kind of strong background does it take to do this? It seems that there is some kind of drone in front of them.  Well~~reliable!

    If others were just shocked, then Zhang Ping should be shocked. You must know that he spent nearly two months in Yonghong Factory for towing model aircraft, and he also knew a little bit about the inside story of aircraft development. During this period, he  I heard a designer from the process department of Yonghong Factory say that if we want to completely solve the problem, we need to use a wind tunnel to simulate the meteorological characteristics of Linxinghe.

    ¡°It¡¯s a pity that even though Yonghong Factory is an aviation factory with more than 10,000 people, it is not easy to get approval for the wind tunnel group test.

    Zhang Ping was quite disappointed at the time, but there was nothing he could do about it. As the saying goes, there was no way he could make any moves.

    How could you imagine that a branch factory affiliated with Yonghong Factory would have such strength?  Wait~~ I seem to have heard it somewhere. The 23rd Factory seems to be different from other branches of the Yonghong Factory. It seems to be more closely connected with the local area. Well~ It seems that what I said is true!

    Lin Guanghua watched the leaders of the power substation company whispering in surprise. His originally straight back straightened up again. Yes, he had a long face. He thought that what Lao Zhuang added was superfluous. It seemed that the power department  The people are still very professional.

    Then he coughed and pointed the telescopic ruler in his hand to the center wing: "So based on the data and after many tests, we finally determined the layout of our ty-1 drone. The optimized straight wings not only strengthened the aircraft structure  Strength, and the optimized airfoil also helps to increase lift, reducing fuel consumption and increasing air time; at the same time, we combine the tail beam and the wing to form double vertical tails, which stabilizes the fuselage.  It can also increase the maneuverability of the aircraft"

    This paragraph was Lin Guanghua¡¯s preset focus, so he talked about it extremely hard. He wanted to share all his thoughts and experiences in designing this drone, so as to gain the recognition of everyone present.

    It's a pity that the professionalism is too strong, sometimes the lift-to-drag ratio, sometimes the Bethlehem formula, not to mention the leaders of the substation company, even the No. 23 Plant was collectively confused, and in the end it was Zhang Ping who was around  He looked at the venue, which was almost hypnotized, and carefully interrupted Lin Guanghua's enthusiastic introduction: "Um Engineer Lin, can you first tell me how long the guide rope your aircraft can tow, and how long it can tow with one refueling?"  How many times? You know, these two items are the most important in our Linxinghe power transmission and transformation project."

    "Ah~~"

    Lin Guanghua, who was still not happy enough, was a little disappointed when he was asked this question. He has not yet talked about the most critical wind tunnel test study of the straight wing. You must know that it is the research topic of his graduate student and the core thing.

    ???????????????????????????????????? Disappointment is a disappointment. Customers have to satisfy their requirements first. If we didn¡¯t get it this time, we¡¯ll talk about it properly next time.

    So Lin Guanghua nodded: "Due to the use of the 10-horsepower piston engine developed by Xi'an Airlines, coupled with the unique structure of our aircraft, the load capacity of the ty-1 drone reaches 58 kilograms. In other words, it can fly under normal weather conditions.  Come down and pull the guide rope of 1,600 to 2,000 meters."

    "Lin Gong, are you telling the truth?"

    As soon as these words came out, Zhang Ping immediately became excited. If the plane in front of him really had a towing distance of more than one thousand meters, it would really solve a big problem for them.

    You must know that the cables crossing the fixed tower on the other side of the Linxing River are nearly a kilometer away from the river bank due to terrain reasons. Therefore, pulling the cables to the other side only solves part of the project. The rest depends on the construction workers using manpower to move the heavy towers.  The cables were dragged along the mountain road little by little to the fixed tower nearly a kilometer away, and then the erection operation was carried out.

    This process is time-consuming and labor-intensive, and it also worries everyone in the power substation company. Unfortunately, this difficulty can only be pushed back before crossing the Linxing River. After all, it can be completed even if it is time-consuming and labor-intensive. Unlike Linxinghe, it can be done even if you put in the utmost effort.  indefinite.

    Now I heard that the ty-1 drone can tow more than 1,600 meters, which not only solves the problem of crossing the Linxing River, but also solves the subsequent towing cable.

    As a result, the construction period of the Linxinghe power transmission and transformation project will be greatly shortened immediately. How can Zhang Ping and others not be excited?

    However, when Lin Guanghua heard this, he didn¡¯t knowHe suddenly became very embarrassed. When Zhang Ping saw this, his heart suddenly sank and he thought to himself, Engineer Lin couldn't be bragging.

    At this moment, Zhuang Jianye, who had been silent, suddenly said: "That's it, Manager Zhang, our aircraft is fine, but our remote control device has average performance. In theory, it can only be effective within a range of two thousand meters.  Actual tests found that the signal will weaken beyond 1,500 meters, so"

    Zhuang Jianye didn¡¯t say the next words, but he smiled apologetically at everyone. The meaning was simple, there was nothing we could do if the distance was more than one thousand meters.

    In fact, this is also the case. The 23rd Factory can use the wind tunnel to build the aircraft platform, but the remote control device is a bit blind. It has no choice but to ask someone to buy a set of imported aircraft model remote control devices to make up the number. Although it can make the aircraft  It can fly, but the real performance cannot be achieved.

    "It's like a first-class engine equipped with an n-speed gearbox. No matter how powerful the power is, it can't be transmitted. It's embarrassing to think about it.

    Lin Guanghua is generally satisfied with the ty-1 UAV, but he is very worried about the remote control device. He feels that this is the biggest failure of the aircraft he designed and developed, so when Zhang Ping asked about it, Lin Guanghua was a little embarrassed to talk about it.

    Fortunately, Zhuang Jianye was thick-skinned and made a supplement, which made Zhang Ping and others relieved. However, they were not disappointed, but asked: "Can it be done within 1,200 meters?"

    ¡°If visibility permits, no problem!¡± Zhuang Jianye replied.

    "That's good, that's good!" Zhang Ping smiled again when he heard that one thousand two meters was no problem. The distance between the fixed towers was only one thousand meters. As long as they could reach the fixed towers, they would be very satisfied. As for one  Six thousand or two thousand, in the end, it is worse than worthless to them.

    So he laughed and asked a key question: "How much does your plane cost?"

    "Sixty-five thousand!" Zhuang Jianye was also unambiguous, and his response was loud and clear.

    However, when the leaders of the power substation company across the street heard this, they all took a breath. You must know that at a time when households with ten thousand yuan are scarce, sixty-five thousand yuan is simply a sky-high price.
