Chapter 1459 The Hearts of Brothers on the Plateau:

Plateau, a certain Army Aviation base.

Wei Tuan looked at the drone in front of him, his face full of curiosity and surprise: "My goodness, are drones this big now?"

Professor Wu, the leader of the team, smiled and said, "This is just the beginning. Our group is currently helping the maritime supervision department develop a fixed-wing long-flight UAV with a maximum range of more than 8000 kilometers and a full-load range of nearly 5000 kilometers.

As for this unmanned helicopter, Wei Tuan, didn't you work in the Army Aviation Unit under Shungeng J District before? You should know that the Army Aviation Units under the major J Districts are equipped with an ultra-light two-seat training aircraft. This unmanned aircraft is modified based on that training aircraft. The power system, transmission system and rotor system are all universal. "

Wei Tuan, who had served in the Army Aviation Unit under Shungeng J District for many years, was very familiar with the ultra-light two-seat training helicopter. He usually flew the small plane around in the sky to get familiar with the feel when he had nothing to do. Now, after hearing what Professor Wu said, he suddenly realized: "Is it improved on the basis of that training aircraft? I was wondering how there could be an unmanned helicopter with such a large load. Now I understand it now. On the basis of that training aircraft, the weight of two pilots, as well as the supporting instruments and control systems, plus the fuel, it has increased by 300 kilograms."

Professor Wu smiled and nodded: "We thought so when we designed this drone. It can also increase the commonality of parts and reduce maintenance costs."

"Yes, that's right. It's important to increase the commonality of parts." At this point, Wei Tuan suddenly thought of something and asked hurriedly, "Professor Wu, our unit was not equipped with that training aircraft because of the high altitude. Everyone feels very sorry. Now that you have developed a high-altitude version based on this drone, can this set of modified parts also be used on that training aircraft?"

Since the introduction of this training aircraft, this ultralight helicopter used for daily basic subject training has been very popular among aviation units on the mainland, because it can not only complete the most entry-level task of instructors leading students, but also after adding short wings similar to the Z-9 armed model, it can even carry rocket pods, airborne Red Arrow-8 anti-tank missiles and other weapons in a single-person driving state. Although not many weapons are carried and the total weight is controlled below 120 kilograms, it is enough for basic training.

  Best of all, its cost of purchase and daily use is very low!

Previously, various mainland aviation units could only use expensive helicopters such as the Z-9 and Mi-17/171 for daily training. With limited funds, everyone was counting on their fingers, and it was a great achievement if they could reach 180 flight hours per year. But after being equipped with this training aircraft, everyone can fly freely and to their heart's content, and the annual flight hours can easily reach 400 flight hours.

尽管这400个飞行小时可能是在直9或者米-17/171上面飞120个小时，加上在训练机上飞的280个小时，但有了这多出来的280个飞行小时的经验，总比每年只能飞150个小时来的更有效果。

Therefore, many comrades in the army aviation units, including the Wei Regiment, like the training aircraft produced by the Huateng Group very much. This training aircraft is good in every way except that its flight altitude is limited, and it can only fly to a maximum altitude of 3000 meters.

  This flight altitude certainly has no impact on comrades in other J Zone subordinate aviation units, and no one thinks this is a problem: it is just an entry-level helicopter used for basic flight training and to develop flying skills, so what more can you demand of it?

But the guards who moved to the new unit felt very uncomfortable!

  For Wei Tuan, who used to fly around in the sky every day, after arriving at the plateau, he no longer had a training aircraft to use. He could not fly around whenever he wanted. He felt as anxious as a smoker who had not smoked for a long time. However, the performance of the training aircraft was there, so there was no other way. Wei Tuan gave up the idea. But now, after hearing Professor Wu say that the drone with the same power system as the training aircraft could fly to an altitude of more than 6000 meters after modification, and could take off and land normally in the plateau, he immediately became uneasy: Can this modification also be used on the training aircraft?

"Of course it is possible."

Professor Wu gave an affirmative answer.

  Is it really possible? !

Wei Tuan was surprised and delighted, and asked quickly: "Professor, when can you help us change it? You don't know that after arriving at the base here, the training can't be used, which is really inconvenient."

"We have also thought about this issue and are now advancing work in this area," Professor Wu explained. "Our plan is to first test this plateau-type propeller blade on a drone. If it works properly on the drone and there are no problems, we will transplant this set of propeller blades and the corresponding engine modification solution to a manned helicopter, and then apply for airworthiness certification...

You also understand, Wei Tuan, that manned helicopters are different from unmanned helicopters. If an unmanned helicopter crashes, it's just a small loss of property at most, but if a manned helicopter crashes, it means one or two lives have been lost. We must be careful and strictly follow the procedures to do this."

The same is true...

Although Wei Tuan was very anxious, he also knew that what Professor Wu said made sense. If a drone crashed, it crashed, but a manned helicopter was different and had to go through the certification process.

Although this is the truth, Wei Tuan is still very anxious: "Then... Professor Wu, how long do you think it will take to complete this certification?"

Upon hearing this, Professor Wu couldn't help but laugh: It seems that this Wei Tuan really likes that training machine.

After thinking for a while, Professor Wu said, "Our two-seater helicopter is a certified model. According to the current aviation aircraft management regulations, modifications of this level are considered supplementary models of existing models. The certification process will be faster. Under normal circumstances, it will take about two years."

At this point, Professor Wu glanced at Wei Tuan and said with a smile, "But if your unit is in a hurry, you can help urge it so that the waiting time between each certification process is not so long. In this way, maybe a year will be enough."
