Chapter 540 AC139 helicopter, the key to entering general aviation!
The other side.
After chatting with Xu Yang that day, Chang Haonan immediately contacted Ding Gaoheng.
Of course, the matter is too big to explain clearly in just a few sentences on the phone.
Therefore, he spent a few more days writing a report on the entire research and development idea for GPS jamming equipment, and then found a time to personally deliver it to the Commission of Science, Technology and Industry for National Defense.
Ding Gaoheng's office is almost more familiar to Chang Haonan than home.
"This...is the plan for GPS jamming equipment that you called me a few days ago to tell me about?"
Ding Gaoheng took the report that seemed to be dozens of pages long When I received it in my hand, I was stunned for a moment.
Although he had seen the other party's amazing ability to sort out ideas before when he read the "Aero Engine Inlet Distortion Test and Evaluation Method" also written by Chang Haonan.
But after all, the material was transferred to the Science and Technology Commission through a third party. In fact, no one knows how long it took Chang Haonan to write it.
So the impact is not intuitive enough.
But this time, Ding Gaoheng clearly understood that this heavy report in his hand was written by Chang Haonan less than a week ago.
“Yes, but this is so thick because it contains a lot of explanations and derivation of algorithms and content related to ideas. Just take a look at the ten or so pages of the final summary.”
Chang Haonan said, taking off his hat and scarf and putting them aside, then sat on the sofa on the side of the office.
Ding Gaoheng, on the other hand, quickly took out his reading glasses from the drawer, put them on, and then opened the report he just got.
"Satellite positioning and satellite guidance have always been a worry for our country."
While scanning the lines of text in front of him, he said with some emotion:
" In August and September of 1995, when the Bosnian War was going on in the Balkan Peninsula, our foreign personnel stationed in Sarajevo saw with their own eyes that the missiles launched by the US military were directed to hit where they were. In two warehouses next to each other, three missiles could be fired at the same time. One of them was hit, and the other was not damaged at all except for some shock waves..."
"I later learned that those were a total of 13 Tomahawk missiles launched by the USS Normandy cruiser, which were also equipped with satellites. The positioning system's cruise missiles were put into actual combat for the first time, which really gave us a long-term perspective..."
"Since then, the PLA has become a leader in combating cruise missiles and preventing precision guidance. Something that units at all levels must practice..."
Ding Gaoheng's attention was gradually attracted by the contents of the report, and he did not continue after saying this.
But what follows is self-explanatory.
Although the "New Three Attacks and Three Defenses" has been officially adopted as a systematic training content since 1995, in the absence of insufficient technical means, the effect that can be achieved by relying solely on subjective initiative is always Relatively limited.
At best, we can only adopt passive response strategies such as decentralized command, decentralized deployment, and enhanced camouflage to minimize losses when attacked.
As for resisting the attack...
There is indeed no such condition.
In fact, after the J-8C fighter jets were officially equipped with naval aviation, the first combat subject practiced by pilots was to use a radar with the ability to look down and shoot downwards combined with semi-active radar-guided missiles to intercept low-altitude cruising aircraft. missile.
It is used to simulate the response strategy when an imaginary enemy uses a submarine to launch a cruise missile attack on our coastal cities.
It is enough to show that the People's Liberation Army is worried about these long-range precision guided weapons at this time.
And if it is possible to interfere with the GPS system on which these weapons rely, even if it is only limited interference, it can greatly reduce the air defense pressure faced by the People's Liberation Army and important coastal targets.
"This equipment can also be integrated and installed on aircraft or vehicles?"
After seeing the scenario for the GPS jammer combat mode in the middle, Ding Gaoheng's eyes flashed.
“In order to ensure the confidence of the interference signal, this device has strict requirements on the emission angle. In other words, the scope of action is close to a cylinder, with a small area but a height close to infinite. In order to ensure the interference effect , it is best to be relatively close to the target, or even implement jamming in advance.”
