Liu Yijiu didn't expect that he just reminded that this really became a reality!

This situation occurred when the Republic is developing a weapon system for medium-range air-to-air missiles. This situation will still be encountered here. It seems that if it is impossible to produce advanced opponent's over-visual range missiles without encountering them?

Why is this?

"Mr. Zhu, don't worry, this thrust is completely within the range of the structural strength of the fighter. If this thrust can damage the fuselage, then..." The imitation F-14 had been tested in the air for such a long time, and the maximum take-off weight has not been tested, but the maximum range during the normal take-off weight has been tested, and the maximum speed has also been tested. If there is a problem with the fuselage structure, it will not be able to damage the fighter's structure with just such a little reaction force.

After hearing this, Zhu Houdao felt relieved. Anyway, the missile was just a model and did not have fuel or combat components installed, otherwise they would not dare to stand at such a close distance to observe.

"It will only stop after the power of the booster is used." Ren Xinmin did not expect that such a thing would happen.

This is a shame for them.

He looked at Liu Yijiu with some concern. Seeing the young man's calm face, he seemed to have foreseeed such a problem. He couldn't help but carefully recall the details in the design process.

Especially Liang Sili, who is responsible for the missile control system and the launch control system is also in charge of the work. He is completely unable to figure out where the problem is. The control system of large rockets does not have such a problem, and he ends up fighting on such a small missile.

In just over twenty seconds, the power of the booster completely disappeared, and the missile was still quietly hung on the launcher.

After the stationary period, a group of designers ran under the wings to check the problem closely. Zhu Houdao and others had even asked someone to find the design drawings to check whether there was a mistake in the assembly process, although this had been checked several times after the missile was mounted.

There is no result, and the specific reason can only be re-checked the entire design.

Regarding the design, both Zhuhoudao and Liang Sili felt that their design was fine, so they tried the launch problem of Changkong Lijian-01, and the same was true.

The booster is started, but the booster cannot push the missile out of the launch rail. This is an experiment conducted when there is no negative speed. Once the experiment with negative speed is conducted, it will be even more difficult!

In the end, all the people sat together again for technical discussions and analyzed why such problems arise.

"The processing sizes of all parts are completely qualified, and the tolerances are within the best range, not a quality problem." Zhu Houdao thought it was a quality problem at first, but he did not think that such serious mistakes would occur in the design.

After detailed inspection, even the thread diameter of each screw has been carefully tested, and the results tell them that there is no problem with the accuracy.

With the promotion of the seven special technical agreements formulated by the Ninth Academy from the beginning throughout the country, all military units that currently adopt seven special technical agreements to control production quality and manage production, quality problems have been reduced many times. Those companies with weak execution strength will naturally not be guaranteed.

Those with high precision are simply that the Ninth Hospital conducts production on its own, or that it is a finishing workshop such as Factory 132.

In order to find problems from one's own perspective, Zhuhoudao first looks from the production and manufacturing aspect. If it is just a quality problem, it will be easy to solve.

It has now been confirmed that it is actually due to the design of the launch system.

"Although we have not found where the problem is, the current results and analysis show that this should be the problem in the design. We will find out the problem as soon as possible and improve it!" Du Zhongkun was not unwilling to admit their mistakes.

When he said this, he looked at Liu Yijiu.

Since Liu Yijiu was reminding him, he should definitely know where the problem occurred, but for such a long time, Liu Yijiu did not point out where the problem was as before. This really made him feel a little nervous and he had to find out the problem by himself.

He knew that Liu Yijiu would not interfere in these matters now.

Of course, he knew even more that if he asked Liu Yijiu, Liu Yijiu would say it, but that would be a shameless thing for him.

Everyone knows the magic of Liu Yijiu. It is impossible for this kid to know everything, but their professional technical researchers cannot even solve these professional technical problems!

It's simply embarrassing.

"Let's ask Director Liu. Since he pointed it out, he must know, otherwise we will waste a lot of time!" Liang Sili discussed with Du Zhongkun and others for a long time, checked their design countless times, but could not find the root of the problem.

For them, this is really incomprehensible.

