Chapter 1333 Variable Thrust Solid Propellant

Compared with the wonderful air over time on the vast Pacific Ocean, and the twisted brains of high -temperature gas dynamics at both ends of the earth, some people's work is relatively unknown.

Huaxia, Bronze Gorge.

A dry team consisting of three cars is under the scorching sun and drove into a area marked as "military place, leisure -free from entering" along the desert.

Lin Chenggang was sitting in an Iveco co -pilot, looking at a sentry sentry who was pulled away from the team more and more through the rearview mirror, and then spit a sip of the sand in his mouth.

"I really don't understand, why do you set the shooting range in this kind of place ..."

As a technician who has been engaged in the naval missile for half a lifetime, he asked himself to go to many three or four types of regions with harsh environment, but he has never experienced such a natural environment.

Although the doors and windows of the car have been closed, the fine yellow sand can still enter the occupant cabin through the circulation system, and drill into all places such as the ears and nose mouths.

"What about this ..."

Cheng Guangwei, who was sitting behind the same car, smiled helplessly, but did not give the answer directly-

In fact, because Korqin sand is not naturally fading, but is planned to be transformed into cultivated land and grass fields under human influence, the revocation of the Korqin Army's air defense weapon experimental shooting range is also a very sudden thing.

It was not until the shooting range was closed that the General Equipment Department began to find a suitable alternative area, and finally selected this desert Gobi in the middle of the northwest plain, so as not to occur again when someone's heart was transformed into a farmland.

In addition, the newly built Tong Tongxia shooting range will no longer be specifically faced on air defense equipment, but is suitable for all the army firepower from single soldiers to short -range tactical missiles.

However, considering that the "someone" is the top boss of the other party's project, Cheng Guangwei still decided to quickly switch to other topics:

"Actually here is good ..."

He said the scarf wrapped tightly on his face:

"In the whole year of last year, we were all taking the Basic Changli shooting range with the Air Force's side. There was no decent way in that place. Dare not eat ... "

Lin Chenggang shook his head and did not continue in this topic.

In fact, in the eyes of a person who often got on the ship in the past, bumps and motion sickness are easier to adapt than dry and endless yellow sand.

Fortunately, he was not responsible for any specific model testing here, but came to verify the feasibility of a new technical route.

So it doesn't need to be treated.

At the same time as Cheng Guangwei's voice fell, Lin Chenggang saw a touch of fire flying out of the distant horizon with a touch of fire, and then inserted the sky directly.

After about 1.5 seconds, there was a light of light flashed in the air in the air, indicating that the missile had hit something.

This flight time also means that the distance between the target and the launch position is quite short, which is likely to be within two kilometers.

"Okay, it's in China!"

Lin Chenggang patted the instrument table in front of the co -pilot.

Although people's eyes cannot directly capture such a clear image in such a long distance, even if only through the appearance of the dust that still remains in the air, he can distinguish that the missile must use the latest type of test pushing agent developed by himself.

Because before that, there was no kind of smoke or smoke -free pushing agent that could be used on air defense or air missiles ...

Although Cheng Guangwei, the entire test task, was not so exaggerated, he also knew that the unique technical content in it, showing his head to show a smile.

On the one hand, the other people in the car can see similar scenes almost every day, and they have been numb. On the other hand, I don’t know what this is testing, so the two people are shocked. I have to be overwhelmed.

Celebrate with it, it seems a bit inexplicable, and it is too late.

But both Cheng Guangwei and Lin Chenggang are both leaders. If they are doing it, they are not like that.

At this subtle moment, the same position just raised a faint white feather smoke again.

Yes, it is "raising".

Compared to the direct insertion of the cloud after the previous missile was ignited, this time it highlighted a unhappy, and slowly accelerated the attitude of closer to anti -ship missile instead of air defense missiles.

In this scene, the other people finally didn't have to embarrass it anymore, but instead exclaimed from the heart:

"ah?"