“As mentioned later, for example, for targets such as cruise missiles, the best way is to use aircraft while the missile is in flight. Carry out accompanying interference and input wrong height and position information to the target, inducing the missile to fall to the ground or into the sea early."
Ding Gaoheng nodded repeatedly after saying this.
"So, if installed on a vehicle, it can provide accompanying cover for high-value targets such as battlefields and command posts. It is equivalent to supporting another barrier behind the original last line of defense of small-caliber anti-aircraft guns."
"In terms of the current strength comparison, reducing the air defense pressure is to save the lives of the soldiers!"
The further back the report went, the more excited the expression on Ding Gaoheng's face became. , and even the movement of flipping through the pages became much more brisk. ……
“In other words, what you need now is a military GPS positioning receiver?”
After a long time, Ding Gaoheng put down the report without finishing.
It seemed like he wanted to watch it again from the beginning.
But I held back.
“Not one.”
Chang Haonan shook his head:
"The jammer needs to receive and analyze the positioning signal sent by the GPS constellation, and then it can be translated through the algorithm mentioned in the report."
"Considering that we do not have the ability to reproduce the original U.S. military equipment for the time being, we can only It can be treated as a black box, so... every jammer should need a military GPS positioning receiver."
Ding Gaoheng's original expression of joy froze on his face——< br>
It’s hard enough to get one. Do you want to purchase it directly from the US military?
“It doesn’t have to be a complete positioning terminal, such as weapons and equipment, or even satellite navigation modules on ammunition. In short, as long as there is a chip that can process the signal and be removed.”
Chang Haonan explained it in more detail.
But the problem facing Ding Gaoheng did not become much easier.
"This kind of thing is definitely not something that our Science and Technology Committee can handle. I'll report it to the relevant departments first and let the relevant departments pay attention."
Ding Gaoheng scratched his head and sighed helplessly. Tone:
"Fortunately, your algorithm should be a unique skill. Americans should not pay too much attention to signal receiving terminals. Although it is difficult, it is not impossible. But the output may be subject to some restrictions. …”
When he just read the report, his first thought was to equip every regiment and unit above the regiment in the army with a set -
If there really was a fight, he would make the imaginary enemy look like us. level of skill and defeat them through rich experience!
But now it seems a bit whimsical.
Of course, something is better than nothing.
Even if there are only a few devices, if they can appear in key locations, they can still play unexpected roles.
So Ding Gaoheng quickly regained his energy.
He put the information in front of him into the drawer, and then took out a folder from the filing cabinet at the back.
"Xiao Chang, there is one more thing."
"AgustaCorp, which has cooperated with us on the MA-60 project before, hopes to expand the scope of cooperation and work with Bing City Aircraft Industry Group jointly developed a new helicopter.”
“I communicated with Bingfei and they said that the new helicopter currently under development is part of the solution provided by your Torch Group. This cooperation requires you to nod and agree to join the project.”
Chang Haonan stood up and took the folder with some surprise.
For the Zhi-9 Improved Project, he only pointed out the direction at the beginning, and did not interfere too much later. It all relied on Professor Liu Hongbo’s own performance.
Now it seems that it should be a good performance for a high-end helicopter giant like Agusta to actively seek cooperation...
"AC139 helicopter..."
< br>The Italians have not only decided on the name, but have even made renderings of the preliminary plan.
"A is Agusta, C is our China Aviation Industry Corporation, CAAC, AC139, which is jointly developed by Italy and China."
Ding Gaoheng explained beside him:
"The plan is 15-18 seats, 6-7 tons, mainly for high-end markets such as VIP transportation, medical rescue, search and rescue. If we agree, the cooperation method will be based on the MA-60, and two final assembly lines will be built in China and Italy respectively. Connect with the Asian and European and American markets. ”
“In addition, if the technology meets the standards, the Italian side can ensure that the proportion of Chinese suppliers will not be less than 30%.”
“You. What does it mean? ”
