Chapter 616 Zhang Qihang's Ambition
Zhang Qihang shook his head and said, "This leader, I'm afraid it won't work."

"No? Why?"

"Leader, it's like this. Our engine's design take-off altitude is 5000 meters, the critical supercharging altitude is 7800 meters, and the maximum operating altitude can even reach and exceed 10000 meters," Zhang Qihang explained: "But due to the overall cost Considering that our helicopter is designed to fly at a maximum altitude of only 3000 meters, if it is a specially designed plateau helicopter, there is no problem with this engine, but our helicopter..."

Understood.

What's not clear about this?
The design of this engine has no problem with plateau performance, but the problem is that the performance of this helicopter of Huateng Group cannot reach it. Of course, if this engine is installed on a plateau special model helicopter specially developed for plateau areas, then No problem.

After thinking about this point, everyone felt a little regretful, but the regret was regrettable, and the leaders didn’t think there was anything wrong with it: you’re probably out of your mind to expect a local state-owned enterprise to come up with a plateau rotorcraft?

Vice President Miao nodded again and again, obviously very satisfied with this engine of Huateng Group, but then he asked curiously again: "Xiao Zhang, why did you set such a high technical index for this engine? What is it?"

Huh?
It really is……

It’s fine if Vice President Miao doesn’t say anything, but now after listening to Vice President Miao’s words, all the leaders reacted immediately: Yes, for a model with a maximum flight altitude of only 3000 meters and initially positioned as an ultra-light agricultural plant protection As far as the supporting power of the helicopter is concerned, the starting altitude of 5000 meters, the critical boost altitude of 7800 meters, and the maximum flight altitude of more than 10000 meters are really a waste. How much energy is required to achieve such a technical index? ?
There is absolutely no need for this.

So the question is, what is the reason why Huateng Industrial Group set the technical indicators of this engine at such a height that is almost completely meaningless?
"This..." Zhang Qihang hesitated for a moment, scratched his head, and said with some embarrassment: "There is actually a little bit of our thinking in it."

Vice President Miao encouraged: "What do you think? Tell me."

Now that the biggest leader present has already talked about this, Zhang Qihang no longer hides it, but he did not immediately answer Vice President Miao's question, but instead asked: "President Miao, do you know Are the Gnat-750 and tier-2 UAVs of General Atomics of the United States?"

"Gnat-750 and tier-2 drones?" Vice President Miao was a little surprised, even more shocked: "Do you know these two drones? How much do you know?"

What this means is that Vice President Miao knows about these two drones.

"Yes," Zhang Qihang nodded and said, "The Gnat-750 UAV is a long-endurance UAV developed by Millikin Leading Systems on the basis of the Gnat-400 for battlefield reconnaissance and surveillance. In 1990, Leading Systems was acquired by General Atomics. Last year, the Gnat-750 was deployed to Albania by the US Central Intelligence Agency to detect combat situations in southern Yugoslavia. Escort of military operations and military equipment;
The maximum take-off weight of the Gnat-750 UAV is nearly 600 kg. It is equipped with a military-standard rotax 912 engine produced by ROTAX. Patrol outside the area for 2000 hours before returning. "

"Wow……"

When everyone heard this, they were suddenly amazed.

An unmanned aircraft, after traveling 2000 kilometers, can still fly in this area for another 12 hours, and then return to the base by itself. The technical content of this is so high that it really makes people feel scalp Numb: America is really amazing.

Regarding Zhang Qihang's answer, Vice President Miao was also very surprised: "Comrade Xiao Zhang has a very detailed understanding of the situation of the Gnat-750, so how about you talk about the situation of the tier-2 drone?"

"Okay," Zhang Qihang nodded, and continued: "The tier-2 drone is developed on the basis of the Gnat-750, so it's okay to say that the tier-2 drone is an enlarged version of the Gnat-750 Can't.

The reason why the Mi Army asked General Atomics to develop a tier-2 drone is because the Mi Army believes that the performance of the Gnat-750 is still limited and cannot fully meet its own requirements.

Compared with the Gnat-750, the tier-2 UAV is not only larger, but also more advanced in performance and equipment. The maximum battery life exceeds 40 hours. It is equipped with photoelectric/infrared reconnaissance equipment and Westinghouse's all-weather synthesis Aperture radar, intelligence information equipment, laser designator, imaging transmission and video distribution system, and data link system are very powerful. They can not only be used for reconnaissance and surveillance in small areas or valley areas, but also provide detailed battlefield intelligence for special forces. , and can even transmit full-rate video directly from the front line to the rear command and control center, allowing the rear command center to grasp the situation on the front battlefield in real time and make the most appropriate judgments and decisions..."

