Super military empire

(Greatly add 5/5 for seafox_wang)

After working on this stall, Liu Yijiu returned to the bus again, and he even had no time for the progress of the twenty-five luck.

Nothing else, something happened to the Dabashan base!

For the first time in so many years, the Ninth Academy has encountered such a thing-when the new surface-to-surface missile designed by the Soviet Union SS-23 spider for the Blue Army missile force was tested at the Dabashan Missile Proving Ground, Only 8 seconds into the sky, an explosion occurred in the volley!

Fortunately, there were no major casualties.

However, Liang Sili and chief designer Du Zhongkun, who were responsible for the design of the tactical missile control system with a range of about 600 kilometers, were injured.

Liu Yijiu hurried back to the Dabashan base. The technical team on the aerospace side needed their financial support to build the Dongfeng-6 with a range of 19,000 kilometers and the Dongfeng-7 with a range of 15,000 kilometers. After completing the work on medium-range air-to-air missiles, the Institute did not return to the Ministry of Aerospace Industry under the pretext of continuing to improve.

With these experts, the Ninth Institute has become even more powerful in this area.

At the same time, the continuous improvement of the 336 rocket launcher, and at the same time, the 8208 surface-to-surface tactical missile with a range of 250 kilometers, which is transformed from the Hongqi-2 air defense missile, is progressing smoothly. The Ninth Academy has better research performance and longer range. The basis for tactical missiles with higher strike accuracy.

The Soviet Union’s SS-23 is a missile that can fight both nuclear war and conventional warfare, especially to improve the artillery’s ability to attack deep targets in conventional warfare. The Blue Army is currently only equipped with 8208 missiles with a range of 250 kilometers. There are longer-range missiles with a range of 500 to 600 kilometers.

Du Zhongkun and others have been working on it for a long time. With the addition of aerospace, the progress will naturally be fast.

Liu Yijiu no longer stared at these things in person.

But I didn't expect that such a problem would occur in the first test.This has never been encountered before.

The first thing Liu Yijiu did when he returned to the base was to visit the two technical experts who were injured in the base hospital.

But I didn't expect to see people at all.

Only a few staff who were also at the launch site were still inspecting, and no one was seriously injured.

"They just made a simple explosion and left forcibly. They didn't do a comprehensive inspection..." Zhao Min shook his head when asked by Liu Yijiu, his face was full of helplessness.

After learning how many people had arrived at the test site, Liu Yijiu directly asked Chen Dashan to mobilize a helicopter to send himself to the missile test site. There are now a large number of technicians gathered there. The launch site is messy, but they are not cleaned up. Many are dressed in white. Researchers in the lab coat are looking for various fragments inside.

"Lao Liang, Uncle Du, you are injured, why don't you perform a good inspection?" Liang Sili is obviously heavier than Du Zhongkun, and the gauze wrapped around his shoulders is full of blood stains, and Du Zhongkun The hair and eyebrows were all burned.

These old guys really don't think of themselves as a thing.

When Liang Sili saw Liu Yijiu, his pale face squeezed a smile, "The place of the explosion was far away from us, and a piece of wreckage hit the launch vehicle..."

Looking at Liang Sili's gaze, Liu Yijiu's brow furrowed deeply. There was the wreckage of a launch vehicle over there!

"It's not that the missile does not have a warhead installed, and there are no flammable and explosive items on the launch vehicle. How can it burn?" Liu Yijiu asked with some confusion.

"Hit the fuel tank..." Du Zhongkun said with a wry smile, turning into a bald head.

This accident is unexpected enough!

"Xiao Liu, you came just right to help us analyze and analyze what caused it. Before launching the experiment, we used computer simulations many times. At the same time, many of these technologies are based on the 8208 missile. It stands to reason. , Our solid fuel technology is already very stable and will not explode... This time I don’t know where the problem is." Du Zhongkun said to Liu Yijiu with a wry smile.

Rocket solid fuel has always been the focus of research in the Ninth Academy.

Liu Yijiu originally proposed to use ammonium perchlorate (nh4clo4), plus no more than 18% aluminum powder as a burning agent, supplemented by 14% polymer hydroxy-terminated polybutadiene (htpb) as a binder, and A certain amount of nitroglycerin is added as a high-energy plasticizer to form a modified high-energy composite solid propellant fuel.

After years of research, the technology in this area has been quite mature.

In order to improve mobility, the missiles studied by the Ninth Academy are basically solid fuels.

