The strongest rocket soldier

Chapter 54 Live Ammunition Operations
Looking at Ding Xiaojun's gone figure, the major officer looked at Zhao Shuqun's no-nonsense expression: "Zhao Shuqun, you, to be honest, are a good soldier, you are disciplined enough, and your performance in all aspects of the company is also remarkable. But do you know why you haven't made any outstanding contributions?"

"Hey, instructor, there's no one else, let's stop being so serious, come on, smoke a cigarette." Zhao Shuqun took out a cigarette from his pocket and handed it to the major officer.

"Be serious, let me tell you something." The major officer said seriously.

"Smoke one, the cigarettes from my hometown, so the fellow from Tanjia brought two." Zhao Shuqun pretended to flatter, and handed over the cigarette again. The major officer took the cigarette with a helpless look, and Zhao Shuqun Quickly took out the lighter again, the major officer saw that Zhao Shuqun looked like a villain and hated iron for not being strong, approached the burning fire, and ignited the smoke.

The major officer breathed out a puff of smoke: "Xiao Zhao, you have been in the technical battalion for four years before you were assigned. You are such an aggressive person. Look at you now, you are a little more mature than before, but you also It has become a dead class, too respectful of the way forward, people, you can't just imitate, blindly follow other people's old ways, you have to learn to be flexible."

"I know it's flexible. Isn't it necessary to show majesty in front of the recruits? I also think the vegetable field is well organized. It's just that it has changed all of a sudden. I'm not used to it." Zhao Shuqun said with a smile on his face.

"Crap, I don't know you yet. You have a more stubborn mouth than anyone else. What I'm talking about is not a vegetable field. I'm talking about learning to be flexible in everything. I'll let you in, that is, play the piano to a cow. Go back. I'm annoyed when I see you now. Go back and tell me Your company commander, this vegetable field is built like Ding Xiaojun, it looks comfortable, get out."

Zhao Shuqun got up and left, took two steps, then turned back and stuffed the cigarette in his pocket to the major officer.

"What are you doing, take it away, this is not popular in the army." The lieutenant colonel threw the cigarette to Zhao Shuqun again.

"Instructor, this is not bribery, but a normal etiquette in the old village. Didn't you tell me to be flexible?" Zhao Shuqun still had a playful smile on his face.

"Don't give me a hippie smile, it's not considered a bribe, is it?" The major officer's eyes fell on the familiar smoke again.

Zhao Shuqun looked indifferent: "It doesn't count, it's just a pack of cigarettes."

"Okay, let's go. I'll accept the gift from the old country first. However, there is a half pack of cigarettes. Bring me a whole pack later."

"Yes, instructor, it's nothing else, I'll go first." Zhao Shuqun just became serious, and then turned into a hippie smile again.

"Get off, get off, get off." The major officer put the cigarettes in his pocket, and went to the avenue opposite the vegetable field, followed by the book group, turned around, and slid out of the vegetable field like a frightened rabbit.

……

The training of the troops is over, and this day is the day of missile missile detection and flipping.Ding Xiaojun entered the missile magazine stationed by the camp management battalion with the team.

Let me explain here that Ding Xiao's unit is a strategic missile unit, mainly based on df21 series missiles, which have the characteristics of long range, high precision, high power, good maneuverability, and strong penetration capabilities. Its structure is complex and its technical content is high. , the price is expensive, and there is a prescribed service period after being equipped with the troops. In order to prolong the service time of the Army's campaign tactical missiles and save national defense funds, it is very necessary to regularly flip and compare the main factors that affect the storage life of the missiles and the ways to extend their service life. maintain.

The storage condition of the missile is the main factor affecting the storage life of the missile, especially the ambient temperature and humidity have a particularly obvious impact on its life. The change of the storage condition has several influences on the missile.

It mainly makes the solid engine age. Due to the difference between the solidification temperature of the solid engine and the operating temperature of the engine and the difference in the thermal expansion coefficient of the propellant, liner, insulation layer and other materials and the shell material, the internal stress of the material will eventually be at a certain level when the engine is stored. Fluctuations within the stress range, so that the engine grain is deformed, cavities or cracks appear, etc., affecting the internal ballistic performance of the engine (such as propellant burning rate, pressure, thrust, etc.), and temperature changes can also cause the sealing performance of rubber type sealing rings to deteriorate .

Excessive humidity will also seriously reduce the mechanical properties of solid motor propellants, and the surface of the propellant exposed to high humidity will become soft and cracked, and may also cause debonding between the solid propellant and the liner.Practice has proved that the debonding between the solid propellant and the liner directly affects the combustion characteristics of the propellant, and may cause the engine to explode when it is serious.

The second is the failure of the electronic products on the bomb. The impact of the environment on the electronic products is mainly to make the thermal stability and insulation performance of the electronic products poor. The harsh environment will cause the integrated operational amplifier, the distortion of the magnification of the transistor, and the reduction of the insulation performance of the capacitor and the relay.

During the service period of the missile, the troops should regularly inspect the missile according to the requirements of the technical documents. The inspection contents mainly include appearance inspection, function inspection and performance test. If it is serious, it will damage the equipment. In the technical position, missile assembly professionals should master the basic knowledge of missile assembly mechanics. If they do not operate according to the specified torque requirements, the screws may be damaged or broken; if they do not strictly master the methods and skills of missile docking .

The good ambient temperature for missile storage is between 10 and 25 degrees, and the relative humidity is below 60%. This knowledge is not what Ding Xiaojun should learn, but what Ding Xiaojun heard from the technicians while working in the ammunition depot.

The work of the loading company does not include the work on the storage environment and the performance of various external instruments, and is mainly responsible for the maintenance of the missile body.

The mass of the missile itself is very large. During the storage of the magazine, it is placed on the rack. Long-term storage on the rack will cause excessive force on the conductor side of the missile, and some factors that affect the life of the missile will appear. A missile needs to be turned over once, and every time it is turned over, it is necessary to carry out comprehensive maintenance on the various components and internal components of the missile.

"Ding Xiaojun, this time, you are in charge of the No. [-] position. You have never made any mistakes in your training. This time, it is a live ammunition operation, not an experimental ammunition. You must be careful, careful and careful, and don't make even the slightest mistake. , understand." Zeng Xiang once warned Ding Xiaojun.

"Yes, squad leader, I must be careful, strictly follow the rules, and never make mistakes." Ding Xiaojun immediately became serious.

"The trumpeter is in place,..."

The operating area of ​​the magazine immediately became busy. The assistant trumpeter of each missile department handed various tools back and forth to the main trumpeter on the operating handle, and took the parts from the main trumpeter one by one, and put them back into the instrument box.

"catch!"

"it is good!"

"catch!"

"it is good!"

The entire magazine has been echoing with the work passwords of the trumpeters.

Standing on the operating platform, Ding Xiaojun did not dare to be distracted, and concentrated on his own operation. Except for the cooperation with the assistant trumpeter, everything else seemed to have nothing to do with him.

Four hours later, the trumpeters of all parts have completed the operation. Next, the dismantled components and parts will be tested. With reloading, just after meals.
