Chapter 1458 The Hearts of Brothers on the Plateau: Part

Because it was a modification of an existing model, the modification work of the high-altitude unmanned helicopter went very smoothly and quickly, and it was said that it could be completed in a week. However, a professional team is a professional team, and they are not comparable to the two students Wang Tao and Li Dong. In the following week, the engineering and technical team not only modified the UAV, but also conducted high-altitude performance simulation tests on the engine and rotor in the laboratory.

Looking at the test report in front of him, Zhang Qihang was very happy: "The test results are very ideal, huh? Did you optimize the rotor again?"

The test report in front of us shows that in the simulation test, with a total load of 300 kilograms (fuel + load), this unmanned helicopter can still achieve a maximum hovering altitude of 6200 meters in the absence of ground effect. Moreover, at this altitude, the newly replaced turbocharger and the professionally tuned closed electronic fuel injection system allow the engine to still operate normally.

"Yes," Zhang Jiwen said with a smile, "As long as it is the plateau blade solution proposed by Wang Tao and his team, it is good, but it is more suitable for multi-rotor drones. It is not suitable for our single-rotor large unmanned helicopter with a rotor diameter of more than 4 meters. We optimized it again. After the optimization, the efficiency of the new blade increased by 2.5%, so it can achieve a maximum hovering altitude of 6200 meters."

Zhang Qihang nodded and asked, "Why? Do you still want to go to the same place as last time to conduct the actual test?"

  After the laboratory test is completed, the actual test will be carried out. Considering the weight of Huateng Group and its relationship with various departments, he can just call Director Liu in charge of the Air Traffic Control Bureau and tell him. As for having him come and talk to me in person?

Therefore, Zhang Qihang was very curious about Zhang Jiwen's purpose in coming to see him: Could it be that he wanted to take the prototype to the same place as last time and show it to the leaders of the garrison system?

“No thanks,” Zhang Jiwen waved his hand with a wry smile, “To be honest, Mr. Zhang, after hearing about what happened to Xiao Wang and his team last time, I don’t dare to go… This is what happened. I have already informed Director Liu of the Air Traffic Control Bureau. This test will be held in our group. For safety reasons, Director Liu specially arranged for someone to send a corner reflector. In this way, the Air Traffic Control Bureau can understand the situation of our test through this corner reflector.

Oh, by the way, Director Liu has specially allocated a small area of ​​airspace for us for this test."

"Um……"

  Zhang Qihang nodded, and Zhang Jiwen continued: Since even the test airspace is prepared for you, you can just go about your business. Why are you looking for me?

"hey-hey……"

Zhang Jiwen chuckled twice and said a little embarrassedly: "Boss Zhang, after the test is completed this time, according to the plan, we are going to conduct a field test on the plateau.

We are all thinking about doing a plateau test project. Why don't you say hello to the leaders of the garrison system? While we are doing the test, we can also deliver some things to those outposts that are currently unable to get supplies. This can be considered as both testing and helping."

"You, you, you..."

Zhang Qihang nodded at Zhang Jiwen twice and couldn't help laughing: "Old Zhang, I'm embarrassed to say anything to you. Are you guys thinking of advertising at the same time?"

"Hey hey hey..."

Zhang Jiwen scratched his head and smiled embarrassedly.

  Some brothers are curious. What Zhang Jiwen wants to do is obviously a good thing. Can't he just tell the garrison system directly? Why does he still need to ask Zhang Qihang for help to greet the leaders of the garrison system?

The reason is actually very simple. Even if it is a good thing, it depends on who does it.

What is the garrison system for? It is a department that protects our country. It is such a serious department. If you say you want to help, I will let you help. Who do you think you are?

  Even if the garrison system introduced a lot of two-seat helicopters and drones purchased from Huateng Group, it would not work!

Simply put, Zhang Jiwen’s weight is not enough!

But if Zhang Qihang said hello to the garrison system, it would be different. Only Zhang Qihang and Feng Guoqing were qualified to represent the huge Huateng Industrial Group, not to mention the background of Zhang Qihang's father-in-law's family. These factors added together meant that in the eyes of the garrison system leaders, Zhang Qihang was one of their own.

Zhang Jiwen also knew this, so he asked his boss to help say hello.

Zhang Qihang did not hesitate and agreed immediately: "No problem, I will talk to the leaders later and ask them to support our work." At this point, Zhang Qihang smiled and joked with Zhang Jiwen: "Maybe after your advertising, we can get an order for dozens of aircraft."

"I think so too," Zhang Jiwen nodded repeatedly. "Even the Z-11 can only hover at a maximum altitude of 5200 meters. But how much does it cost to deploy a Z-11? How much does it cost to deploy our helicopter?"

........................

Everything went smoothly in this test. The maximum hovering altitude when empty was 6200 meters, and the maximum hovering altitude when fully loaded was 5800 meters. The test results made Zhang Qihang very satisfied.

He picked up the phone and dialed. After a while, the call was connected. After a few greetings, Zhang Qihang asked, "Old Wei, I need your help with something, the boss of Luhang."

Comrade Lao Wei on the other end of the phone said cheerfully, "Mr. Zhang, you are too polite. Tell me, what is it?"

"The UAV company under our group has developed a high-altitude unmanned helicopter with a maximum payload of 300 kg. During previous tests, it could achieve a hovering altitude of 300 meters with a full load of 5800 kg. Next, we will conduct actual tests on the plateau..."

Before he finished speaking, Zhang Qihang heard something falling to the ground. At the same time, Wei Tuan's anxious voice reached Zhang Qihang's ears: "Mr. Zhang, what did you just say? What is the hovering altitude? What is the maximum load?"

As a leader of the Army Aviation System on duty in the plateau areas, Wei Tuan knows all too well what the two figures of 6200 meters of hovering altitude and 300 kilograms of payload mean to the brothers who are defending their country in the most difficult places.

"Wei Tuan, you heard me right, and I didn't say anything wrong either," Zhang Qihang said calmly on the phone. "It's a maximum hovering altitude of 6200 meters. With a total of 300 kilograms of fuel and payload, it can also reach a maximum out-of-ground-effect hovering altitude of 5800 meters."

"What about the flight speed?" Wei Tuan's voice was full of anxiety: "What is the fuel consumption?"

"The cruising speed is 100 kilometers per hour and the fuel consumption is 25 liters per hour."
