"It's not a problem of design, what is the problem? Ordinary 107 rocket artillery can't have such a big deviation......"

Song Bin, deputy director of the Military Representative Office in charge of rocket artillery-related technology, sighed.

The actual situation is too different from what Liu Yue said.

Even if it deviates to 60/70 meters, they will not be so disappointed.

Those who are engaged in scientific research are most afraid of running trains.

In particular, in the field of national defense science and technology, it must be even more rigorous.

If the scientific research personnel are not rigorous, the lives of the front-line commanders and fighters will be in danger.

Liu Yue gave them a lot of hope when he introduced the project before, and now they are disappointed.

The people from the Military Representative Office turned around directly and prepared to leave, and they didn't plan to stay any longer.

"Director Feng, wait a minute, it's not a problem of design, it's a problem of aiming......"

Liu Yue saw that Feng Baoguo and other military representatives didn't even say a word, so he turned around and prepared to leave, and couldn't help but be anxious.

"There is no problem with aiming! I have checked it myself. Moreover, all the staff members of the test launch were originally the technical backbone of the rocket artillery unit......"

Seeing that Liu Yue said that they had a problem with aiming, Xie Jun was suddenly unhappy.

If there is a problem with your own product, blame the staff at the test site.

Missed this pot, and the test firing range was not backed.

"Chief Xie, I'm not saying that you have a technical problem. Liu Yue knew why Xie Jun reacted so much, people from the army can make people doubt everything else, and they will never allow others to doubt their skills.

Just like the top skilled workers in the workshop.

"Then you say it's a matter of aiming?" Xie Jun's face was not good-looking.

"Chief Xie, you haven't test-fired this kind of single rocket launcher, so it's normal that you can't aim. Li Hong fanned the flames next to him.

It sounds true, but it feels very bad.

"Nonsense, no matter how you don't aim, it's impossible that we won't after he says it!" Xie Jun's fire rose in a flash.

It's clear that they are doubting their business capabilities.

The test site is not only missiles, but also rocket artillery, which are all retired from rocket artillery units, and they are also the backbone. Even without sighting devices, rocket artillery can be fired very accurately.

As long as the design accuracy is okay, they can achieve the highest precision.

Otherwise, it would not have been possible for them to be assigned to the reserve base of aerospace in Dabashan after the troops were discharged, which is an affirmation of their professional ability.

For so many years, nothing like this has ever happened.

Rocket artillery and missiles, they will definitely not exceed the range of theoretical accuracy.

If it can't be reached, it means that the problem is in the design.

Xie Jun has full confidence not only in himself, but also in his test firing personnel.

Two rockets in a row, both deflected, the most recent one deviated by 200 meters, which is to blame for not aiming.

This is a disgrace to the troops.

What's more, in front of the senior leaders of the base and the responsible persons of the military representatives.

How can Xie Jun follow?

"Is it really a matter of aiming?" Song Bin turned around and asked Liu Yue with a frown.

Feng Baoguo, who left, and other military representatives also stopped, and even Lin Qiyang and others looked at Liu Yue.

"Yes, I forgot before, the design of the tail of the rocket has been changed a bit, and during the flight, a slow spin will be carried out to improve the progress and reduce ......the production cost," Liu Yue nodded and said seriously.

Now, if not reversed, the situation is no longer a matter of his personal future.

Because of his reasons, Factory 2186 will definitely become the first batch of military industrial enterprises to go bankrupt and go bankrupt.

Liu Yue couldn't let that happen.

Originally, he didn't plan to talk about the slow spin of the tail flame.

For Liu Yue, technology is not complicated, or even very simple, but for this era, it is complicated.

As long as you have such technology, long-range rocket artillery is not a dream at all.

In order to improve the firing accuracy of long-range rocket artillery, it is either to use low-speed spin of tail flame and other means, or to develop in the direction of guided rocket artillery.

For this technology, there have been countless domestic investments and decades of research.

"Really?"

Song Bin asked Liu Yue excitedly.

He is an expert in rocket artillery, so he naturally knows the role of this technology.

"What's going on?" Feng Baoguo felt that it was a complete waste of time now, and Liu Yue gave him a really bad impression, "Let's wait until they solve the accuracy problem." ”

"Director Feng, tail flame spin technology, this is a technical field that we have just begun to study in China, and its purpose is to improve the accuracy of long-range rocket artillery and reduce costs...... "Song Bin made an introduction to rocket spin technology.

Most of those present were experts and naturally knew what that meant.

Zheng Jianguo and others had never even heard of such a technology.

A few people in Factory 2109 were silent.

They wanted to continue to fan the flames, thinking about Liu Yue's origins, but finally gave up.

"Really?"

Feng Baoguo looked at Liu Yue and didn't believe it at all.

It's big, running trains with a mouth, and doing things is not reliable at all.

Several leaders of the headquarters of the base have also remained silent.

They had heard of the tail flame slow spin technology, but because the base had little technical reserves and little experience in rocket artillery, they did not set up a special project to study it.

Although aerospace manufactures rocket artillery, they prefer precision-guided missiles of various ranges used to deliver couriers rather than heavy artillery.

That thing is used to kill the enemy's head thousands of miles away, an absolute weapon.

The rocket launcher thing is too rude after all.

"Chief, that's true. The purpose of the drag ring at the tail of these rockets is also to keep the rockets stable when they rotate during flight......" Liu Yue explained in detail.

The increase in the drag ring at the tail of the rocket is indeed to stabilize the attitude of the rocket during flight, so as to improve the shooting accuracy.

"From the very beginning of the development of cannons, after the improvement of processing technology, rifled guns were used, and these rifling wires engraved on the inside of the barrel were used in order to give the shell the ability to rotate, so as to improve accuracy and increase the effective range...... The initial velocity of the rocket is very slow, and it is not possible to add rifling in the launch tube, so the solution can only be found in the rocket itself......"

Liu Yue saw that the military deputies were willing to listen, and hurriedly said this.

At present, there is still only the production and manufacturing technology of rifled guns in China, and the technical difficulty of smoothbore guns is too high and has not been solved.

The truth that Liu Yue said was originally simple, and no one could not understand it.

Originally, he was extremely unhappy with Liu Yue's words, but after listening to Liu Yue's explanation, Xie Jun instantly figured out what the problem was, "Comrade Liu Yue, do you mean that there was a problem with our correction at the time of launch?"

Ordinary rocket artillery needs to correct the trajectory according to the attitude change of the rocket during flight.

It is very simple, determine the target, launch position, and then according to the elevation angle of the rocket tube, according to the theoretical parabola to test firing, after the test firing, according to the landing point calculation, further correction of the trajectory.

Not much different from the principle of a cannon sight.

The 107 rocket is bare, has no tail and no guidance, and cannot be corrected during the flight, so it can only be supplemented a little in advance according to experience to improve accuracy.

As a result, something went wrong here.

"Yes, Mr. Xie, it's my fault. If I had thought about this before, I wouldn't have had such a problem. Liu Yue sighed.

Song Bin didn't care about Feng Baoguo's impatience, and said excitedly, "Correct it immediately and continue the test launch!"

If this technology really exists, what changes will this bring to the development of the rocket artillery unit of the entire army!
