Chapter 707: Got it right, add ten points

"Zhenhua, why did you mention the "Lavi" project to them?" In a corner of a small cafe that was randomly selected, Zhan Nuozhu asked Tan Zhenhua in a low voice in a voice that only two people could hear: "And from both of you Judging from the reaction, this "Lavi" project should have a fairly high level of security. If you do this, will it cause unnecessary trouble?"
Unsurprisingly, when Tan Zhenhua broke the "Lavi" project and declared without embarrassment that he wanted to acquire all the technical achievements of the plan, the talks of the day could no longer go on, David Yukins, Lu Lia Buxbaum and Heinrich Neumann said that they had a big deal, and they had to rush away after discussing and deciding to reply within the company. Werner Michael Blumen Thrall took a deep look at Tan Zhenhua and left afterwards. He said that his mission has been completed. In the next few days, he will take this rare opportunity to meet several old friends who live in Tel Aviv. Chat, reminisce about the past rosy years.
However, Zhan Nuozhu, who had not said a word during the entire meeting, came to the Middle East with a rare occasion. He wanted to wander around and appreciate the awkward excuses of the exotic atmosphere. He pulled Tan Zhenhua out of the door and declined the host’s intention to send someone to accompany him.
Tan Zhenhua, who was half pushing and halfway through, went to the street with the lame man, and after a casual stroll, he randomly found a small cafe on the side of the street and sat down, started a conversation, and sat in the position closest to them. They are Zhang Xiaohua and his wife who seem to be casual, but are actually full of vigilance.
In fact, both of them are well aware of the purpose of doing this. Mossad is the fourth-ranked intelligence organization of Blue Star. Its ability is beyond doubt. This is the nest of MSD. No one knows whether the Isaans will What mess of gadgets are installed in the hotel where they are staying, and only in such a randomly selected place can this private conversation be conducted relatively safely.
The matter is of great importance. Of course, Tan Zhenhua needs to explain clearly to Zhan Nuozhu the purpose of doing this: "Brother Zhan, I don’t want to hide it from you anymore. I actually have three goals for this trip to Isaac. In order to achieve these goals, I must adopt some strategies."
Zhan Nuozhu sank for a while and said: "Your first goal is obviously to complete the procurement of 12 "Sea Harrier" fighters supporting fire control radars. The second goal is also that we have discussed in advance. If possible, get I understand the full set of technical documents and authorized production licenses of EL/M-2021B, but what is the third goal you mentioned? Is it the full set of technical documents for the acquisition of IAI’s "Lavi" project you just mentioned? This I'm afraid the difficulty is not small? Look at the two faces when you raised this matter just now."
Tan Zhenhua smiled and shook his head and said, "No, Brother Zhan, this is not a difficult problem, but almost impossible."
Zhan Nuozhu said in amazement: "Impossible? What are you doing so lively about impossible things? Do you entertain them?"
Tan Zhenhua said: "When I was in London, I exchanged views with Chief Chen Yijian. The development of the "Flying Leopard" fighter is currently progressing quite well. At present, the aerodynamic shape has been basically determined, and the production of all-metal prototypes has begun, but they also touched There are some technical issues, the two most important of which are flight control and data transmission bus."
Looking at Zhan Nuozhu’s unfamiliar expression, Tan Zhenhua had to explain:
Our Huaxia fighters basically developed from the Soviet Russian system. From the J-5 to the current J-8, including the strong 5 and 6 "Flying Leopard" can be said to be the first type of self-developed fighter in the true sense. Since it is self-developed, there are many technical difficulties that need to be broken through, such as this fly-by-wire flight control system and data transmission bus."
"Couldn't it be based on the system development of the original fighter? Chief Chen and the others have done the H6. They can do it with such a large aircraft, so it can be done with this small plane, right?" Zhan Nuozhu asked Tao.
"That's not the same." Tan Zhenhua replied: "Take flight control as an example. All the aircraft we have worked on before China use traditional mechanical-hydraulic flight control systems. Such systems need to be connected by mechanical circuits. The cockpit and hydraulic circuit, while the mechanical system consists of a series of connecting rods, nooses, pulleys and even hinges. The hydraulic circuit includes hydraulic pumps, hydraulic pipes, hydraulic valves and various actuators. The pilot's manipulation needs to pass mechanical The circuit is transmitted to the corresponding servo valve in the hydraulic circuit, and then the hydraulic pump drives the actuator to control the various control surfaces of the aircraft. In this system, the pilot must concentrate a lot of energy to control the aircraft, and even must pay a lot of physical energy for this. Brother Zhan, you can also fly planes, don't you think?"
Zhan Nuozhu thought about it and nodded in agreement: "You are right, so it is very difficult to train a qualified pilot, and the physical fitness requirements of the pilot are also very high."
"No matter how good a person is, his energy and physical strength are actually limited. When he concentrates on flying an airplane, he will inevitably ignore some other things. But nowadays airplanes, especially fighter jets, have increased in performance. Its flight envelope is getting wider and wider, its tactical actions are getting more and more complex, and its combat methods have also evolved from the simplest visual discovery, and cannon strikes have developed into the need to operate a complete set of increasingly complex weapon systems. Radar, sensors, and communication equipment all require pilots to devote more and more energy to respond. Under this trend, traditional flight control systems are obviously no longer able to meet the needs."
"and so?"
"That's why the telex flight control, which is currently popular internationally, appeared."
"Like the one you use on your 4-rotor drone?"
"Compared with the fly-by-wire control system used on manned fighters, mine is really a toy level. After all, the system does not have to consider safety issues." Tan Zhenhua replied: "Because fly-by-wire control also has its inherent flaws, mechanical— —Although hydraulic systems are heavy and have poor maintenance performance, their failures are generally linear. There is a process, relatively speaking, the safety redundancy is large and there is sufficient early warning time; but the failure of electronic devices is often sudden. And once it fails, it often causes the entire system to collapse. Therefore, it is really not a simple matter to get the fly-by-wire flight control system."
"Then how is the safety of this fly-by-wire flight control solved? This is an airplane. It doesn't work if there is a little problem, but it will kill people."
"The current solution is to add redundancy and backup." Tan Zhenhua replied: "Simply put, there are two or more independent control systems to execute the same operating instructions, when one or even two of the channels are damaged. The aircraft will still not lose control. If it is still not enough, you can retain a mechanical hydraulic system. This system only needs to ensure the aircraft’s most basic flight capability, so the design can be relatively simple."
Zhan Nuozhu frowned and thought about it, and then showed his face: "I see, you said with a big fanfare that you want the full set of scientific research results of "Lavi". In fact, it is just a big banner. In fact, the real goal is this "Flying by Telegraph". Control system "right?"
Tan Zhenhua stretched out his thumb to give Zhannuo Zhubi a big "like", and then smiled: "That's right, plus 10 points. "Fly-by-wire flight control system" is my first goal. Of course, this system must Only with the blessing of the data bus can it play a full role, so that is also the goal. Of course, if they are really willing to sell the full set of materials and the price is right, I don't mind buying them all."
