The domestic 03 airborne combat vehicle unveiled at the military parade for the 70th anniversary of the National Day this year is the first tracked airborne infantry fighting vehicle officially installed in our army. Reequipment blank. So how was this iron armored eagle developed and produced? The
03 airborne chariot has a world-class bomb supply channel
The Type 03 tracked infantry fighting vehicle independently developed by my country is the first tracked airborne infantry fighting vehicle officially installed in the army. It fills the gap of our army's airborne heavy equipment. blank. The installation of the 03 airborne chariot has made the Chinese airborne troops' deep assault and firepower capability behind the enemy rapidly jump to the world's leading level , becoming one of the few countries that have mastered the heavy equipment airdrop technology after the United States, Russia and other countries. The
03 crawler infantry fighting vehicle
is inseparable from numerous components and accessories to ensure the advanced nature and actual combat capability of the 03 chariot. Among them, the turret system is an extremely important part of the weapon system. The weapon system of the turret part of the
03 airborne vehicle includes a 30mm gun, a 5.8mm or 7.62mm machine gun , a smoke tube device, and a missile launcher. The 30mm artillery can fire flat, hitting close-range living targets and some fixed targets; anti-aircraft can hit some low-altitude targets, such as gunships. Another feature of the 03 airborne vehicle turret is that it can rotate 360 degrees.
03 Airborne Chariot Turret Part
In order to learn more about the 03 airborne vehicle, a reporter from CCTV Finance's " Economic Half-hour " column boarded the turret, got into the gunner's position, and explored the mysteries inside the turret. The reporter saw that there is a rocking wheel that can control the artillery up and down. The other wheel is the 360-degree rotation control for the turret, which is very convenient to operate. Another major feature is that in order to ensure that the shells can be transported and not jammed, a special design of the ballistic transport path has been specially designed-irregular spiral shape, which can ensure that the shells can be transported without jamming and can be supplied smoothly. and this bomb supply system is also the first in China. Qu Zhanglin, deputy chief engineer of Chongqing Chang'an Industrial Specialty of
Weapons and Equipment Group, is the person in charge of this turret system and has been engaged in artillery design and production for 30 years. He said that this irregular spiral conveying trajectory is very difficult to develop. They took a long time to make a lot of experiments and prototypes, more than thousands of times. The current bomb supply system of has a high level of reliability, which is comparable to the international level. What is commendable about the is that the newly designed turret components, spare parts, and a feature can be used and interchangeable with some other turrets. Therefore, the maintainability and security of the shells are greatly improved. In order to highlight the striking effect, the
ammunition feeding system
also has innovations in the design of the shells. In addition to the original 30mm ordinary grenade, there is also a special kind of shell with high armor-piercing power - sub-caliber shell. Qu Zhanglin, deputy chief engineer of Chongqing Changan Industrial Specialty of
Weapons and Equipment Group: Compared with ordinary armor-piercing projectiles, the armor-piercing power of is more than doubled. The
armored aluminum alloy is equipped with an airborne chariot, and the weight is only steel. This hard indicator requires that the weight of the 03 airborne chariot turret system can only account for one-eighth of the weight of the entire airborne chariot. "Slimming" and reducing the weight of the turret system has become an important task.
Qu Zhanglin, Deputy Chief Engineer of Chongqing Changan Industrial Specialty of Weapons and Equipment Group : Our entire difficulty is weight loss. We tried composite materials, but the stiffness and strength of composite materials could not meet our requirements. Titanium alloys meet our requirements, but under the conditions at that time, the ablation resistance of titanium alloys is not very good. When it reaches a certain temperature, it will burn and be damaged.
03 airborne chariot
Just when the development technicians were trying to solve the problem, an exciting news made them shine. Our country has successfully developed an armored aluminum alloy, whose weight is equivalent to one-third of the general steel material , which solves the major problem of weight reduction, but the thickness of the aluminum alloy is thicker than that of the general steel material, soIn order to increase the difficulty of welding accordingly. It took nearly a year for the R&D personnel to solve the problem of welding difficulty. The body part of the
body is welded to the turret of the
03 airborne chariot. In layman's terms, it is the gun barrel. The scientific research and technical personnel said a little mysteriously that the grooves in the barrel were not processed by mechanical equipment, but were made by a special chemical method.
Li zhi, deputy director of Chongqing Changan Industrial Special Equipment Manufacturing Factory of Weapons Equipment Group: We process it by electrochemical corrosion.
Barrel
Whether it is a smoothbore gun or a rifled gun, the barrel must be straight. However, there is no machine equipment or instrument in the world that can completely replace manual calibration. The calibration of key parts of can only be done by experienced technical engineers. The two people
are testing are father and son. The ability to correct the straightness and smoothness of the barrel with just a pair of eyes is a unique skill that has been handed down to them for three generations. The father and son of
calibrated whether the barrel is straight or not. After the manufacture of the
barrel is completed, the next key link is the connection and assembly with the turret system. In the artillery assembly workshop, one of the difficulties in the final assembly of the 03 airborne chariot turret system is the consistency of the gun mirrors. The consistency of the gun mirror means that the high and low directions of the sight, the machine gun and the gun are synchronized and consistent. Judging from the actual shooting effect, where the scope is aimed, the gun and machine gun are shot. The
gun mirror consistently detects the
. Moreover, when the entire turret system is installed, the turret and the chariot are required to be on the same horizontal line as possible, which is another highly demanding unique skill. In order to ensure that the levelness is up to standard, the technicians use a professional digital level in the actual measurement, and its accuracy is 0.005 mm per meter.
digital level
In recent years, with the upgrading of new technologies, new processes and new automated production lines, the production efficiency of my country's military industrial enterprises is also improving, and the number of labor is decreasing. The has been upgraded from pure mechanical manufacturing to digital, Intelligent direction .
The new automated production line
Li zhi, deputy director of Chongqing Changan Industrial Special Equipment Manufacturing Factory of Weapons and Equipment Group:Our staff has been reduced from 4,000 people to less than 800 people now, but our production capacity has increased by 1.2 times .
Half-hour observation:
Over the past 70 years, my country's military equipment development has achieved world-renowned achievements. From the former "millet plus rifle" to today's mechanization plus informatization. The development process of the weapons and equipment of our people's army is a microcosm of the growth of China's industrial strength. Behind this is the selfless dedication of generations of researchers in New China. These important weapons of the country are not only the guardians of China and peace, but also witness the rise of great powers!
