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.
China, Qingtongxia.
A capable convoy of three vehicles was driving under the scorching sun along a newly built hardened road in the desert into an area marked as a "military important area, no one allowed to enter."
Lin Chenggang was sitting in the co-pilot of an Iveco car at the head of the car. He looked through the rearview mirror at a sentry who was being pulled further and further away by the convoy, and then spit out a mouthful of sand next to him.
"I really don't understand why you would set up the shooting range in a place like this..."
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.
Even though the doors and windows of the car have been closed tightly, fine yellow sand can still enter the passenger compartment through the circulation system and get into all exposed places such as the ears, nose, and mouth.
"What about this ..."
Cheng Guangwei, who was sitting behind the same car, smiled helplessly, but did not give a direct answer——
In fact, since the Horqin Sandy Land did not recede naturally, but was transformed into cultivated land and pasture in a planned manner under human influence, the cancellation of the Horqin Army Air Defense Weapons Experimental Range was quite sudden.
It was not until the shooting range was closed that the General Armament Department began to look for a suitable alternative area, and finally selected this Gobi desert in the middle of the northwest plain to avoid being transformed into farmland on someone's whim again.
Moreover, the newly built Qingtongxia shooting range will no longer be exclusively for air defense equipment, but will be suitable for all army firepower from individual rocket launchers to short-range tactical missiles.
However, considering that the "someone" in this incident happened to be the immediate boss of the other person's project, Cheng Guangwei decided to quickly switch to other topics:
"Actually here is good ..."
As he spoke, he tightened the gauze around his face:
"For the entire last year, we have been dealing with the almost abandoned Changli shooting range on the Air Force side. There is no decent road in that place. We have to take an all-terrain vehicle to get in every time. Even the night before departure. Don’t dare to eat…”
Lin Chenggang shook his head and did not continue in this topic.
In fact, in the eyes of a person who often served in the past, bumps and motion sickness are easier to adapt than dry and endless yellow sand.
Fortunately, he is not responsible for testing any specific model here, he is just here to verify the feasibility of a new technology 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 location is quite short, probably within two kilometers.
"Okay, hit!"
Lin Chenggang excitedly patted the instrument panel 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 this, there was no low-smoke or smokeless propellant that could be used on anti-aircraft missiles or air-to-air missiles in China...
Although Cheng Guangwei, who was in charge of the entire testing task, did not act so exaggeratedly, he also knew the unique technical content involved, so he stuck his head out and showed a knowing 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.
Let's celebrate together, it seems a bit inexplicable, and it's already 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 with the last missile that shot straight into the sky after ignition, this time it stood out in a slow and slow manner, slowly accelerating in a manner that was closer to an anti-ship missile than an anti-aircraft missile. This scene finally made the other people no longer need to be embarrassed, but exclaimed from the bottom of their hearts:
"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 there was a problem with the launch.
But the wake still extended steadily farther and faster, and it didn't look like it was out of control at all.
It wasn't until nearly half a minute later that a gorgeous firework exploded in the sky for the second time.
This time, Lin Chenggang in the co -pilot position even returned to him and hit his palm with Cheng Guangwei ...
……
As the so -called Wangshan runs to death, although the position of the missile launch looks not far away, the team still opened for almost 20 minutes before finally seeing the four missile launch positions deployed on the temporary highway-

In fact, from the beginning, only the new artillery and artillery-in-one air defense system that had undergone major modifications and been equipped with new missiles participated in this test.
However, with the successive 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 seeking a small -scale, simple structure, and large -scale endless defense missile for the carrier. The RIM116 "Ram", which is used to target the U.S. military, is almost over the dessert of the CT series pushing agent.
There is no mistake, one, one, one, one, one, one, one, one 619, one book, one, one, one, one, one, one, a book!
Due to the very small diameter (only about 130 mm), the disadvantage of poor mixed advancement agents and poor process costs are completely offset, and the advantages of fast combustion speed and high energy content are extremely suitable for short -range missiles.
However, the reason why Lin Chenggang came here despite the yellow sand and the bright sun today was because of another model.
Or strictly speaking, it is technology verified by another model.
It is about 50 meters away from that naval launcher, a chassis -shaped track -like air defense missile like the Toul M1 is rotating the launch tower.
From the perspective of the lids that have been opened and the unsatisfactory radar, the two missiles just shot just now should be this launcher.
Seeing the convoy filing in, Cheng Guangwei's assistant Liu Xiyun put down the mouse and jumped out of a nearby command vehicle modified from the chassis of an armored personnel carrier.
There was also a folder tucked under his arm.
"Mr. Cheng, Researcher Lin."
He jogged all the way to the front of Iveco. After saying hello briefly, he handed the document in his hand to Lin Chenggang who had just got off the car:
"Since this morning, we have conducted a total of six target tests for the anti-aircraft missiles that have been replaced with CTK-2 pushing agents in total. Type 2 pushing agent can show different flame -burning characteristics under different voltages. There is also a 0.8km unable to hit. The missile successfully ignited but lost power at the final stage. br>
Lin Chenggang nodded, and while listening to the other party's summary, he opened the folder and briefly browsed its 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 promoter can easily mix with sensitive materials such as hydroxylamine, such as the electrode and the power of the required voltage. Until the level of power off or voltage is reduced below the threshold level of combustion. As long as the electricity is turned off, it can be ignited and extinguished multiple times.
After a few tests, Lin Chenggang upgraded the formula, from CTK-1, which had only two states of ignition and extinguishing, to CTK-2, which can flexibly adjust the burning rate through voltage strength.
That is the model currently being tested.
The solid rocket motor using CTK-2 propellant can switch between fast burning-high acceleration-short range and slow burning-low acceleration-long range according to the actual situation, and it still has the ability to adjust the flight attitude through power at the end of the flight. .
In Lin Chenggang's view, the great work he had silently stood out should play an extraordinary role in the development of the inhalation of supersonic missiles in the back, thus becoming a key role in the entire R & D team in one fell swoop.
However, at this time, he still didn’t know——
Because the power is changed to a dual -modal super -burning stamping engine, the demand for rocket -assisted machines in the supersonal solution has been reduced to an unimaginable level ...
