When Qin Feng returned to Chengdu, within a few days, the delegation to the UK finally returned.

Tu Lao is face is full of spring breeze, now, it is the height of summer, Chengdu is quite sultry, but Tu Lao's face is full of excitement and joy, after seeing Qin Feng, he immediately shouted to Qin Feng: "Qin Feng, you didn't go, it's a pity, let's finally sign!" ”

From last year to now, Tu Lao has made great efforts, how many business trips, discussions on various issues, disputes between the two sides, and just in April, he was still in pain because he couldn't talk, thinking that it was going to be terminated.

And now, after a huge effort, the first contract for military-industrial cooperation projects with the West after the reform and opening up of the country has finally been signed in the British Ministry of Defense building!

A delegation headed by Vice Minister Duan Zijun, Ye Zhengda, deputy director of the Industrial Affairs Office, Cui Wenbo, director of the Equipment Department of the General Staff Department, Fan Junqiu, director of the Air Force Ordering Department, Xie Ming, director of the 132 factory, vice president of the 10th Academy of the Fourth Aircraft Department, and director of the HNA Scientific Research Department, attended the signing ceremony.

When Tu Lao signed the contract, his hands were trembling.

At the same time, this project also brought great prospects to the 132 plant, and the modification of the J-7 was carried out at the 132 plant.

The contract equips the Air Force with a total of 100 modified J-7 aircraft, codenamed J-7II.A, with 20% of the equipment and spare parts, and the first- and second-line ground equipment is configured according to the three bases according to the opinions of the representatives of the Air Force Scientific Research Department. At the same time, the contract reached the terms of the transfer of the manufacturing license for the production of the imported equipment in China, and the transfer fee was the price of 24 sets of equipment, so the bulk parts of 20 sets of equipment required for the training of the introduction of production lines were added. The design office of the 132 factory led by Tu Lao is responsible for the modification of the aircraft, and the test flight after the equipment is installed is jointly responsible for both parties.

At the same time, what is more exciting is that the introduction of this time, it can be said that it is synchronized with the world, 7 items of imported equipment, in addition to the system synthesis of the Marconi company, its own production of 4, of which the head-up display is a small modification, the air data computer is a major modification, the ranging radar is newly developed, and the radio station is also newly developed.

It can be said that the success of this project is the highest level in the West and the highest level in the United Kingdom, and after such improvements, the combat effectiveness of our own J-7 will reach a higher level.

Qin Feng was also extremely excited in his heart, he had long wanted to fly an airplane with a flat display, especially when operating the cannon, using the flat display for fire control, which was much better than the current means.

"Many projects are newly developed, so the task of Marconi Company is not small, and the task of our factory is not small, Qin Feng, you have to wait, let's talk less about a year before we can start the test flight of the new aircraft."

"Our Comrade Qin Feng, we can still afford to wait, Lao Tu, do you know? After Qin Feng went to Shenyang, Lao Gu had a black face, and he wanted to leave Qin Feng behind, and later, Qin Feng came back secretly, and now, every once in a while, Lao Gu will come to call someone to ask for someone, and also, you will go to a meeting in the future, and when you see Lao Gu, you must go around. The old factory director Sun Lao said with a smile.

Qin Feng's approach moved Tu Lao and others very much, Qin Feng chose to take root in Chengdu and gave up Shenyang, which had better prospects, which was an encouragement and spur to everyone.

"Qin Feng, thank you." Tu Lao said.

Qin Feng didn't feel how great he was, when he was in Shenyang, Qin Feng didn't feel happy, he was still very depressed, like-mindedness is the most important thing, those people came up with the J-8, and they proposed to put a flat display on the J-8, but they were scoffed at, our fighters don't care about aiming, because we will fly closer, our planes are for war, not for enjoyment.

There are so many arguments that I can't communicate, but here, everyone is trying to keep up with the West.

"Old Tu, we don't need to say kind words, in short, it's modified, just let me fly." Qin Feng said.

Qin Feng will always be like this, Tu Lao looked at him and said, "Aren't you afraid that other test pilots will have opinions?" ”

After all, there is a test flight team in Factory 132, Wang Gang has not been transferred yet, he is the team leader of the test flight, he is competitive in everything, how to get along with other people?

Of course, this is also a joke, in fact, since Qin Feng participated in this project, he is the person who is most familiar with this project, and no one has an opinion on him to fly.

"No, we have no opinion." At this moment, someone behind him said that it was Wang Gang who walked in: "Qin Feng's efforts are what we all see, if he doesn't fly, who will fly?" ”

After speaking, Wang Gang pointed to the table next to him, where there was a strange thing.

It looks like a computer monitor, but the graphics on it don't move, and if you look closely, it should be a cardboard box, pasted like a monitor.

Tu Lao walked over slowly, looking at the front of the cardboard box, there was a drawing paper stuffed with a flat pattern clearly drawn on the paper.

"Because we are about to fly a plane with a heads-up display, we must be prepared." Qin Feng explained on the side: "This, it is best to use a computer to simulate, and a heads-up image will appear on the computer screen, but we don't have that resource, so I will use this to train temporarily." ”

For the test flight, Qin Feng has already begun to prepare.

In the past, all domestic fighters were instrumented one by one, and the J-7 was to be equipped with a flat display, how to use this flat display, how to be proficient, are all particular.

It would be best if he could use a computer to simulate it, but in this era, it is impossible for him to mobilize the resources of the computer as a test pilot, let alone the ability, to come up with a simulation system by himself.

Qin Feng thought that his father had bought a black-and-white TV, which could be used to display the picture, but how to make the picture output still didn't work, so Qin Feng could only use the current way to simulate and familiarize himself.

"What is this cardboard box for?" Elder Tu asked.

Qin Feng demonstrated it, only to see him dial a mechanism, and the piece of paper in front of it fell, and then, a piece of paper appeared in the back, and the pictures were all flat display, but the content displayed was different.

"I have seen foreign training courses, and if you want to adapt to the operation of the third-generation aircraft, you must first do a test to judge the situation by looking at the picture, which is called the 'YES/NO' experiment. The pilot presses the YES key and the NO key with his two fingers respectively, and then observes the different pictures displayed on the computer screen, mainly the judgment screen displayed on the head-up display during actual combat, if the pilot judges that the display screen is correct, press YES, if it is wrong, press NO. We are asked to make 100 judgments at a frequency of 0.3 seconds, and we can't be wrong once, so I plan to adapt to it in advance. ”
