Chapter 763: Three-year agreement

"Is the detection range of 40 kilometers okay?" This time it was Ben Fang's turn to wonder.
"40 kilometers is already very good, old Ben, don't you know that we are now installing the 204 for testing. The technical indicator proposed that year was "double three plus 100", which means that it is required to detect 100 at a speed of three Mach at an altitude of 30,000 meters. A goal that is kilometers away, guess what?"
Ben Fang ignored Song Wenhua's rhetorical question. Instead, he frowned and calculated for a while: "A 270-diameter antenna, this indicator...what nonsense?"
"Hehe, Lao Ben, you are an expert, you know this is not reliable when you hear it, but the 3607 that year was just slapped on the chest. Although this can’t be completely blamed on them, everyone knows the environment at that time, but they learned from The project was established in 1964 and has been tossing until now. This year I finally said that it was finished. We used it for us and Shengfei to test on the machine. We installed it and flew a few laps for a test. Hehe, the maximum distance of 20 kilometers is out of reach, and it is malfunctioning. There are a lot of problems, false alarms and missed alarms are commonplace, and they are useless at all. You talk, you talk, you have come up with such a thing in nearly 20 years!"
When Song Wenhua said these words, he was obviously full of resentment. Tan Zhenhua was amused but he didn't dare to be happy, and he was holding back extremely hard.
As a previous radar expert, he certainly knows this history.
3607, the full name of China Aviation Industry Ministry Airborne Radar Research Institute, originally located in Neijiang City, Sichuan Province, and later moved to Wuxi City, Jiangnan Province. It and its difficult brother 3780 Factory are the only seedlings engaged in radar in the Ministry of Aviation Industry. One is responsible for research and development. Responsible for production, the relationship is similar to that of Chen Yijian's Xijing 3603 and Xifei Plant. The radar on China's previous fighter planes all pointed to his family.
Speaking of it, the technical strength of this unit is still a little bit. Starting from imitating the СРД-1/1M radar rangefinder introduced with the night models of Soviet MiG-17 and MiG-19 fighters, they started It has been specializing in airborne radar technology, and there are several models of troops installed, such as the SL-3 222 radar rangefinder currently installed on the "J-7".
Unfortunately, with their current level, they can only do simple radar rangefinders.
The relatively closed management system of the Third Ministry of Machinery Industry has determined that they are reluctant to enter other systems from top to bottom to grab their jobs.
Just kidding, I don’t have enough to eat!
Had it not been for Tan Zhenhua to use his trip to Xijing last year to invest heavily in the research and development of the "Flying Leopard" fighter, and then said that Chen Yijian went to Ningdu to visit Benfang, I am afraid that no one in the third machine department would know of a certain former subordinate of the electronics department. This unit is also eyeing the airborne radar cake, and has been sneaking into pre-research for years.
Ben Fang is a kind person, and he has not fallen into the habit of falling into trouble. After listening to Song Wenhua’s complaints, he explained to his future competitors: "Lao Song, this can’t be completely blamed on the 3607. In fact, the pre-research on the airborne radar we did I encountered a lot of difficulties. At the beginning, I didn't even know where the direction was. That is to say, it has been opened up in the past few years, and we have access to some Western materials and advanced components, and we have slowly found a way.
Song Wenhua said: "Old Ben, don't speak for others. I have been tossed by them all these years. Although Song Wenhua is not a radar, I have been an aircraft chief for so many years, and I have dealt with radar. There are also many experts. From London to Tel Aviv, I have been working with you for so long. I am convinced of your old ben’s level. Let’s not gossip about it. You can’t do it with me? You want to do it, I am today. Just treat it as 3611's home, now let's make this decision."
Customers have placed orders, but suppliers are still hesitating: "Lao Song, is there one more thing I just said that you haven’t noticed? If you want to put this radar in your "J-7", it may be less. functional."
"What features will be missing?"
Ben Fang thought for a while and said: "The main reason is that the ground function is likely to be missing. The size is too small and the power is not enough. It is too difficult to achieve the full waveform. Lao Song, you also know that our current China What is the level of the components? I see ELTA radar. All the components except the high-power grid-controlled traveling wave tube are all solid-state and many large-scale integrated circuits are used. This is difficult for us to achieve in the short term. , Unless a large number of Western electronic components are used-which requires them to sell to us."
Tan Zhenhua interrupted: "I don't think Mr. Ben needs to worry too much about this issue for the time being. They should be willing to sell a batch of components. After all, this is also a business, and we can also add this to the contract being drafted. Go. So we can use the components provided by ELTA to get the modified prototype first, and hand it over to Mr. Song to do the test on the machine. If it can meet the requirements, we will mass produce it. As for the components, there are also two Walking on legs, on the one hand, continue to introduce them while taking advantage of the good relationship with ELTA. On the other hand, it also urges domestic component factories to step up their imitation research."
Song Wenhua rarely agreed with Tan Zhenhua once: "Zhenhua's idea is good. If this is the case, can you keep as many functions as possible? It doesn't matter if the performance is slightly worse."
Ben Fang thought about it again for a while before he said: "I will try my best. Lao Song, I can't guarantee you 100% now, because to be honest, I still haven't figured out a few key points about this radar, and as long as there is one place I haven't done. I understand that it is difficult to change it. After all, our contract with ELTA is only initialed, and the money has not been paid yet. It is normal for them to keep a little bit of joints to hold us."
Song Wenhua immediately turned to Tan Zhenhua and said, "Did you hear that kid? Your teacher Ben wants you to pay quickly!"
Tan Zhenhua hurriedly raised his hand and surrendered: "Pay, pay immediately, pay as soon as the contract is signed, and I won't delay a second."
Ben Fang smiled and said: "In fact, you don't need to be so eager. Lao Song, you are also engaged in scientific research. You should know that even if you get a full set of technologies and drawings, it will take a lot of time to fully understand this thing."
Song Wenhua sighed and said, "It can be as early as one day earlier, hey, by the way, Lao Ben, do you think, if you are in charge of this radar, how long will the entire development time take?"
Ben Fang calculated for a while before replied: "First of all, I need to thoroughly understand this prototype, and then make improvements on this basis. In fact, it is a trivial matter to change the antenna size or increase or decrease the function... For three years, I think so. It takes three years."
Song Wenhua was obviously not satisfied with this time, but when he remembered that the unit in this system hadn't made a decent gadget for nearly two decades, he felt that the three years that Ben Fang had promised was already Very, very efficient.
"Three years is three years," he gritted his teeth, stretched out his right palm and gave a light blow to Ben: "Old Ben, please!"