Whether it's Black Arrow, Houyi, or even Sky Sword, all of them use this kind of fuel, and there has been no problem.

And after testing, it is difficult to explode.

"Did solid fuel undergo experiments and tests before being processed into grains?" Liu Yijiu walked around the wreckage at the scene. Under such circumstances, it was impossible to figure out anything at all, and the process was analyzed from beginning to end. , Even the inspection records have been reviewed many times.

There is no way to find out the problem.

"All are done in accordance with the regulations. The ratio is based on the above formula. I have simulated it with a computer. There are no problems..." Du Zhongkun was very big.

"What about the control system? Has the engine been tested?"

"All checked. Investigations have been conducted these days..." Liang Sili also smiled bitterly.

They have never encountered this situation.

Liquid propellant is easy to explode, but solid fuel undergoes complicated and detailed multiple inspections before being processed into grains and loaded into missile fuel tanks.

If the explosion did not occur, it would be very easy to find the cause of the explosion, but after the explosion, the various data monitoring devices above were also destroyed beyond repair.

"Try again." Finally, Liu Yijiu made a suggestion.

There is also a spare bomb, although in this case, if the cause of the failure is not found, it cannot be fired again, otherwise things will easily happen.

Liu Yijiu also had no alternative.

This project cannot be abandoned because it cannot be found.

The management committee is very cautious in this matter. After all, the missile is not something else. If the last experiment did not explode 8 seconds after lift-off, it would explode at the beginning. The core staff of the entire R&D team estimated that all of them would have to explode. scrapped.

In the end, the management committee approved the proposal, but required stricter inspections at every step, keeping records, and conducting relevant monitoring.

"At this time, we should stop and find the cause of the accident before continuing. Otherwise, even if the test is successful, we will not be able to find the problem. In this way, the design of this missile has serious hidden dangers and cannot be equipped. Inside the army..." Wang Shunyi hoped that Liu Yijiu could be more cautious.

It was not that Liu Yijiu was careless, but that the top technical teams of the Ninth Academy and the Ministry of Aerospace Industry were unable to detect the problem. Apart from continuing the experiment and obtaining more test data, there was no other way to work.

Liu Yijiu did not act arbitrarily on this matter either, but put Du Zhongkun and Liang Sili in charge.

"Or, let's carry out remote launch first." To ensure safety, Du Zhongkun made this opinion."Monitoring devices throughout the missile are remotely monitored, so that even if something goes wrong, or where there is something abnormal, it can be found..."

His plan is to use remote control devices to change the control device on the missile launcher to remote control.

At the same time, for the entire missile detection, remote monitoring is used.

In the previous tests, various detection devices were prepared to wait until the missile's fuel was exhausted before landing.A missile without a warhead will hit the target without exploding.

"This is ok. How long will it take to make such a modification?" Liu Yijiu nodded. This is the safest one. "Moreover, to avoid accidents, we should test the missile to the Northwest Gobi. Inside the venue."

In these places, although the route was chosen, it still passed through some villages.

"If you go there for a test launch, without satellite monitoring, there are not enough radar stations to detect it..." This is a huge problem.

The reason why I chose the test site here for the test launch is that from here to the intended launch area, radar stations for detection are built at intervals.

"This is not a problem. At that time, we will send a few planes for testing. Safety first." Liu Yijiu is now much more mature and stable than before.

Military research and experiments should not appear in the eyes of ordinary people.

If an accident occurs, it will cause irreparable damage.

"If this is the case, it is estimated that one month's time can be tested again. Many things need to be redesigned, although they are all ready-made." Du Zhongkun said to Liu Yijiu.

Liu Yijiu nodded and told them that during the test shot, the whole team followed into the Gobi.

No project can be accomplished overnight, and even many projects have bloody sacrifices in the development process.The Ninth Academy only encountered this once, and it was not unacceptable.Only the reason cannot be found.

Not waiting for Liu Yijiu himself to invest in technology research and development, he has been approached by the Iraqis who are about to go through Zhou Jun of the import and export trading company.

The war between them and Iran has gradually become calmer under the condition of Iran's increasing new fighters. Now the tired two sides have begun to sit together and discuss the end of the war in earnest.

The relations between Iraq and the United States and the Soviet Union have undergone tremendous changes due to the war.

They hope to re-negotiate with Liu Yijiu and decide to adopt Liu Yijiu’s original suggestions to them...