"..."

Listening to Zhang Qihang's eloquent talk, everyone's eyes were straightened, and at the same time, deep sorrow and powerlessness filled their hearts: a drone, which traveled thousands or even 2000 kilometers to the battlefield, directly reported the situation on the scene with The video is transmitted back to the command center of the base camp thousands of kilometers behind through the data link. What is this?This is clairvoyance, this is the real "clairvoyance"!
The commander in the command center can make the most appropriate decisions and deployments based on the situation ahead. What is this called?This is called Palm View!

If the way of war develops to this extent, then what a fart, this means that the battlefield is almost one-way transparent for the Mi Army. The Mi Army can see us, but we cannot see the Mi Army. What does the Mi Army think? You can fight as you like, and we can only be beaten passively...

Realizing this, the atmosphere at the scene visibly weakened.

Zhang Qihang did not intend to stop, and continued on his own: "In July last year, tier-7 made its first maiden flight. It is said that the Mi Army is very satisfied with the performance of this drone and has sent Funding for Phase II was advanced to General Atomics.

According to the situation announced by General Atomics, if all goes well, it is expected that they will complete the technical verification of tier-2 drones next summer. It is expected that by 1997, tier-2 drones will be officially purchased by the military. .

In addition, General Atomics has also announced a series of ambitious plans, such as the development of a multi-purpose version of tier-2, which can carry at least two "Hellfire" missiles, so that tier-2 drones have the ability to "find and destroy" . "

After Tier-2 was officially purchased by the US military, it obtained the official military number: RQ/MQ-1, where RQ is the version of reconnaissance, surveillance and target indication, while MQ is the version of multi-functional reconnaissance and combat, which can be carried Two Hellfire missiles attack ground targets.

After that, the American Atomic Corporation launched a further improved model on the basis of MQ-1: MQ-1B, this version is the later famous MQ-9 "Reaper" UAV-in fact, strictly speaking, MQ- 9 The direct relationship between the "Reaper" and the MQ-1 "Predator" is no longer significant. The maximum take-off weight of the MQ-1 "Predator" drone is only a little over 1000 kilograms, while the MQ-9 "Reaper" is unmanned. The maximum take-off weight of the aircraft exceeds 4760 kg, and its size is more than 4.5 times that of the "Predator". The relationship between the two is more in the same line in the technical field.

But there is no need to say these words.

But after Zhang Qihang's words, the atmosphere at the scene almost fell into dead silence: equip the drone with missiles, so that the drone has the ability to "discover and destroy"?

Nima!

What about future wars?
Vice President Miao also felt the dead silence at the scene, he pursed his lips, and asked Zhang Qihang: "I'm a little curious, what does these things have to do with the engine that Xiao Zhang and you guys built? Could it be that you are still planning to Can't make a drone?"

Ok?
Vice President Miao's words made the other comrades at the scene couldn't help raising their heads: Could it be...

Zhang Qihang smiled a little shyly: "This... how should I put it, this is actually part of my bet, can you say it?"

"Well," Vice President Miao said with a smile, "What can't be said? To be honest, I'm also quite curious."

Zhang Qihang did not answer this question right away, but said, "Dean Miao, you know that I am currently a Ph.D candidate at Harbin Institute of Technology..."

"Well, I know," Vice President Miao nodded and said, "I had a meal with Dean Wu of your Astronautics Institute some time ago, and Old Wu mentioned you to me," said Vice President Miao. The dean said with a smile: "Your Vice-President Wu admires you very much, and you are always full of praise."

"Principal Wu didn't think I would embarrass the school," Zhang Qihang said politely, knowing that it was not easy to sell, he continued: "We have a lot of exchanges between Harbin Institute of Technology and Western Institute of Technology. We decided to develop our own piston aeroengine. I knew that there was a UAV project at Xigong University. It is said that this UAV project is somewhat similar to the Gnat-750 of the American Atomic Corporation...Of course, I am not very clear about the specifics of this project. The technical level of the man-machine seems to be fully aligned with the Gnat-750.

When our teacher told me about this project, he said that the country attaches great importance to the development of unmanned aerial vehicles, especially large unmanned aerial vehicles. If this project can be successful, the Western Polytechnic University is going to learn the development route of the American Atomic Corporation. On the basis of this drone, make a drone similar to tier-2.

I just thought about it, our country has always attached great importance to the development of drone technology, but the field of low-power piston aeroengines mounted on drones has always been a shortcoming. If our country decides to vigorously develop drones, it will not Maybe all of them are imported engines? "
