Wind tunnels!

If you change to other industries, you really can't figure out what that thing is, the problem is that they are all power outlets, and the wind tunnel group in Cotton City is one of the largest electricity consumers in the province.

Even a few of you have undertaken the maintenance and repair of the circuits of the wind tunnel group in Cotton City before, and know that it is a top-level scientific research institution, closely related to the military and other state-level scientific research units, and is also a high-end aircraft and rocket, which is not something that ordinary people can use.

So when I heard that the twenty-third branch factory could use the wind tunnel group of cotton, the leaders of these substation companies were a little uneasy, how strong is this background to do this, it seems that what drone in front of you, well~~ reliable!

If other people are just shocked, then Zhang Ping should be shocked, you must know that in order to tow the model aircraft, he has been in the Yonghong factory for nearly two months, and he still knows a little about the inside story of aircraft development, during which he heard a designer from the Yonghong factory technology department say that if you want to completely solve it, you have to use the wind tunnel to simulate the meteorological characteristics of the Linxing River.

Unfortunately, although the Yonghong plant is an aviation factory with more than 10,000 people, it is not easy to approve the test of the wind tunnel group.

Zhang Ping was very disappointed at the time, but he couldn't help it, as the so-called interlacing is like a mountain, he didn't have any tricks.

Which Cheng thought, a branch of Yonghong Factory has such strength?etc~~ I seem to have heard from somewhere, the 23rd branch seems to be different from other branches of Yonghong Factory, and it seems to be more closely related to the local area, well~ It seems that what is said is true!

Lin Guanghua looked at the leaders of the substation company whispering in surprise one by one, and his originally straight back straightened up again, yes, he had a long face, and he thought that Lao Zhuang's words were redundant, it seems that the people at the power port are still very professional.

So he coughed and pointed the telescopic ruler in his hand to the central wing: "So according to the data, after many tests, we finally determined the layout of our TY1 UAV, the optimized straight wing, not only strengthens the structural strength of the aircraft, but also helps to improve the lift, reduce fuel consumption at the same time, increase the time to stay in the air......;

This paragraph is the focus of Lin Guanghua's preset, so he talked very hard, and he couldn't wait to take out all his ideas and experiences in designing this drone, so as to be recognized by those present.

It's a pity that the professionalism is too strong, the lift-to-drag ratio for a while, the Bethlehem formula for a while, not to mention the leaders of the substation company, even the 23rd branch of the factory is also collectively dizzy, and finally Zhang Ping looked left and right at the venue that was about to be hypnotized, and carefully interrupted Lin Guanghua's energetic introduction: "Huh...... Engineer Lin, can you first tell us how long the guide rope your plane can tow, and how many times it can tow it at a time of refueling? You know, these two are the most important things in our Linxinghe power transmission and transformation project. ”

"Ah~~"

Lin Guanghua, who was not happy enough, was a little disappointed by such a question, and he hadn't said anything about the wind tunnel test research of the most critical straight wing behind him, you must know that it was the research topic of his graduate school, the most core thing.

However, disappointment is disappointment, and the customer has to meet the requirements first, this time it was not said, and then I will say it well next time.

So Lin Guanghua nodded: "Due to the use of the 10-horsepower piston engine developed by Western Airlines, coupled with the unique structure of our aircraft, the load capacity of the TY1 UAV reaches 58 kilograms, that is, it can tow 1,600 to 2,000 meters of guidance rope under general meteorological conditions." ”

"Lin Gong, are you telling the truth?"

As soon as these words came out, Zhang Ping was immediately excited, if the plane in front of him really exceeded the traction distance of more than a thousand meters, it would really solve a big problem for them.

You must know that the cable crosses the fixed tower on the opposite bank of the Linxing River because of the terrain, there is a distance of nearly a thousand meters from the river bank, so the cable is only pulled to the opposite bank to solve part of the project, and the rest depends on the construction workers to use manpower to pull the heavy cable along the mountain road little by little, to the fixed tower nearly a thousand meters away, and then erect the operation.

This process is time-consuming and labor-intensive, and it is also a worry for the substation company, but unfortunately this difficulty can only be placed in the back row in front of crossing the Linxinghe, after all, how can it be completed with time-consuming and laborious efforts, unlike Linxinghe, even if it is hard to die, it can't be done.

Now I heard that the TY1 drone can tow more than 1,600 meters, which not only solves the problem of crossing the Linxing River, but also solves the follow-up towing cable.

In this way, the Linxinghe power transmission and transformation project immediately greatly compressed the construction period, how not to make Zhang Ping and others excited.

However, when Lin Guanghua heard this, for some reason, he suddenly became very embarrassed, Zhang Ping saw this, his heart sank suddenly, and he secretly said, it won't be this Engineer Lin bragging.

At this moment, Zhuang Jianye, who had not spoken, suddenly spoke: "That's the case, Manager Zhang, our plane is no problem, but our remote control device has average performance, theoretically it can only be effective within a range of two thousand meters, but the actual test found that the signal will weaken if it exceeds 1,500 meters, so ......"

Zhuang Jianye didn't say the latter words, but smiled apologetically at everyone, the meaning is very simple, more than a thousand meters away, we can't help it.

In fact, the 23rd branch can use the wind tunnel to build the platform of the aircraft, but the remote control device is a little blind, and there is no way but to ask someone to buy a set of imported model aircraft remote control device to make up the number, although the aircraft can fly, but the real performance can not fly.

It's like a first-class engine with an N-stream gearbox, no matter how surging the power is, it can't be transmitted, and it's embarrassing to think about it.

Lin Guanghua is generally satisfied with the ty1 drone, but he is very angry about the remote control device, and feels that this is the biggest failure of the aircraft he designed and developed, so when Zhang Ping asked him, Lin Guanghua was a little embarrassed.

Fortunately, Zhuang Jianye was thick-skinned and made additions, which made Zhang Ping relieved, but he was not disappointed, but asked: "Can it be done within 1,200 meters?"

"If visibility allows, no problem!" replied Zhuang Jianye.

"That's good, that's good!" As soon as he heard that a thousand or two meters was no problem, Zhang Ping smiled again, the distance of the fixed tower was only one thousand meters, as long as they could fix the tower, they would be very satisfied, as for one thousand or six or two thousand, they were not as good as chicken ribs.

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

"Sixty-five thousand!" Zhuang Jianye was also unambiguous, and the report was crunchy.

It's just that when the leaders of the substation company on the opposite side heard this, they all gasped, you must know that at the moment when 10,000 households are scarce, 65,000 is simply a sky-high price.
