"Now, Old Tang should be happy." Tu Lao said on the side: "Minister Wang, aren't you digging my corner?" ”

"There will be no delay, when the Jian-7 CP comes out, Qin Feng will definitely be the first to make his first flight, right?" Brother Wang said to Qin Feng.

Qin Feng nodded, that's nature!

Moreover, I don't have to go to Guizhou too early, and when their plane comes out, it's not too late for me to go over, after all, I am just a temporary guest as their test pilot, and I don't want to follow them to do research together, now, Qin Feng's most important project, the first is Project No. 10, and the second is this Jian-7 CP.

Minister Wang and Tu Lao Qin Feng and others chatted until late at night, and he was also very concerned about the improvement project of Jian-7 this time, after all, this was an opportunity to significantly improve the performance of his own fighter jets.

In addition to the engine, there is also avionics!

"Lao Ba will coordinate avionics and find several advanced radars to equip on this kind of fighter." Tu Lao said: "For us, this is a good opportunity! ”

Minister Wang nodded: "Yes, their next meeting will start soon, let's try to negotiate all this and get all this equipment as soon as possible!" ”

J-8 is still waiting over there, the current J-8 only has planes, and there is no suitable radar yet! Without medium-range interception capabilities, it will never be a qualified fighter that focuses on interception operations.

Sure enough, what Minister Wang said was very good, and soon after returning to Chengdu, good news came that someone from Pakistan had arrived!

"Lieutenant Colonel Mirza?" Seeing the person coming, Qin Feng was overjoyed, he was still an old friend, when he went to Pakistan to confront, this lieutenant colonel was one of the people in charge of the base, Qin Feng and he had met many times, and now, when he saw his old friend again, Qin Feng recognized it at once.

"Qin, having you participate in our project makes us feel much more at ease." Obviously, the other party was also very happy: "This time, our general and the American side have talked about projects such as engines and avionics, so we came over to do a coordination, and at the same time, we have some new opinions on our cooperation projects." ”

Hearing the words of these people, everyone present muttered in their hearts, this project will always have countless requirements, but the aircraft that people want must be improved according to others.

"Okay, we will definitely improve according to your requirements, now, do you say it first, or do we say it first?"

Last time, I only put forward a project plan, but this time, after a few months, the J-7 CP plan has become more and more perfect, and this is the first time that this plan has been completely explained to the other party.

Who says first?

Sit down, a table of people.

Qin Feng participated as a test pilot, and although there were only three people from the Pakistani side, they were definitely experienced, and the leaders of China Aviation Technology were accompanied.

Who says first?

The other side has prepared a perfect plan, how to design the J-7 CP, how to achieve the performance requirements they put forward, and the other party must further put forward some requirements for improvement.

"Let's introduce me first." Lieutenant Colonel Mirza said.

"Okay, let's introduce it first." Tu Lao said, picked up a plexiglass model, and put it on the projector.

This is, of course, the inspiration from the new J bidding last time, so put it on the projector, J-7 CP suddenly appeared on the screen, the three-dimensional sense is perfectly presented, with a unique momentum, suddenly, several Pakistani guests sighed.

I can't see the appearance of the original J-7, it's very beautiful!

On the drawings, no matter how good-looking the painting is, it is difficult for people to have an intuitive impression, the model is different, the model is three-dimensional, even if it is hit on the projector, it will make people look intuitive, this is the charm of the model, even if it is an aircraft designer, when designing an airplane, you must first make a wooden model, just to be able to see more clearly what the aircraft you designed looks like.

"This is our plane." Tu Lao began to introduce, and the results of a few months, Jianqi CP, already seem extremely advanced.

From the nose, it is almost a shrunken J-8, with air intakes on both sides, iconic wings behind the air intakes, and a towering back ridge behind it, although that thing blocks the view, but to store more fuel, it is definitely the best position.

"That's our solution, we're going to add a maneuverable flap to the leading edge of the wing, which will greatly improve the performance at the high angle of attack." Tu Lao began to introduce.

This is the latest consideration plan, the last time I went to the navy to discuss, after which they got this consensus, although it is difficult to process, and it is difficult to choose the servo, but it can significantly improve the maneuverability of the high angle of attack, which must be launched.

"When we improve the nose in this way, the center of gravity of the whole aircraft will also change, so we also intend to do a complete calculation and modify the shape of our wings and modify the position of the center of lift to match it."

If it is just a simple modification, replacing it with such a nose, it will definitely lead to a change in the center of gravity, and the front is heavy, after all, the large nose is stuffed into a large radar, and there will be weight gain.

This is the same as the plan of the J-7 MF in later generations, the belly air intake, the large nose, also led to the weight gain of the nose, and their solution was simpler, directly adding a small canard wing in front to generate lift, rebalancing, at the same time, you can also pull out some vortices.

But now, everyone doesn't think about the three-wing layout, which is more complicated, and it is not as good as it is now.

Of course, the biggest change in this plane is the nose, the air intake on both sides is imported from Shenyang, and the brother units are still more taken care of, Tu Lao only spent 200,000 yuan, so he bought all their materials and came back to study them.

But now, when it comes to specific aspects, the air intakes on both sides are not as flat as J-8, and there are some drums, which are more similar to Qiang-5.

Now, this plan has finally been brought to the customer for the first time, and Tu Lao has introduced the customer in detail, in addition to the technical data of the entire aircraft, it is a requirement.

"Now, if we want to take it a step further, we need more parameters from you." Tu Lao said: "We ask you to provide us with these materials as soon as possible, and now, they are all in the attached documents." ”

This is a long document, including a list of engines, on-board equipment and a list of information, only these data are confirmed, and the next step of design can be carried out, everyone is waiting!

With the exchange with foreign countries, Tu Lao is also becoming more and more proficient, and all aspects of the information are well prepared.