"If you don't ask him, we can't ask him everything!" Du Zhongkun said gritting his teeth.

Liu Yijiu spent most of the days with Simonlov, mainly discussing the new fighter jets that are producing prototypes and are scheduled to take their first flight during the National Day.

"In terms of time, our delay may affect the shooting of targets during the National Day!"

"Let's find the problem first. If we still cannot find the problem within two days, then we will ask him again!" We must fight for this tone!

Zhu Houdao is becoming a little anxious now. Liu Yijiu seems to be able to solve any problem. He found that from the beginning to now, Liu Yijiu has always been calm. He did not take the initiative to discuss problems like before. He actually went to discuss some details and technical issues with Simonolov when time was so tight.

He was very dissatisfied and went to find Liu Yijiu.

Facing Zhu Houdao with an angry face, Liu Yijiu didn't feel embarrassed, "Mr. Zhu, we have to fully trust our technicians. If they can't find the problem, how can I find it?"

"How is that possible!" Zhu Houdao looked disbelief, "Is there something that Mr. Du offended you?"

"Have you ever seen conflicts happening within us?" Liu Yijiu asked with a smile, "I really don't know. Except for the basic technology I got back, I didn't participate in the rest."

Liu Yijiu's words and his expression made the gentle words speechless.

Does he really don't understand?

"Don't worry, they will solve it. It will not affect our target shooting before National Day."

Finally, some technical personnel such as Zhu Houdao also participated in the solution to this problem. After the missile model test, Du Zhongkun and others checked their designs again and again, for 24 hours without any rest.

"There is no problem with the hydraulic system. The stress condition of the launch rail in the working project changes according to the changes in this diagram. Our design is not a problem! There will be no problem with the connection between the tail of the missile and the launch rail..."

"During the work process, the booster generates thrust, overcoming the negative speed and the reaction force brought by the fighter's high-speed flight. Under the push of the booster, the missile moves forward along the launch rail. The device on the launcher hits the sensor in front, and the connection between the launcher and the missile bounces open under the impact force..."

The analysis of a group of technicians found no problems from beginning to end.

"My workers, I think our missiles have not moved at all on the launch rail..." a technician suddenly reminded.

"Not moving? That means there is a problem with the launch rail? Isn't it because there is no problem with the detection accuracy?"

When Zhu Houdao heard this, he frowned immediately.

"No, what if our design idea itself is wrong?" Liang Sili said suddenly.

"Then why are there no problems with our experiments on the ground platform? There are problems at the aircraft hanging point..." This is a problem that Zhu Houdao and others have never thought about. The ground launch platform completely simulates the launch status under the wings of the fighter.

"I think there are some problems with us using the connection pins at the tail..." The technician who asked at the beginning continued, saying that he was not confident, so his tone was very unsure.

Hearing this, Du Zhongkun and others immediately began to verify it.

When the result was obtained, Du Zhongkun asked very seriously at the technician who asked at the beginning, "Xiao Chen, how did you think of this problem?"

"My boss, because I didn't think about other problems. We have tested the reliability of the system before, and the connected pin was designed without considering the need to push too much force to push and move the missile along the launch rail..." The young technician pointed to the design assembly diagram with some embarrassment and explained.

When designing, it is considered that a relatively small force is required to loosen the fixed pin.

However, on fighter jets, the design is strengthened because of the gravity of the missile itself and considering that the missile needs to withstand relatively large negative speeds on fighter jets, avoiding movement...

"It seems that we are really old!" This was not a problem, and they didn't notice it at all.

The excessive design made the Changkong Lijian unable to be unsheathed. No wonder Liu Yijiu was unwilling to remind him.

It is because their thinking has not yet fully adapted to design under higher technical conditions!

"It's solved? Let's conduct the test as soon as possible. I look forward to the performance of our fighter jets and missiles during the target shooting!" Liu Yijiu did not react much after knowing it.

He was relieved that the first batch of college students who graduated after the Republic resumed the college entrance examination have begun to grow.

Compared with the older generation of technical experts, their thinking is more unrestricted.

Liu Yijiu is waiting for the target shooting now.
Chapter completed!