There is no obvious sound explosion over the dry desert area. Such outrageous visual effects even make it difficult for people to judge whether the missile has exceeded the speed of sound.

For a moment, they thought they had problems with launch.

But the ending still extends steadily towards a farther place, and it is getting faster and faster, not like out of control at all.

It was not until half a minute later that the air exploded for the second time a gorgeous firework.

This time, Lin Chenggang in the co -pilot position even returned to him and hit his palm with Cheng Guangwei ...

Nympho

As the so -called Wangshan runs to death, although the position of the missile launch looks not far, the team still opened for almost 20 minutes before finally seeing the four missile launch positions deployed on the side of the temporary highway--

In fact, at the very beginning, only the new missile-in-one air defense system that had undergone a major modification and was equipped with a new missile participated in this test.

However, with the development and production of CT-1 propellant and its improved CTK-2 propellant, several other models belonging to the army and navy have participated.

In particular, the navy is looking for a terminal defense missile with a small size, simple structure and large ammunition reserve for destroyers and frigates to match the US military's RIM116 "Ram", which is almost exactly on the sweet spot of the CT series propellants.

No mistake, one song, one post, one content, one 6, one 9, one book, one bar!

Due to its extremely small diameter (only about 130 mm), the disadvantages of poor shaping ability and high process cost of the mixed propellant are completely offset, while the advantages of fast burning speed and high energy content are extremely suitable for the performance of short-range missiles.

However, the reason why Lin Chenggang came here today in the yellow sand and the sun was because of another model.

Or strictly speaking, it was the technology verified by another model.

About 50 meters away from the naval launcher, a tracked anti-aircraft missile with a chassis similar to the Tor M1 was rotating its launch tower.

Judging from the opened cover and the radar that had not yet been retracted, the two missiles that had just been fired should have been fired from this launcher.

Seeing the convoy coming in one after another, Cheng Guangwei's assistant Liu Xiyun put down his mouse and jumped down from a command vehicle next to him that was converted from an armored personnel carrier chassis.

There was also a folder under his armpit.

"Mr. Cheng, Researcher Lin."

He trotted to the front of the Iveco, and after a brief greeting, he handed the file in his hand to Lin Chenggang who had just got off the car:

"Since this morning, we have conducted three rounds of six target tests on air defense missiles equipped with CTK-2 propellants. Five of them successfully hit targets ranging from 1.5km to 25km, proving that CTK-2 propellants can show different burning rate characteristics under different voltages. There was also a 0.8km target that failed to hit. The missile successfully ignited but lost power in the final stage. The dud has been safely recovered and the reason is being analyzed."

Lin Chenggang nodded, while listening to the other party's summary, he opened the folder and briefly browsed the contents.

CTK-2 propellant is a model he further developed based on CT-1 inspired by Chang Haonan's ideas.

CTK, which is the abbreviation of super-high energy-control.

Due to the unique characteristics of solid-liquid mixing, the matrix of the CT series propellant can be easily mixed with electrically sensitive materials such as hydroxylamine nitrate. When electrodes are installed and the required voltage power is applied, the solid propellant ignites and continues to burn until the power is off or the voltage drops below the threshold level of combustion. As long as the power is on and off, it can be ignited and extinguished multiple times.

After a few tests, Lin Chenggang upgraded the formula again, upgrading the CTK-1, which only has two states of ignition and extinguishing, to CTK-2, which can flexibly adjust the burning rate by voltage strength.

This is the model currently being tested.

The solid rocket engine using CTK-2 propellant can switch between fast burning-high acceleration-short range and slow burning-low acceleration-long range according to actual conditions, and still has the ability to adjust the flight attitude through power at the end of the flight.

In Lin Chenggang's view, this big job that he has quietly done should play an extraordinary role in the development of air-breathing hypersonic missiles in the future, thus becoming a key role in the entire R&D team in one fell swoop.

However, he didn't know at that time that -

Since the power was changed to a dual-mode scramjet engine, the demand for rocket boosters for the air-breathing hypersonic solution had been reduced to an unimaginable level...
